ram timings

[nick1985]

my precharge delay(or something like that) is set to 5

everything else reads the number 2, just like it should

i was wondering whats the fastest setting for the precharge delay

Memory rated at 2-2-2-5 means the precharge delay should be 5. It's usually 5, 6, or 7. If your module doesn't specify that setting, then use 5 if it's stable, which it should be with any good memory if you're not overclocking and it's not "factory overclocked" memory that uses relaxed timings to reach higher speeds.

what is the fastest possible

right now im at 2 2 2 5

I'm pretty sure aggressive settings at 133MHz/133MHz with my XMS PC3200LL resulted in cas2-1-1-4-1T timings. Didn't bother running any benchmarks at that setting though, as it would've required much higher multiplier settings to run at equal speeds than my current setup.

You're not going to get any better than 2-2-2-5 using PC3200 at 400MHz. If you had the clock speed lower you might get better timings, but you'd probably have to drop it down to 266 to do that. At 333 you might get 2-2-2-4.

Has anyone ever done benchmarks where the only change was ram timings? Try them at "relaxed" timings and then at "aggressive" timings and see what the benefit trully is. I see all this talk of people always recommending certain timings, telling people they should get better ram because they can't reach certain timings, and explaining the theory behind why it will work better but no real world proof.

Kind of reminds me how people are always recommending AS3, treating it as if its god's gift to man, and explaining why theoretically its much better but then a comparison of many thermal compounds comes out and AS3 does 1ºC better in most cases and only 2ºC better in one case (when compared to regular silicon grease).
