DIY eGPU experiences

Problem description
1. What's the problem.

After running compaction with the DIY Vidock setup, and chainloading, I get a message stating that the OS is missing.

Spoiler :

Platform Description
1. OS: Windows 7 x64
2. System: Lenovo Y650
3. RAM: 4GB
4. eGPU used:PE4H ver2.0 with EC2C

I had it up and running for a good while and then it just crapped out on me. I want to get it up an running again. Any help would be appreciated thanks.

Please check your HDD partition layout (post screenshot here - "Computer Management" \ Storage \ "Disk Management"). Is there any active partition other than "System Reserved" partition before OS partition?

Hi,

I have a NEC Versa E6500 with GMA graphic accelerator.
I have a GTX 460 with a 620W Seasonic PSU together with a PE4L.

Spoiler :

I installed Verde 270.61 + MikjoA's nvam.inf (32-bit) as in here

I unplug the EC2C, boot my Windows 7, and Sleep my Win7, plug my EC2C into my laptop, then power on the eGPU. Now I can see my graphic card driver as in here:

However, my problem is that the eGPU does not output into my 23" LCD, my 23" LCD is all black. I try to change the display setting, but my LCD is not detected

Please let me know what should I do, I tried many ways but I still stuck.

In addition, when I power on my eGPU, plug my EC2C to my laptop, and boot my Windows 7, I got BSOD (blue screen). Can we fix it?
If we can, I think the problem can be solved, I will always plug my EC2C card to my laptop.

Thanks all your kind helps

Does Nvidia control panel detect the external monitor? I noticed the "Base System Device" have exclamation mark on them. What are those? Also "System devices" tree is expanded. Is there any device with exclamation mark on them in "System devices" tree?

Hi all, I have the 'ExpressCard to PCIe adapter (PE4H)' setup with a 9800 GTX+. I'm getting the 'This device cannot find enough free resources that it can use. (Code 12)' issue in Device Manager. In the troubleshooting page for eGPU, where the fixes are listed, one is to run eGPU Setup 1.x. I've been going over the instructions on how to run eGPU Setup 1.x and I have to admit that I'm very confused - as they seem to be written for people who are familiar with the software. Are there any stright forward instructions that tells you 'step by step' how to run this software in order to fix the Code 12 issue? I've tried booting to the software and looking at some of the menus but I have no idea what I'm doing. Any help would be great. My system is an Acer 8940G, Win 7 64bit, 4 GB ram, with a GTS 250M dedicated gpu.

You just need to run 32-bit PCI compaction. There is simple installation instruction (labelled with "How do I install this software?") in Setup 1.x page. Just three steps. Then reboot & enter Setup 1.x (choose no.2 in Setup 1.x menu). In Setup 1.x screen, choose "PCI compaction" & choose "Run". Follow the on-screen instruction. After finish, choose "chainload mbr". It will bring up Windows / Setup 1.x boot menu. Just choose Windows to boot into windows.

Please post screenshot of the Device Manager (set View to "Resources by connection" & then expand the Memory tree).

Thanks for your reply
No, Nvidia control panel does not detect my external monitor... It is the same as before "I sleep my laptop, plug EC2C, turn on GPU, wake up laptop". Nvidia control panel does not change after I plug my eGPU in.
In "Base System Device" those 2 exclamation marks are not related, I got those long time ago. It does not affect my system, so I leave it there.
In "System devices" there's no more exclamation mark.

I don't really understand Setup 1.x, do I need to do that? What does the "Chain load mrb" do? What does the "setup.bat" will do?
Thanks

It might preventing eGPU from working properly. "Base System Device" sounds like chipset related. When you leave like that, it doesn't get any resources which means eGPU might occupied wrong resources.

Many thanks kizwan
I installed drivers from my NEC computers website. Now those "Base System Device" problems are gone.

I reinstalled graphic driver with
285.62-desktop-win7-winvista-32bit-english-whql.exe

Now I am able to Unplug EC2C, Turn On Laptop, Turn On GPU, Plug in EC2C. The laptop screen gone dark, but nothing appears on the LCD connected to my GPU.
I capture the screen shot when my laptop gone dark, and I see:

My GPU driver is detected, but my LCD screen is still dark

I guess my laptop screen gone dark, it try to route the display to my LCD, but for some issue there is nothing appear on the screen...

Please help...

OK. At least there is some progress. If you can access your computer when the screen go dark via remote desktop or VNC, try open Control Panel to check whether external monitor is detected or not. If detected, try manually setting main display to external monitor. OR try use keyboard hotkey/FN keys to set display output.

Hmm..seems like there is another partition before it, how do I fix this?

Use Setup 1.x to do 32-bit PCI compaction on the eGPU, then chainload to Win7.

I see what you mean, but the problem is that I cannot boot if the eGPU is turned on, but if I booted the device and turn on the eGPU it doesn't recognise even if a hit F5.

I have this exact same issue as Mavericko93 as I also have a ProBook 4525s (albeit with different specs: Athlon II P340, 8GB RAM, integrated Radeon 4250, Windows 7 Pro 64-bit). I'm running a PE4H 2.4+ setup with an HIS Radeon 5770.

Here's what I've done so far:

1) Despite not having my eGPU detected, I still went ahead and did a 32-bit PCI compaction and chainloaded to Win7. The result was a blank screen.

2) I then tried the 32-bitA compaction, followed by a Win7 chainload. The result was that it booted into Windows 7 normally, notified me that an AMD High Def audio device was successfully installed. I then looked in Device Mangaer under Display Adapters and it shows the 4250 working properly and a Code 10 for the VGA Compatible Device (i.e the 5770). I then realized that I only had the drivers for the 4250 installed and not for the 5770 so I downloaded those as well. Upon restart (via startup.bat & eventually through another 32-bitA compaction), it again boots into Windows normally but this time the 5770 doesn't show up under Device Manager (not even as a VGA Compatible Device).

3) I then tried the 36-bit compaction and the only sub-option it gave me was for the dGPU. Upon chainload, Windows booted normally but with low resolution graphics.

I even tried to tinker with manually allocating resources via the 'iport bridge' command, but I have no idea how to find and figure out the correct value to put in.

Any guidance would be awesome

Look alright to me. It works before, right? Does it suddenly stopped working OR you reinstall windows & it doesn't work anymore?

EDIT: Actually, the partition layout is a bit odd; primary - logical - primary. Did you create new partition?

Yep it worked before but after not using it for a month it stopped working after decided to use it again. Maybe an update problem?

[kizwan]

While you stop using eGPU, did you create new partition or change the partition layout? I'm assuming GRUB chainload to the 3rd partition (OEM partition) which might explain why you got "missing operating system". Try to make the partition layout as simple as possible. You might need to delete "OEM partition". As always do backup first.
