GPU causing BSOD

[Psycho349]

Hi,
I recently bought MSI HD 6850 Cyclone OC. It's causing bluescreen in random moments (PC sometimes work for 2min and sometimes for 4h without any error). Even reducing core and memory clock (from 860Mhz to 300Mhz for core and from 1100Mhz to 550Mhz for memory, it was the lowest possible) didnt help. I tried with 3 versions of drivers: Catalyst 13.9, 14.12 and 15.7.1 (newest) and changing drivers also didnt help. It's really weird because when I stress GPU (even when it's overclocked) and it's 100% of usage and my monitor is connected to integrated video card everything works fine, only when I reconnect cable from integrated GPU to dedicated GPU, monitor suddenly goes black and PC restarts, it happens about 4/5 tries of changing display provider. BSOD BBCodes: 116, 124; 116 occurs more often than 124. And I know it's problem with my GPU because I tried with my friends GPU and worked fine without any problems.

My specs:
CPU: Intel Core 2 Quad Q8300
RAM: 4GB DDR2 OCZ 400Mhz
GPU: MSI HD 6850 Cyclone OC 1GB GDDR5
PSU: beQuiet 600W
MOBO: ASRock G41C-GS

Sorry for my english but I tried my best in describing my problem, if u need any more info let me know

did you mean that when doing stress test on gpu you connect the monitor to integrated gpu output instead of the gpu itself?

Yes

 

[renz496]

you need to connect your monitor to the graphic card. because if you connect the monitor to your integrated the one that being stress up will be the integrated one not the gpu.

But now something went worse, because even when monitor is connected to integrated gpu, dedicated causes bsod after 10 min of using and earlier when i connected monitor to hd 6850 it was bluescreen and restart but after about 2h now its few minutes and before pc restarts there are artifacts on screen.

Temperatures are stable at 50C when idle and no more than 60C in stress, when I set fan speed at 100% it's about 45C in idle and 55-57C in stress so I think temps are good (+100C causes force shutdown)

try running memtest86 just in case. faulty RAM also one of the major suspect causing BSOD. have you tried using the gpu on other PC?

I tried gpu on other PC, same problem as I have, pc was restarting by itself.

 

[renz496]

then the gpu you bought most likely faulty.

I know but maybe I can do something with it because I dont want to buy new gpu :/

 

[renz496]

can't return the gpu?

 

[Psycho349]

Thank you for helping @renz496 , finally I know what was causing problem, it's how you said , gpu is a little bit burned inside, I cant return it because I bought it from Allegro (polish eBay alternative) and there are really big problems with returning :/ It's unrepairable, so I fortunatelly bought for a low price HD 6970
