I have an EVGA GTX 660 FTW ACX which has a core clock of 1072MHz and I have OCed it to 1117MHz. However, my card seems to be overclocking itself to 1200Mhz which may be causing errors in my games (crashing with DX11 errors, may not be due to this. but still).

I use EVGA Precision X and MSI Afterburner and do not understand what could be causing this.

MSI and EVGA Settings:

is your afterburner "Apply Overclock at Startup" selected?

2 words. GPU Boost.

It is overclocking itself as it is within it's power threshold so will push itself up to a certain point. Unfortunately it has no idea that it is pushing itself to far and causing the crashes.

TBH if 40MHz is the most you can get out of it then I wouldn't bother with core clock. You might get a bit out of memory but 660s are not famed for OC potential.

Also don't use MSI AB and EVGA precision X at the same time. You are going to have a bad time.

Thank you for fast input. I have turned EVGA Precision off and am now only using MSI. However I don't know how to turn GPU boost on or off

You cannot unless you flash a different bios. So for now I would just leave overclocking - your card just isn't one of the lucky ones that can OC very well. Unless you can find a different bios (i know one existed for my Twin Frozr GTX 660).

I have slightly underclocked it a bit since to the point where the DX11 issue no longer plagues me. However the core clock still hits 1200MHz... I can't leave the overclocking because it goes into power mode and I don't know how to turn it off :( 
I understand your point and thanks for the reply!
