Hey y'all

So, I hear the 7870 is the card of choice these days due to a pretty solid price/performance ratio - which is half the reason for doing eGPU. I was hoping you could spread some light on the whole overclocking/stock model and brand differences. I've always used laptop gpu's, so this OC'ing is new to me.

1) There's about a $25 to (sometimes) $75 price difference for the same GPU that is OC'd vs not... Is this really worth it? Can't you just do the OC'ing yourself, get the same result and save some money?

2) Also, what's the big difference and what should I be looking for when it comes to engine clock vs memory clock? Is 800 MHz good enough for an engine clock or should I be looking for a something closer to 1000 Mhz? does it make a difference if you can overclock it yourself?

3) I can pick up a MSI R7950 Twin Frozr 3G (800Mhz/5000Mhz) for less than $300 right now. This seems like a really good deal, but I'm not entirely sure what I'm getting myself into vs. an XFX 7870/OC for $70 cheaper...

I realize that this might not make much of a difference in an eGPU setup, but I'm hoping that the new 4x TH05 version next year will change all that.

The x4 TH05 will make no difference over the current x2 TH05 with existing Thunderbolt-equipped systems.

Why? We've just discovered all x4 2.0 capable boxes (Magma, OWC, Sonnet) send Thunderbolt traffic at x2 2.0 + 12.5% bandwidth levels. The 12.5% extra they get over a x2 2.0 TH05 is hardly worth them commanding 2.5-times or more the premium over a TH05. Have to wait until 20Gbps Thunderbolt arrives in 2014 OR we miraculously figure out how to use the second 10Gbps Thunderbolt channel for pci-e rather than it's default of displayport traffic to get x4 2.0 running.

Please refer to my HD7870 versus GTX660 on x1.1, x1.1Opt, x1.2, x1.2Opt review to help make your eGPU purchase decision. If you would be running x2 2.0 Thunderbolt then yes, AMD cards do better in restricted bandwidth scenarios once we factor out the pci-e compression that's only available on x1 links.

Another important consideration is if you need internal LCD mode. Then you'd evaluate NVidia Optimus vs Lucidlogix Virtu. Both require a primary iGPU video bootup device so ensure your candidate notebook has it if that feature is important. NVidia Optimus is part of the driver set and is free. LucidLogix officially only has a 30-day trial version.

Recommend a HD7870 or GTX660Ti

So for current Thunderbolt-equipped systems suggest grab a US$180 BPlus TH05 + AMD HD7870 or NVidia GTX660Ti.

Thanks nando, i didn't had to use diy setup at all. I just disabled dgpu in bios,and hook up expresscard and it immediately shows picture on external monitor.

So i have HP 4530s with i5 2410m soon to be upgraded to i7 2630qm, and i also upgraded screen to FHD. Really awesome laptop.

My 3dmark11 score NVIDIA GeForce GTX 660 video card benchmark result - Intel Core i5-2410M Processor,Hewlett-Packard 167C score: P5026 3DMarks

Farcry 3 is flying with fhd and ultra details at 35-55fps.

3dmark11 says the GTX660 is running as the primary video so you may be seeing x1 2.0 rather than x1.2Opt (x1 pci-e compression + internal LCD mode). Can confirm by running 3dmark06. If the result is < 10k then you're running the slower x1 2.0. Usually need to hotplug the eGPU after boot or set the PCI Reset jumper to do it for you to get the HD3000 as the primary and [email protected] running.

Can see my Dell E6230 + GTX660 @ x1 2.0 and x1.2Opt results for performance differences.

Out of curiosity-why do you list display port as a disadvantage over hdmi?

I guess the ppl I spoke to always preferred HDMI over DP. I read that DP is preferred in a business environment but didn't see an elaboration as to why. Apple now having HDMI ports on their latest Macbook Retinas where previously they had TB/mDP only ports. Dell Latitudes also having HDMI rather than DP.

Yeah it looks like the trackpoint doesn't fit into that design. Or rather it would have fit if they got rid of the trackpoint, but for some reason (marketing?) they decided to go with a touchpad instead of a trackpoint.

Yeah the refurbished laptops are a bit cheaper ($600+ on E6230 for "certified refurbished"). HP 2170p new ones start from $1000 and the only Elitebook they're offering on their Academic website is 8770w (wtf...).

I'm with you and would have preferred a touchstyk over a touchpad. That way the hands never have to leave the keyboard. Though can see it would have been a dealbreaker for some then. 2170P pricing makes little sense - a 2570P can be bought for less. With their weird US pricing it almost looks like HP don't want to sell business notebooks to consumers.

Great comparison!

Latitude E6230 is the only one from the new Latitude series (with rounded edges so to speak) that looks acceptable to me. Unfortunately, I don't think it can compete with Thinkpad X230 at all, due to its insane price alone -- its about $500 more expensive than the X230 in the US (almost double the price). It also doesn't seem to have a trackpoint (I guess thats what you meant by touchstyk ), like X230 and 2570p and I really prefer it over classic touchpad.

I am hoping that they come out with better features like Brian mentioned in their next generation.

Agreed. A E6230 is the only one without the ugly orange accents so is the most stylish of the current Latitudes.

I am stunned by Latitude pricing in the US. The E6230 can be had for significantly less than the other two as a refurb in Australia. Here the 2570P is the dearest unit. imho too, it was a major oversight to not include a touchstyk on the E6230. Though I can see why by evaluating the E6230 vs E6330 keyboard below. See the trackpoint mouse buttons? They would have encroached into palmrest/touchpad space. I'm guessing the E6330 keyboard + touchstyk (without buttons) could be retrofitted to a E6230. What's the point without buttons? Maybe Dell could make the touchpad a clickpad when running in that configuration?

<A href="http://www.msystems.gr/files/product/14618.2.jpg"><img width=49% src=http://www.msystems.gr/files/product/14618.2.jpg></A> <A HREF="http://ww2.notebooki.wroc.pl/upload/e6330-8.jpg"><img width=49% src=http://ww2.notebooki.wroc.pl/upload/e6330-8.jpg></A>

Above: E6230 and E6330 keyboards compared

A E6230 has 3 mPCIe slots of which none are wired for mSATA. Dell really should have added a touchstyk and mSATA to their E6230. A IPS LCD option would be appreciated too.

HP also have a 2170P which looks like a smaller 2570P. It does have a touchstyk. It deviates from the ultrabook design by offering a removable 48Whr battery, 7mm 2.5" SSD/HDD, business grade build, matte LCD. Comes with a backlit LCD. Still it misses out on mSATA and what were HP thinking giving it only 48Whr?

So yeah.. I too hope the next generation of ultraportables from these vendors can incorporate the full feature set (mSATA, IPS, Thunderbolt, touch, touchstyk) and more.

I was aware of middleton's BIOS, but I hadn't heard about the X9100-E0 CPUs.

Does the upgraded CPU have any further effect on the performance of the eGPU setup? Or is it just done to gain overall system performance?

Also, is there a well-known source for them? Or is scavenging eBay my best bet?

Overall system performance would improve. RickiBerlin lists advantages/disadvantages with his X9100-E0 CPU (QHBQ) installed in a HDX9000: *HP HDX 9000 DRAGON Owners Lounge, Part 2* - Page 457 . The X9100 is a Series-4 CPU that can be made to work in a 965PM system by doing a 266->200Mhz socket pin mod. It's the coolest/fastest CPU you can get for your box. Cheapest I've seen them is on aliexpress for US$140-shipped: wholesale & retail Intel Dual Core X9100 QHBQ laptop cpu QS Version-in Processors from Computer & Networking on Aliexpress.com . You might get lucky on fleabay.

When evaluating all of this, consider what an complete system swapout would cost to a s/h Sandy Bridge system. Eg: Lenovo E420/E520/T420/T520, HP 4430s/4530s/6460b/6560b/8460p/8560P, Dell 3450/3550/E6420/E6520. There you'd get x1.2Opt performance from your GTX570 which would outperform your x2 1.0 with the T61 and be a simpler single-cable solution. The eGPU parts are cheaper too. The notebook itself would be considerably faster and give better battery life. Only downside I see is you'd be going to a 16:9 LCD.

My ideal ultraportable is a super light weight Ivy based one (with user replaceable CPU socket) that also has a foldable touchscreen with a wacom digitizer so that it works seamlessly with Win 8. Ideal size would be about 13" IPS or even AMOLED (which are coming very soon) with WIDI/WiHD capabilities. It should also have a thunderbolt port which a lot of these notebooks lack. I'm guessing there has to be 1 or 2 ultraportables with this configuration coming to market soon.

The ultraportables listed in this comparo are from the last generation. A lot has changed since then with a rise in expectations - retina displays, cheap Nexus tablets, Win8, Thunderbolt. I too would love a feature set as you list. Unfortunately the first - upgradable CPUs looks to be on the way out. REF: http://forum.techinferno.com/general-notebook-discussions/2490-intel-might-kill-cpu-upgrades.html

I too am looking for a similar feature set in the next wave of ultraportable releases.

Putting tape on pin 20 worked like a charm.

I was actually planning on trying to do the x2 eGPU port3+port4 configuration using the 3rd mPCIe half-slot and the ExpressCard slot. I was trying to move the wifi card to port 1 because I read that when I set port3+port4 to x2, it would change port1+port2 to x2 as well, meaning that the wifi card would no longer work on port 2. Of course, it may not work on port 1 with x2 enabled, either. That's the next step of my testing.

I'll be using my GTX570, so I don't think the x2E thing would work.

I see.. that would be a convenient configuration. Your wifi card should work OK in port1 in x2 mode.. it will just use the first lane. Yes, x2E doesn't apply to you when using a GTX570.

There are lots of T61 users out there. Having a confirmed x2 eGPU configuration extending their lifespan. There's also a dual-IDA bios getting you another free 200Mhz: See middleton's Ultimate R61/T61/X61/X300 BIOS (inc SATA-II)

If wanting to take it a step further, you could put a X9100-E0 stepping CPU into it giving 1st gen i5 levels of performance when overclocked using Throttlestop software and unlocked multipliers.

A competitor site has been moulding public opinion with a moderator there proclaiming repeatedly the Lenovo X230 is the best ultraportable on the market with no mention of either a Dell E6230 or HP 2570P as alternatives. Questioning that opinion may even get you banned.

As there are no sponsors on here to bias our recommendations, we can objectively evaluate all the pros and cons of these ultraportables below from which you can decide for yourself which features set best suits your needs. The notebookcheck.net reviews linked below are the very best available but do not cover some of the details below. So as not found on notebookreview.com, here's a pros/cons list of these three business ultraportables.

12.5" Lenovo Thinkpad X230 REVIEW

+ dual-drive capable: mSATA + 7mm 2.5" HDD/SSD but both are more expensive than 2.5" 9.5mm counterparts

+ 94Wh 9-cell battery option

+ backlit keyboard AND Thinklight

+ 54mm expresscard slot so can host an external eGPU for accelerated graphics/processing

+/- IPS LCD option. A pro/con depending on your needs. Pro: wide viewing angles and high brightness. Con: wide viewing angles bad for privacy, draws more power and there are reports of red appearing as orange and image ghosting.

+/- Displayport rather than HDMI port, a pro/con depending on your needs

-- quality issues with palmrest cracking above expresscard slot disintegrating, battery rattling around

- poor styling that hasn't evolved from their 1990s Thinkpads. Lenovo have spent $0 in the styling department.

- non-upgradable soldered CPU

- short palmrest may be uncomfortable if have large hands

- touchpad has no real physical mousebuttons, it's a clickpad

- whitelisted WWAN/wifi slots preventing use of future comms standards. I believe a hacked bios exists to get around this.

- Lenovo safeguard prevents use of cheaper aftermarket batteries -> need genuine Lenovo ones.

- eGPU users cannot get 16GB configuration to work -> need to downgrade to 8GB.

12.5" Dell Latitude E6230 REVIEW

+ contemporary styling

+ traditional keyboard with backlight option

+ do not whitelist their WWAN/wifi slots

+ easy servicability by removing bottom cover giving access to all major components

+ 34mm expresscard slot so can host an external eGPU for accelerated graphics/processing

+/- HDMI rather than Displayport, a pro/con depending on your needs

- no touchstyk

- non-upgradable soldered CPU

- no IPS LCD option but retrofit performed successfully here

- only single 7mm 2.5" SATA SSD/HDD capable

- no 9-cell battery option, rather uses a slice.

12.5" HP Elitebook 2570P REVIEW

++ socketted CPU -> can be be easily user upgraded to faster dual or quad cores but confirm warranty implications

++ optical drive. Can be replaced by caddy hosting a 9.5mm 2.5" SATA SSD/HDD alongside the primary 9.5mm 2.5" SSD/HDD.

++ supports RAID-0 across 2x6Gbps internal SATA channels for very fast SSD/HDD performance

++ exceptional build quality and contemporary styling

+ 100Wh 9-cell battery option

+ 34mm expresscard slot so can host an external eGPU for accelerated graphics/processing

+ easy servicability by removing bottom cover giving access to all major components

+/- Displayport rather than HDMI port, a pro/con depending on your needs

+ glass touchpad

-- heavier and thicker than the above two

- no IPS LCD option

- whitelisted WWAN/wifi slots preventing use of future comms standards. No hacked bios is possible due to RSA protection.

- no backlit keyboard option but has a nightlight

Summary

A Dell E6230 is somewhat more stylish than the X230 but has the least features of the lot. A Lenovo X230 has some great features, if you can live with it's uninspired styling and some quality issues.

Which brings us to the best unit from this lot. Given the massive move to smartphone/tablet mobile computing, having a complimentary 2570P offering near-desktop performanace levels when upgraded (CPU+storage), yet mobile enough to take on the road means it's the most potent tool from this set. It's also the significantly better built unit too.

So, I pulled my wifi card from port 2 and moved it to port 1 and it no longer works. Basically, it's detected and everything, but when I go to the adapter settings page, there is a red X over the signal bars and it reads "Not Connected". If I click on the signal bars to connect, the list never populates with any access points.

So, I tried pressing Fn+F5 to see the status of the radio. Sure enough, it was set to "Off" despite the switch on the front of the laptop being turned on. However, when I click the "Radio On" button in the dialog, the radio remains off.

Essentially, something is forcing the radio off when the wifi card is moved from port 2 to port 1. Moving it back to port 2 returns it to normal.

Has anyone seen this behavior before? How can I get the radio to turn on with the card in port 1?

Good news that wifi registers when moving over to the other mPCIe slot as port1. Means you could do a x2 eGPU port1+port2 configuration using your two mPCIe slots. In fact, if using an older AMD card (HD4xxx/HD5xxx) you could run x2E mode (port1+port2 electrically connected, but port1 set to x4 mode) which would give full duplex x2 1.0 performance. It's a way to rectify some handshaking bug between your Intel ICH8M IO chipset and these cards. I am not sure if HD6xxx/HD7xxx are equally affected.

To force enable the radio on your wifi card just put cellophane tape over pin20. That should see it working in port1.

Further update:

So I think I've narrowed it down some more. My C:\ is on an mPCIe mSATA drive. I think that when I do a PCI compaction, the mSATA drive is getting clobbered and I'm losing access to it. Setup 1.10b5 shows me three PCIe devices:

1) Ricoh,

2) Intel, and

3) Nvidia.

The Ricoh is almost certainly the mSATA drive. How can I preserve it's PCI address (or whatever I need to preserve) when doing compaction?

First things first. When you boot into Setup 1.1x, can you chainload to your OS before doing any PCI compaction?

@sgogeta4 you are thinking exactly what I am for an ideal notebook except I'd want a true e-gpu made by a big company like nvidia that utilizes thunderbolt or some proprietary connection that takes full advantage of pci-express bandwidth.

We discovered in the eGPU area that current Thunderbolt is limited to x2 2.0 + 12.5%. The GPU itself negotiates a x4 2.0 link with the Thunderbolt controller on premium products like the Sonnet/Magma x4 2.0 TB enclosures, but there are two 10Gbps Thunderbolt transfer channels and one is reserved for Displayport traffic. Disappointed that we cannot make it a single 20Gbps channel instead. Maybe some reserved PCI registers could be hacked to do that if we got the TB datasheets from Intel? We know for sure that 20Gbps Thunderbolt that could transfer x4 2.0 bandwidth will come in 2014.

Summary then is, current Thunderbolt eGPUs have just over double the bandwidth of Sandy/Ivy Bridge expresscard versions. It's questionable value then to spend the extra $$ for the TB-to-pcie enclosure/adapter and then seek out a Thunderbolt-equipped notebook from the handful available.

I wish it wasn't so. Saying that . . .

I too want a tablet or touch-based ultrabook with matte LCD that's thin and equipped with a x4 2.0 Thunderbolt port for eGPU purposes. 11.6" Acer Iconia W700 is the closest match with it's i5, IPS-1080P touch LCD and Thunderbolt port: Acer Iconia W700 review | Tablets Reviews | TechRadar

Hi, i have some problems with my HP 4530s. I finally got all the parts, i have gtx660. My 4530s is with dgpu hd6490m, and i have booted diy setup,disabled dgpu,run compaction 32a,and chainloaded to win.

I installed the lastest drivers from Nvidia,and gtx660 doesn't have any errors but my intel hd3000 have code 43,and i can't get picture to my external lcd.

I have seen people run gtx card on my lap also with dgpu hd6490m.

If anybody have the steps neccesary to work.

Thanks.

Suggest (1) don't perform PCI compaction, just disable the dGPU and chainload. If still no go then (2) delete the Intel+AMD switchable graphics driver you have installed and just install the latest Intel HD3000 driver and try again.

i've already build my eGPU. imgur: the simple image sharer

just that the performance isnt as good as i thought it should be. i also want to hold off till Haswell come out but want to know what i can do now to make the GTX660 dont perform like a intel4000

Per my previous post, replace the GTX660 with a HD7870.

Some Studio XPS 1640 are already listed on the first post @x4, but if you insist i can give you all the details of my config, But please, just tell me if it will be usefull to PCI compress my config even everything works well without using it.

PCI compaction is only required if you have an error 12 against your eGPU preventing it's operation. That does not apply to you.

so are there anything i can do for my vaio cw 26 atm? or its doomed to have such low performanceuntil i change lapotp.

I noted in my recent i5-3320M + GTX660/HD7870 testing here that AMD eGPUs no longer appear to be crippled to half duplex performance on that Series-7 chipset as previous HD5750 cards were on a Series-4 chipset. I know that you'll see a much better 3dmark06 result with something like a HD7870. I'd be curious to see you do the same comparative performance tests on your system so we know if these newer AMD cards are indeed better performers across DX9, DX10 and DX11 on older Intel chipsets.

Still.. you can see the difference in performance going from a x1 1.0 to x1 2.0 (Sandy/Ivy Bridge) gives in that link so a system upgrade is the other option to consider as noted earlier.

Hello everybody, Can I get an explanation about what's the use of a PCI Compaction ? I've got a PE4H with a GTX-560 Ti connected on a Dell Laptop, The eGPU is @x2, and everything works nicely without PCI Compaction.

Refer to the Setup 1.1x help on PCI compaction available online or by pressing F1 in Setup 1.1x: PCI compaction

If your Dell is running a x2 configuration and isn't listed yet on the first post, then can you please provide full details so it can be? Not many x2 configurations atm.

hi, thanks for your swift reply. i would like to have ivy bridge w iGPU, expresscard, <= 1.6kg, 13/14 inch, 1080p. any suggestion?

i was all over vaio z3 few months ago other than it doesnt have expresscard slot. then on the verge of buying r930 but then hold back because of 1080p. just waiting for the right one to come.

12.5" Lenovo X230 (1.45kgs, 768P-IPS)

13" Toshiba R930 (1.48kgs, 768P)

12.5" Dell E6230 (1.59kgs, 768P) IPS-LCD-mod

13" Macbook Pro Retina (1.62kgs, 2560 x1600, Thunderbolt)

14" Lenovo T430s (1.77kgs, 900P, Thunderbolt)

14" Toshiba R940 (1.9kgs, 900P in US)

12.5" HP 2570P (1.9kgs, 768P, socketted CPU/45W quad capable)

So closest match is a MBPr or consider a 13" Sony SVZ (1.18kgs, 1080P) but with the mPCIe mod: http://forum.techinferno.com/diy-e-gpu-projects/2158-diy-egpu-guide-sony-vaio-vpc-z2-svz13.html . Best compromise might be a 12.5" Lenovo X230 with it's 768P IPS LCD or 12.5" HP 2570P if need 45W quad CPU power. I'm not a fan of Lenovo Thinkpad styling given it hasn't changed much from the 1990s...

Bit of a off-topic note...

Imagine the capabilities of this eGPU setup >> 25-gpu-cluster (25x AMD HD6990) LOL!!!

I wonder if there is a way to leverage this Virtual OpenCL cluster platform in eGPU implementations. Dreaming :P

There's also fastraII, the NVidia version from a few years back. 6xGTX295 + 1xGTX275, 13 GPUs total = 12TeraFlops of computing power. We have done the DSDT override so have no 32-bit limitations to host the eGPUs. Just need a expresscard/TB bus extender to host so many eGPUs to do the same with our notebooks. It would of course still be limited by the bus bandwidth. Not sure how much is required for computational purposes but would guestimate it would be a lot less than for gaming.

I followed your guidance few months ago and has recently finished building my egpu. But when I run gpuz, it shows im running on pci-e 1.1 only although I bought the PE4L 2.1b

Im using cx430 psu, vaio cw26, twinfroz MSI gtx 660, PE4L 2.1b. any advice?

also when i run 3dmark06 its super horrible, about 5k points only (i did run gpuz behind to double check if it is running on the right card!)

my laptop is cw26 sony vaio

everest shows that my gt330m is using PCI E 2.0 and 3d accelerator is set to gt330m, iGPU not activated.

Your CW26 is a Series-5 system. It's PCIE 1.x only for the link speed, but PCIE 2.x for power management. In addition you have no iGPU so no Optimus pci-e compression. You are seeing straight x1 1.0 link performance which is pretty bad for a NVidia card when using DX9.

The weak link in your configuration is the notebook. Replacing it with a Sandy or Ivy Bridge one with an iGPU and expresscard (eg: 14" HP 8460P/8470P, Dell E6420/E6430, Lenovo T420/T430) would gain you x1.2Opt performance (x1 2.0 + NVidia pci-e compression). 3dmark06 would be over 18k then with your GTX660.

Now I get Error 43

I've done as in troubleshooting:

1.done

2.done

3.

- Boot eGPU Setup 1.x,

- select Video cards->Load to load the PCI space dump created when it was working with no error 43. Done then press f3 to load in Setup.bat ( don't know if I should but it gets deleted after next step anyway)

- perform 32-bit PCI compaction on the iGPU+eGPU. 32-bit or 32-bitA All its not working. I can only do a 36bit for all and force one on 32bit (I've tried both in turns)

- select startup.bat->edit, remove the 'call vidinit' since it might interfere with your load dump. Done

- select Apply config.Run startup.bat Done

- select Chainload mbr Done

Error still there but moves from eGPU to dGPU depending on PCI compaction.

Its there any setting I'm missing here?

Thanks for your help

Try the Video cards->Initialize function first after PCI compaction. If still get an error 43 then it may be because you have both a NVidia dGPU and eGPU. In which case I'd suggest modify the Verde (mobile) driver set to include your eGPU so as to get a unified driver set for both GPUs.

Yeah looks like this is a new product: PE4H V3.2 (PCIe x16 Adapter)

A couple of notes for why it may not change the product we'd have chosen (PE4L 2.1b):

• You can only use video cards where the PCI-Express power connectors are on the end of the card rather than the side (the maority of high performance cards have them on the side -- my GTX 660, for example)
  
• I don't believe there's any performance difference (still limited by the ExpressCard I believe, PCI-Express x1 2.0 -- someone correct me if I'm wrong)
  
• The power adapter is only 120W. I'm unsure if that would be enough for many of the higher performing cards (even though Kepler is more power efficient). From the looks of it you could also just use a normal ATX power supply and connect the 24-pin connector to it, but IMO that kind of defeats the point of a nice enclosure when you have your PSU with all its wires out in the open
  
• It's more expensive. You're getting more than just the PE4L, sure, but I paid $78 for the PE4L, $17AR for my PSU, and I'm thinking about a cheap mATX case to stick it all in -- ~$35). Plus this setup is more flexible
  

It does look pretty nice though and is more reasonably priced than the ViDocks. Perhaps it would be a great fit for a card like the GTX 650/650Ti (PCI express connectors on the end, and possibly within the limits of the 120W adapter). For comparison, many people have used a 203W XBox power adapter (needs to be modded though) -- maybe hwtools will make a higher powered adapter available in the future

Correct. A PE4H 3.2 provides the same x1 2.0 (pci-e) performance as a PE4L 2.1b. It's advantages over a PE4L 2.1b being mostly packaging:

1. an enclosure for the video card

2. ability to use all power form dual/tri rail ATX PSUs

It's negatives are:

1. it costs considerably more than a PE4L 2.1b

2. it continues to use a 19V DC input for those wanting DC power for the slot. That means that hot bridge rectifer remains. PE4L 2.1b uses straight 12V.

3. if using an enclosure then the video card must have pci-e power from the side rather than top.

A PE4L 2.1b + modded XBOX360 PSU still gives the best bang-per-buck portable solution imho.

I got everything ready and then got stuck at my first step.

First of all my system is:

inspiron 1720

Tolud is 3.5gb and I got in to some problems trying to do DSDT override . Basically my .dsl file its nothing like the one in the guide and I can't find the PNP0A08/PNP0A03 'DWordMemory' resource entries.

What am I doing wrong?

Insert the code as shown in Avlan's E4300 dsdt override example.

One question -- how can I confirm that Optimus is working? I know in the NVidia control panel I can see the option for the 2 GPUs, but I know Nando on his ATI/NVidia comparison in a note mentioned: "Achieved by powering the eGPU before starting the system". Does this mean if I start my X220 from a shutdown state with the eGPU in there, it will not use Optimus? So the only way is to add in the eGPU resuming from sleep or hot swapping?

Confirm you have the Select preferred graphics processor for this program option in the NVidia control panel as shown below:

Different system bios handle the startup differently if the eGPU is detected. My understanding is the latest X220 bios will just lower TOLUD and boot with the iGPU as the active primary video device. My Dell E6230 would set the eGPU as the primary video device on bootup if it was detected on poweron. To get x1.2Opt engaged, with the iGPU as the primary video device, the eGPU needed to be hot plugged or activated using the PCI Reset Delay jumpers so it was on the pci-e bus *after bootup*.

Are Sony SVZ/SZ2 PMD users getting x2 2.0 links?

Hi Mikjoa,

We recently discovered in http://forum.techinferno.com/diy-e-gpu-projects/2513-how-we-measure-rank-describe-our-systems-no-more-%401-2opt.html thread that Thunderbolt is currently limited to x2 2.0 + approx 12.5%. So if a user purchases a Sonnet Thunderbolt enclosure the eGPU will register a x4 2.0 link but get bottlenecked downstream by the Thunderbolt<->Thunderbolt comms.

Now I know the Sony SVZ/SZ2 guys were noting poor performance from their PMD. Could you ask them to run CUDA-Z (NVidia) or PCieSpeedTest (AMD) on their PMD eGPU and submit the results? We are seeing approx 400MB/s on a x1 2.0 link. So they'd either see 1600MB/s (x4 2.0) or if they too are being crippled in a similar way to a x2 2.0 link then they will see 800MB/s (device-to-host).

EDIT: This was confirmed via PM. The PMD runs a 10Gbps link just like 2011-2013 Thunderbolt, equivalent to x2 2.0 + 12.5% bandwidth.

This is really disappointing. Why did they solder everthing together? I already have 1x EC2C and 2x PM3N and 3x mini-HDMI cable, so for me it would have been nice to just buy the connector itself. Right now I don´t need it but my next laptop will be an Ivy-Bridge-laptop of course and then i would need the PE4L not my PE4H :/

BPlus tried to get pci-e 2.0 going but it would fail when there were mHDMI connectors involved. That's why they soldered it all together to eliminate those connectors. You'll note they have a variation, PE4L-L060A 2.1b which is their newer board allowing attachment to the older EC2C or PM3N. I was advised this too couldn't negotiate a pci-e 2.x link.

The approach then is to consider offloading your current pci-e 1.x specced PE4H 2.4 + EC2C + PM3N and get a pci-e 2.0 specced PE4L-ECxxx/PE4L-PMxxx 2.1b when you get your Ivy Bridge notebook.

Oh... Damn, I tought it was a ExpressCard slot. I expected to not open my laptop but whatever... Then I'll need the PM060A version, now some last questions and I think I'll be ready.

This software doesn't comes bundled if I buy from HWTOOLS? Because PM060A package is not at HIT.

Standalone software from HIT is digital download? (To avoid taxes)

So I get better perfomance by disabling the GT650M instead of doing an optimus config?

So the GTX660Ti is my limit? Or a higher end videocard will also work? I expect to try a GTX680/690.

With this I will still get a x2 bandwith setup?

Thanks a lot for answering guys!

In order to get x1.2Opt (Optimus) (x1 2.0 + pci-e compression) functionality on the eGPU instead of the GT650M dGPU, the NVidia dGPU needs to be disabled. Use Setup 1.1x to do that. You can go higher than a GTX660Ti, like a GTX670/680 but will need to ensure an adequate power supply to drive it. Avoid twin-GPU cards like a GTX690 since so far no one has got it to work and it requires more resources to accomodate it. A PE4L-PMxxxA 2.1b is the only solution available to you since you have no expresscard slot.

Seems like a great review, but I can't help to think it's also quite a bit biased: the reviews that don't mention any cons are totally not to be trusted imo.

I also disagree with comparison to T430. T430 is a heaver 14" laptop, and 2570p can be directly compared to X230 instead:

- 2570p looks more sleek I suppose

- 2570p has much worse TN screen with average brightness of 166 nit (cd/m^2); conveniently left out from the review [ref: notebookcheck.com review]. This is a bit low compared to the average of 264 nit for IPS screen on X230. The viewing angles are listed as 150 degrees -- I have to say I laughed at this part since I know the laptop comes with a fairly poor TN screen.

- 2570p has replaceable CPU, but it is unclear to me through how many CPU generations this will last (my point is by the time you'll need faster CPU there will be much faster CPUs from subsequent generations on the market)

- 2570p runs 10 C colder than X230 (80C vs 90C) on full load. This is to me a fairly better and probably the biggest advantage.

- as configured X230 with IPS screen comes about $690+tax through Lenovo Barnes&Noble website (this is around $800 or just slightly below if you add that + shipping).

The way I see it, for $50 more (say X230 is $800 after taxes and shipping) you get a sexier looks and replaceable CPU, but a far worse TN instead of IPS screen (and you need to purchase 2570p from a fairly unknown third party merchant; otherwise the price will go up by ~$100). The cooling is a bit better in 2570p. Apart from that, 2570p and X230 are pretty much the same and the question becomes whether one is willing to trade the IPS screen (and $50) for improvements in other places.

I believe the reviewer compared it to a T430 because a 2570P weighs in close to a T430. It's heavier weight and HP's whitelisting of WWAN/wifi ports are the other disadvantages of a 2570P. Though I believe Lenovo whitelist their wifi/WWAN ports but unlike a 2570P, a hacked bios is usually available as a workaround.

You are on the mark with advantages of a 2570P plus do note that a 2570P can accomodate a 2.5" 9.5mm primary drive + either a optical drive or a second 2.5" 9.5mm primary drive via a caddy. A X230 uses a 7mm 2.5" drive + second mSATA drive. So a X230 has lower storage capacity with it's 7mm/mSATA drives which also happen to be higher cost per GB than their 9.5mm cousins.

A 2570P's upgradable CPU means if one puts a 45W i7-quad into it they'd get the smallest, most powerful system available in the current gen. Supports SATA-III RAID-0 across it's two drives (2.5" + 2.5" via optical caddy) too giving a very fast storage subsystem to match.

Gadgetsnute, a NBR Dell E6220 user dismissed a X220 because of it's looks but wanted the IPS LCD. He ended up retrofitting a IPS LCD into his E6220. REF: Latitude E6220 IPS screen replacement . I wonder if the same can be done with a 2570P/2560P? If HP offered IPS on their 2570P then it would be a no brainer for me - a X230 with it's dated looks and less durable build wouldn't even be on the radar.

In any case, a 2570P is a good one to keep on the radar once it trickles into the s/h market for it's upgradable CPU feature and business grade durability. Best if it still has some remainder of the higher-specced 3yr NBD onsite global warranty.

+1 Frula's comments. If you have a dv6-7084la then it has no expresscard slot. Only way you can attach an eGPU is using a mPCIe wifi slot. For that you'd need a PE4L-PM060A 2.1b. A GTX460-1MB is significantly faster than a GTX550Ti so it's a good one to get s/h. Otherwise a GTX560Ti or GTX660Ti. You'll also probably need Setup 1.1x software to disable the DV6's GT650M so can get the faster x1.2Opt performance. Recommend then you purchase your gear via Harmonic Inversion (HIT) to get the software bundled with your hardware. Only I'm not sure if they keep the PE4L-PM060A 2.1b.

Tech Inferno Fan July-2015>> Anybody interested in the 12.5" 2570P should also consider a 14" Dell E6430. The E6430 is the superior performance platform due to it's 900P LCD option, NVidia dGPU option, unlockable turbo bins (+400Mhz) on i7-37xxQM/i7-38xxQM CPUs and x2 2.0 eGPU capability. All with a minor size/weight penalty. See http://forum.techinferno.com/dell-la...tml#post118135 for details.

Performance upgrade: i7-quad CPU resulting in 'IVB ZBook 12' or 'EXtremeBook'

Can effectively double the CPU performance going from a factory i5/i7 dual core to a i7-quad CPU. Could also be desirable if you wish to lower fan noise and temps. Running a i7-quad with max 99% CPU utilization results in noticably cooler temps than their dual-core counterparts without loss of performance, eg: cool i7-quads by bjorm's i7-3632QM or Aikimox's i7-3840QM. Note: warranty implications of a CPU upgrade - a factory-specced faster dual core up to i7-3520M 2.9 will not void warranty while a i7-quad will void the warranty if HP know about it as it wasn't offered with one. I'd keep the original CPU back and swap it back in if necessary. Upgraded 2570P i7-quad system examples are shown in the table above.

NOTE: A 45W CPU can have highest multiplier limited to a 35W CPU level using Throttlestop software. That means a 45W i7-3630QM/i7-3610M (turbo=3.4/3.3Ghz) runs like a 35W i7-3632QM/i7-3612QM (turbo=3.2/3.1Ghz). Best 45W i7-quads being a i7-3630QM (x32) , i7-3720QM (x34) and i7-3740QM/3820QM (x35). There is at max 9% 4-core peformance difference between these with the higher end ones often not being able to maintain their upper multipliers as shown here. Meaning, suggest grab whichever is available and of lowest cost in your area.

The 4-core TDP limit means any faster 45W CPUs do not see any gains. If need more performance and have deeper pockets then consider purchasing a 55W i7-3920XM instead. It has an additional 10W heatroom for turbo. Though it will absolutely need cooling mods to be able to accomodate at that level. <- 55W CPU is being limited to 45W on a 2570P as shown.

It's possible to get and install cheaper PGA-to-BGA converted i7-quad CPUs as demonstrated by pandaleo.

Performance upgrade: external graphics (eGPU)

DIY eGPU to attach a desktop videocard via the 2570P's 5Gbps expresscard slot. Provides accelerated gaming graphics, CUDA/OpenCL processing and additional HDMI/DVI outputs to drive multiple monitors. 

To do this most users only need to set System configuration->Device configuration expresscard slot from Generation 1 to Generation 2 as shown below:



A NVidia GTX460/560/660/670 is a straight plug-n-play implementation on a 2570P when using Windows 7, though Win8.x is problematic (src: here). Win8.x users may consider doing a UEFI installation instead which resolved error12 and gave hotplug capabilities as noted here.

An AMD card, GTX650, GTX750, GTX9xx or older NVidia cards require a DSDT override and (maybe) DIY eGPU Setup 1.x interposer software to eradicate error 12 that prevents their functionality. See the 2570P DSDT override details if using one of these cards.

Implemented on a 2570P at x1.2Opt speed (5Gbps + compression) using a NVidia GTX670 (jacobsson), GTX660Ti (Tech Inferno Fan), GTX560Ti (bjorm), GTX660 (dewos), GTX560Ti (hatoblue), GTX650Ti (phillofoc)
