anything over that crashes and i have to HARD reset...Guess i got some crappy overclockers?

Did you up the max voltage that would be supplied? Did you up the power maximum as well?

Just max them both. The only reason not to max the voltage is if your maximum boost is being throttled by power percent (rare).

I haven't seen a reason not to max the power target yet. Keeping it lower can only artificially create stability by forcing the card to throttle itself before it hits an unstable core frequency, but the card itself isn't truly stable. This is the case on some of the stock Asus TOP models which are unstable at factory stock overclock settings.

But for you, i see no reason not to max both thumb.gif

Hey man, you win some you lose some. The CPU I got in my build now is the worst I have seen of anyones reports on the forums. Most people can get 4.4 GHZ at the stock voltage or even 1.1V. Mine isn't even table there at 1.28V. Don't worry too much, the difference you will see between 65 and 85 is nothing tongue.gif

Almost found my sweet spot:x

Went up to 1250(maxBoost)-3374(mem)(+370 in msi afterburner).

Decided to go between my first stable MAx clock and highest so went for 1245(Max Boost). And am now at 3554 Mem(+550 in msi).

going to try boost mem a bit more to get a 1300 score in heaven With 1245/3554 I get 1294 score 51.4ish FPS pretty happy with it:)

I recently bought a ASUS GTX 670 Top and start a oc based on the guide (well written and useful thanks)
Im not consider a serious overclocker so my question is, can I push even further the oc on this card.

This is the most stable clocks so far, increase 5mhz on gpu or memory heaven benchmark quicly gives artifacts and a error message, that i think is unstable oc
I need increase voltage? headscratch.gif
Note: Voltage is 1.1750v (default).
