I'm new to overclocking, I'm using stock cooling and have been messing around a bit on my card. It seems that if I run the memory past 363/364MHz, I get a lockup. And if I run memory at 360 for over 5 minutes at full load, I get errors(I think it was memory errors and not the core, I was overclocking both at the time and was at 420 core/ 360 memory). Btw I use ATITool to detect errors.

I think it's best if I leave the memory alone since I have no extra cooling for it. As for the core, I've overclocked it to 399.60MHz, not very much at all, and it's stable for over 5 minutes at full load.

Without touching Memory, and having core run at 399.60, I run at 40C idle and full load around 67C.

I don't want to damage my card, and I think I've been pretty careful so far...I'm just curious how high I can safely take the core on a stock cooling solution.

I never get alot out of video cards, 40-50 mhz for video cards I consider high.

some cards clock better than others, my 7800GS goes like 100Mhz on the core and can't remember on the memory, but pretty good, but i leave it @ defaults, not really worth it much to me in games.

i usually just go up to the max that coolbits finds for an OC

with stock cooling i wouldn't go much without testing for some time to look for artifacts.

So maybe 20-25MHz would be safe? And, do you know of anything better than ATITool 0.25 Beta 15 for overclocking an ATI card?
