CORSAIR TWINX1024-3200C2

[imported_rod]

I just built myself a nice athlon64 system, based around the 3200+ and an asus A8N-SLI deluxe motherboard. I also put 1 gB (2x512MB) of TWINX1024-3200C2 into it. The RAM is quoted as having stock timings of 2.5-3-3-6 on the corsair website, and I've seen reviews where it can be set to 2-2-2-5 without changing anything else.

I set the latency to "1T" in the bios, and assumed that this would make it run at it's best speed. But when I check it with CPU-Z, it says my latencies are 3-3-3-8!!! What's going on here??? At the very least, shouldn't they be running at 2.5-3-3-6!?

It is okay for me to change this manually in the bios, or could this make my system unbootable. One of my friends reckon that if you try to tighten up your timings and go too far, you will have to clear your bios and start again, until you get it right.

Any help people?...

Change them manually in the BIOS, it's perfectly safe... if it won't post, reset the CMOS with the jumper, or simply take out the battery for a minute. Try 2.5-3-3-6.. if that doesn't work, RMA for sure... if it does, keep that, or try 2-2-2-5, first with 2-3-3-, then 2-3-2, then 2-2-2.

around 2-2-2-7 is actually actually best for A64s

I thought lowest was always best...

dat's not tru... at 0, u'd have nothing..

Or would you have everything?...

I think Corsair may always set SPD to be higher than advertised speed. I had XMS2700-c2 that was advertised as PC2700 2-2-2 and when I looked at the SPD table it was 2-2-2 at 133 but at 166 it was 2.5-3-3. Now, it ran fine at the advertised speed. I always thought that was false advertising, though.

I set it to the advertised 2.5-3-3-6, and no problems so far. Havent tested it with Prime95 yet, but Seti@Home hasn't had any trouble, so i think Im fine now. On the weekend I might see if I can push it a bit further...

I'm running mine at 2-3-3-11. Passed memtest for 24hrs w/o an error.

I though it was advertised at Cas2 ?(maybe that's for Intel systems though. Damn fine print)

 

[imported_rod]

It is advertised as Cas2 (that's the "C2" at the end of it's name).

Hey, is memtest better than Prime95 for testing memory?

Thnx

Yeah, Memtest is better for ram. It's IS the best AFAIK.

I, and most others, use P95 for CPU & overall stability of an OC system.

I use memtest first, if ram passes for 24hrs you can be pretty confident a failure in P95 is due to CPU.

OK thanks. Its running fine at 2.5-3-3-6 now.

Hey, can you damage any of your components by tweaking your lateincies too far? Or do you just loose stability?

Thnx all.

just wont post / be stable as far as ram
too much voltage will fry the memory, but you have to get well into the 3.0V for that
