I'm running an AMD Athlon AXIA 1GHz chip happily at 1.333GHz on an ABIT KT7A, but had some issues getting it stable (which it has been now for many months using Win2K). Here's my tuppence worth:
- Get a decent heatsink (a question of religious proportions). I'm using a Thermoengine job with a 7500rpm fan, from overclockers.co.uk (see also Telemart, IIRC). Check out the various reviews on the web WRT to heatsink efficiency etc. - Check your motherboard supplier for a BIOS update: an earlier version of my BIOS caused the CPU to run cool (mid twenty degrees) when 'idle', rising rapidly to the high forties under load. The more recent BIOSes maintain a steady temperature (low forties, IIRC), which is probably better in terms of wear and tear. - Check your graphics card isn't the problem - my olde Matrox Millennium G200 AGP seemed to suffer from heat - solution: cut a hole in the case and mount a fan blowing air over it (and other cards).
