    Default GA-EX58-UD4P Settings Question

    I have read the threads in this forum relating to the GA-EX58-UD4P. Based primarily upon the input of Lsdmeasap (gleaned from posts made to assist others), I arrived at the following settings for my GA-EX58-UD4P.

    The system runs quite well under normal operating conditions. It idles at 45C (70F ambient), and appears to be rock stable. It is predictably fast (4.116.4 MHz @ 21x).

    I have not, however, tried to stress it with Prime95, Intel Burn-in, etc. Before I do that, I'm soliciting comments on my settings (particularly those relating to the NB and the SB). I would like to know whether anything appears abnormal/out of line.

    OS: XP SP3 32-bit now, moving to Windows 7 64-bit

    Many thanks

    All looks fine to me, you may want to check with CPU-Tweaker and see what your actual tRFC is as I doubt it is 60. You may need that to be at least 74-84+, depending.

    Your NB Voltage may be fine in Auto (1.1) or maybe 1.14-1.2. 1.24 is a bit warm on the NB and often not needed, so just advising you of things to test out.

    ICH Core can also come down, as well as ICH I/O. I use more myself like you have, but I have 6 disks connected

    Lsdmeasp, belated thanks for your response.

    I've been doing some further testing (and tweaking ... primarily adjusting BCLK, and Vcore and QPI/VTT voltages), using Memtest 86+, Prime95, and IntelBurnTest. I've also moved to Win7 Ultimate, x64.

    The settings below are fully stable with Memtest (3+ hours), Prime95 (3+ hours) and IntelBurnTest (15 cycles on "high" (2048)). FWIW, my CPU temps reach 66C with Prime95, but only 60C with IntelBurnTest (70F ambient).

    I am also stable at 200 BCLK *IF and WHEN* running Memtest, Prime95 or IntelBurnTest, but I have random instability and crashing at 200 BCLK when the system is NOT loaded (i.e., no stress testing, and the CPU BCLK has been automatically cut to 12x, per CPU-Z). Specifically,

    • Random crashes in Firefox (which freeze the Explorer.exe UI), seemingly triggered by a mouse click. For example, when stopping a flash video; starting a flash video; and a "center mouse" click on a link to open the link in a new tab. FWIW, my mouse is a Microsoft Intellimouse Optical, using the drivers that ship w/Win7


    • Random system freezes ... often in the middle of the night ... some of which leave the hard drive activity light perpetually on (until the system is rebooted)

    Given the stability with Prime95 and IntelBurnTest (at 200 BCLK), I don't understand why the system should become unstable when it is UNstressed. ??? My sense is that my BIOS settings are not quite right (there are SO many options for the X58).

    I haven't done any testing with a BCLK above 200.

    Any thoughts?

    @SolidBladez

    Thanks for your response. I was aware of those tweaks to increase over-clockability, but I don't want to give up the features/benefits of C1E and EIST.

    The reason I suggested for those to be disabled is because you said you were having crashing or freezing when doing basic things (minimal load). I'm thinking that your CPU is throttling between multipliers and thus causing your system to freeze.

    That is why it is suggested to disable features when overclocking, period.

    I agree, if you want to overclock leaving these enabled is only going to cause you issues like you are seeing now. When the system downclocks the voltages are not correct anymore since you are not in auto and are overclocked, so everything gets messed up.

    I know it is a tough decision if you want to use these features, but really I advise against them with a overclock and wouldn't really know how to tell you to correct this because no one does it. Best I could advise would be to keep raising voltages until it stops doing so, but when speedstep kicks in I am not sure the voltages would change if you increased them or not, it may always go down to the same amount? Again I am not sure as I do not use this with overclocks or at all really, and I don't know anyone that does while overclocking either.

    I've been overclocking for 20+ years, and this is the first time that I've encountered stability under full load, and random instability (freezing) at idle. Not convinced that disabling C1E and EIST was the solution, I kept experimenting with the settings, and have now found voltages that result in complete system stability (with C1E and EIST still enabled, and 200 BCLK).

    Advanced Voltage Control:

    Load Line Calibration ........................ [Disabled]
    CPU Vcore ..................................... 1.31875
    QPI/VTT Voltage 1.150v ................... 1.28
    CPU PLL 1.800v .............................. 1.86

    >>>MCH/ICH
    PCIE 1.500v ................................... [Auto]
    QPI PLL 1.100v ............................... 1.30
    IOH Core 1.100v ............................. 1.16
    ICH I/O 1.500v ............................... [Auto]
    ICH Core 1.1v ................................ [Auto]

    >>>DRAM
    DRAM Voltage 1.500v ...................... 1.64

    Comments: My sense is that the key for achieving stability at idle was increasing the QPI PLL to 1.30. As part of the testing, I also disabled LLC. After disabling LLC, I had to increase Vcore to 1.31875 (from 1.29375) so that I could maintain the same voltage at idle (when the multiplier is throttled to x12) of 1.28 (as reported by CPU-Z); without this increase, I could no longer pass the IntelBurnTest. Disabling LLC allowed the "under load" reported voltage to drop as low as 1.248, which is fine with me so long as it is stable (and it is ... I ran 20 loops of the IntelBurnTest on "high" (2048), without issue ... together with 5 hours of Prime95).

    The voltages I'm using are still modest, and my temps are not high (65C on Prime 95 @ 70F ambient). Thus, I assume I could push the BCLK beyond 200 if I was so inclined. And I agree that if I want to go higher, at some point it will probably be helpful to disable C1E and EIST.

    If you happen to see any red flags in the current settings, please let me know.

    Nice to see you also tweak QPI PLL, often many users suggest this is not needed, Gigabyte even told me that as well and said Auto/1.10 would be fine.

    I find it IS Needed, and find it especially helpful at high Bclks. I use 1.24 for 200 Bclk, and 1.28-1.5 at 225-235+ Bclk

    At a QPI PLL of 1.28, I was able to go 3 days (and then had a random freeze at 5:37a, when the system was unattended); I then tried 1.26, and found that the system would freeze quickly (within an hour of boot); this obvious (adverse) effect on stability inspired me to move the OTHER direction from 1.28 and, at 1.30, it has been stable for 7+ days, up 24/7.
