Yeah I have the same issue with my 960 but I really don't want to give up my internal display until I get a 3rd monitor

Hello I have a hp8470p on win 8.1 and 10 have always code 12 with setup 1.30 have pci error allocated.

I tried

dsdt overrided but have more than 200 errors pls help 

Hello, try installing windows 8.1 /10 with UEFI (in bios enable UEFI without CSM) Don't try to use setup 1.3x with UEFI

With this method, the kepler based Nvidia (gtx 770,780,680,670) should work with no problem without dsdt override.

Other cards like nvidia 9xx (maxwell based) and 750Ti require windows based DSDT override, see https://www.techinferno.com/index.php?/forums/topic/1982-125-hp-elitebook-2570p-owners-lounge/&page=14#comment-66892

Hello. 

Can you post the chipset and motherboard temperatures of your 8470p during load?

I noticed this notebook uses a part of the chassis to cool it, unlike the E6430. I may want to get a quad core later so I got curious about this.

My Vostro 3550's chipset gets over 54°C idle, 75°C while gaming on the dGPU. There is also an unknown "Auxiliary2" thermistor in hwinfo64 that is always a little hotter than the other parts when idling (65-75°C). The CPU (i5-2430m): 55-90°C

Hey, I no-longer have this setup. I never had cooling issues with my 8470 with a quad core

Looks like the GTX 970 requires some different memory address space to the 770, not working under win 8.1 UEFI or windows 7 BIOS mode

<strike>And it seems that my Setup 1.x link has expired, can Nando send me a new link so I can get this card working? I can provide proof of Donation if you need via PM @Nando</strike> <--- supplied

I saw it posted and was surprised at the low numbers. One number I was looking at is the GTX770 one. The linked table lists the TDP of GTX770 as 195W but officially it's 230W. techpowerup measured it at 214W here.

If a GTX770 owner would use that table as a reference they'd think they are well within the power constraints of a 220W Dell DA-2 PSU supplied with a EXP GDC V6/7 or BPlus PE4C V2.x, yet the reality would more likely see power starvation with BSODs or complete shutdown under fulll GPU load.

Yep, that 170w (hopefully) gtx 970 cant come soon enough for me. I just sold my 770.

Ill post benchmarks when I get the new card

ALSO, there is a reasonable difference between reference and non reference GTX 770s, with non reference cards generally consuming more (with their higher clocks, higher power limits, beefier cooling and VRMs they will boost higher than reference cards

Hmm, Maybe Ill wait for a more power efficient card comes around. I don't like the sound of throttling

Regarding the EXP Enclosure, I see that it says 29cm long, now my gpu is around 29cm +- 0.5cm (it's a 770 ref) Correction, its only 26cm

My hope is to cram my 770 into is. Has anybody tried this? I am desperate for a smaller enclosure than my current shuttle pc case.

I understand that the DA-2 probably isn't powerful enough for my card but I think I can get that under control with undervolting and reducing the power limit, otherwise I will swap it for a 680 or 970

Anyone have any ideas? Has anyone else purchased the Enclosure??

I tried them all at highest settings cause I was quite confident that the games where quite old and 3GB of GPU is such overkill but I noticed something, I was expecting FPS to be constant and stable (eg COD MW2) but it is quite choppy when looking at persons around..I wonder why

I was having major issues with MW2 FPS was very choppy at any graphics setting, at all low I was getting better performance with my HD4000.

I would assume this is something weird with their renderer or whatever

Hi guys, not sure if i'm missing something, but do we have benchmark results comparing DX11 ExpressCard vs TB1 10Gbps?

Potentially have the opportunity to swap out my Elitebook for a late 2011 mbp

Refreshed HP Zbook 15 G2 and 17 G2 have been announced. Availability to be late September.

Both ZBooks have a Thunderbolt 2 port

Both ZBooks support HP Z Turbo drive (PCIe SSD). The 730 MB/s read spec suggests it is at least a x2 2.0 link. Is it NGFF.M2?

ZBook 15 G2 supports a 3200 x 1800 resolution internal LCD

HP ZBook 15 G2: HP ZBook 15 Mobile Workstation | HP® Official Site

HP ZBook 17 G2 :HP ZBook 17 Mobile Workstation | HP® Official Site

Here's hoping the yet-to-be-released zbook 14 g2 has thunderbolt and a quad core option. I didn't see a quad core zbook 14 so chances are slim. One can hope right?

Sadly the performance of a dualcore haswell chip leaves much to be desired

Otherwise looking forward to seeing some second hand zbook 15 g1 on eBay for < $1k

hello.

Found the eVGA quite interesting for CUDA rendering.

I have to spend some 6-8K euros on some rendering farm (2X dualXEON WS's or 4x i7Xtreme DIY rigs) but those will consume space, to much power and time to setup/service + 2/4 slave render Licences + OS.

Can i build a CUDA rendering eGPU for Vray/etc that will be better then the setup proposed. Same money... maybe more? 2 GPU cards, maybe more.... let's say 2 Quadro's k5000. Or some gaming cards. i was aiming for at least 70 CPU threads. (4x six cores slaves+ and one 12core main rig = 36 cores = 72 threads)

Can i beat that?

I'd like to open a new thread but it is impossible.

So: CUDA/GPU rendering on eVGA?

Have you heard of bitcoin mining rigs used for GPU rendering? Would be possible?

If you are wanting a way to put more compute / graphics cards in a Workstation PC, an External setup may be able to help, you could purchase say a Dual xeon workstation which comes with thunderbolt, then on this you could add more cards.

But remember that even workstations don't have unlimited PCI-E bandwidth, this could be a limitation for you.

You could also just install two dual-gpu graphics cards like the Titan-Z

I would still buy from BPlus even at the price premium, correct me if I'm wrong but it seems to me like bplus did all the research and testing on these devices and cooperated with us users and then EXP GDC came in and with a better and cheaper manufacturer.

I know it's not exactly rocket science to build these devices but everyone needs to remember that there are costs associated with all the testing and correspondence they have done.

Sadly, most economies don't operate on good feelings and the cheaper product with the same features will prevail.

In my hopeful opinion BPlus need to somehow get through Intel's lisencing and get a thunderbolt 2 kit and they will again have dominance in this niche market.

Will edit for grammar later.

First of all, I'd like to say a big thank you to Tech Inferno Fan and all the contributors to eGPU community for amassing a wealth of information and experiences.

Secondly my question is about the Maxwell cards that are coming in Q4 this year. I'm looking to buy a GPU with a budget of £200 and right now and the GTX 760 looks like the most attractive option. I'd prefer to get something stronger than the 750 Ti but I'm not sure whether to splash out money for a better GPU when my CPU is relatively old and I have ExpressCard 2.0 speeds(Thinkpad X220, Sandy Bridge i5-2520m).

I don't mind waiting for the new Maxwell cards but would it be of much benefit to do so?

You should wait for maxwell if you can be bothered.The maxwell cards will offer lower power consumption ad lower heat output.

If these factors are not a concern for you, you should probably just get a 760, they are pretty much at the top end of the scale for egpu price / performance.

I'm just guessing but I think the hotplug-ability is to do with the fact that it's now using EFI and the GPT/MBR doesn't make a difference. (But of course can't fully use EFI with MBR)

I'm trying a GPT UEFI installation now

IT WORKED!!

I created a uefi compatible windows 8 installer flash drive

Went into my HP bios and set EFI mode without csm (native mode)

Boot into the win installer and delete all existing partitions on my drive and let windows deal with it.

Now I can come home from uni and hotplug my GPU without having to reboot

Made an interesting discovery today. I was able to get my eGPU working again using Setup 1.30, but it really annoyed me having to use it on boot up. I spent the rest of the day trying to get the eGPU to work without Setup 1.30. What I discovered was that if Windows 8.1 was installed on an MBR driver, I ran into Error 12 and had no hotplug capabilities. Once I installed Win 8.1 on my SSD as GPT, the Error 12 disappeared and I was able to hotplug the GPU. Not sure what this means for eGPU's as a whole, and if this is just a 2570P thing, but it's an interesting observation nonetheless.

Hotplug with pcie 2.0 working?

This may warrant a reinstall for me

Here is my Super simple setup
Consisting of a HP 8470p, EVGA 770SC, PE4l, cheapo junk psu, fan and fan controller.
The case is a Shuttle XPC variant which I stripped down to fit the ATX psu and PE4l in, the 770 was a perfect fit (after removing some rivets  )
Display is a Dell U2713HM 2560x1440 which I picked up for $310 NZD
Temps are great, hovering around 70deg overclocked (+50 core, +300 mem, +.12 vCore) while playing BF4
I recently added the fan due to fears that I was suffocating the cheap PSU since it draws air from the back of the card.

Setup on the 8470p is great, apart from the fact that you have to wait till after POST to plug the Egpu in( or set the delay). I believe this effects 8470p and 2570p
In Win 7 I was able to plug and play W/O setup 1.x but I purchased it anyway,I moved to windows 8.1 and had to use 1.x to overcome memory allocation errors.











I am currently gaming at 2560x1440, getting around 60fps +- good/bad situations online with all medium settings but AA off (don't need so much at higher res)
I made up some benchmarks if people are interested.
These results don't reflect gameplay performance. Games are very playable at 1440
I will take requests for more benchmarks

The unlocked multiplier, like on a i7-3920XM, requires BIOS support to unlock. Furthermore, these HP systems are TDP locked to 45W. I've found that TDP-throttling occurs such that CPUs like a i7-3740QM, i7-3820QM or better often can't even hold their x35 4-core multiplier. The end result of the study being considerable variation in TDP output of Ivy Bridge CPUs. The way I was able to get best performance was to test about 4 i7-3740QM CPUs and cherry pick the best one. You can see my testing results at http://forum.techinferno.com/throttlestop-realtemp-discussion/6958-haswell-step-backwards-ivy-bridge-i-have-some-shocking-tdp-results.html#post95181 .

The OC ME FW unlocks BCLK overclocking capability, allowing an additional 5% BCLK overclock. There you are stretching the system out to get extra performance from the generous VID/TDP overhead Intel adds for stability across many physical environments.

Damn, thought I was onto something major.

Will be going for the QBRP D0 Stepping model then

Thanks for the advice, you da bomb

Hi Guys,

I am running a i7 3632qm in my 8470p and i'm looking to upgrade it to something like a 3740qm or 3820qm, (I play lots of games and lots of VM's)

But I saw an ES 3720qm chip QBC1 on ebay with 8mb L3 and a 'unlocked multiplier', this looks just like a slightly downclocked 3920xm

With the Intel management engine bypass, will I be able to overclock this cpu by increasing the multi? Or am I better off getting a non unlocked version

(Idle(ish) powerconsumption is a concern for me, I need my laptop for many hours at uni using IDEs)

Thanks for your input

This looks very promising.

Think it'll be worth the upgrade $$ over a EC solution?

My current setup is taking a bit of a beating at 1440p

Provided I can get a Zbook 15 at a decent price.

Maybe wait for TB3 which will hopefully come out with broadwell

Oh, @ivan_xiao, I just remembered, the easiest solution for your audio problem is probably just to use a USB Sound Card or a USB DAC (they bypass your internal sound card), That way you don't need to do any PCIe/mPCIe splitting of any sort.

Yes this, pickup a cheap DAC off eBay or wherever for under $10 usd

So i been wanting to get into egpu systems and was wondering if there was any cheaper way of connecting a 780 ti to a notebook than than a Echo Express III-D and Mac book pro retina? Is there any cheaper laptop with thunderbolt 2 and any cheaper way of connecting the 780 ti? I would be ok with building my own enclosure but I would need to know what adapters to buy.

I'm new sorry if I broke any rules.

You could possibly find a cheap HP ZBook15 on eBay

I don't know of any implementations using the zbook so I can't say for sure but if I had the cash, I would go for the zbook 15

TLDR; Want upgrade from 1080 to 1440, is this going to kill performance on my egpu in gaming AAA titles

Hi guys,

I have been running my egpu setup for a while now,

Elitebook 8470p i7 35w and a gtx 770.

I am extremely pleased with performance in all gamessuch as BF4,DayZ and Arma3 at 1920x1080. (Happy to give numbers if anyone wants)

I have been given the opportunity to purchase a dell 27" 1440p display at below wholesale cost and I was wondering if anyone knew what kind of performance loss due to bandwidth I will incur.

I do not mind reducing my graphics settings.

Greetings from Kiwiland

Hi guys, new to the forum.

I'm getting my HP 8470p i5 3210m 2.3 Going with my gtx 560TI @x1.2 960/2030mhz

I seem to be getting terrible frames in Battlefield 4(mid 20s- low 30s) 1680x1050 All low, no AA, and I am starting to think that it might be more of a CPU bound issue

Is this normal for my setup? I have been unable to find a compilation of game performance per E-Gpu
