Max overclock for GTX645

[PenguinAreOCD]

My GTX 645 runs at 30C at 50% load, and at max load 50C plus the fan doesn't ramp up from 30%, if i overclock i could make it run at 50% or 90%

I didn't found any web page that indicates the maximum overclock in this graphics card. So go and do it manually. 

 

As it is a low-end graphics card, probably you can't raise the clocks too much.

determined by gpu and voltage limits. just crank slider until it doesn't work in games anymore and back off from there.

 

as gtx645 is an oem card (likely alienware) you probably wont get much from it
