Does overclocking decrease performance?

[imeem]

So according to 3D Mark Vantage, my gpu and/or cpu scores decrease if I set the Mhz to a certain range of numbers.

Is this suppose to happen or is 3D mark vantage is wrong?

Also which one to overclock more? the GPU clock or Memory clock?

 

[richc46]

Slight over clocking is suppose to improve performance. Pushed to far it may decrease performance and even cause problems, such as BSODs, I suggest forget overclocking.

ok but, is overclocking the GPU better or the memory?

 

[richc46]

I think that will depends on the purpose of the OC, but on average, I think gpu results are more consistent than memory OC.

How Do I know if I reach the limit of my video card?The temps r below 80 C in Furmark, I see no artifacts in games and benchmarks, and I pass the stability test in AMD overdrive and in Furmark.

I would start over , set it to stock and test it for performance , then adjust the speed of the gpu and ram some..and re-test.. Usually when you push a card or even a computer voltages need to be increased so dont expect a huge overclock on anything if your unable to adjust voltages
