Cloud, the maker, advised to fix V6's voltage dropout issue: "There is a MP2307DN chip on the motherboard, replaced with new can." Go figure what that means. When trying to get an understanding of what this means I got the response "Is this chip, the number in question was not much, thousands of three probability."

Must be google-translating.

Probably... Well there probably is solution which is not connected with the actual GPU, i just don't have such knowledge in electricity. Maybe some electrician will stumble on this post. xD

Maker of EXP GDC V6 advised me that the voltage regulation circuitry on it had been revised in subsequent version (Beast) to prevent such dropouts. Still, if you want a better solution I'd advise getting a PE4C V3.0. It's soldered cable ensures best possible Gen2 and even Gen3 signal integrity.

Well i hoped that there are some voltage regulators or something as i have spent loads to try and fix the problem (DIY 3.0, another PSU and UPS). I really hope there is cheaper solution.

So i have had help here before when i thought that often nvidia driver crash was caused by different PCI gens. I am runnning Acer v3-571g with EXP GDC v6 and GTX 750. Turns out the problem is fridge. :D As i understand when fridge turns on, there is voltage drop in the whole electric circuit and there is not enough power for eGPU and it crashes. Which means, every time fridge turns on/off i get black screen for couple of seconds and nvidia driver sometimes crashes. I hope someone understood my problem and i am surprised i am the only one so far with such problem.

What i've tried so far... Instead of atx PSU i tried Dell optilex, did not help. Also i bought Orvaldi which did not help. I hope someone here can help me out because i have no idea how to avoid these jumps in power. And yes, its definitely caused by fridge (voltage drops) because with fridge turned completely off, i get no problems.

P.S. Does my dell PSU makes hissing and sometimes sparkling sounds when it is working, is that normal? It does not get hot.

Like @Tech Inferno Fan recommended i used DIY setup to try to fix Nvidia driver crashes. I tried both, changing GEN1 and GEN2 link speeds and i did not work. However, when i choose any of those is asks "Do link restraining". What do i have to choose there?

I dont know what else can i try. Could PSU cause this?

These are the specs:

And as i mentioned above there is some screen flickering in games, not very noticable but still. And also when in-game PSU makes a little bit weirder noises which are not caused by spinning fans. In windows enviroment that does not happen.

Daym this setup is getting costly.

P.S. When i press test chainloader it shows this:

Just sent you a payment, hope to get setup soon

Yes, Setup 1.30 can downgrade your mPCIe link to Gen1 to resolve your problem of an unreliable Gen2 link you describe at http://forum.techinferno.com/diy-e-gpu-projects/2109-diy-egpu-experiences-%5Bversion-2-0%5D-467.html#post129275 .

Oh and i forgot to mention before. In any games there is a little screen flickering (only when actually playing, in loading screen or pause there is no flickering) but in windows enviroment there is not. Is that caused by the same problem?

@Tech Inferno Fan If you remember my problem... Are you 100% sure that your DIY setup would fix my problem? If it didn't help i would have spent money for nothing.

It seems that we have a similar setup, and I hope you can help me. I have an ASUS Q501LA with a external GTX750 with a EXP GDC. I am trying to get the eGPU to use my internal display by enabling eGPU + iGPU. I can't do this because of TOLUD issues in which I have to do a DSDT override. I am not able to complete this process, so could you inform me how you were able to flash unlock your bios?

Some guy had unlocked it and uploaded in the internet with instructions. I don't know if that helps because i don't have Asus laptop and my problem is different.

Those options change the Northbridge PCIe slot that hosts the dGPU to Gen1, Gen2 or Gen3. They have no effect on your expresscard slot attached to the Southbridge. Your options are then as outlined in my last post.

2nd option is possible only with 25$ donation? Please tell me that there are other options :/

Your eGPU adapter configuration isn't fully Gen2 compliant resulting in PCIe link retransmissions which eventually fail with the NVidia error you have.

Two solutions to consider: (1) can try other eGPU adapters like PE4L 2.1b with soldered ends giving better signal integrity (2) use Setup 1.30 with your existing eGPU adapter to downgrade your mPCIe link to Gen1 speed where you'll no longer : http://forum.techinferno.com/diy-e-gpu-projects/2123-diy-egpu-setup-1-30-a.html#post27337

I have options in bios to change PCI gen, would these work?

@Tech Inferno Fan What exaclty do i have to downgrade? Could you explain more about dowgrading to Gen1 speed? I have some PCI related options in Bios. I am half broke student so i'd like to try everything as spending more money on this stuff is almost not an option.

Hi guys, so recently i tried to join Laptop gaming as well buy buying EXP GDC dock. Installation worked well although i had to flash unlocked bios to disable Nvidia card which was in laptop. My setup is Acer V3-571G with i5-3230m, 6gigs of ram. EXP GDC and 350w PSU. For GPU i am using Nvidi GTX 750 OC edition from Gigabyte.

So i had installed driver and restarted computer and launched Tomb Raider to test the performance. It ran un Ultimate settings. Yay! AND THEN BAMS. Screen goes black and then normal again and it shows that Nvidia driver stopped responding, crashed and has recovered. I thought oh well, i red that it happens sometimes and carried on. Nope, after like 3-10 minutes it happened again, sometimes it happens even after 2 minutes. Sometimes after 15. What i've tried so far:

-manipulation with switches on EXP GDC. Didnt help.

-installation of older drivers. Didnt help

-using windows 8 instead of 7. Didnt help

-various settings in nvidia control panel. Didnt help.

So has anyone met this problem or i have a faulty EXP GDC adapter? I thought that may be my PSU could not handle GPU in games but i dont think thats the case because these crashes happen even when not playing games. Writing this it happened 3 times already. I noticed that CPU usage skyrockets when crash happens (MSI Afterburner). And no i didnt overclock the hard, i even tried to downclock it. Could PSU cause this? It's kinda old but i think it still should be enough for 750. If necessary i can provide PSU's stats.

I would appreciate any help as GTA V is gonna be release in the next few days.
