Corsair TWINX2048-3200C2?

[BroadbandGamer]

Right now I'm running 2.5-3-3-6 1T. Do you guys think I can tweak these timings a little?

Thanks,

What are the manufacturing specs??? You may be able to force cas 2....trcd of 3 is already pretty low and most average sticks will not run 2 100% stably on AMD64 systems....

According to Corsair, the timing I'm running are the rated speeds. But for some reason if I set my memory to auto in the BIOS is runs at 3-3-3-8 2T. CPUz shows SPD as 3-3-3-8. This same memory in my old K8N Neo2 Plat set to auto would run at 3-3-3-6 1T.

SPD is set to JEDEC specs for compatibility reasons, IIRC.

JEDEC also applies for wide standards.

You specifically, for being a more advanced user, will be able to alter the timings according to choice (system specs matter). However, risk system instability, or in contrast, get nice results. Pure CAS 2 might be hard if they're not the more expensive XMS versions, and I'm not talking about the extra LED addons.

Some people are running these memory modules without a hitch at 2-3-3-6 timings. I'm getting a Corsair TWINX2048-3200C2PT set myself to go with my X2 4400+ setup.

I intend to overclock the CPU by about 220MHz over the stock 2200MHz speed (220x11 = 2420MHz). But I want to preserve 1:1 ratio on the RAM. Will these modules hold good at 220MHz @2-3-3-6?

Has anybody tried overclocking these modules?

I'm running mine stock too.

I can't see the difference between 2-2-2-11 and 2.5-3-3-6, so I haven't bothered trying to tweak the timings.

If i'm not mistaken, these timings really aren't important in A64 systems. And i have the same A8N SLI premium with the same memory and auto settings are 8333

 

[Bona Fide]

Yeah timings don't matter as much in an AMD system. Still...it's better to run DDR400 at 2-2-2 than DDR500 at 4-4-4, I think.

I contacted Corsair about that. For some unknown reason, they told me that they set the SPD chip to report "3-3-3-8", but the real rated timings are 2.5-3-3-6 for AMD systems and 2-3-3-6 for Intel systems. You might as well change the CAS setting to 2.5 and grab the extra (imperceptible) performance you purchased.

No and yes respectively.

Stable at 200/2-3-3-6-1T, not stable at 220/2-3-3-6-1T but fine at 220/2.5-3-3-6-1T for me on stock voltage.

Given I couldn't find anything that displayed any difference between 2 and 2.5 at 200 other than synthetic benchmarks ( and even then negligibly ) I'm not sure that is any real concern.

Delighted to hear that. Thanks.
