DIY eGPU experiences

What you're looking for is technical support & the best place to get that is by contacting Villagetronic support personnel. Why you pay so much money on the product but don't want to exercise your right to get after sale support from them?

ok, i will try.
it doesn't matter but i didn't buy vidock directly from them but from ebay as a great bargain (half price). i wrote post here because i am aware that you are more involved in this topic

We are, indeed. But considering your specific problem (with a piece of hardware that's comparable but not the same of PE4L/PE4H) it could be also a problem in negotiation the bandwidth between your EC slot and the ViDock kit (that's why on different notebook the problem doesn't appear) and that's why we suggest you to ask them directly

you're right i wondering if to sell vidock and buy PE4H (if i already got GPU, external screens). one more question: when verde drivers are already installed, and i try to copy nvam, there is no option to overwrite but only to copy. the same situation i had with vostro. is it ok ?

Yes the *.inf files can have different names (based on manufacturers versions and nvidia's will). The install package should check by its own all the *.inf inside the driver folder, so as long as your card is recognized at the end of the installation process, there are no problems even if the modded *.inf doesn't "overwrite" the original *.inf inside the folder)

i wrote to vidock support. but i can see a diffrence between vostro and latitude. with vostro, hotplug works fine with sleep+plug+wakeup order, the same order with latitude ends with restart (with nvidia working on external display).

Don't worry, I'm sure they will be able to give you technical support/advice at least.

You can check whether Gen2 is disabled or not using RW-Everything. The register you're looking for is "LCAP—Link Capabilities Register" (Address Offset: 4Ch–4Fh). It is "D28:F0/F1/F2/F3/F4/F5/F6/F7" where:-

Function	PCIe Root Port #
D28:F0	1
D28:F1	2
D28:F2	3
D28:F3	4
D28:F4	5
D28:F5	6
D28:F6	7
D28:F7	8

* D28:F0 = Device 28, Function 0 (the number is in decimal. RW-Everything use hexadecimal)

For example, if the ExpressCard is PCIe port #4, then in RW-Everything > PCI Devices > Bus 00, Device 1C, Function 03. Look for value at offset 4Ch - 4Fh.

Example:-

e.g. 11 4C 11 04 = 0x04114C11 = 100000100010100110000010001b

bit 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00
     0  0  0  0  0  1  0  0  0  0  0  1  0  0  0  1  0  1  0  0  1  1  0  0  0  0  0  1  0  0  0  1

If Gen2 is disabled at ExpressCard, the bit 0 to 3 is 0001b which explain why your ViDock work at "x1 1.0" (reported by GPU-Z).

wow. thanks a lot. RW-Everything downloaded, i can see all this stuff but i'm not able to recognize where is a adress of my expresscard

[kizwan]

Use AIDA64 to know PCIe port number for ExpressCard. When you know the port number, then refer to my previous post.

PM sent requesting manually check installation details as shown here.

Found the solution. I used Total Commander to execute the program, and that was the problem. I tried running it in plain vanilla Windows explorer, and it found bcdedit no problem.

This is interesting because even if I use "run with admin mode" with UAC off, if I execute the setup-disk-image.bat inside TOtal Commander, it doesn't find bcdedit. This is the first time, this happened to me while using Total Commander. I guess something in Total Commander is blocking from the program run in full admin mode.

Anyways, Nando4. Thank you. I'll report back, after I set my eGPU setup.

Nando4, thanks for the PM.

I think I found the cause of the problem.

When I run the setup-disk-image.bat with the Admin mode and UAC mode off, I see "bcdedit not detected" in the middle of the mounting process. I think this is the problem. I checked my bootloader setting typing bcdedit as you described in your manual installation process, and I only see my Windows 7 booting options. Do you know what can I do to ensure bcdedit is detected?

Thanks,
