memory

Hi, when i look at memory, a spec i see is something like 2-2-2-5. what is this?
are high numbers better than low numbers? and what is CL? i see CL values of 2, 2.5, 3. is higher better? I'm getting the ASUS A8N32-SLI delux and i'm trying to figure out which DDR400 memory to get from Corsair. any recomendations?

  1. 2-2-2-5 are the timings. CL stands for CAS Latency. If you want a more in depth explanation of RAM timings, go here:

    http://en.wikipedia.org/wiki/RAM_latency

    Your primary concern should always be what the CL is (also the first number in a timing specification like 2-3-2-5). Latencies range from 2 to 4 (maybe 5?). The lower the better.

    If you're going to get RAM from Corsair, this is what I would get:

    If you're not planning to overclock, it's great memory. I have this exact set of DIMMs. You can get it here for $198:

  2. which one would you use if you are planning to overclock?
  3. Those are Samsung TCCD chips, very good for overclocking.
  4. You can loosen the timings on the memory I posted and get some good OC out of it. But if you really want to push the envelope, look into PC3500 or PC4000 memory. :-)

  5. Those Corsair run at 2-2-2-5 up to about 220mhz, and any memory running at PC 4000 would have same looser timings as the Corsair at that speed.
  6. True. But overclockers don't usually give a crap about timings. Otherwise all this PC4000 CAS3 crap wouldn't sell! :-D

  7. well the ASUS A8N32-SLI delux can only take as high as ddr400.
    i'll probably put in an Athlon 64 x2 4200+. i doubt that has the venice core.

  8. Uhhh no. That motherboard can handle much higher speed RAM. It's just not officially supported.

    I have an x2 4200+... me luvs it.
