I have an NVIDIA 7500LE (Limited Edition) with 550/400MHz (550/800MHz w/ TurboCache).
When running the Counter-Strike Source Video Stress I got result: 44FPS. The GPU Temp under load was about 86C.
Then I overclocked my GFX card to 625/950MHz and its fine, 92C underload and 65C when idle.
The CSS Video Stress Score was 55.82FPS after overclocking.
I'm using X4 extra fans each running at 2600RPM and blowing the air out.
So is it a stable overclocking? 92C under load...!
Can I overclock more???
P.S. I used software-based overclocking. I can't buy new hardware because of PSU restrictions... CAN IT DAMAGE MY HARDWARE EVEN IF ITS NOT OVERHEATING?????????????????????????????
The Max temp for my GFX card is 105C....
You can generally overclock until you start to see artifacts on the screen.
Of course, overclocking anything shortens the life span of the product, the more you overclock, the more you stand the chance of ruining it. 92c is warm for a GPU, but not terribly bad. Over 100, you could shorten the lifespan of the card by quite a bit. But it is a chance you take, it might run for 2 years at 105c, or it might run 2 minutes. There is no way of knowing for sure. If you want to overclock, you take your chances.
