Corsair XMS CMX256A-2700C2 have a question

what does this this mean ram module 2.5-3-3, its off of corsair's web page

http://www.corsairmicro.com/xms/xms3000perf.html

can anyone explain what this means, thanks to any future help

-C

It's the "Memory Timing"

Now for what each # means exactly, and what it controls I don't know.

You'll have to look further for that info.

The lower the #'s the faster the memory runs. (the better)
2-2-2 is faster than 2.5-2-2

2.5 cas 3 ras 3 tras.
You can find what those mean here: http://www.rojakpot.com/Speed_Demonz/BIOS_Guide/BIOS_Guide_Index.htm

To make it easy lower numbers are better.
