It's been a long time since I built a PC, and I can't remember the methods for over/under clocking it. I have an Intel P4 1.8GHz processor, and PC133 SDRAM memory. However, I've been running this machine headless for a while and after plugging a monitor in and seeing the BIOS initialisation, I noticed it set to PC100.
What's the calculation for setting this up? Should I basically set the FSB to 133, then whatever multiplier required to get the desired 1.8GHz clock speed?
Sorry this question is so n00b, but I've totally forgotten everything I learned when I built this thing.
I don't want to overclock it - I just want the "correct" settings (ventilation isn't great where the tower is situated).
I noticed the BIOS settings were memory speed = "auto" and the multiplier was "x4". I've changed this to 1333 x 13 ( = 1729), but not seen any noticeable difference. The BIOS POST states "Intel (blah blah) 1.8GHz (100 x 1.8). Could it be overriding my settings with something else?
