    Both references. CPU Ref .800/MCH Ref .840.

    I'll have to get back to you on the Gflops (didn't output and didn't remember :().

    Scaling your previouse GFlops at 4.05GHz they need to be 56+, if less try a 2 clicks higher vcore.
    Run a few hours Prime95 blend, customize it to use all the memory available (check in Task Manager's Performance tab).
    The size of failing/crashing FFT is very important.
    Check the "Round off checking" under advanced menu.
    What are max core temps with IBT? Maybe we can beat that Rampage by a 100MHz or so.

    Ok just running a cycle now. GFlops are ~55.2 on high.

    Are low GFlops an indication of low vcore? From all the changes they've gone as low as 23 (on maximum).

    For Prime95, is there a need to also check off the option above it, SUM(INPUTS) error checking?

    As of now from my notes, 1.35 vcore, 1.2 vtt, 1.57 pll, .785 cpu ref, 1.3 mch core, .800 mch ref has gotten me the furthest in IBT, giving me an instability popup error on the 2nd run and without locking up the desktop. I didn't note the GFlops but they might've been rather low.


    EDIT:
    IBT just finished 1 run with .815 cpu ref/.840 mch ref and the GFlops were 36.9451 before locking up :/

    If everything else is correct than low GFlops mean more vcore.
    Any change that cause lower GFlops is bad, regardless if IBT fail crash or even pass.

    To do things faster you can use EasyTune for minor changes, then press the "set" round blue button.
    All refernces are shown as their values at 1.2v VTT, no need to change VTT while changing the references in ET6.
    Have you tried lower MCH refernce?
    After finding the best possible reference values, try to increase VTT, tweaking references may not be enough.

    I am not even sure we need the round off checking, torture tests may enforce it anyway, but I have ran tests with SUM error checking and have never had it happen.

    Bonka, have you ever tested your set up with stock settings to see if it was stable? Also what I meant about you 8 gigs memory is they aren't guaranteed to work as advertised since all four aren't a matched set. Would you mind posting your stock bios settings?

    EDIT: Yes make sure round off checking is checked in P95.

    Might read this thread lots of good information on references and how CPU term affects them besides alot of other good stuff. It's how we got mine @ 500 FSB stable. But I chose 3.92 because it varied verry little off of stock settings.

    @Conners,
    I think I accidently ran IBT on the default settings and it passed though that meant that the RAM was underclocked. Do want my fail-safe defaults?

    I'm reading the link you provided right now, thanks :)

    I'm still tinkering with the settings. As of now I can do several passes in IBT on custom 6144 but still no go on max. Prime95 blend on max memory failed a couple of minutes in on core 0, followed by core 1 about an hour later. I'm re-running blend now after an adjustment and so far so good about 25 minutes in. Temperatures are a concern however, been topping out at 77c in IBT.

    Not fail safe Optimized but it's not necessary for now I was just thinking I may want to start from scratch..lol You may want to update to the lates bios which is FFb I think. What are your current bios settings? Maybe I can suggest some changes... Also I wouldn't run P95 Blend till the last test for stability. Run Small FFT 1st using the chart below adjust the settings one at a time and test as per below. Once stable goto Large FFT and do th same. Later we may be able to lower some voltages.

    Here's the method to my madness.

    Test with IBT or P95 Heres the method I use to get it stable.

    1. Set to your known stable settings or optimized defaults. <---for you I guess where your at.

    2. Start with raising vcore one click at a time and test.
    2a. If doing so is stable for two clicks stop and go to 3 if not goto 2b.
    2b. Lower to best stable setting.

    3. Raise CPU term one click at a time and test.
    3a. If doing so is stable for two clicks stop and go to 4 if not goto 3b.
    3b. Lower to best stable setting.

    4. Raise CPU PLL one click at a time and test.
    4a. If doing so is stable for two clicks stop and go to 5 if not goto 4b.
    4b. Lower to best stable setting.

    5. Raise CPU term one click at a time and test.
    5a. If doing so is stable for two clicks stop and go to 6 if not goto 5b.
    5b. Lower to best stable setting.

    6. Raise CPU Reference one click at a time and test.
    6a. If doing so is stable for two clicks stop and go to 7 if not goto 6b.
    6b. Lower to best stable setting.

    7. Raise MCH Core one click at a time and test.
    7a. If doing so is stable for two clicks stop and go to 8 if not goto 7b.
    7b. Lower to best stable setting. (note since you use 8 GB ram you may need to go down 2 clicks instead of up)

    8. Raise MCH Reference one click at a time and test.
    8a. If doing so is stable for two clicks stop and go to 9 if not goto 8b.
    8b. Lower to best stable setting.

    9. Raise ICH I/O one click at a time and test.
    9a. If doing so is stable for two clicks stop and go to 10 if not goto 9b.
    9b. Lower to best stable setting.

    10. Raise ICH Core one click at a time and test.
    10a. If doing so is stable for two clicks stop and go to 11 if not goto 10b.
    10b. Lower to best stable setting.
    and this from Psycho101

    Small FFT
    This test uses data that fits completely into your CPU's level 2 cache, it stresses the processor intensely but does not stress the RAM or the link between the RAM and the processor. It will error out because of:
    Not enough vCore
    Possibly low CPU Termination (VTT)
    Possibly low/high CPU ref
    Possibly low PLL (clock generator) voltage

    Large FFT
    This test uses large "pieces" of data that require information to be moved in and out of RAM quite intensely to constantly feed the processor. The data in these calculations doesn't fit completely in CPU onboard cache, so the work load on the MCH and RAM is huge. It will error out because of:
    Not enough vDIMM (RAM voltage)
    Not enough (and rarely too much) MCH core voltage
    Incorrect MCH ref voltage
    Unstable memory timings (includes both main timings ie 5-5-5-15, and also tRead and tRFC.
    Only fails because of processor when vCore is waaaaaay too low!

    Blend
    This alternates between small and large data sets, and although it is a useful "last test" when run for say 24 hours after you believe you have everything dialed in and it passes Large and Small seperately, it's confusing for fault finding.
    If Blend fails it could be for any reason mentioned for small FFT and large FFT leaving you with no indication what to do to stablise the system.

    The FE is gone from GB site, there must be a good reason for it.
    Static tRead Vallue(tRD) auto is kinda junkish, see what you get with MaxxMEM² - PreView.

    This is with tRD 8

    Just running through your methodology, Conners :)

    Just updated to FFb. Appreciate the endorsement Chike and Conner

    Chike, you're right about the tRD. Auto was rubbish.

    Auto:
    Memory-Copy: 9,729 MByte/sec.
    Memory-Read: 8,076 Mbyte/sec.
    Memory-Write: 9,495 Mbyte/sec.

    Reached memory score: 8.79 GB/sec.

    Memory-Latency: 68.5 ns

    Reached latency score: 68.5 ns

    ---

    tRD 8:
    Memory-Copy: 10,127 MByte/sec.
    Memory-Read: 9,126 Mbyte/sec.
    Memory-Write: 9,573 Mbyte/sec.

    Reached memory score: 9.35 GB/sec.

    Memory-Latency: 58.9 ns

    Reached latency score: 58.9 ns
