eGPU: attempting NVidia Geforce GTX 760 with L502x XPS

Recommended Posts

Hi, I am new here but I have been reading the forums for a while. I have just got up the nerve to do my own eGPU. I am very confused about some things. I will ask them to clarify them even though I have read through the forums. I just cant seem to pin down with confidence that I know what I need to know. So here goes. My system is: Dell XPS L502x 1080p monitor 8gb Ram, 1TB HDD, Bluray Drive HDMI, mPCIe slot (which I think houses my intel wireless a/n/g/a/b dual band card), and mini-display port and 2- USB 3.0 ports, Card reader Nvidia Geforce 525m discrete gpu with intel hd3000 integrated gpu Intel i7 2670 qm 2.2 up to 3.1 ghz quad core processor

--So here is my question: I have a gtx760 gpu to use for the egpu I will be ordering this to adapt the mpcie









PE4L V2.1b + PE4L-PM060A



and I have a 520 watt insignia pc power supply to power it.

Now will these components work with my set up? Is this everything I need? I really do not know what I am doing here but I do everything myself so Im determined to do this as well. I think with the help of the genius minds I have been following on this forum I can do this. You people are very smart and helpful. Please let me know if I am totally off base with this set up. Thanks!

daver160 has a lot more detail on doing a NVidia eGPU implementation on a Dell L502x at http://forum.techinferno.com/diy-e-gpu-projects/2824-%5Bguide%5D-dell-xps-15-l502x-gtx650ti%40x1-1opt-pe4h-pm3n.html#post38573 . That guide made sometime ago when PE4H 2.4 was the more prevalent adapter with the PE4L V2.1b only coming into the picture.

There are more choices today. You can use any of these Gen2-capable adapters: PE4C-PM100C V2.x, PE4L-PM060A 2.1b or EXP GDC V6.0 mPCIe kit.

The recommended adapter is the newest PE4C-PM100C V2.x because it has CLKRUN delay switch and a 220W PSU supplied that the others don't. CLKRUN is often need for mPCIe eGPU implementations. The 220W adapter enough to power your GTX760 and eliminate the need for a 520W Insignia power supply. It also uses a handy socketted mPCIe cable that only the EXP GDC V6 provides.

NOTE: EXP GDC V6 doesn't supply a Dell 220W DA-2 adapter if you buy via Aliexpress. To get it as part of the package you need to buy it via one of the Chinese forwarders OR buy it separately.

Thanks for the quick response. I appreciate it greatly. I already have the 520 watt insignia adapter and pe4l already purchased. Will it work just as good as the pe4c? Will I need to get the CLKRUN delay switch with that pe4l as well? Does it seem I am good to go here?

Yes, Pe4L 2.1b can run a Gen2 link. The CLKRUN issue can be worked around by hot plugging the mPCIe (wifi slot) end with the eGPU powered on if affected. So you're good to go as is.

I was successful with my eGPU. I Do not know how but I was. I did not even use the setup 1.x that i purchased. All I did was set up the eGPU to Pe4L, I set up floppy drive connector from PSU to pe4l, I connected six pin power adapters to my GTX 760 GPU from the PSU, I shorted out the motherboard connector from PSU by connecting a random wire from the green wire connector to the black (ground) wire connector. I inserted the pe4l cable mpcie connector into the WWAN/TV slot next to my wireless card adapter, I plugged in the PSU and turned on my Computer. I kept the PSU power turned off at first. I logged in to windows and uninstalled the ALL Nvidia drivers, plus I deleted thr NVIDIA Corp folder in Program files, I restarted computer. I kept the PSU turned off. Once I was logged in to windows I put the computer to SLEEP mode. I powered on eGPU PSU, I logged back in to windows once I saw fan spin on EGPU, I checked device manager to ensure eGPU was recognized under display adapters. At first it was not recognized but only some generic display adapter of some sort was there(i forgot exact name it said-but it was different than the other two<525m and hd3000>), I inserted NVIDA disc that came with eGPU gtx 760, I installed the drivers from the disc, Then I shutdown computer, I powered PSU OFF, then I turned computer back on and logged into windows. I went back to sleep mode and powered on eGPU, I logged back in to windows and ensure that device manager now displayed the gtx 760, Then I updated drivers manually on NVIDIAs website for latest driver because not latest drivers were not installed automatically. Then I plugged HDMI from eGPU 760 to external monitor, I went to computer settings and selected to go to change pc settings, then I went to pc & devices. then I selected display, then I selected to display from monitor number two and make that my main display. I was then broadcasting from the external monitor only. I then went into device manager and disabled my other nvidia gpu (525m). I went to nvidia control panel to ensure the settings could be pulled up for the gtx 760 and everything was there. The whole time I never had to run the setup 1.x sO threw that $25 down the drain. But I am just happy and grateful for the help I received from NANDO and others in helping to get setup. I will post my 3dmark results:

FIRESTRIKE:

nvidia 525m: 848

eGPU NVidia GTX 760: 4500(ish)

SKYDIVER:

525m: 2500(ish)

eGPU 760: 11900(ish)

Would advise doing a 3dmark6 run with your rig as it is now. Then re-boot via Setup 1.30, disable the dGPU and set your port that hosts your wifi/eGPU to Gen2. Then re-run your 3dmark06 bench to see the different results which I anticipate will be markedly better. Also note that you'll have an accelerated eGPU internal LCD mode when you do this.

How do I reset my port to GEN 2? My thing with the setup 1.x is that I have no way to run the thing. It can never detect my eGPU. I hit f5 to rescan but nothing. I cant my egpu to turn on unless I boot past the diy setup screen into windows and then put windows to sleep. I cant boot up egpu before booting computer up because I just get black screen that way

Booting with wifi, then powering on and hotplugging the mPCIe connector in place of wifi should see the eGPU detected. Nevertheless, with the wifi in place you'll be able to see which port is the one to set to Gen2 speed. Then do:

PCIe ports->Gen2 switches the port to Gen2.

Video cards->dGPU[off] switches off the dGPU. Necessary to x1 pci-e compression and accelerated internal LCD mode.

Worth testing to see if the system maintains those settings after your current sleep-resume method.

Use GPU-Z to confirm the eGPU is running at Gen2 speed (x1 2.0) when placed under load.

i just am not sure what booting with wifi means--do you mean safe mode with networking? I am not super literate about computer terms

- - - Updated - - -

i downloaded the program you speak of. It says BUS INTERFACE: PCI-E 2,0 x 16 @x1 2.0 while running test --what does that mean?

also, i noticed i cannot get nvidia control panel to come up unless egpu is projecting to external monitor. when i try to use intenral lcd im told there is no nvidia card connected to a monitor. so idk

dGPU must be disabled for Optimus to work using the eGPU. Use the Video cards->dGPU[off] function in Setup 1.30 to do that.

do i run compression on egpu or dgpu or all except the sata-usb-sound,etc.?

Are you getting an error 12 against the eGPU in Device Manager? If yes, then highlight PCI Compaction->Run compact, hit F1 and review the over 20 different PCI compaction parameters to try to overcome error 12 and avoid BSOD/freeze on Windows startup after chainloading.

it was working good. i tried to run the egpu setup 1.3 to do what tyou said but now when i cut on egpu i blue screen and reboot after a few minutes. i havent run any compaction yet

If the eGPU works then fails after a few minutes of use then the problem is to due to eGPU adapter/comms stability. A BSOD will happen if there is insufficient power during peak load or the eGPU adapter/cable combo cannot run a Gen2 link reliably. The latter can be tested by switching the port to Gen1. The former by using a more powerful PSU or using two PSUs - one to drive the PCIe slot and first 6 pin PCIe power. A second one to drive addition 6/8 pin PCIe power

I found out that the BSOD is only occuring when I open z-gpu --- maybe its problem with that program and not eGPU

      I have tried to update nvidia drivers of my notebook ge72vr6rf apache pro. The only drivers that works are the ones provided by the msi. The problem is that they haven't updated those since 2016 and I can't play newer games. 
       
      Some say you need to mod your 1060 drivers, which I have no idea how to some says you need to update the flags in ini files. So please help me
       
      Thanks for your time.

      Hello, I've got a Quadro M2200 (GPU: GM206GL-A Revision A1, and MxM 3.0a Maxwell card) with the following bios: 84.06.76.00.1C
       
      I've read that this card is very similar to the GTX 965m, but that it has been underclocked considerably. It seems to be a good candidate for unlocking since I hardly see the temperature exceed 70C as-is. I'm requesting help with this - I'm not sure if it's possible to simply flash the vbios from a Dell GTX 965m (MxM 3.0a) or if some type of edit of the card's current vbios would do the trick. I'm hoping someone could help me out with the specifics of doing such an edit if that's the case. 
       
      Thanks!

      Following the release of NVIDIAs new 436.02 driver which I mentioned in an earlier article here, I've decided to make a quick and dirty video showing off NVIDIAs new Sharpen filter which is part of their Game Filter feature. It works with the most popular APIs including DX 9, 11, 12 and Vulkan and can be set on a per-game basis with granular settings of 0-100 unlike AMDs RIS which is limited to Navi and lacks DX 11 support.

      Hello!
       
      I have recently acquired my Dell Inspiron 15 7000, and I am interested in building an egpu setup for it. It has a USB-C port. Any recommendations/guides out there?
       
      thanks.
