anything BELOW 80c is a good overclock, in my book.

I cranked up the voltage to 1325 Ma, i wont go to the meax of 1350, as i never like going max on the voltage.

Core clock, ive pushed it to 1040MHz and Mememory clock to 1400 MHz.

Thats a 15% increase on the memory and a 22% increase on the clock.

All running with a nice stable 74c after 10min on kumbustor, although I do have a fan blowing directly on the card as well.

Fan speed is around 70% which is good as well.

Thanks.

what i didnt know is that ‘my’ timings are that impressive, so some people and this review told me. i am not sure about if i did something wrong while overclocking, maybe you can tell me.

settings so far:
gpu clock: 1025mhz
vram clock: 1300mhz
voltage: 1.200 volt (stock?)

i used newest afterburner and kombustor and found no errors. in addition 3dmark06, 3dmarkvantage, unigine 2.0, farcry2 bench and crysis bench went flawless too.

is 1.200V the stock voltage ???
need to check with RBE.

check detailed system specs:

i had my sapphire vapor-x hd 5770 @ 960mhz @ 1125 mV.. gave 7 errors.. at 1150 mV, 0 errors

occt works on cpu’s, (occt:cpu test)
it has a burn in feature (occt:linpack test)
a gpu test
and a 3d card memory test (for nvidia cards, its memtest86+ converted to cuda)
also a torture test for psu (loads linpack and gpu test to get the max wattage out of your psu..)

its a great tool since it sees artifacts that a human eye cannot see (eg 1 frame artifacts at 120 fps = invisible..)

try it, i bet you will love it
