    Default Diferent Memory Timings in Dual Channel

    Hi Guys,

    Here´s is a nb question. I have 2x512mb 400mhz running in dual channel, but their timings are different. One is 2.5 - 3 - 3 - 7, the other is 3 - 4 - 4 - 8, something like this. The problem is that the BIOS recognizes them as 333mhz. When i take one off and check in BIOS again, it recognizes as 400mhz.

    I tried do set both to the same timings, but i get a blank screen at startup. The bios, automatically set it to the lowest ram timing.

    Any ideias?

    Tks in advance!

    Specs:
    MSI NEO2 865PE
    P4 2.8E HT
    2x512mb 400mhz have no idea the manufactors.

    If you want to overclock, then get yourself a decent set of matched PC3200 ram and that would help alot. If you are running stock speeds, you would be hard pressed to notice the difference between DDR333 and DDR400 speeds. If they are running DDR333 in dual channel mode, your best bet is to leave them that way.

    It sounds like you have a faulty set, or a pair that aren't matched. When they are set the same(faster timings) and you get the black screen, the slower stick obviously cannot handle the speed. Either find the tightest timings your slower stick can handle, or do as casecutter suggested and get a matched set.
