inno3D 6600GT agp not oc very well

[bof]

hi all. im trying to oc my inno3D 6600Gt agp... the defaults settings are a 500mhz core clock and 1ghz memory bus. i oc the core clock to 570mhz and the memory bus to 1.04ghz... but i can't go any further...i tried to raise the agp voltage (from 1.5v to 1.7v)...but im stuck at these values...the prob is that i heard some guys successfully oc their 6600GT to 620mhz and 1.3ghz... does someone knows how can i do that? im also having artifacts under games but not on 3D mark 2001 and 2005. by the way im using 78.01 drivers.

HAD THE SAME PROBLEM IN THE PAST WITH GEFORCE4TI...
YOU SEEM TO DO THE GOOD THING VOLTMOD ECT...

Why are you complaining, that's not a bad overclock. That's a 14% overclock on the GPU. Your 6600 GT may be different than the one in my other machine, but it has default memory speed of 900MHz. I'm able to get mine to 1.1GHz stable, 1.17GHz if I try really hard. If yours is indeed a 900MHz card stock, that's still a 15.5% overclock. If it's 1GHz stock, then it's faster than most 6600 GTs (I saw a Jaton 6600 GT on newegg that came with that stock speed). So what all of this boils down to is that yours is in good shape... no worries. The high clock speeds you mentioned must have non-OEM cooling. You could always look into upgrading the cooler on your card to overclock more, but it's not worth it in my opinion.
