    How do I find what the timing numbers are for the memory that came in my Clevo p151? When buying more memory it has not only the speed (1333), but the timing numbers.

    I have no idea how robust the Sager's BIOS is, but you should be able to interpret it there.

    Failing that, CPUID should be able to tell you. I think it's HW Monitor that recites your DIMM statistics.

    You can use HWinfo or CPU-Z to check your ram timings.

    you will fail to find anything useful in the bios as I recall.

    Not sure about 1333 but the timings for 1600mhz are 11-11-11-28. You can get RAM with the same size and speed but with CL9 for $50 shipped so better to buy your own in that scenario

    what are ram timings and what does it affect? its different from the clock speed?

    timings are different from clock speed. Basically, the higher the timings, the faster the clock speed must be to increase performance. Lower timings are better.

    ex. DDR3 has higher timings than DDR2 and therefore must run at faster clock speed to outperform DDR2.

    A bit of a tangent here - HWInfo is reporting 3 different timings in my laptop :

    CL - 9 RCD - 9 RP - 9 RAS - 24
    CL - 7 RCD - 7 RP - 7 RAS - 20
    CL - 6 RCD - 6 RP - 6 RAS - 15

    Is that normal for triple channel memory?

    my guess is that those are the timings depending on the clock speed, but they all seem rather low for a laptop. 9-9-9-24 would be 1333MHz i think! meaning the others would be 1066Mhz and then possibly 800Mhz. As you can tell I'm not sure about that though ;P

    Hmmm. the x7200 doesn't allow any BIOS changes for this. I wonder if the Corsair RAM allows the mobo to drop to a more optimized timing.

    In any case, there's not complaint on my end in regards to memory.

    Thx.
