    Default Maxing out with an EP45-UD3P, Q9650 and 8GB RAM

    Hi guys,

    I'm about stumped at trying to find out what I top out at with my Q9650 as I never bothered to tinker with it until I bought an SSD for it a few days ago and repurposed my other pc so I could fool around with this one.

    I bought the Q9650 used from someone local who managed to get 450x9 @ 1.32v with a Rampage Formula and stability tested through LinX. At the moment, I have only successfully ran through IBT on maximum stress x5 @ 425x9. Details below:

    I think I can tighten up those settings (passed an IBT run right now with lower voltages) but at least I seem to have a starting point. I've had no problems loading onto the desktop at 450x9 and higher but the system locks up in IBT after 1-2 passes with the very rare BSOD and reboot depending on the changes to the vcore, reference, pll, termination, etc..

    I'm not sure if the amount of RAM (4x2GB) or the RAM itself (DDR2-1100 5-5-5-15 1.9v) is a limiting factor as I haven't run Memtest yet but running 2 sticks didn't seem to make a difference. Temperatures seem OK (62c load) but higher than what I expected.

    I've read as much as I could find on here and OCN but I'm going to need a guiding hand as I feel there's room to improve

    Thoughts?

    Please run 3 IBT(v2.53) loops with stress level high and post you Flops.

    Please attach also a CPU-Z text report (CPU-Z -> About tab -> Save Report (.TXT)).

    Might be too much for the memory with 8GB installed.

    I would like to see lower VTT and MCH Core too if possible, I never needed more than 1.18v MCH Core at 450 and ram at 1080.

    Set PLL one step up, 450MHz FSB, CPU ratio 8.5 SMM 2.40B (leave latch auto) Static tRead Value 9 on both channels (we'll lower to 8 later). See if you can pass 3 INT runs with stress level high and what Flops you get.

    Personally I use IBT to confirm I have enough vcore, the rest of stability I leav o Prime95.

    EDIT: Set Performance Enhance to standard
    EDIT2: I'd also leave all advanced memory timings auto.

    Thank you for the response, Chike.

    No go in IBT. No lockup just the critical error popup. I played around with the settings with similiar results.

    Attechments as their name suggest need to be attached, if not attached they are deleted from the server after few minutes.
    You mean IBT reports failue r is it windows error?
    Can I have the settings in question?

    Hi Bonka, hey I have a Q9550 on the same board but revision 1.1. Let me do some checking on my settings. I would think you wouldn't need that much vcore nor cpu termination. but who knows. I see a few thinks off hand I would change but I'll get back to you on that...

    CPU-Z Dump Q9650.txt

    Attachments should be fixed now.

    It was an instability window pop-up within IBT.

    I adjusted the vcore and mch 1-2 notches from your settings yielded the same pop-up. If I start adjusting more settings like the vtt as well I get lockups or boot looping.


    EDIT:
    Thanks Conners. It doesn't seem like the CPU has hit a ceiling and I'm hoping it's not the RAM.

    A couple of things I would try off hand is to put your memory to 2.40B, set (G)MCH Frequency Latch to auto. Tell me more about your memory such as standard voltage and timings. Also with 8 GB memory you may have to change some things. especially if the wern't a matched set. Also a screen shot of CPUZ would be better for me at least lolz

    One (or actually 2) of the essential settings for stability are the references. Almost everyone must change MCH Reference, some need to change CPU Reference as well.
    Try the following:
    Lower VTT(CPU Termination) (but not less than 1.2v) to the point memtest86+ fail test #5.
    Now try to adjust MCH Reference until you reach stability or the point that yield less errors.
    Try adjusting CPU Reference. Lower VTT more and repeat untill change makes no difference.

    Try to adjust Clock Skews. Only one of them need to be adjusted if at all, begin with CPU Clock Skew, and if it make things worse, set it back to zero and try MCH Clock Skew, try 50-200ps for each one of them.

    To keep track of changes made t reference we make all changes with VTT set to 1.2v, as follows:
    1. Set VTT to 1.2v
    2. adjust the reference to desired value
    3. Set VTT back to its original value.

    Begin with 0.76v of both references @ 1.2v VTT, than set VTT to the first value below 1.3v that fail memtest86+ test #5.
    for MCH reference try lower values first, 0.74-0.70 (it's rare to need lower than .70)
    For the CPU reference try higher values first (1-3 steps higher than the default 0.76)
    After you find memtest86+ stable settings continue to IBT/Prime95.
    VTT may need to be set 1-2 clicks above the value that was memtest86+ stable.

    I would start this procedure with CPU ratio 8(x450) then 8.5.

    This is the RAM I'm running: DDR2-1100 5-5-5-15 1.8-1.9v. They are not the matched set, just 2 sets of 2x2GB but I haven't come across any info with issues running 2 non-matched sets.
    G.SKILL-Products

    If you really need it I'll grab a CPU screenie. Too many restarts in the last few days!

    I would start this procedure with CPU ratio 8(x450) then 8.5.
    Memtest didn't show any errors after several passes at multiplier 8, 8.5 and 9, 2.40b strap, vcore 1.3, vtt 1.2, pll 1.57, CPU reference .785, MCH core 1.22, MCH reference .800. I had to bump up the vcore to 1.35 and references to .800 and .840 to get into IBT. It passed IBT on high (2048) x10 but would fail using very high (4096).

    Clock Skew changes either locked up the desktop, no post or BSOD so I'm going to leave these alone for now.

    I'm going to run through your settings methodically again as I didn't keep track of the settings used to find a pattern.

    Are you talking about MCH reference only or both MCH and CPU reference.
    You may need to increase VTT. try in steps up to 1.28v.
    What were GFlops on high stress level?
