When I change ram timings...

My original timings were 2.5-3-3-7-2T, and I changed them to 2.5-3-3-5-1T and my score went from 4665 to 4622. Before I do or say anything stupid, which is faster, 1T or 2T, and how much does ram affect 3DMark scores?
 
Heh, well I am running DDR500...

I'll change my timings back, run 3Dmark YET AGAIN, and post results.
 
Hmm, I ran EVEREST with both timings, there's a 1ns difference 🙂.

My ram is PC4000, but it shows on EVEREST as 3200...
 
Set it to your settings, went up to 4638. Jeez why can't I hit 4660's anymore? Scores aren't supposed to go DOWN! 😛

EDIT: Wait nvm, forgot to change half the timings, it was set to 2-3-3-10 instead 😛

That score is 1 percent off if you do the math. That is variable. Heat, Cache on the CPU, voltage fluctuating..etc..
 
lol I know, I'm being a perfectionist, this is my first time working with stuff like this so I wanna get to know everything and ABSORB IT ALL!!

Anyway I set to 2-2-2-10-T1, crashed, set to 2-3-3-7-T1 and running 47.7ns (I think this is latency?), which beats a 2-2-2-5 with the same specs, which is pretty cool. Now I'm gonna run some stuff to make sure it stays.

My point was that your hardware will never be perfect within one percent under you circumstances. What you are trying to do is overkill.

Anybody else would say the same, even anandtech. Timings on a A64 mean very little unless the timings had to be completely loose for a large overclock. In that case however you are better off buying RAM at a suited rating like PC3500 to sustain the overclock. If you are able to run 2.5 T1 latencies, which came rated stock for your ram, you are not going to see a noticeable performance gain going any higher.
 
TRCD and TRP always have to be the same, right? EVEREST gave me slower tests with the new TRAS, who knows?
