Safe voltage?

[Shadyss]

Alright so I decided to overclock my GPU (Sapphire r9 270x 2gb OC) and this is the most stable I've gotten without touching the voltage at all

 

Stock

Core: 1070 MHz

Memory: 1400 MHz

 

OC

Core: 1200 MHz

Memory: 1500 MHz

 

The stock I got 27.2 FPS and 686 score.

 

OC I got 30.3 FPS 765 score

 

My Temps have been around 65 Degrees. Not going to 70 at all.

 

These results were on Heaven btw.

 

 

It was doing fine when higher but sometimes it would randomly give me a black screen during the benchmark and would give me less results.

 

Does anyone know the safest voltage I could go for with this particular card? And does touching the memory even do anything?

 

 

Thanks.

Some people go all the way up to +300mV on the core on AMD cards. I'd say keep temps under 90 and you'll be fine.

I've gone between 30-40mV on my reference 980's without an issue. I'm sure it varies.
