how much can i overclock my GPU (GTX 660 Superclocked)

[Jon Simes]

Hello, i'm wanting to overclock my graphics card because i think i can.

My spec:
Motherboard - MSI - Z775
CPU - i5 3570 (Non K)
Video Card - EVGA GeForce GTX 660 SC 2GB GDDR5
RAM - 8GB corsair 1600mhz DDR3
Hard drive - 500GB
Power supply - 550w
Monitor - 1920x1080

this is the exact card i have - http://www.amazon.co.uk/EVGA-GeForce-GDDR5-Graphics-Card/dp/B0099AOD50/ref=sr_1_1?ie=UTF8&qid=1381102216&sr=8-1&keywords=660+sc

I have not changed any of the settings on it since i got it, what OCing can i do which will be safe and how much perfomance increase will i get ?

Thanks in advance

my gpu clock did not go higer than 549mhz

You will likely plateau around 1200 MHz core with boost enabled unless you flash a different bios to unlock the voltage.

Here is a good thread for bios modding the 660:

I have this exact same card... I overclocked it by 100 mHz extra... Do not attempt to exceed 150 mhz because this is too much and will crash your computer and potentially damage your gpu.
