By the way, has anyone found out if BIOS rollback is possible after F.50? That would really help.

Take a full bios dump of the eeprom using the Intel FPT utility, do your > F.50 flash. If can't do rollback using the HP flash utility then can use the FPT to load your old bios back on. The full procedure to do this is described at http://forum.techinferno.com/hp-business-class-notebooks/2537-12-5-hp-elitebook-2570p-owners-lounge-13.html#post65904 .

I'm at F61-something and am wondering whether there's a point in trying to rollback, other than just to use your DSDT patch file.

Thing is, I'm using Windows 8.1 on MBR, was considering converting to UEFI, but am really having a whopper of a time figuring out the DSDT patching and the ASPM patching as well. I'm trying to edit the dsdt.aml file I dumped with acpidump, but I see none of the same types of strings and don't know what to delete.

Then I switched to DSDT Editor and there's 144 errors preventing me from compiling and saving the file. I'm trying to find a DSDT clean-up guide but am having some trouble.

I want to run a GTX-970 at some point in it, although the first card I'll be using with it is a r9-270x.

EDIT: Got an error-free dsdt.aml using acpidump and iasl. Trying to load it in now to see what happens. After which I want to enable ASPM somehow.

EDIT2: SUCCESS.

Huh. This was so easy. I just needed to move one entry from the DSDT to another place in the file and it compiled right off, i have the large memory entry in device manager now. So I should be good to use pretty much any eGPU right now?

I wonder, is PE4H better alternative for 8470p than PE4L?

8470p has 3 PCIe ports(EC, Wifi, Modem), all running at 2.0, so in theory x2.2 link should be possible (10gbps).

2570p has only one PCIe running 2.0, the rest is 1.0

2570p has only one PCIe running 2.0, the rest is 1.0

All PCIe ports on the 8470P/2570P are Gen2 capable since are hosted off the Southbridge. More to the point is finding a combination that allows x2 2.0 to run. That means port1+2, port3+4, port5+6 or port7+8.

Imho, you're better off getting a Dell E6430 than one of these HP systems for your intended purposes. They have a proven x2 2.0 link working at http://forum.techinferno.com/dell-latitude-vostro-precision/9690-14-dell-latitude-e6430-performance-upgrades-system-mods-2.html#post130202 . Furthermore, they allow a lot more CPU performance tweaking. Eg: a i7-quad may be able to run it's unlocked turbo bins: http://forum.techinferno.com/dell-latitude-vostro-precision/8176-%5Bguide%5D-dell-e6530-cpu-tdp-multi-unlocking.html#post111576 . Overall, a better candidate system for higher i7-quad and eGPU performance.

That's out of question now :D .

It took me whole 6 months (and a lot of sweat) to build those machines to my liking with over $2000 spent.

Dell also comes without Displayport (only HDMI) which is unacceptable for my setup.

eGPU, while good addition to those builds, is not to be considered primary reason for getting them.

New version of HWInfo now reports 2.0 as well.

#1 seems to be Wi-Fi

#2 ExpressCard

#35 JMicron SD reader

So x2.2 might be possible after all, however I'm not entirely sure if it's worth the extra $40 to find out.

Port 1 seems to be WWAN on 2570p (based on 2560p schematic). Paired with Expresscard on Port 2 might be possible, provided WWAN is not whitelisted, but it is. :(

2570p has unbridged SATA rather than pcie pins in the WWAN slot to give it a msata electrical link. Unfortunately bios msata support was never added. Likely the 8470p followed that same design.

Actually mSATA might be possible on 8470p, as the sata pins are connected. I believe I read somewhere that mSATA can be used as cache drive for RAID-0 setup on 8470p. However it's not bootable and no SSD get recognized under OS.

Nice work there. I'll add that there an even simpler way of accomplishing this. That's by creating a patched MBR that does these memory writes. You can get an idea of what's involved by reviewing this post: http://forum.techinferno.com/desktop-storage/2108-diy-adding-ssd-hdd-storage-using-optical-bay-caddy-%5Bver-2-0%5D.html#post38289

Sry, don't have a 2570P anymore.

Anybody else want to have a go at a ASPM MBR patch to help kpyhere and other 2570P owners maximize their battery life?

Could someone who has successfully hooked up gtx 670 through the express slot using a 2.1 adapter shed some light unto what I may be doing wrong? All I have to do is plug it into the adapter, hook up my 12v rail from the ATX into the adapter, plug it into the EC slot right? If I run it like that w/o setup, I get code 43, if I use any combinations of setup 1.3 it hangs.

I thought 670 was the way to go, and after finally acquiring one today.. I've dumped hours upon hours into trying to get it going and nothing >< Using 350W ATX P/S; had it going at first but screen was unstable, figured it was a driver issue, did a fresh reinstall of everything (video drivers, setup 1.3 etc.) and now the best I can do is get to windows loading screen > black. I thought it's supposed to be easier than 750 TI with a clean dsdt but nothing I do seems to work - really bumming me out =/

Hiya,

I was/am using bplus 2.1a PE4L. I have it working with 750TI (after a lot of work) but just couldn't get it going. I couldn't even hot plug start it, so the more I think about it, the more I think it was the power supply (350 watts but for all I know, it could be running at 50% of it since it's a crappy one). If it's not that - I ordered a new one that should arrive today or tomorrow but if it's not that, I guess I'll have to order another adapter and make sure it's 2.1b this time as I hear 2.1a can give issues. I'm also not sure if I'm connecting it properly - am I supposed to connect from the adapter to the 2 3-pin connectors on the top or is it already getting sufficient power through the 12v?

What amperage does the PSU theoretically provide on the 12V rail?

Have you tried setting the ExpressCard slot to Gen1 speed in BIOS to confirm it's not due to signal issues? Unfortunately, I'm not sure how the ATX PSU should work precisely - I think you should use the 12V from the PSU directly into GPU, and use one molex-to-floppy cable to power the adapter.

Hey, the amp was around 16a (too lazy to get up to check) - I bought another 400w PSU with 22 amps and higher reviews and no change.

I'm pretty sure the card was either a dud or I shorted something by connecting the cables. Like, I couldn't even start it (edit: this is after I had it initially 'running' with monitor flickering and all - again not sure how exactly I did it but it did 'work' so yeah maybe a dud - maybe usps threw it around too much cause the seller didn't write fragile on it) by hot plugging during startup, tried with switches at 2 and 3 and only then the fan would spin but eventually nothing. When you say 12v from PSU into GPU you mean into the adapter right, because the GPU itself only has 2 6-pin molex inputs. Either way I had tried all kinds of combinations and eventually it just gave out.

I'm going to buy another 670, brand name this time, and if still nothing - maybe it's the adapter itself in which case I'll just have to suck it up and buy another adapter.

I didn't realize there was a 2.1a and 2.1b versions until much later - the one I bought off amazon simply said 2.1. But yeah.. the a is like outdated or whatever and gives a lot of people problems so =/

p.s. yes tried gen1 and all that.

Once i get another 670 (trying to find a ftw evga or msi pe oc one) I'll post the update here.

I'm sorry if this topic already came up, but does anyone know if the IPS-Panel from the Elitebook 820 fits into the 2560p/2570p? It's an LG LGD0404, here is a test of it. It is vastly superior in every category and I would cry tears of joy if I could get it into my 2560p.

Well, I just looked it up and the screen from the Elitebook 820 would fit but sadly it has a different connector (eDP) then the 2560p (LVDS). :72::72::72:

Ok, so as far as i can tell, you power the adapter through a molex 4pin-to-floppy connector on the adapter (correct me if it's not there), which also supplies the card up to around 75W through the PCIe slot. And you give extra power to the card, using standard ATX PSU GPU power connectors, or molex-to-6-pin, into the card, directly.

I hope for your sake @Tech Inferno Fan chimes in, because I'm only guessing based on what I've read so far, I didn't actually get any adapter yet.

//Oh, now it works. Well.

Does anyone know how the cooling from the 2560p and 2570p compare? They look a little different. I would guess the one from the 2570p performs slightly better?

Got a 2570p now and made a comparison between RAM running with 1600MHz and 1866MHz (both times 2x4GB and running with CL11). Processor I used is an i5-3320.

Sandra Memory Bandwidth:

1600Mhz: 19.16 GB/s

1866MHz: 20.13 GB/s (+5%)

3DMark06:

1600Mhz: 5970

1866MHz: 6161 (+3.2%)

Not really amazing, but since both kits (8GB) cost the same here (both around 50€) I would pick the 1866MHz kit.

I wanted to build an Intel Ultimate 6300 wifi card into my 2570p, but unlike my 2560p it only has 2 antennas for wifi... Anyone know if I can just use one of the UMTS antennas instead?

@OeffOeff your 1866mhz ram is probably running at tighter timings than you think. Usually when faster RAM is running at a slower speed the timings are tighter. I have this kit:

G.SKILL Ripjaws Series 16GB (2 x 8G) 204-Pin DDR3 SO-DIMM DDR3 1866 (PC3 14900) Laptop Memory Model F3-1866C10D-16GRSL - Newegg.com

and when I look with HwInfo my timings are 9-9-9-28. No idea if that would result in a 3% increase, but I'm sure it helps.

For your wifi card, you could give it a shot with using the WWAN leads for your 6300. I don't think the antennas have a good spread for MIMO, as WWAN antennas are usually right next to the WIFI ones, and I've seen laptops that will delete the camera if you use one of these 3x3 cards to allow for the third antenna to be in the middle of the display. If you don't have the card yet, it may be worth looking at getting either the Broadcom or Intel AC wifi WLAN cards so you can get an AC router when you're ready to upgrade.

On another note, I'm probably going to attempt the IPS screen swap that has failed before. If I can't move the driver board that's on the bottom of the LCD, then I'm going to use a board like this one Amazon.com : sunkee M.NT68676.2A (HDMI+DVI+VGA+Audio) LCD/LED Screen Controller Board Diy Monitor Kit (Please remember to leave us your LCD Model Number before placing the order) : Car Electronics to make a DIY monitor.

Worth noting too, @timohour has done some comprehensive RAM benchmark tests (1333 vs 1600 vs 1866 vs 2133Mhz) at http://forum.techinferno.com/dell-latitude-vostro-precision/9690-14-dell-latitude-e6430-performance-upgrades-system-mods-4.html#post131341 . That was on a Ivy Bridge 14" Dell E6430 with XMP RAM profiles enabled. Not sure if the 2570P can use 2133Mhz RAM.

      We've had a stack of recurring questions from with problems getting a mPCIe eGPU working. This includes GPU-Z not reporting no clock details, error 10/43 or even not being detected at all. Overall it's more troublesome getting mPCIe working than say expresscard or Thunderbolt.
       
      Here's some common problems and some troubleshooting steps to correct them.
       
      Getting a black bootup screen, resolving error 10/43 or ACPI_BIOS_ERROR win bootup messages
       
      Here the BIOS doesn't know what to do when it sees an eGPU. So the solution is to not let the BIOS see it. Do that by setting the delays on the eGPU adapter (CTD/PTD - EXP GDC or CLKRUN/PERST# on PE4L/PE4C). Boot with eGPU adapter in the wifi slot into Setup 1.30 or Windows. Is the eGPU detected?
       
      I'll add that should error 43 continue AND you have a NVidia dGPU as well as NVidia eGPU then it's likely because of having the mobile NVidia and desktop NVidia drivers loaded simultaneously. Proceed to uninstall ALL your NVidia drivers, use "DDU" to clean NVidia registry entries and do a 'clean' install of the latest NVidia desktop driver.
       
      mPCIe port that hosted the wifi card disappears when connecting an eGPU in it's place
       
      Use the Setup1.30 PCIe Ports->enable to enable the missing port.
       
      eGPU does not get detected
       
      Overcome mPCIe whitelisting by booting with the wifi card and then hotswapping in the eGPU. That way the BIOS will enable the mPCIe port to work.
       
      1. Boot with wifi card into Windows, sleep system, swap wifi card for mPCIe eGPU adapter and ensure eGPU is powered on, resume system. Do a device manager scan in Windows. Is the eGPU detected?
       
      2. Boot with wifi card into Setup 1.30 *carefully* hotplug the eGPU adapter in place of wifi card. Hit F5 to rescan the PCIe bus. Is the eGPU detected?
       
      If this enables detection then avoid this tedious hotswapping by seeking a unwhitelisted modified BIOS for your system OR test the Setup 1.30's PCI ports->undo_whitesting feature.
       
      eGPU still not detected - set the PSU to be permanently on
       
      The latest EXP GDC and BPlus eGPU adapters try to manage the PSU to only power on after they detect a signal. This can cause a race condition where the eGPU isn't ready to go when the CLKRUN signal is asserted.
       
      Avoid this by jumpering the PSU so it's permanently on rather than being managed. Depending on the PSU you are using refer to the following doco on how to do that:
       
      http://forum.techinferno.com/enclosures-adapters/8441-%5Bguide%5D-switching-atx-psu-using-paperclip-trick-swex.html
      http://forum.techinferno.com/enclosures-adapters/9426-220w-dell-da-2-ac-adapter-discussion.html
       
      eGPU still not detected - a non-standard mPCIe implementation by your vendor?
       
      PERST# mPCIe pin 22 may need to be isolated due to a non-standard implementation by your notebook vendor: http://forum.techinferno.com/enclosures-adapters/10812-pe4x-series-understanding-clkreq-perst-delay.html#post142689
       
      eGPU still not detected - faulty hardware?
       
      If you still don't get detection then test the video card and eGPU adapter in another machine to confirm neither is faulty.
       
      NVidia driver stops responding
       
      EXP GDC, PE4H 2.4 and PE4L 1.5 all use a socketted cable and therefore are not true Gen2 compatible device. This error indicates there was transmissions errors.
       
      The solution is either to get a better Gen2-compliant eGPU adapter such as PE4C V3.0 or PE4L 2.1b (both with soldered cable), or downgrade your link from Gen2 to Gen1 using BIOS options or Setup 1.30

      Required items:
      1.) Lenovo u310 (I have a Core i3 - Ivy Bridge, 8GB RAM)
      2.) 65CN99WW unwhitelisted.
      3.) eGPU (I used a EVGA GTX 750 Ti from another computer I had).
      4.) EXP GDC mPCIe Edition adapter (got from eBay - banggood seller).
      5.) ATX power supply (I used a 600W PSU from another computer I had).
      6.) USB wireless.
      7.) External monitor, keyboard, and mouse.
       
      Steps:
      1.) Obtain and install a unwhitelisted BIOS. If you are unable to obtain a unwhitelist BIOS, I think it might be possible to bypass it with Tech Inferno Fan's Setup 1.x (may need confirmation as I haven't used it myself yet.)
      2.) Shutdown computer and remove all USB devices, ethernet cables, power cables, card reader cards.
      3.) Remove mPCIe wireless card and detach antennas.
       
       
      4.) Attach EXP GDC external mPCIe cable to the former wireless slot and screw down.
       
       
      5.) Attach HDMI end of the mPCIe cable adapter to the EXP GDC device.
       
       
      6.) Attach graphics card to the EXP GDC device (I moved my laptop off the desk and onto the side shelf to make room on the desk for the monitor/keyboard/mouse).
       
       
      7.) Using the power cable adapters that came with the EXP GDC device, I hooked in my ATX power supply's 20 pin and CPU 4 pin cables. Then hooked the other end (8 pin) into the EXP GDC device. My EVGA 750 Ti also required that I use an additional PCIe power cable (6 pin) in the top of the card.
       
       
       
       
       
      8.) Then I attached my misc devices (HDMI monitor, USB keyboard/mouse/wireless adapter), and hooked in my PSU and powered it on (below is image of final product, also moved HDMI cable out of the way).
       

       
      9.) Power on your computer and let it install the standard VGA drivers and then install your drivers (I didn't have to go in the BIOS for any graphics settings, which it doesn't have anyways, nor did I have to disable iGPU in Device Manager before the card was added).
       
      Extra Info:
      I found that most games will play on med settings with about 45 FPS with this particular card.
      BDO: Upscale on - Anti Aliasing on - SSAO off - med settings.
      Skyrim: Med-High settings.
      Fallout 4: Med settings.

      Hello, A couple of days ago I got a new GPU but when I installed it into my computer I was unable to use it but now I know why. When checking the device manger I went into the events tab of my GPU when I went to view all events, I noticed an error it said " event 411 kernel PnP " and It also said Problem Status: 0xC01E0438. I believe this is why my GPU hasn't been working on my PC. If you know how to fix this problem or have info on how to fix this problem that would be greatly appreciated. I'm also using a EVGA NVIDIA GeForce GTX 1660.

      I'm having a problem where my PC is saying my eGPU is not usable, its detected in the Device Manager and it doesn't have the yellow triangle next to it. I cant use it games and the Nvidia Control Panel doesn't recognize it either. I'm using a EVGA NVIDIA Geforce GTX 1660. I'm using windows 10 and I tried DDU and reinstalling them and now I cant access the nvidia control panel. The GPU is not recognize on any other apps and I went on *********** and was unable to find my answer, Any help on how to fix this problem would be greatly appreciated.

      Title sums it up.
       
      TL;DR: we have a Clevo that runs a desktop CPU, one with those huge 82 Wh batteries. We remove the GPU and let it use the CPU's integrated graphics. How much time for the battery to go from 100 to 0? Is it comparable to an ultrabook's?
       
      I'm theorizing a mobile set with a static eGPU and an upgradable CPU. Given a hypothetical user that needs fast processing on the go and long battery life while retaining very high degrees of mobility, but at home wants a powerful machine to run most games, I guess that would be their best bet. It would surely be more convenient to keep everything in the same disk. And even though the thing would be quite heavy to carry around, changing CPU would be more cost-efficient than changing an entire laptop. (Not sure if I'm right here, and also I'm not sure whether the motherboard in a Clevo would be replaceable when the new CPU needs a different socket, which is another reason why I'm asking here.)
       
      If my above guesses aren't correct, then an ultrabook with Thunderbolt and without a dedicated GPU would be a better choice. If they are, then we would be carrying more weight in exchange of a more cost-efficient setup, which I think would be a fair tradeoff.
       
      Also I am aware of the heating problems that these laptops suffer from, at least compared to a desktop setup. Would they be solved by moving the GPU out of the chassis, and instead plugging it with an eGPU dock via Thunderbolt port?
       
      What do you think? Is it doable? If not, why?
