*** GTX 670 Overclocking Thread ***

After +160mhz, boosting to 1350mhz, is that the norm with the Windforce cards?

Should i oc the memory too, or not bother?

I think that's probably a good bit higher than normal.

I found that OCing the memory paid dividends too as it seemed to give some fairly healthy FPS gains and bumped up my Heaven scores a fair bit


so im guessing i just got a bad card if I cant boost over 1200?

Quite low I think. I could only get 1250 on mine, which I think was wee bit below average. Although I'd imagine that people with higher scoring cards tend to be a bit more vocal about their OCs than those who can't push things as high ;)

1250-1300 is average for the windforce IMO, should easily hit over +500 on the memory.

Mine will do 600+ on the memory but seems to be stuck at 1200 no matter what i try, temps remain good but keep crashing in heaven and 3dmark11 getting a dx3d error or something :(

Wasnt a clean install tbh and ive swapped a fair bit from amd nvidia amd intel etc recently...... I did however run dc pro before this was installed

Anything over +130 on the core and mine errors with driver stopped responding, memory does 780 mhz stable. Still pretty pleased with those results.
 
Some sound a little disappointed with 1200mhz on the core? 1200mhz with a healthy memory clock (7000mhz effective) will be walking all over a stock 680 & 7970.
 
Not that I'm dissapointed far from it i just wanted to know If I was doing something obviously daft to prevent me from getting higher, im happy leaving it at stock tbh with boost to 1060, the main reason I bought the windforce was for the noise levels and I am more than happy with those :)
 
+160 is very good, I only get +60 for 1184 and +690 on the memory.

It seems there's 2 types of windforces.

one has a chip which does the same overclocks as reference. +60 on windforce = about +140 on reference which is what I can get.

the other ones must have binned chips which can do 80-100 more than reference.

I'm not sure if it makes a difference but my GTX 670 Windforce that did +105 GPU Offset/+675 MEM Offset - PCB Made in China. The GTX 670 Windforce that did +160 GPU Offset/+700 MEM Offset - PCB Made in Taiwan.

What's the recommended software to use for overclocking?
Afterburner seems to have all the required utilities and i'm familiar with it's layout, while GPUZ is handy for information on PCI-e speeds and render test.

However I have seen people telling others to try Precision X to get better overclocks, although they are pretty much the same software could one be better than the other? Some silly bios or motherboard variance?
 
My windforce oc 670 will only do +55 on the core but 750+ on the mem. Stock boost was 1137 and with the +55 and power at 111% it will boost to about 2000 when taxed. It give a 1911 score in the heaven.

As others have mentioned, its whisper quiet though and has plenty of grunt for the games I play, so even though its not a great clocker it was still a great purchase.

[EDIT]

I was just thinking, I used the 2 x molex to 8 pin connector that came in the box as my OLD psu only has 2 x 6 pin pcie connectors. Do you think that could affect the overclock?

I'm using a native 8pin plus a native 6pin so not sure, im using a bequiet 680w psu too, was thinking it might be psu related but I somehow doubt it, your stock boost is considerably higher than mine at 1060
 
is there any sign of any softmodding that could allow you to up the voltage yet? The only thing I feel aggrieved about is I have really cool temperatures and i know I could push the voltage a lot higher if it was possible.

Can't/won't happen afaik, I'd love to be proven wrong as some of these cards could hit in the region of 1500mhz with good cooling.
