    Default Gigabyte X58a-3UDR help/advice please...

    Guys,

    Advice please… System: gigabyte X58A 3UDR, i7 920, 6gb DDR3 GSkill perfect Storm(cl9). I have the system up n running @3.66(183*20) without issue, running nice n cool with a Corsair H50. I simply changed the multiplier to 183, left everything else at auto. Now the question: Do I set the GSkill ram to its spec’s of DDR 2000 speed at 1.65v ,run the memory at auto of 1.5v with a lower latency spec?( no xmp selected) OR simply leave as is?(9-9-9-24 & 1.5v).

    Will I see a big benefit of running at DDR3 2000 speed over its current speed? I take it I can run the i7 at 183*20=3.66 as well as running the ram at DDR3 2000 spec? I openly admit noob status when it comes to the huge plethora of o/c options on the X58 chipset.

    Basically I’d like to max out the potential of my ram. Not looking to run higher than 3.66 or 3.80(speed step) sweet spot, although it will run 4.0 even stressed(prime95).

    Any help/advice greatly appreciated, have read a number of forum threads on this but never found the right answer or one I understood properly 

    Cheers…

    youll need to set your qpi voltage manually and ram voltage to 1.66 then test with memtest 4 try and tighten your timings you could try with 8-8-8-26-1T and test for errors try with qpi voltage at 1.320000 set cpu voltage to 1.20000 or try with normal setting,i can clock to 3.8ghz on 1.18750 cpu v.also your uncore freq will be twice what your ram multiplier is then add one or two too it so 8xram multi will be 17 or 18x uncore freq

    There is definetly a tangible performance difference between DDR3 1333 and DDR3 2000.

    But these differences can be minute or not there at all. use DDR3 2000 for benchmarking and showing off, generally low latencies matched with a reasonable speed e.g ddr3 1333 should get by quite easily.

    I agree, 2000Mhz is only for short uses. You should be able to run 1600-1800+ easy though if you want. Try that and if you need more help post back your full settings you are trying and we can help

    you can set your ram @1800mhz exactly with 3.8ghz 180x21bclk clocks, maybe one click higher on mem multi? will give you 1950mhz or something? remember to set uncore freq to twice mem multi then add one or two to it

    My board will never allow +1 uncore . I always have to use 8x mem X 2 for a 16x uncore.

    What do you mean? It wont boot, or you can't set it manually? If you cannot set it manually, do you have a ES CPU? If you are unsure about your CPU being ES or not please post a screenshot of CPU-z main tab.
