Since you're using an Intel P4, and that probably means an 800MHz FSB, there is absolutely no difference. Get DDR2-533 with tighter timings, anything over that with an 800MHz FSB is overkill.

Higher memory ratings means you can overclock more. If your fsb goes up, it pushes your memory frequency up (unless you use a memory divider). If your cpu can take a massive boost through the fsb (multipliers are locked on just about all cpu's except FX and EE) then higher clocked memory modules can come in handy. :D

Ex: My Corsair DDR400 couldn't cope with my fsb being pushed up past 270, even with a 5:4 (166) memory divider. Great RAM, couldn't cut it. Threw in some OCZ DDR500, can run Prime95 for 10 hours (probably more) at 290fsb (the memory is actually running slower than rated, but the timings get tighter, so it's a good thing).

Now for my own question!

On CPU-Z, in the Memory section, under the frequency, is 'FSB:DRAM' and to the right is 'CPU/12'.

I've seen it change to CPU/11, or 15, depending on how I set my BIOS (fsb, memory, voltage, etc.)... anyone tell me what it means?

Thanks,

CPU/10 means you're RAM is at 10x less than CPU, so if your CPU is 2400MHz, and your RAM is 240MHz (DDR480) 240x10=2400. CPU-Z is getting stupider, ignore it's RAM divider.

Right on, right on! Thanks Triple-M and Wusy! :wink:
