Switch CPU without OS Reinstall?

post #1 of 21
Thread Starter 
I got a Q6600 about a month ago, but when I did, instead of reinstalling the OS, I just took out the old proc and put the new one in. I didn't do anything else. Should I have reinstalled the operating system to get the best performance or what?

No, you never have to reinstall a OS for a CPU switch.
Once again...

I've swapped my CPU about 14 times since I've had my current install of Server 08

sorry to argue this duckieho. this may be the case with intel cpu's (which i know we are in the intell section), this is not the case when switching of amd cpu's. each time i switch my cpu from dual core to tri core and tri core to quad core, i had to reinstall the os to get it to registar correctly. device manager seen them properly. but everthing else seen it as the old cpu. a format fixed the problem. but i guess its kind of a point less post seeing the section we are in.

sorry.

That may be the case, but the OP does have a Q6600.... so he's talking about an intel CPU, which do not need a reinstall for the OS if the processor is switched
