Some DDR-RAM questions (I did a search).

I had a little sheet around here at one point. I seem to remember that the Corsair XMS at PC-3200 or PC-3500 on an A7N8X etc, with a 266Mhz FSB, was way overkill, and even had stability issues.

What was the formula for what speed RAM you'd need again? i.e.

PC-2700 good to xxx
PC-3000
PC-3200
PC-3500

What were they, and what was the way to figure it out, I can't find it

Also, I'm ordering A7N8X Deluxe w/ a XP1700+ TbredA core, going to o/c. Will the 2700 be just ducky right? (Corsair XMS).

Thanks!
Dave

i dunno of any formula, i just use good ol memory
although you might be able to do a regression on it lol....

anywas
pc2700=166
pc3000=185
pc3200=200
pc3500=215

those are approximations...

it seems a factor of 16 will give you an approximate speed rating...

if you plan to get a high fsb (which you should) id get around 3000..

Just divide by 16 or by 8 to get the DDR clock

for single channel DDR remember its MHz * 2 (DDR) * 8 bytes (64 bit SDRAM) = x.xxx GB/sec ex... 200MHz * 2 * 8 bytes = 3.2 GB/sec
