Ram timings

[nelson1]

Will I be able to tell a difference, specifically like SuperPi or any other testing the difference between 4-4-4-12, 4-4-4-11(or 10, 9 ect....)?

There will be a difference, I'm not sure if it will be a great deal or even noticable, but your Memory scores in benchmarks such as EVEREST will increase a bit

oh okay, I was curious because I overclocked my E4300 and my ram timings at 4-4-4-12 and 5-5-5-12 were the same in SuperPi. 1mb in 19secs and 2mb in 41 secs. I didn't see much of a difference.

The only difference you'll see is in the tests. You really wont notice any speed difference in normal day to day use.

okie, now its time for orthos, wish me luck

from 4-4-4-12 to 4-4-4-11 is so small that it probably won't even show in the tests.
Now between 4-4-4-12 and 5-5-5-12 there should be some difference, but super-pi might not be the best program available to test ram, it's more of a cpu thing. (though ram still does have an effect too)

I think looser timings have less of an effect on DDR2 than DDR. I remember seeing benchmarks on tighter timings versus higher mhz, and the tighter timings achieved lower scores. I think it was on Anandtech sometime back.

thanks for the replies guys.

right now I am testing a E6300 system, right now its at 3.33ghz. 476*7
The memory is at 5-5-5-12. Now I had to put 1.5volts to the cpu, it wouldn't pass orthos unless I put it at 1.5. The temp hovered around 39-41.

I'm going to 3.5ghz but I am going to have to watch my temp real carefully.

Super Pi really benefits from tight timings and fast RAM speed. So if you could run 550mhz (1100mhz effective) @ 4-4-4-8, it would be better.

I would probably have to put more juice into my ram than. Probably 2.25 or 2.3. I have a pair of G-Skill rams, it can run a real tight timings at 4-4-3-5 but the farther I push it the looser I have to set it. I'll try 4-4-4-12 first than the tRas to 8.
