OCing card... Power Limit?

[Jamezinho]

theres a reg hack isn't there to increase the power limit to 50% if you wanted to

Yes there is, although I'm not sure there is much need to go above +20 for most people unless the voltage is being pushed high.

I've got the potential to go to +50 on my card as I'm running a custom BIOS from the 7950 BIOS thread which enables the increased power limit setting.

Strange problem guys. I settled on:
1.15V, 1000mhz and 1550mhz and that was stable for 24/7. Played BF3, BO2, CS:GO, looped heaven, valley and 3dmark 11 and all was well.
I fire up the system today for some more daily dosage of BO2 and the GPU is now unstable on the above OC.
Is this a sign that my card is crapping out?

try a touch more voltage,it simply could have crashed down to cold boot or just turning pc on from cold? idk

I would try with 1.16-1.17v then see how it performs

set power control slider to 20% if you havn't already

 

[WuMyster]

Yeah power is already set to 20%.
I just bumped the voltage to 1.19V for now to get some games in. Just wondering why its done this. Dont mind keeping it on 1.2V but its strange why it suddenly becomes unstable.

it might be fine once warmed up,it could be from a cold boot

 

[WuMyster]

Nah. I had it running from 10 - 2. I think it would have warmed up by then!
