DIY eGPU experiences

[kizwan]

One notebook have ExpressCard slot while another don't. So, you can connect eGPU to ExpressCard on the first rig & for the second rig, you'll need to use mPCIe port. Unless you can do x2 link setup (using two PCIe ports), you will not get fun. You'll experience stuttering & lagging while playing games. Since, your notebooks doesn't have any of the iGPU (Intel GMA 4500MHD or Intel HD Graphics or Intel HD 3000), you also can't do x1.Opt setup. You also did mention that you don't want to use external monitor. x1.Opt setup is needed if you want to get eGPU acceleration on internal LCD. As I mention earlier, without x1.Opt setup, you can only run games on windowed mode on internal LCD (if want to use eGPU processing power) & you still need external monitor.

Unplugin & plugin x2 link setup eGPU also not fun.

first post and im having some problems, but i'll try to be as detailed as I can.

Problem description
1. Laptop doesn't seem to recognize the egpu, and when I boot with it on My laptop doesn't boot and just sits on a black screen until i turn off the PSU to the GPU
2. I checked the FAQs and they stated to try and hotplug the eGPU while your in standyby. that does not work for me. the laptop doesn't boot when i attempt that but once i switch off the PSU it will boot

Platform Description
1. windows 7 ultimate, 64bit
2. toshiba satellite l655-s5071, intel HD graphics, series 5 chipset (IIRC)
3. 4gb ddr3 (have tried removing 1 stick and running 2gb as well with not change in results)
4. gtx550 ti

from what i know the card needs a 116w, my PSU is 300w total with single rail. 12v+ max current of 16A meaning it gives out 192w. If im doing the correctly)

also im running this via mPCIe in the location that my old wireless adapter is. (only one available on the board)

i have the HIT express card adapter ver 2.4a and the mpci adapter and psu switch they supply.

i have also tried to install the verde drivers (with modded INF file) as im planning on doing this as an internal LCD setup. but when i run the setup it says that it can't find a compatible device.

any assistance you could give would be great

any assistance you could give would be great

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.

I have not found the thickness of the PCB of both PE4H and PE4L on HWTools schematics, can anyone tell me how thick is it? I'm making a 3D model in sketchup for the whole setup, but i need to have the exact thickness without any connector.

Thanks in advance

Hello, i'm french guy, i have a Dell E6420 and i'm interesting by eGPU system, and i would like to know if it's possible to work with my Dell.

E6420
Bios A07
i7 2620qm
6Go Ram (8go soon)
250Go HDD (120Go ssd soon)
NVIDIA NVS4200M

Hi Guys. I have X220T, GTX 560, p4EH, but can't launch any game, and connect extLCD, because Nvidia mod. 285.62 + kallitokaco's nvam.inf driver falls without errors. Below some screnshots.
As i understand my card work with PCIE 2.0x (1.2Opt), because i install setup 1.x. I booted with working p4EH and videocard. I have not any idea thats wrong with it.

Hello french guy,

According to Review Dell Latitude E6420 Notebook - Notebookcheck.net Reviews , your notebook have ExpressCard slot & Intel HD 3000. So, you can use eGPU on this notebook. You can do x1.Opt setup with Nvidia Fermi desktop graphic card. Opt=Optimus provide PCIe data compression which boost performance over PCIe x1 link. You might want to wait for PCIe 2.0 compliant kit from BPlus/HWTools. With PCIe 2.0 compliant kit you can get more performance because eGPU will be able to operate at 5Gb/s speed at each direction.

Spoiler :

Hi,

What is the PSU specification? What is the max current at +12V?

ok thank you, have you a link for PCIe 2.0 compliant kit ??

[kizwan]

The PCIe 2.0 compliant kit not available yet. If they available later, it will be announced at first post of this thread (or here for PCIe 2.0 kit update). They might be available this January/February.
