lower latency, async vs. high latency, sync

[nauht]

For an Athlon 64 system, which is more preferable: Ram with lower latency running in async or high latency running in sync?

depends. there is NO hit from running async itself, just from the memory speed, which is negligable. your goal should be to get overall latency as low as you can, which is a function of timings and ram mhz. i use everest to find out the latency:

I see. The reason I asked is cuz I was debating whether I should get high FSB ram to run at 250mhz+ in 1:1 or stick with my OCZ Gold VX which right now is at 216mhz @ 2-3-3-8, 1T. I'm running the FSB at 260mhz with the 5:6 divider. I'm able to o/c my Venice to 2600mhz.

whatever gets you the highest cpu mhz

actually i noticed that mem freq and especially timings have almost no effect on memory latency in that test, CPU frequency does have a huge impact however. at least that's true in my P4 865PE system.

yeah, cpu mhz has a huge impact on latency for a64's too, even when you hold ram speed constant with a divider
