Oc'n GPU

[Jason8284]

I'm going to try an OC my GPU a bit, and see if I can get results that I'm sattisfied with, instead of buying a new GPU. I'm using RivaTuner.

Core Clock: 513

Shader Clock: 1188

Memory Clock: 792

These are my default Clocks, and I want to know what is safe to mess with, how far can I push it, and what temps should I start slowing down from Overclocking? Also can I ruin my GPU if I'm not careful?

Also I have a pretty good airflow going around my gpu.

you can go pretty crazy with the clocks on a GTS, the core can reach temps in excess of 100c w\o overheating. you will run in to stability issues before heat issues.

just higher them 5-10mhz at a time, there is a guide as a sticky too

Try 680/950.

My ram won't go past 950

EDIT: Which driver are you using?

3DMark06 wasn't reading the card speeds correctly but this is my compare url

I'm using that new beta driver for Crysis SP

You may find that ocing is disabled under that driver with Rivatuner, saw a couple of threads mentioning that over on Guru3D

I rolled back to the other driver. Crysis runs superb on Very High Settings.

My OC on my GPU is...

Core Clock: 594

Shader Domain: 1404

Memory Clock: 864

I set my GPU fan fixed on 75% to keep it a little cooler. By OC'n my card by that much, will it destroy my card? I'm hopping to get at least 6 months out of it until I have to upgrade.

Should I try OC'n more lol, or should I leave it? I'm just amazed what OC'n can do. Bought me some more time before I need to upgrade.

i highly doubt it will mess it up. I used to have a 6600GT and I pushed that thing to the most extreme limits I could to avoid having to upgrade and it still works today.

Its hit and miss with GPU's. Mainly the luck of the draw on if you get a really good overclocking card or a poor card. So as they said you'll just have to try settings to find your max. After you find max the only way to get more would be a volt mod. Thats complicated and will void your warranty so I wouldn't recommend that unless you know what your doing. My overclock settings are.

Core: 675
Shader: 1556
Memory:1008

 

[Jason8284]

TY all. The highest I could get before GPU would act weird was...

Core: 621

Shader: 1458

Memory: 1008

I don't think that is too bad, I'm satisfied with it. It runs my games great.

1 more thing, with rivatuner it wont let me change the low power 3d core, is there a reason why? or do I need not to worry about that 1?
