    Default Are CPU clocking and Memory multipliers independent of each other?

    I've researched so much stuff lately that now I'm about to have a siezure, and I'm still confused. With the I7 using memory differently, I don't want to rely on info that might not apply. So if someone could help me out, you'd be doing a humanitarian deed.

    Can I up the memory multiplier and voltage on the sticks and manually change timing in BIOS to take advantage of it's ratings without changing the CPU clock or voltage?

    The new machine is going to be used as a DAW, not heavy gaming or benchmark testing. I just want to be maximize the memory's ability. I don't plan to OC the CPU because I can't find a good CPU cooler that will fit into the 4U rack case I used!

    Details:
    - Intel I7 on a Gigabyte EX-58-UDP4 mobo.
    - Ver. F6 bios that I flashed yesterday no problems.
    - Triple channel 6 gig OCX DDR3 1600 PC3 12800 8-8-8-24 1.65 volts

    The bios settings are now set to auto and the memory is showing 7-7-7-16, 1066 on all three channels at 1.5 v.

    SO.... with the ability to change the mulitiplier field to 12, it shows the memory speed changing to 1600. Can I then just do that, set the timings for each channel to 8-8-8-24 and adjust the voltage to 1.64 or lower?

    Thanks for helping reduce brain pain!

    Yes, they are seperate. But you will need to change a few other things as well. You will need to make your uncore Freq 2x Memory Multi (2x12=24) and set Your timings and voltages for the ram of course. Then be sure QPI Freq is on 36, then you will need to find and set a Proper QPI Voltage. If your sticks have XMP, you can enable that and have a look at what it suggests and maybe start there, but it is all CPU Dependent on hwo much your cpu will need it may be more or less then the XMP sets

    Then you should be good to go once you find the proper QPI Voltage

    L, thank you. Not sure how to find QPI voltage though, so I'll do some digging. How critical is it?

    It is very critical. You find what is stable for you by setting it high first, then slowly back it down until you start failing tests then raise it back up a few. Start at 1.30-1.35 or so and see if you need more or not, likely not

    Hi L,

    Thanks for replying again on this topic. My main interest and goal for the computer I built is as a highly-functioning Digital Audio Workstation. I'm not really into ongoing tweaking, so I want to find a good, safe set of overall settings that will maximize the hardware I have. Is there one single, reliable document or source of information for this stuff so that I can stop wasting your time?

    Thanks again,
    Vic

    Well, no not yet really. There is a few guides that are simple/partial for Overclocking X58 but they are not full/complete guides as the hardware is so new. So I would not know where to advise you to look for a non overclock setup.

    I can help you if you like, if you would like some suggested settings for a non overclock setup let me know and give me the settings you are using now and I can advise back >>>

    This is Just a template I use to ask people their settings, pay no attention to the numbers in it, replace with yours

    Thanks L again. We're talking on several threads, so I'll stay over on the Gigabyte section with this and get back to you.

    OK, ya I had thought so. I loose track sometimes as I do not always remember to look at who is posting when I am very busy and behind.

    Ya, I did post you some heatsinks on a thread somewhere yesterday as well as some settings I think maybe?

    Anyway, I will see you in the Gigabyte section then
