    I just noticed that your rev 1.0 mobo is running with the F8 bios.
    The most recent bios for your mobo is F10 and there might even be a newer beta bios.

    Where on earth did you get the inspiration for your garish multi-colored forum signature?

    Make sure that you have hard copy versions of your saved bios profiles.
    Your current stable bios profiles might need minor tweaking with a different bios version.
    Use QFlash to update the bios, not @BIOS.
    Set Keep DMI Data to Disabled before flashing.

    Don't use old BIOS profiles in new BIOS, not sure if that's what ProfJim meant or not, but it's not advised at all.

    Write down your settings in a template and go from there, using old profiles can cause all kinds of issues and one of the more often ones is super high Vcore on reboot after loading an old profile or incorrectly flashing BIOS (IE Flash, then not start with optimized and reboot)

    Hi guys,

    Not to worry, I flashed my BIOS to F10 using QFlash, the system rebooted itself, everything was reset.

    I then opened the BIOS and loaded Optimized defaults and tweaked the Memory settings, Latch, PCI-E, System Multiplier etc... didn't touch voltages, saved settings and rebooted the system again, the computer did a few more reboots on its own and then windows loaded fine. Only then I went into the BIOS and started upping the voltages again.

    Anyway, update, after roughly 2 weeks of tweaking and playing with my system, I'm pretty much at the same spot, I was able to stabilize 3.8GHz (10 LinX passes with 53.02 GFlops peak, 8 hours of Prime95 blend), but as I suspected I couldn't manage it with a Vcore lower than 1.4, here are my current F10 BIOS settings:

    Default settings for new setups that are not overclocked.

    As you can also see, I set the driving strength of both channels to 1066 like Jim suggested. at first I tried testing with VTT increased to 1.32-1.34, LinX passed but Prime95 still failed shortly after, tried increasing MCH Core to 1.3, LinX passed, Prime still failed, tried tweaking the references and it still didn't do the trick. So I decided only to increase VTT up by 1 notch and leave MCH at 1.26 and references untouched. As I thought, 2 clicks of Vcore stabilized it Prime ran straight for 8 hours with no errors and now my system appears to be fully stable at 3.8 GHz.

    CPU-Z shows a VID of 1.376 with 1.4 in the BIOS, this is already exceeding the maximum allowed by Intel and I know that in order to reach 4GHz I will need a Vcore of at least 1.4375-1.45 (1.41 in CPU-Z), which, I am not sure if I want to set.

    So several questions:

    1. Are the current voltages safe? Is something set too high?
    2. Should I try to move to 4 GHz with a Vcore of 1.4375? Is it safe?

    On a side note, just once in my life, just once, I'd like to get lucky and get a chip that can overclock like crazy... :sigh:

    Thanks :)

    Intel specs are 1.45v absolute max vcore.
    At the same FSB clock and CPU I need 2 clicks above 1.4vm which I "feel" safe with.
    In my attempts of 4GHz I had to set it over 1.46v which resilt at over 1.45 in CPU-Z but Prime95 still failed so I gave it up.

    You're still young, you may still find a golden chip one day.

    Hi Chike :)

    Correct, absolute max is 1.45, BUT, chip degradation will occur on voltages higher than 1.36 with 1.45 being the absolute max, so with CPU-Z showing me 1.376 I'm already in the danger zone...

    What should I do?

    We don't know the specifics for your recent reference volt settings:
    • Which reference settings were used (with VTT = 1.20) and what VTT setting was used after changing the reference volts?
    • How long did Prime95 run with each setting until an error occurred?
    • What was the FFT size that failed?
    • Have you performed any tests with CPU and MCH reference volts set to AUTO?

    Some find that using the B-memory strap is harder to get stable compared with using the D-memory strap. I suggest trying the 2.00B memory strap with tRD = 9. Up to about 460MHz, the 2.00B memory strap should be stable with tRD = 8 or 9. Using looser primary memory timings is advised until you reach your final overclock. I'd be tempted to try 5-5-4-12 timings with memory speeds 900 to about 980MHz.

    It's possible that changing DRAM voltage might help. Try 2.12 volts and 2.00 - 2.04 volts. My 2x2GB Mushkin 1066 memory was "happiest" with 2.00 - 2.02 volts up to 1100MHz.

    I don't recall seeing any Q9550 overclocks with MCH or CPU reference settings lower than the default 0.760 (AUTO) setting. You can try lower MCH reference settings (with VTT = 1.20) and then set VTT to the desired value. Note the Prime95 elapsed time and failing FFT value for each test to see if there is a pattern.

    Testing with MCH Clock Skew = 50, 100 or 150 might help with stability, but using this tweak usually is only needed with very high memory speed overclocks. I've seen very few overclocks with increasing CPU Clock Skew.

    There are several additional system tweaks that will improve system performance:
    Using 4K aligned partitions on my hard drive improved hard drive benchmark performance by 20 - 22%.
    Check post 44 in http://forums.tweaktown.com/gigabyte...tml#post383199.
    Performance Enhance = TURBO might be stable.

    I can relate to your frustration, my E6300 (R0) is not stable above 3.6GHz, no matter how much voltage I throw at it. I need to use just under 1.40 volts at 3.6GHz. My tweaking options on my P35 mobo are very limited compared to the options available with your EP45 mobo.

    I wouldn't mind CPU Vcore up to about 1.4250 volts when using a top notch cooling setup.
    Have you performed any gaming benchmarks with 3.6 and 3.8GHz. You might find that improvements at 4.0GHz are minimal compared with your current 3.8GHz settings.

    Hi Jim,

    Some answers for ya:

    1. Which reference settings were used (with VTT = 1.20) and what VTT setting was used after changing the reference volts?

    I tried MCH Ref 0.8 @ 1.2V and also 0.74 @ 1.2 V, with VTT set to 1.32-1.34 it didn't seem to make prime more stable.

    2. How long did Prime95 run with each setting until an error occurred?

    Prime95 ran roughly 15 minutes before it failed

    3. What was the FFT size that failed?

    I forgot to record that, but I can check the results file when I get home

    4. Have you performed any tests with CPU and MCH reference volts set to AUTO?

    Haven't tried leaving references on Auto with this FSB.

    Some find that using the B-memory strap is harder to get stable compared with using the D-memory strap. I suggest trying the 2.00B memory strap with tRD = 9.
    If the 2.00B SPD is tougher to get stable why should I set it? I'm currently using 2.00D

    Up to about 460MHz, the 2.00B memory strap should be stable with tRD = 8 or 9. Using looser primary memory timings is advised until you reach your final overclock. I'd be tempted to try 5-5-4-12 timings with memory speeds 900 to about 980MHz
    5-5-4-12 is looser? I always thought, the lower the numbers, the tighter the timings and speed is increased, am I wrong?

    Testing with MCH Clock Skew = 50, 100 or 150 might help with stability, but using this tweak usually is only needed with very high memory speed overclocks. I've seen very few overclocks with increasing CPU Clock Skew.
    I can try that if my next 4GHz test fails.

    Performance Enhance = TURBO might be stable.
    Everywhere I read says to leave this on Standard for stability, I can try using Turbo, but in the past when I tried it I would get instant BSODs...

    I wouldn't mind CPU Vcore up to about 1.4250 volts when using a top notch cooling setup.
    Have you performed any gaming benchmarks with 3.6 and 3.8GHz. You might find that improvements at 4.0GHz are minimal compared with your current 3.8GHz settings.
    1.425 refers to BIOS or CPU-Z? If I set 1.45 in BIOS I will get 1.41-1.42 in CPU-Z, do you think it's safe?
    Haven't tried any gaming benchmarks just yet, might have been a good idea to do so...

    IMPORTANT: Also some people told me that with a Quad CPU 450FSB is close to hitting the limit, but I've seen many people to 475 and also 500, what is the FSB wall for the Q9550 with my board?

    I don't mind upping the memory voltage to 2.12, maybe it will do the trick for 4 GHz, I'll try 1.425 Vcore with it, I assume VTT will need to go up to 1.34-1.36?

    Will a DDR2-1366 memory upgrade help in this case?
