Testing/Finding best ram timing

post #1 of 6
Thread Starter 
To test my ram going to use memtest86(think 4-5 hours is ok?)

Not sure what to use to test if my ram speed/timing have made an improvement however. I read in the sticky that
3) SiSoftware Sandra Memory Bandwidth Benchmark Test (establishes memory throughput).
So I guess I can use that and see which has the highest score?

Looking at http://www.xtremesystems.org/forums/...d.php?t=163668. Which would be better setup.
Timings: 5-4-3-12

2.0v - 482MHz (964MHz DDR)

Timings: 5-5-3-15
2.1v - 560MHz (1120MHz DDR)



I keep reading and keep finding different people saying different things. Some say intel use higher speed others saying balance.

My ram should be here in a couple hours, and hopefully this time it can pass memtest at stock specs

SuperPi is the quickest way to evaluate memory speed/latencie changes.

SiSoft Sandra latency tests is good for, well, latency measurements.

Don't expect a major change in latency (but do expect an improvement in bandwidth). Eg, 400MHz with fully tightened timings will have the same (or a slightly higher) latency as, say, 800Mhz with looser, but still tightened (after oc-ing to 800) timings.

Try 5-5-5-12 2.05v 4:5 (400FSB, 1000mhz ram)

5-5-5-12 @ 2.0V working so far!

Been two weeks since my pc turned on.. Since then I added a TRUE and 2 more case fans. Sadly my ambients have went through the roof. 78F in my house now, so my new cooling is showing about the same temps as my old cooling 53C max on small ffts after 30 min.

Anyway happy to be passing memtest86 w/o errors finally! Thank you all

Running SuperPi 1M works great to see differences in Cas vs. Bandwidth (more megahertz).
For quick trials, Memtest, especially #5, will tell you quickly if the memory will work at a given setting/speed. It will also show if the voltage is too low.
53c is not too hot for an E8400. If you get over 65c, you may want to look at it.
