DIY eGPU experiences

[User Retired 2]

I don't want to buy setup 1.x because if it don't work i'll loose 25 USD more ...

Setup 1.1x can certainly disable the NVS4200M dGPU, plus there is a NBR user coupon that makes it a $15 donation to access.

Hello Nando4, thank you for looking into this...

PM sent.

"a little" update of results after clean instalation and without nvam.

Can you please create one definitive HP 8460P+GTX560Ti@x1.2Opt post with all the details so I can link it? ie: system, RAM, any special requirements to get it going; eGPU hardware, drivers, benchmarks. You have the details already but it's across around three separate posts. Thanks.

I'm excited to jump in to the world of egpu, and am expecting it to go pretty smooth.

I have a Lenovo T520, with latest 1.36 bios (should fix whatever TOLUD issues previous bios's had)

The machine has a i7 2860qm cpu, 16gb of mem, and intel 3000 + NVS4200 dgpu.

I bought a PE4L 2.1b, and a gtx560. hoping to get x1.2opt performance via external display. And will be using a 203w/16a modded xbox 360 psu to power the gpu.

Since the lenovo T520 supports pcie 2.0 x1, and had fixed the TOLUD issues in bios, I am expecting a pretty much plug an play operation.

Am I correct? or due to have the 16gb of ram, will I need to do a DSDT override? to get into 36bit allocations.

Also wondering if there will be a need to disable the dgpu? to get the egpu to optimus with the intel 3000. I disable the nvs4200 in bios if needed.

I can't see a need for the Setup1.x disk in my configuration, but I dont know if I am overlooking something.

thanks

Is there a tutorial somewhere in regards to using an xbox 360 psu as a power source for egpus?

except instead of even bothering with the molex, I'm gonna wire the 2 6pin and the floppy cable directly with no adaptors. I am also gonna put a switch between the +5VSB and the PWR ENABLE Pins. (http://www.instructables.com/id/XBOX...fo-The-Pinout/) So I can turn off,on psu at will

Fabi3n is having a problem getting his Dell E6520's iGPU+dGPU (NVS4200M) + GTX560 working in harmony together, but Joss27's Dell E6420 with same iGPU+dGPU had no such problem.

Since there is no bios option on a E6520 to disable the dGPU, Setup 1.1x can do it. Though Fabi3n is seeking solutions to avoid the $15 donation to access it. I am curious to see how he will solve this problem.

If your T520 has a dGPU disabling bios option then no such problem for you plus I believe that the latest T520 bios does lower TOLUD upon detecting a eGPU so there are no 32-bit pci-e config space issues.

A XBOX360 203W PSU with a 12V/16.5A (198W) rail pairs nicely with a GTX560. It even has enough juice to power a 195W TDP GTX680. Please do post the final pics of your wiring.

Does HIT sell PE4L v2.1? The one that doesn't require any rework by the consumer. I'm only finding v1.5 on their page.

Don't believe HIT sells PE4L 2.1 as yet. I've emailed HIT asking a reply to your question.

PM the HITRC NBR and for good measure drop an email to email HIT for the coupon code.

OK, i've edited my last message during you answered

I really hope that setup 1.x will help me.
