i was given a working p4 2.53 cpu which rates as 533mhz for rdram memory..but i dont want to go with that..so i found out that i can use a 800fsb mobo with ddr ram..i allready got a agp geforce 6800..so i get the chance of upping to a 800fsb cpu later...my q is what will i get out of my 2.53..i know it isnt rated for hyperthreading? what will it run at,will it o/clock,or will it stick at 533mhz,and what will the ram run at?
It'll work just fine at stock speeds. The 533MHz doesn't correlate at all into what type of RAM you use. It's native FSB is 533MHz, and that the case if you use DDR or RDRAM. It will overclock, how much depends, but if it's a Northwood core, I'd say you stand a very good chance of jumping over 3GHz very easily. You're RAM is likely to be set to run synchronously with your FSB, although you can change this in most BIOSes so that the RAM runs faster. With the Pentium 4 and up, the FSB is quad pumped. 4x133=533 (effectively), and the 133MHz is what correlates to the RAM. You'd only need PC2100 DDR to start with, but you wouldn't hurt anything running PC3200 simply because the PCxxxx is the maximum speed rating.
