I want to buy a new P4 2.4C
Do u think i can OC 2.4C to 3.0 by using DDR2700 (333Mhz)??

yes...you have access to a 1:1, 5:4, and 3:2 divider

errr....
can u be more specific
how to overclock it??

set the fsb to 250mhz...if it wont boot, set the memory to 320 (or 333)...if that doesnt work, set the memory to 266

the numbers 320 (or 333) and 266 are not the actual memory speeds, they are the memory dividers...fsb:mem...320 = 5:4, 266 = 3:2

Heh i have a silimar problem

a 2.8ghz p4C the multiplyer is 14.

IC7- 199$ model 875P mobo, Mushkin PC3500 ram.

i can get the fsb up to 225 and windows loads fine, if i take it up to 230 windows loads but eahter blue screens or just sits there trying to load.

i was thinking volts, but i wanted to ask someone who has done it what volt to use,

also i am really not sure what divider to use, i have it on fixed... im guessing i should change it!

play around with the memory dividers...put your fsb back to 200fsb and change the memory frequency settings to 532...slowly go up on the fsb till you find it unstable...then put your memory frequency to 266 and go up on the fsb till you find it unstable...

this will help you figure out if the cpu or the memory is the bottleneck...if you can go higher up on the fsb with 266 then your memory is the bottleneck, and vis versa with the 532

you can also feed the memory more voltage to increase stability,...the cpu you can increase up to 1.7v unless you want to play it safe on the cpu and stay at default, in my experience anything above 1.7v doesnt seem to benefit

hm, one thing i allways miss, could you post a table of the common dividers and what they equal to? eg 532= 1:2:3 etc?

...... fsb:mem

266 - 3:2
320 - 5:4
400 - 1:1
500 - 4:5
532 - 3:4
