Overclocking AUX voltage

[Simon771]

I have question about MSI afterurner overclocking. So I found out that AUX voltage overclock tab and I decided to tet it out. I set it to +20mV and changed clock from 1040 to 1150 and memory from 1500 to 1650.

My GPU is R9 390 nitro.

I tried to run Valley becnhmark, and after 20sec I got black screen and no video signal. So I force shut down my PC and turn it back on. Disabled that OC and everything was back to normal. That happened 2 days ago, but since then I got like 2-3 times horizontal green line on my screen for like 1sec.

Could that AUX voltage overclocking dammage something on my card? Or it could be random glitch in system?

Because I was playing GW2 for like 5+ hours in last 2 days and never had any problem. But randomly while browsing web, I got horizontal green line for 1 sec.

Temperatures never went over 75°C on GPU and never over 80-90°C on VRM.

 

Any ideas?

When an overclock doesn't work sometimes it tends to be the gpu driver which throws a sh!t fit and hence why the gpu goes off. If you havnt done already use DDU utility completely remove the drivers then reinstall them.

OC needs some tweaking IMO.

See how that goes it should work ok now. Gpu drivers can be a pain sometimes.
