DIY eGPU experiences

I think problem with drivers because on Desktop this card+power supply work perfectly. Please read my last post with question about steps. May be i lost something?

Need to set Gen1 link speed if using current PE4L/PE4H

Your X220T needs to set Gen1 link speed on the port using either Setup 1.x or in the bios if using current PE4L 1.5 or PE4H 2.4 or lower. If not then you'll get NVidia driver BSODs/errors/black screens. PE4H 3.0 will allow Gen2 speed and is scheduled for release in Jan 2012.

See my DIY eGPU implementation: i5-2540M 2.6 12.5" HP 2560P + NVidia GTX560Ti @x1.2Opt for an example.

Hello guys,

I have a Acer 5742G, i5-460M, geforce gt 420m, 4gb ddr3 (AS5742G-5464G64Mnkk | Product Model)

I'm considering eGPU so i can play SW:TOR with good framerate.

How can i do it?
What card do you think it's better for me to get?

I'm a complete noob, never tried something like this.

Thanks in advance.

Hello,

Aspire 5742G doesn't have ExpressCard slot & only have one mPCIe port which currently use by WLAN card. So, the only way you can use eGPU is by using the mPCIe port. You will not be able to use WLAN when using eGPU. Aspire 5742G is Nvidia Optimus notebook which mean it have Intel HD Graphics enabled. (Correct me if I'm wrong.) You can do x1.Opt eGPU setup with Nvidia Fermi desktop graphic card. Opt=Optimus provide PCIe data compression which boost performance over PCIe x1 link. This also means you can get acceleration on internal LCD.

Use Setup 1.x to confirm your GTX550Ti gets detected and/or apply mPCIe anti-whitelisting. Also test the PCI Reset Delay switch on the PE4H and CLKRUN switch on PM3N to help you along as well.

ok so i tried this, Idk what exaclty im doing wrong but I get the bootmenu option for the setup1.0f when i select it it boot loops back and gives me the options again. i used the faq's but im getting alittle lost. i also tried to hotplug the egpu set-up with the win7 sleep method but as soon as i attempt to resume the laptop craps out and won't boot again until i turn the setup off. any suggestions?

Set PCI Reset Delay switch on the PE4H and CLKRUN switch on PM3N. OR at Windows/Setup 1.x boot menu, connect eGPU & then boot into windows.

I set them at 16seconds and turn it on at the windows/setup 1.x boot menu and it will boot to windows but it doesn't detect the eGPU. i believe it is because i need to whitelist the egpu in setup 1.x but it will not allow me to boot to that POST. or am I assuming wrong to think it will boot into a POST when i select setup 1.x at the boot menu?

[kizwan]

There is "OR" in the statement. There are two ways:-

• Set PCI Reset Delay switch on the PE4H and CLKRUN switch on PM3N
• connect eGPU to notebook
• power ON eGPU & notebook
• boot into windows.

OR

• Power ON notebook.
• At Windows boot menu, connect eGPU to notebook
• Resume boot into windows.

I believe PCI Reset Delay set to 7s is more than enough.

Sorry, but i can't instal this setup 1.x properly.
1)I started RMPrepUSB, made usb bootable flash as writen

but this RMPrepUSB trying to download all 200gb files from C:/ not only bootable 5 files. It's make free V:/ usb disk.

2)I make directrory C/IYViDock with files

3) Run diyvidock-mount.bat, but can.t create boot disk because have an Error: Disk V not imDisk device.

It's too much problems to run setup 1x in DOS, but in win7 this bat files don't work. Explain please, how i can install this without so much steps and errors? Anybody can write a youtube video to make boot disk and running DOS and making neccesary permissions for 1.2x? It's to dificult to me trying makes so steps with unthinkable errors.

Start by downloading DIYeGPU-Setup-10f-pre28 here rather than the 1.0e you are using.

Ok. Installed setup 1.x

1) Change port link to 5Gb
2) Perform 32bit compaction
3) Run config.bat
4) reboot
5) driver nvidia fals with error and recovery
6) CRT cant connected, driver fals. if i run any game i see BSOD.

Thats the problem with driver? 1.2x 5GB connected, power suffcient 60A 12v, lastest mod driver installed.

May be i must boot without Egpu, and in win connect expresscard? But driver still fals(

I saw once more problem:
1) if i use 1.0x i see driver properties.
2) if i swithed to 1.2x i can see driver properties as chose monitor\3d\Physix and ecs.

[QUOTE=kizwan;8167143]Hi,

Please post PSU specification. What is the max current on the +12V? Did you connect both 6-pin PCIe power connectors to ATI HD6870? The two 6-pin PCIe power connectors on the ATI HD6870 are not optional. You need to connect both.

BTW, instruction on how to obtain screenshot is well explained in Setup 1.x page, under "5. How do I access my diagnostic dumps or screenshots?".
Hi
I bought a new PSU with this config

I changed my eGPU to "ASUS EAH5750"
but still have the same problem

eGPU not detected
eGpu is working silently
Two green LEDs are ON

I turned the PSU off and set to 7 sec, turn off the laptop and boot into setup.
but the result was the same.
unplug & replug & ...

the eGPU is not listed in widows too
I want to mention that my kit worked with 7300 gt despite the error 12.
here is hardware setup if it can help:



pls help me!
