    Default help with ram freq and timings

    hi i am owner of a gigabyte ex 58 ud5 with f9 bios,cpu i7 920 ,ram ocz3p2000lv6gk 9-9-9-30 1,65 volt ,and 5850.

    all i want is to set the ram freq at 1600 and good timings(no cpu oc yet).i tryed to do that with system memory multiplier from bios.ok worked but the timings were high.. 10 ,8 ,8 ,22 (at auto. i didn't change them cause i was afraid possible damage) i thought it will be lower cause at 2000 gives 9-9-9-30... maybe i am wrong.

    any help with that?

    tell me if i have to post more info about hardware

    sorry but i am new to oc :)

    With bclk at 133, set the memory multiplier to 12 (12x133=1600). Manually set the timings to 8-8-8-24 and leave the rest on auto. You won't hurt anything.

    dont leave ram voltage on auto though as it will overvolt,set it to 1.66 which is 1.64 actual voltage

    i did it.8 8 8 24 at 1.64 ...cpu-z says that at 1333 ram can give 8 8 8 19 trc 31 at 1.5 volt.
    maybe ram can give better timings than 8 8 8 24 at 1600 1.64 volt ...what do you think?

    btw should i change trc too?i don't know what is it...
    and thanks for your quick reply.

    Well you bought DDR3 2000 ram to run it at 1333 would be a waste of $$. 19 or 24 isn't going to make any noticeable difference except perhaps in benchmarks. But I would try lower volts maybe it will run at 1.5v at 8-8-8-24. You could also try setting command rate to 1T which will improve memory bandwidth. Can you post a screenshot of the CPU-Z memory SPD tab? If your ram has an XMP profile for DDR3 2000 perhaps we can actually get it running there.

    I don't see an XMP profile for DDR3 2000, just the four JEDEC specs. Are you able to scroll over in the CPU-Z SPD tab? No XMP? I would think if they are selling it as DDR3 2000 it would have XMP. If not you will have to set everything manually, which is going to be hit or miss. Try setting memory multi to 14, Uncore multi to 28, Vdimm to 1.66, QPI to ~1.3-1.4, timings to 9-9-9-30, auto the rest. To be honest if you are happy with 1600 I would stay there.
