*Warning newbie question contained here*

I've read posts about CAS 2-2-2 and 3-3-3 (or something like that)

I've gathered that it has something to do with RAM. Anyone care to enlighten me please

well basically cas 2-2-2 takes to cycles of your memory to take and recieve the data. cas 3-3-3 take 3 cycles to do it. Now this is all basic info, it get complicated like the cas to ras delay but im not sure about those and i dont wanna give u wrong info.

Ok so basically you're resetting the cycle length of the ram in the bios so that it runs faster.

I still don't know all about it, but there is some good info here, along with other info on bios terminology...
