    Re: First Time Overclocker On Deck

    i7-860

    The overclock shouldn't be crashing as it was stable when I tested it before messing with the RAM.

    Re: First Time Overclocker On Deck

    you haven't mentioned whether you have raised the vcore. bump it and see if the stability returns.

    your memory should run fine at cas 8@1.65 or 1.64v

    Right now I have a few questions.

    In looking at your manual again I believe the answer to that is at the bottom of page 39. In intel speak I think they are calling FSB >> "BCLK" Frequency and used with the "CPU Clock Ratio" is how you get your final CPU Frequency.

    For overclocking I would set the memory freq at 1600MHz.

    No answer there

    VDMM is your memory voltage

    My current clock settings run, but half my cores fail HyperPi 8m.
    For Voltages look at the bottom of page 45 of the manual (at least the one I found on line!)

    I agree with ud in wondering where all the intel dudes are!!

    Re: First Time Overclocker On Deck

    I'll keep cracking at this till I have a stable RAM OC. Then I'll start hitting the CPU.

    About the BCLK, I do know that it changes the frequency of the CPU, but as far as I know, it doesn't affect the RAM at all.

    This page has images of the overclocking section of my BIOS, from here you can see what I see when I enter the BIOS.

    The Memory Frequency (two options down from BCLK) only offers three option. 1333, 1500, 1800. I don't have 1600 available, even though this board is supposed to support this memory, which is really strange.

    Re: First Time Overclocker On Deck

    your making me learn intel stuff!

    from what i gather, the reason 1600 isn't listed is it's not supported by the cpu. in order to run 1600, you need to oc the whole system.

    http://www.thinkcomputers.org/intel-...cessor-review/

    Memory Supported: Dual-channel unbuffered DDR3-1,333MHz

    there is a chart at the bottom.

    Re: First Time Overclocker On Deck

    I got a stable overclock of 8-8-8-24 on my RAM by increasing the voltage to 1.66.

    I learned that to increase my RAM frequency, I need to increase my BCLK before it will go up (I guess it has to do with the integration of the memory buffers and such onto the i7 CPUs)

    I'll start heading for 4.0 later this week.

    Just in case you all didn't know, I got my stable 4.0 overclock and posted in the Super PI hall.

    Re: First Time Overclocker On Deck

    Listing what I learned.

    1. The BCLK controls the frequency of both the CPU and RAM.
    2. Multipliers affect how much the BCLK affects the CPU and RAM.
    3. Voltages are stupid and I still can't figure out how to make them do what I want.

    Re: First Time Overclocker On Deck

    Gaining an understanding of 2 of the big three isn't bad!! Intel seems to have their methology and nominclature so non-users have an issue. Not sure how to get some intel guys to help you out, maybe list some questions in the mobo section form your intel mobo?

    Re: First Time Overclocker On Deck

    I guess I should let people know is that I finally got my OC completely stable.

    i7-860 @ 3.36Ghz, 3.52 w/Turbo Boost, Clock 160Mhz, Multiplier x21
    Gigabyte GA-P55A-UD4P motherboard
    Corsair Dominators, CMD4GX3M2A1600C8, 1600Mhz, Multiplier x10, Voltage 1.64, 8-8-8-24

    This information is for reference only, and not to be construed as an absolute truth for all setups of this type.

    Think of them as like a Wish List: you may get what you want, but I wouldn't rely on it. And don't assume higher is always better, because sometimes it isn't.
