The '1600-1800' designation on the Athlon XP is used a performance indicator compared to (of that I'm not sure) classic Athlons or Intel's Pentium IV. It is not the clock speed. However, the top Athlons _do_ run at differnt clock speeds. For example: XP 1800 -> 1533Mhz XP 1900 -> 1600Mhz This has _nothing at all_ to do with overclocking. >They are stamped on the >face, but you can't see it because of the heat sink and fan. When you buy the _chip_, it generally does not come with a heat sink and fan. >They require excellent air flow for cooling, especially for the "overclocked" >CPU's. If you overclock it, then you get to keep the pieces if it breaks. As for non-overclocked chips, they are actually pretty tolerant to a bad installation in my experience, as long as you dont completely botch it. (like, forget to connect the fan) Many people seem to have a quest to make their chips run cool, but there is no real need to, as long as it's within reason. The Athlon can tolerate up to 90C! (but keep in mind that the hardware monitors on the motherboard don't accurately measure it's temperature) >I was looking for a good chess computer/personal computer, and knew the computer >stores wouldn't allow me to run a chess program on their floor models, Depends on the store. I have a motherboard that is officially NOT compatible with the Athlon XP, but I knew from an official source that it usually works fine. I had no trouble finding a store that lended me a chip for testing.

This is probably just as representative for the speed of a typical chess program as TSCP is. (It probably fits in the CPU's cache) -- GCP
