So I got my r7970 a couple days ago and finally got around to fiddling with it.
I was able to pass Heaven (max settings) and 3Dmark11 performance setting multiple times with the following OC:
Core Voltage - 1231
Memory Voltage - 1600 (Stock)
Aux Voltage - +30
Core Clock - 1225
Mem Clock - 1500
Power Limit - +20
Temps are maxing at (during gaming) :
GPU - 63
Mem - 55
VRM - 57
I use RadeonPro with custom graphics settings (Max AA, AF, etc) to play Far Cry 3 and since I overclocked the gpu the game will randomly crash. It will freeze for a second and then I get a white screen where I have to ctrl+alt+del to close it.
I bumped up the Core Voltage to 1237 and this seemed to help for a few hours but then it crashed again, same as above.
I'm wondering, should I be bumping up the core voltage yet again and what is the safe area for max voltage (and subsequently what kind of core clock should I be around at that point)?
or
Should I be bumping the Memory Voltage since I haven't touched it yet?
BTW, this is my first gpu I've ever tried overclocking so while the concept is the same as a CPU, the execution is quite a bit different especially with this card having 3 controllable voltages.
Thanks for your help team.
[edit] Btw I'm still on air because I haven't gotten around to purchasing the rest of the watercooling stuff yet but this isn't a final overclock, just something along the lines of what I'm comfortable with for the time being.
