Hi Everyone

 

So I've just replaced my 780 with a new 1070 but I seem to be having issues with my vms

 

The vm that has the 1070 is showing constant white lines across the screen. If I remove the nvidia drivers so it's showing a very low resolution, it seems fine but the second I install a video driver it gets the lines back. These lines occur all the time regardless of what is showing and I've tried different outputs, display port, dvi, and on different screens

 

I've tried the latest drivers and gone back and tried the last 5 drivers available and it's the same on each one

 

I've also tried the card on a different vm as well as trying it in a different pic express and am getting similar issues

 

Before I get this card sent back as having a fault of some sort, can anyone think of anything else I can check to see if it's a card fault? 

 

I'm on the latest build of unraid with Windows fully up to date

 

Regards, 

Jamie

Toss it into a bare metal Windows box, and try a different monitor

Hi Squid

 

Tried that one now and on bare bones the gpu is working perfectly. Plays doom on ultra at over 200fps for hours on end with no issues

 

I've remove all the drivers on my vm and tried again and the same thing happens. 

 

So I've tried a new power cable to the gpu, different power supply slots as it's modular, new motherboard bios, new windows install entirely and still get the same problem

 

Windows is fine and runs at 800x600 with no drivers, it will even plays videos at that resolution. Install any nvidia driver and I get white lines all over the screen but their not in fixed places and move as I do stuff but make the entire system unusable, it won't even load youtube videos

 

The other vm's on the machine with gpu's are all fine so it's isolated to this gpu

 

Besides posting a system diagnostic, is there anything further I should try before doing so that may provide more needed information?  

 

So far I've pretty much done everything I can think of to resolve the issue, but I'm not a master like some of you here

OK so this issue has been resolved

 

I created a brand new vm with ovmf but change the machine to Q35-2.9 and it's working perfectly on a fresh install of Windows 8.1

 

Its a bit of a strange one and the issue really didn't look like a vm issue but rather a driver or Windows problem

 

Perhaps this will help someone in the future
