Tbird 1 gig voltage funk

[joeryu]

hi, i was testing this 1 gig tbird and i pumped the voltage up to 1.85 on an iwill kk266 and ran it at 1.2 gig, 8x150. The pc would reboot once in a while, with some BSODS in win2k. i thought hmmm, must have a not so great chip. then i lower voltage to 1.8 and it is ROCK STABLE. could it be that the the cpu couldnt take the extra heat at 1.85 volt so it rebooted, while 1.8 was enough juice and it produced less heat to run properly?? i was funked by this, im gonna try lowering even more.

You hit the nail on the head. Many assume that cranking the voltage gives them an overclock but they forget about heat.

I see a lot of people on this forum jumping to more voltage thinking that that is what is needed for a good overclock, when in fact, a good overclock is often made of a combination of GOOD COMPONENTS, good cooling, a little I/O voltage tweaking and the right core voltage.

I've been finding more and more lately that some 1GHz+ chips don't seem to overclock at all without increasing I/O voltage to 3.4. One in particular (the one I'm typing on) is a 1.1GHz that wouldn't O/C even to 1,130 at 1.85v. Right now it's at 1,230 at 1.825 but with the I/O at 3.4.
