I have a Zotac Geforce GTX 670 AMP! Edition, which has a core clock of 1098 MHz, but when i ran 3d Mark 11 (the free "standard" preset), the results tell me its running at about 862 MHz. why is it running so slow? Is there another way to test my core clock speed?

Kepler downclocks if heat is toooo high. Usually Zotac cards overheat even more worse than the normal stock EVGA cards. Your card might have been protecting itself
 
I have MSI Afterburner and when im at >90% load in games it only gets to about 65 C. The AMP! edition cards have custom cooling so it never gets that hot. I want to test my card to make sure its putting out what its suppose to
 


what is the "overlay"? i have MSI Afterburner to tell me percentage used, fan speeds, power, and temps butit dosent tell me clock speeds or anything
 

Its OCD On screen Display:) I didnt know about it till 2 moths ago :) Its soo cool and come with afterburner.Just enable OSD in Afterburn
