wut is a good ram latency?

[trance565]

hey guys, i was just wondering what a good RAM latency is, and what it would change if i had better.
aparently my current ram lat is 2.5-3-3-3
is that any good? just wondering for future ups to my comp

a good ram latency (just guessing) is probably something like 2-2-2-2 (im not sure if they have 1's) but yea.

what exactly is ram latency?

2-2-2-5 is the lowest stock settings that i have seen.

Isn't the lowest made by Cosair or Kingston?

Yeah I have some corsair xtra low latency and it runs at 2-2-2-5 pretty much as low as it gets.

Gotta get some of that in DDR2 if i can

I think ddr2's latencys are higher

THe cas latency is the time it takes the memory to process the data. It is a physical aspect of the memory just like the frequency. Just like you cannot make the memory physical frequency faster, you cannot make the latency lower.
So the lower the latency, the faster the memory will react.
Changing from DDR to DDR2 will only work if the motherboard is adapted to it. For example a PC3200 has a frequency of 400 Mhz. If your motherboard FSB can be overclocked and it has the slots to take PC4000 for example, then you can overclock your motherboard, but make sure you have adequate cooling.
Note: DDR and DDR2 don't have the same number of pins!
