Aopen i975Xa-YDG – What speed RAM do I need for a good O/C?

[smilingcrow]

I’m not clear how the RAM dividers work for this board. If I get lucky and can push a T2500 to a FSB of 240, what will the memory clock be running at? I’m assuming that the dividers aren’t flexible enough to allow me to use PC2-5300 with that FSB. I’m basically trying to determine what’s the slowest RAM I can get away with for now.

3:5 = 240/3 * 5 = 80*5 = 400Mhz RAM
3:4 = 240/4 * 5 = 300Mhz
1:1 = 240Mhz

etc

good oc?

generally the cpu is gonna be limiting in this one not the ram

i use crucial balistix running @ DDR2 600mhz speed 3-3-3-4

the lowest it let me run it at was at DDR2 533 and my FSB was 225

Thanks Kiwi, I get it now; I’ll stick with PC2-5300.
