One is that every time a computer reboots, there is a possibility that the Hz count can change by 1-2 Hz in either direction. *nix seems to be more sensitive to this, but I've seen it in Windows 2000 as well. The second is maybe a non-issue, but if the servers have shared video memory (even 1-2 MB), it can make a RAM count look ugly if you divide by 1024 and get something like 3.998046875 GB of RAM instead of 4 GB. Things may have changed since I last experimented with Windows 2000, though. A couple of things to be careful with.
