Hi all, We have a single P-III 1ghz (coppermine) in our office server. We just aquired a very nice Dual P-III motherboard. If we can find another 1ghz CPU, I'd like to move it over to that board. Two questions: 1. Is it true the tho CPUs have to be pair/couple that matches in some or other way? I have read something to that effect, but it was not clear which CPUs have this requirement. 2. How big an operation is it to move linux from a single to dual CPU setup? The OS is SUSE 9.1 Pro, installed with default kernel. Would simply removing the current kernel and installing the smp one? Thanks -- Kind regards Hans du Plooy Newington Consulting Services hansdp at newingtoncs dot co dot za

Not sure but I think they should be the same speed.

Just install the smp kernel and reboot. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998 * Only reply to the list please* "The day Microsoft makes something that doesn't suck is probably the day they start making vacuum cleaners." -Ernst Jan Plugge

Yes. Ideally, an identical pair. Same model, same stepping. At least the same voltage and clock speed. I acquired a dual PII board, cheap. It came with one CPU. I ordered a second PII CPU, same speed. It will run with either one, but not both. Turns out one is a 5 volt CPU, the other a 3 or 3.3 volt CPU. The motherboard can handle either one, but not both. Deschutes and Klamath models. HTH, Jeffrey

Wonder if Intel environment is, in this respect, so much different/critical than other hardware. I have a Sun workstation (running Suse7.3), two cpu's with a speed difference of 50%. Yes, not the most ideal situation, one cpu get's more work done, but it works.... If any contraints, its not the OS, but the motherboard. Hans
