You may find that you can run heaven stable for hours but you crash after an hour of BF3 or something similar. If that happens do the same and back down a bit.

Yup, i could play Diablo 3 on the higher "unstable" clock though but thats maybe because it stayed on 800MHz :O And in BF3 the game crashed when going higher than +140MHz on boost (1,303MHz) and +470MHz on memory (6,956MHz).

I had two goals, over 1.3GHz on Boost and over 7GHz on memory, now i am sooo close frown.gif

what temps do you have when GPU is fully loaded? boost clock will throttle back by 13Mhz when temps reach 70º, and again at 80º
also boost clock raises by 13Mhz at a time, so i only set my offset to 117, 130, 143....etc, the numbers inbetween do nothing different. i saw a list of the clock steps somewhere, i'll try and find it.

Hey, not trying to hijack or anthing, but since this is relevant to my interests, With the increase of GPU clock by 10-20Mhz at a time, how much should i raise memory?

Or rather how should i increase the memory clock? Or should i just leave mem as it is and just do GPU clock?

Do you have a GTX 670? alot of people can get 400-500Mhz offset, try going up in 100Mhz steps until crash then fine tune
if your card is factory oc'd you might not get that much.

That's pretty much my issue ...


At stock clocks, stutturings (no vsync) in BF3.
At +70 core and +450 mem, stable in 3DMark11.
At +70 core and +270 mem, crash in Unigine Heaven.
At +70 core and +250 mem, crash between 5 and 20 minutes in BF3 (no problem in 3DMark11 nor Unigine Heaven).
At +50 core and +100 mem, crash between 20 and 60 minutes in BF3 ...
At +40 core and +90 mem, stable (no "error") in OCCT GPU

Basically : 1190mhz core max (boost), 3096mhz mem max

BF3 : 65% power
OCCT/Furmark/Kombustor : 94% power


I really really thought about sending back the card, but it would cost me too much time/money and force me to use again my good old HD4870 Vapor-X 2GB rolleyes.gif
