I am running 7.04 Ubuntu - if i just swop out the cpu will it still work or do i need to do anything special?

thanks

thanks una

i suppose i should also have asked wheter linux can actually use 2 cores - i assume yes??
and can you get utilities like task manager that show what each cpu is doing?

Sure it can and well you can see the current utilisation of each core, not sure about a more detailed breakdown, never needed to my self.

One thing you need to make sure is that you are running a SMP kernel (on ubuntu its the generic one).

My duel core currently:
Code:

I'm pretty much in the same situation as yourself I have a 3000+ atm and have got a x2 to drop in. I use several different distro's though but from what I understand you need a smp kernel which isnt all t hat difficult. best thing to do would be either nip onto irc or check out the ubuntu forums.

Post back and let me know how you get on!
 
You'll have absolutely no problems at all :)
The only thing to make sure is that you have the standard generic kernel installed pre-upgrade.
My server went from a Via chipset P3 machine to a socket 754 Nvidia chipset without any sort of reinstall whatsoever, all it required was two reboots for it to figure out all the new hardware.

Unlike Windows, Linux simply doesn't need reinstalling unless you seriously trash some very basic files.

thanks guys

a couple of questions though

1) is the smp kernel (whats it stand for?) the same as a standard generic kernel? and how do i tell what i have ---- and

2) if i don't have it what do i need and how do i install it?

i think i am ok as i found this:
title Ubuntu, kernel 2.6.20-16-generic
root (hd0,1)
in my menu.lst file

SMP- Basically means dual-core/ hyperthreaded processors in *Nix technology. Stands for symmetrical multiple processors IIRC.
The generic kernel should be SMP :)

well in the end it all went very smoothly - thanks all for the help and support

now to try the overclocking :)

one more question - there ia an AMD dual core optimiser that i ran for the vista install - is there anything similar for linux?

thanks

Ahh this is good news.

I am running an E6600 in Ubuntu, but a lovely Q6600 [G0 stepping, no less] landed on my doorstep this morning :D

And for the record, SMP stands for Symmetric Multiprocessing. :)
