    You lied when your bios template showed LLC = Enabled, shame on you

    Are you lying about tRFC too?
    tRFC ------------------- 52 ---------- : [54]

    I'd rather see this on AUTO while you're trying to o/c higher. Normally this setting should be OK with your memory.
    When you've reached your final o/c, we will optimize your memory timings.

    If Prime95 Blend fails within 15 minutes, it is during a large FFT test, and this points toward a memory issue, rather than a cpu issue.

    Test with the following settings with 455MHz FSB
    Code:
    CPU Vcore --------------- 1.25000V ---- : 1.28750 (2 clicks higher than 9 x 450) 
    CPU Termination --------- 1.200V ----- : 1.22 <--- with cpu vcore = 1.28750, up to 1.24 is OK
    CPU PLL ----------------- 1.500V ----- : 1.55 <--- if needed, up to 1.59 is safe
    CPU Reference ----------- 0.760V ----- : [Auto]
    
    MCH/ICH
    MCH Core ---------------- 1.100V ------- : 1.22 <--- 1.24 might be needed
    MCH Reference ----------- 0.800V ------- : [0.74] <--- this is OK
    MCH/DRAM Ref ------------ 0.900V ------- : [Auto]
    ICH I/O ----------------- 1.500V ------- : 1.57
    ICH Core ---------------- 1.100V ------- : 1.20
    The next time you lie in your bios settings, you'll be mercilessly beaten with a wet noodle

    Hi Deafty,

    Did you try playing with the references yet? If you have ET6 installed, you can adjust them without rebooting (just make sure you press "set").
    I have dabbled with MCH refs but have not done full test phases. I do have ET6 thanks for the tip.
    I will be going down this road but not just quite yet..
    -----
    I've been getting Mtest and IBt passes at higher fsb.

    Most notable is 465x9 with 2 clicks up on the Vcore with MCh 0.70 (VTT @1.24)
    Failed Prime 95. (memory related)

    Question Forgetting about the overclock what is a better VTT? closer to 0.800??

    So forwards we go ,(thanks Professor)

    1. Changing:
    tRFC ------------------- 52 ---------- : [54] Now Auto

    Will start with clicks Vcore and try Prime
    Then make my first MCH Core adjustment
    I'm thinking that will get me over.

    then work may way through:

    CPU Vcore --------------- 1.25000V ---- : 1.28750 (2 clicks higher than 9 x 450)
    CPU Termination --------- 1.200V ----- : 1.22 <--- with cpu vcore = 1.28750, up to 1.24 is OK
    CPU PLL ----------------- 1.500V ----- : 1.55 <--- if needed, up to 1.59 is safe
    CPU Reference ----------- 0.760V ----- : [Auto]

    MCH/ICH
    MCH Core ---------------- 1.100V ------- : 1.22 <--- 1.24 might be needed
    MCH Reference ----------- 0.800V ------- : [0.74] <--- this is OK
    MCH/DRAM Ref ------------ 0.900V ------- : [Auto]
    ICH I/O ----------------- 1.500V ------- : 1.57
    ICH Core ---------------- 1.100V ------- : 1.20

    Ok off to the testing with my little pieces of paper (I gotta get me an xtra PC)

    Thanks guys..

    Question Forgetting about the overclock what is a better VTT? closer to 0.800??
    I'm confused.
    The lowest stable VTT setting is your goal. Increasing VTT is often needed to stabilize a system, especially with higher overclocks.
    "Closer to 0.800" - are you talking about a modified MCH (or CPU) Reference value?

    When VTT is set with a higher value, the manually set reference volts will auto adjust with higher values displayed in the bios AFTER you have reset VTT from 1.20 to the desired 1.XX value. It will be less confusing for you to focus on the manually set reference value, such as 0.74, 0.72, ...., 0.68 because the auto adjusted reference value displayed in the bios will vary with the modified VTT setting.

    I hope this is clear.

    Yes very clear,. sorry badly written question.

    Earlier back at 445x9 I noticed reducing VTT didn't effect stability but was needed to get there in the first place.

    I've been testing..
    I'll post results after this,.

    Yesterday I was unable to pass prime 95. The whole time I'm thinking MCH core, MCH core,MCH...you get the idea.
    Now after your recent post of test codes. It included MCH CORE increase. So guess what at 455x9 I increased it and passed Prime95 8 minute testx10. Some other adjustments were needed but that will be detailed later.

    As my time is somewhat limited than Jakes,..
    I have been playing around at effectively 2-3 different FSB zones (if you will) As in 4GHz 4.1Ghz and 4.2Ghz. And running Prime overnight working my way up the FSB's
    The idea is to have the lower of these with higher stability improvement.

    So whilst working through higher FSB tests I ran my 445x9 all the way through Mtest, IBT and including Prime 95 8min testx10 "blend " with 3 hrs stock blend test followed by 8 hrs stock blend test. I'm happy with this for now. Probably needs fine tuning or dialing in as you put it. Next up is 455 Prime test long.

    My recent activity was to achieve a pass on Mtest and IBT 2048Mb with 467x9 and prime.
    So worked my up and through the FSb's where I hit the what I think to be the MCH core Hurdle.
    However I have passed both now, but am back at the same issue with passing prime95 from yesterday and it fails early on. In regards to your comment of this is usually related to the memory, I now feel that increasing the MCH core passed 1.24 is not wise.

    Please,. what are the effects of CPU PLL adjustments.?
    And where would you focus your efforts?

    Details to come,.. but please comment..
    Thanks

    No I haven't,. I defintely will, what am I looking for when/if it fails.

    Not customised as I don't what to customise

    But ran small FFT default test,..
    and failed early.

    Try enabling LLC
    Customize 8k: click small FFT, click customize, put 8 in both min and max FFT, run.

    HI CHIKE
    Crap,. I haven't seen your posts from 17 hrs ago!!!

    I've passed Prime 95 blend 8min testsx10 on 455x9 higher Vcore,higher VTT and higher MCHcore as above (previous 2-3 posts.)

    I'm currently on 467x9
    with the following:

    VCore 1.300V proved better in IBt test.
    VVT @1.24
    MCH Core @1.24
    MCH Ref @0.74 (with Vtt@1.24,.mch is,..)

    Passed Mtest 5x#5test
    Passed IBT (3 times) 2048 MB auto
    FAILED Prime 95 custom blend 8min test x10 (early fail)

    Same scenario as at 455x9.

    Now testing your custom FFT test
    First, try to run customized small FFT with min/max FFT 8k. If it fails you got a winner.
    Being 8K FFT try higher vcore.
    Leaving Vcore alone from above settings.
    TEST RESULT: 1test 1min worker 1
    FAIL
    +1Vcore Fail
    +2Vcore Fail
    +3Vcore Fail fatal error.


    From what I read the CPU clock skew is the one that will need to be changed, MCH clock skew muc hless or not at all.
    Try 50-200ps CPU clock skew.
    Will try later,..trying now.

    Thanks.
