post #21 of 31
I run CF 1000MHz each @ 1.225v

Max temp while playing BFBC2 tonight (happen to be logging for other reasons) was 64*C on XFX card and 58*C on Sapphire

Max temp on Furmark for 30min from 2 days ago was 79*C for XFX and 68*C for Sapphire.

Can you 'Fold@Home' with that OC setting? Ive been stable for hours using Furmark at 1000MHz-1.25v, but crash in 10 min of Folding. Only stable at 950-970MHz while folding

Why not reduce the voltage to the recommended stock of 1.125, and then see what kind of OC you can get without voltage increase?
Take up the volts when you hit the stock wall, until then I wouldn't worry about a new cooler.

what is the difference of 1.3V for 1125?
post #28 of 31
Ummm... .175V?
I'm just saying that I dropped mine from 1.250 to 1.125 and saw a drop from 90C to around 70C under load.
This was at stock clocks.

It went 1.5hr with no problem before i stopped it. That's CF 5770s @ 1000MHz each core and 1360MHz memory with 1.225V. Here is the log:

Folding CF (1.5hr) 1.225v 1000_1360.htm

1.125V should be stock voltage for 5770s

FYI: Even just adding OCZ freeze or similar silver paste to stock heat sink and reinstalling it can reduce temps 5*C or so.
