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.

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

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?

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. 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
