Asus R9 270x voltage question

[Mike Undercovah]

I am overclocking this GPU once again and it seemed to be relatively stable @ 1235 & 1500 MHz (Core & Memory). Any further in the core, and it will start showing artifacts every so often, and it just crashed at 1255. So thats beyond the max of the core clock.. Is it worth going up in voltage? Temps are still very reasonable:

Heaven: 60 Degrees
Furmark: 65 Degrees with some slack in the fan speed~


By how much do you guys recommend I should up my voltage by? Power Control is already at 120%

Also what is the max voltage a gpu can handle, or is it totally up to the temp's youre getting?

Thanks!

I would just bump the voltage until you hit the 70 degree mark. 65 degrees is quite chilly for a gpu

Tbh, i've tried to overclock this gpu more. I added 25 voltage in steps, and nothing improves stability. Think around 1200/1500 may just be the max for this card lol. Any thoughts? Add even more voltage?
