I overclock my 7600GT CO GPU clock from 580 to 640 and encountered some interesting problem. Everytime after I oveclock, when I run 3D games, within the first 5 minutes usually, the screen will freeze for about 5-10 seconds, and then everything will go back to normal again (similar to a network lag), and it will not happen again afterwards unless I restart the computer and redo the overclock. When I reduce the clock to 620 it won't happen.

Is it a normal thing that tells me I have overclocked too much?

Yeah, it looks like you need to crank up the juice a little bit, if you are using a generic PSU i don't recommend overclocking, the performance over an extra 30 on the overclock won't be that significant so if you got it stable at that, you should probably leave it at that

Should I really cranking it up more when it's already not "stable"? I tried to push up to 670MHz and it still have the same "freeze then back to normal" symptom.

I'm using a Ultra 500W PSU so i think it should provide enough juice for a 7600GT

Just by chance, do you have APIC disabled in BIOS?

I think it's enabled by default

EDIT: ACPI and APIC are 2 different things right? Should I have APIC enabled or disabled?

I didn't mean the clock speed, i meant the power supply, i wasn't really specific so im sorry about that, i had that issue back when i cranked up my old 9800, it was due to a power shortage, 285 just didn't cut it (lol no where close), but a 500W should be fine for that, not sure if the ultra is a good brand, but regardless that shouldn't too much of a concern for a 7600GT
