ram timings?

post #1 of 5
Thread Starter 

what do you think?
my stock ram timings are 2.5-4-4-8-12-2T
with my ram timings loosened, I can hit 260Mhz. what is a better gain? tighter timings like this, or higher clocks with looser timings?
260Mhz
2.5-6-6-10-12-2T

How much looser? I would put my money on 260, but it would be close I'd say.

This is going to be a long post, but it will allow you to fully understand the situation.

Unless you use data-intensive programs (ie, programs that transfer many GB's of data per second), high bandwidth - high speed - is not required (the PC number [eg, PC4000] is how many MB's can, theoretically, be transferred per second).

Low latency (latency is the time to FIND the data) will benefit you the most. But, tight timings DOES NOT equal low latency. 3-3-3-8 at 250MHz is LEAGUES better than 2-2-2-5 at 100MHz in terms of latency. Not a great example, but you get the idea.

Your best use of time is to simply leave memory speed as it is, and tighten each timing, one at a time, and using Memtest (there are 2 version of Memtest, and this is better than the other - it picks out errors the other version misses) to test for stability. You don't want programs or your O/S to become corrupt, do you.

If you have the time, you can achieve a slightly lower latency (and I mean slight) by overclocking your memory to it's maximum speed, and I would recommend against increasing voltage. You will have to loosen timings as you get faster. Then when the memory has hit it's highest stable speed, tighten all the timings.
