  1. just an update for reference: 1. poor CUDA-Z memcopy speeds: PE4L cabling can be an issue! I discovered the PE4L cable orientation and twisting can cause the PCIe 2.0 x1 link to drop down to PCIe 1.0 speeds depending on how the cable from my expresscard slot is routed to the PE4L (minimize bends in cable if possible!). Now I am back up to expected PCIe 2.0 x1 link speeds (getting ~375MB/s memcopy speeds host-device and device-host in CUDA-Z). Keep the link cable as straight as possible! 2. eGPU crashing: one challenging problem to solve, my eGPU GTX 760 kept crashing when running games like Shadow of Mordor, with no discernable pattern as to why. At first I figured it was driver/windows issues, since my old GTX 560 didn't have any issues with these games. I eventually discovered that my 500w PSU wasn't fully powering my GTX 760 (170w TDP)! My psu is generic brand listed as able to provide 240w from the 12v rails. I have been using a 2x molex to 1x 6-pin PCIe power cable connector since my PSU only came with 1x 6-pin PCIe power plug and the GPU needed 2x 6-pin. Turns out that you need to power BOTH molex plugs in order to run full 2x 12v to the 6-pin PCIe (there are two 12v input lines with the 6-pin). Crashing has resolved once I fully powered the GTX 760. Just a reminder to ensure your GPU is fully and properly powered if you are getting crashes under load.
  2. Yep, same laptop same Win 8.1, just swapped in the 760 for the 560. I did a full set of 3DM'11/vantage/06 and Unigine valley, reboot with other card and repeat. I've got both cards on hand and have been re-testing past day or so. I agree, 3Dmark'06 can be quite variable upto ~5-10%, but here I see 20-35% LOSS in performance going from GTX 560 to GTX 760, but only in internal LCD mode! I mean at the very least the GTX 760 should be equal or better than the GTX 560 right? it certainly matches expectations of improved performance but only via external LCD output. GTX 560 internal: 3DM'06: sm2.7415 sm3.7445 (score 17901) Unigine Valley DX11: 2118 (avg fps 50.6) GTX 760 internal: sm2.5389 sm3.4299 (score 12477) Unigine Valley DX11: 1766 (avg fps 42.2) My GTX 760 has this strange fluctuating mem copy rate in CUDA-z, every half second (the refresh rate of cuda-z) the device to host mem copy jumps between ~360Mb down to ~250mb, while GPU utilization also spikes from 0 to 99%. My old GTX 560 was stable at 400Mb for device to host mem copy.

    Setup 1.30 Discussion

    Hi all, just wondering if anyone else encountered a similar problem: eGPU system: Dell vostro 3560 i7-3632QM (iGPU HD4000) + Radeon 7670 dGPU (disabled via setup 1.15) 12G ram Win 8.1 PE4L 2.1b expresscard GTX 560 (gigabyte) OC to gpu 950/ ram 1150 Bench graphics scores (internal / external) 3Dmark11: 3887 / 4124 Vantage: 14612 / 16506 3Dmark'06: sm2.7415 sm3.7445 (score 17901) / sm2.8601 sm3.10468 (score 21883) Unigine Valley DX11: 2118 (avg fps 50.6) / 2323 (avg fps 55.5) Cuda-z mem copy: host to device: 380Mb device to host: 400Mb So I upgraded from my old GTX 560 to a newer GTX 760 Zotac amp edition, but it seems like my internal scores have actually dropped, and I can't seem to figure out why! My temps are good ~60c never reaches throttling. External bench scores are great, in line with other reported results.

I am certain my iGPU HD4000 is not doing the internal rendering, since I would only manage something like 5fps in Unigine valley with iGPU. I've already tried doing clean nvidia driver install (with DDU). Also, nothing else in system has changed (the gtx760 was straight swap with the gtx560). Anyone experience similar issues with poor performance driving internal LCD when upgrading from older Nvidia cards? very strange.

Also, nothing else in system has changed (the gtx760 was straight swap with the gtx560). I'm fairly certain PSU isn't likely culprit since the external benching was stable and did not hit thermal limits.

    Do you mean wire the 360 psu such that you can switch it on using the SWEX?
  6. tondy

    eGPU experiences [version 2.0]

    SWEX / ATX plug is only for switching on the ATX PSU. You'll need the 6-pin to fully power the GPU. You can always hack 6-pins onto the 12v rails if connectivity is a problem.

    TH05 Recall Notice

    I hope they'll sell the TH04 in the same format as the new PE4H 3.2; eg. choice of full kit or components alone.
  8. Thanks Nando! I'll give your suggestion a try. I am testing if I can boot with the HD6870 now that I have setup 1.x. Will let you know the bench scores when I finish downloading them!
  9. Update - everything up and running! Recap: eGPU (AMD 6870) detected but driver conflict with dGPU (AMD 7670M) = ATI catalyst drivers would never recognize the eGPU (tried all types of drivers including stock Dell, desktop AMD catalyst, modded Leshcat drivers). 1. Bought used GTX 560: able to avoid driver conflict, was able to get all three iGPU + dGPU (AMD) + eGPU (Nvidia) recognized and running! However eGPU (GTX 560) could not activate optimus and only able to output to external monitor. 2. Setup 1.x disabled dGPU causes iGPU + dGPU (HD 4000 + 7670M) 'custom driver' fails to load, windows falls back on default VGA + GTX 560; no optimus. 3. Setup 1.x disable dGPU + remove the vender custom iGPU/dGPU driver + installed latest intel HD 4000 drivers = success! optimus working and outputs to internal LCD transparently. Quick bench results: GPUz: PCI x1 2.0 link CUDAz bandwidth: ~380Mb both ways (76% of theoretical max pci x1 @ 2.0) 3Dm6 (int/ext): 16386 / 18139 3Dm11 (int/ext): 3737 / 3843 Remaining issues: Is it possible to load multiple video drivers in Windows in parallel? eg. have two sets of drivers, Set A = stock intel HD 4000 (works with optimus), and second Set B = Dell vendor supplied iGPU + dGPU driver? Right now if I want to use the eGPU I must have the stock intel HD4000 driver installed (which does not work with the 7670M dGPU), however if I install the vendor drivers for the switchable 7670M then the Nvidia eGPU can't hook into the HD4000 to do optimus/internal LCD. I will also do the xbox 203w PSU project to maximize compact portability Summary of final working config: Dell Vostro 3560 (late 2012): i7-3632QM (H77) + AMD 7670M dGPU / 10Gb ram (8+2) / 128G SSD +32G mSata +750G HDD (ODD caddy) / FHD 1920x1080 LCD / Windows 8 Pro x64 (MBR partition). eGPU kit: Gigabyte GTX 560 'OC' / PE4L 2.1b / 450w ATX PSU / DIY-eGPU-setup-110b5 (disable dGPU only, PCI compaction unnecessary). Misc. Note: UEFI was a pain to work with, I will echo the advice of sticking with MBR if running x86 laptop with windows 8.

    I would personally try disabling dGPU via setup 1.x before flashing bios. You can run setup 1.x via usb for temporary testing until you've settled on a working setup. Since you bought the PE4H from HIT you should be getting setup 1.x for free included.

    That's a great idea, it would certainly streamline the most up to date information and also allow all of us to contribute our bits and pieces.
  13. Hello all, I'd like to start a thread detailing my experience with getting an eGPU setup on a relatively budget Dell laptop. I am amazed at the progress created by this community. My work has required me to travel for the next year, so I have decided to take the plunge and transition from a desktop to mobile work/game space. Dell Vostro 3560 (base specs): i7-3632QM, Ivy bridge H77 Radeon 7670M dGPU 1920x1080 15.7" 6Gb ram (4+2), 32Gb mSata/750Gb hdd 1x Expresscard 2.0 3Dmark6 HD4000 / 7670M (6197 / 8486) I have swapped ODD with 128Gb SSD, and will be upgrading ram to 16Gb later. eGPU: gigabyte radeon 6870 OC update: used GTX560Ti and GTX760 later on 450w psu PE4L 2.1b DIY eGPU Setup 1.30 software Setup: Default Win 7/8 pci bus TOLUD: 9FA00000 (2.5Gb) (w/ both intel HD 4000 and radeon 7670M enabled). I figured should have no problem with "error 12". 1. Starting from fresh win 8 install (MBR, not UEFI/GPT) using default WDDM drivers: hotplugging the eGPU triggers new detecting device from device manager, eGPU gets seen and resources apparently allocated (256 + 128 mb of pci bus space). However I cannot get monitor (plugged into eGPU) detected. 2. With eGPU still plugged in, rebooting causes both the dGPU and eGPU to be inactivated with Code 43, but I can boot into desktop (via iGPU I presume). 3. Installing latest Dell drivers (AMD + Intel) I can get catalyst/switchable graphics function of the dGPU working, but will get BSOD/crash when hotplugging eGPU. I also get BSOD/crash on boot when eGPU installed (windows boots but can't get to desktop). 4. exactly same situation with win 7. Well at least it only takes 10s to boot to desktop... I suspect this is most likely due to video driver issue? Perhaps using Setup 1.x to disable the dGPU might work (have not tried since I don't have the setup 1.x program yet). Dell bios does not have any options for disabling the dGPU. Q's: A. Does Setup 1.x support disabling dGPU for the newest ivy bridge/series 7 chipsets? I've read how series 5+ chipsets are locked? B. Has anyone had success getting any type of eGPU to work in similar radeon dGPU + ivy bridge laptops? C. Would using an Nvidia card bypass the driver issue? D. Ultimately I am aiming for an internal LCD setup, would Nvidia Optimus perform better on an expresscard pcie x1 @ 2.0 vs AMD 6800 + lucid virtu? I will update as this project progresses, and will include bench results when I can. I'm very grateful for any advice the community can offer, thank you! -T Performance results GTX 760 Zotac Amp stock (boost gpu 1176/ ram 1552) Bench graphics scores (internal / external) 3Dmark11: 5602 / 7183 Vantage: 12381 / 24752 3Dmark'06: sm2.5389 sm3.4299 (score 12477) / sm2.8451 sm3.11304 (score 22447) Unigine Valley DX11: 1766 (avg fps 42.2) / 2940 (avg fps 70.3)

    eGPU experiences [version 2.0]

    Hello, Newbie here, I'm trying my hand at building an eGPU HD6870 setup for my Dell Vostro 3560 (i7-3632 + 7670m, H77, pcie x1 2.0 expresscard). Currently using PE4L 2.1b and 450w PSU; the 6870 takes 2x 6-pin. I've run into something peculiar: simply powering the PE4L + 6870 via floppy & 6-pins I can only get the fans to spin up maybe 1/10 attempts. Connecting to laptop before starting the card also does not improve this. Could this is insufficient power? how would I be able to check? I was reading the faqs which suggested adding the 5v USB input, but would this risk frying the PE4L or the HD6870 by doubling the input with 3.3v? (note: HD6870 and PSU pulled from working desktop so I am not suspecting these to be the cause) On the rare occasion that I manage to get the card fans to spin up, the PE4L and card are recognized in Windows (have tried Win7 and Win8) automagically. However I quickly get BSOD error (atikmdag.sys/atikmpag.sys errors) once the card is recognized, but I suspect this is driver issue more than anything else. Would be great to hear if anyone else experienced similar issues and if you managed to solve it! eGPU power issue resolved: my psu needed time to warm up before being able to power the 6870, I was able to consistently get it to 'boot' (eg. full fan speed) by setting the PE4L switch SW1 to 2 (delay 500ms). My Dell Vostro 3560 has TOLUD of 9FA00000 (2.5GB) and Win8 detects my eGPU (it gets 256mb + 128mb allocated), however I cannot get it to work with my existing dGPU (radeon 7670M) - always get "error 43" and BSOD from atikmdag.sys conflict. Looks like I'll have to buy setup 1.x and try disable the dGPU. Q: does setup 1.x support disabling dGPU on newest H77 (Ivy bridge series-7?) chipsets?
