Ok, the rep is flowing chaps.
Correct me if I'm wrong, please, but I think I'm starting to understand that I have two main options. I can increase the multiplier on the CPU which will keep the FSB at 400, so DDR2 800 RAM would be in a 1:1 ratio with it.
OR, I can increase the FSB, in which case having faster RAM like the DDR2 1066 I originally had in mind would be more appropriate.
Assuming I'm right, which of these two routes is most appropriate with this hardware?
Also, I can't afford an X48 board like the P5E Deluxe, and was recommended to go with a decent P45 board like the P5Q Pro.
The funny thing is that this isn't my first build or my first OCing venture. I've got an old Prescott on WC, and at the time knew exactly what I was doing, but it's been so long and I've been so out of the loop with how the tech has developed that I can't remember how to do things. It's like having to learn it all over again.
