A good read...
It will hepl out a lot.
The part that can be a pain is the different terms in the BIOS
HTT or LDT or Memory bus sometimes it's multiplyer is
5x, 4x, 3x,
where as others use 1000 for the 5x, 800 for the 4x and 600 for the 3x.
The thing is the HTT is 5x200
default and as you up the CPU bus OCing so does the 200
of the HTT increase so drop to 4x for up to 250 and drop to 3x if you get the CPU bus higher than that.
Also the RAMs default speed rating gets effected and requires various solutions.
1. Up the voltage
2. Relax the RAMs timings... more on that later
3. Use a divider or set the RAM to DDR333 or DDR266
Among other things
