    Now you've included too much information.
    what do you suggest to get this #$% thing over your self imposed the IBT 10 pass hurdle?
    Bad boy!! Now I've increased my "self imposed hurdle" to 15 loops just for you.
    Your IBT failures show that only running 5 tests isn't adequate for a quick initial stress test. Running 15 or 20 loops would take longer and possibly generate errors.
    My opinion is that 10 loops is sufficient for a quick preliminary stress test.
    Are you using Threads = 2 with your E6750 while testing with IBT?
    With this setting, my E6550 IBT times are reduced, GFLOPS scores are significantly higher, and vcore temperatures are 2 - 3 (C) higher.

    Your IBT temperatures are quite reasonable. It's normal for the maximum core temperatures to rise to 60 - 65 degrees (C) while testing an overclocked system with IBT or LinX. Prime95 or OCCT tests are usually about 10 (C) lower. I would start to be concerned if temperatures rose to 70 (C) or higher.

    While you're overclocking, it's normal to have to raise vcore voltages slightly as you o/c higher. At some point, you'll have to raise the voltage significantly higher even when you're trying for a moderately higher o/c.

    From what I've seen, when needed, dual core processors respond best when MCH Reference voltages are lowered from the default value.
    When needed, quad core processors require higher MCH Reference voltages when attempting "extreme" overclocks, generally when trying for 4.0GHz or higher overclocks.

    Your stated goal is to run your system at 3.60GHz.
    I tested my system using:
    1) 459MHz x 7 (3.21GHz) using 2.40B memory multiplier, tRD = 8 for 1101MHz with 5-5-5-15 primary memory timings.
    2) 492MHz x 7 (3.44GHz) using 2.00D memory multiplier, tRD = 9 for 982MHz with 5-5-4-12 primary memory timings.
    The 492MHz setup was about 3 - 4% faster.

    The optimal setup for your system might be:
    435MHz x 8 (3.48GHz) using 2.00B memory multiplier, tRD = 8 for 870MHz with 4-4-4-10 (or 12) primary memory timings.
    Your desired 450MHz x 8 (3.60GHz) with looser primary memory timings might under perform the 435MHz setup.
    With 435MHz settings, you might not need to manually set reference volt settings or clock skew settings.

    My preference is to o/c my system to the highest possible performance level using "reasonable" voltage settings.
    I'm not a fan of having LLC enabled. Your E6750 "should" be able to o/c to 3.8 - 3.9GHz, but at this point you would probably require CPU Vcore voltage close to 1.42 volts. I wouldn't have a problem using 1.4 volts for everyday operation if my cpu vcore temperatures where reasonable.

    ProfJim, Just curious what I screwed up this time. I changed the tRD from 10 to 8 (5-5-5-15) and the system would not even post. The default in the BIOS is 9 versus the 8 that is the default in the Q9550 system. If that means anything. I had to clear the CMOS to get it to startup! I changed it to AUTO and all is well. What am I missing. I think I was here once before with the Q9550 system?

    Using the 2.00B or 2.40B memory multipliers with the EP45-UD3P, tRD = 8 is usually stable from about 420MHz to 460MHz.
    Using 2.00D usually requires tRD = 9, one step looser. MCH Core = 1.28 might be needed.

    The main differences in your settings that I see are:
    Load Line Calibration = Enabled.
    Reference volt settings are manually set.

    What are the most recent settings for:
    CPU Host Frequency?
    System Memory Multiplier?
    Primary memory timings?

    I would wait to tweak tRD (Static tRead Value) until you've reached your final overclock settings.
    For some reason your setup seems to be a lot more difficult to overclock than other similar systems.
    From what I've seen with other C2D overclocks, reference volt settings are set to AUTO, and don't require manual settings until you're trying for very high overclocks.
    Your system might require CPU Vcore = 1.37500 or 1.38125 volts with LLC disabled.

    The "default" tRD value displayed in your bios is often the most recently used setting, not the default setting.

    Try tRD 9 then, 8 may be too tight for your current memory amount and chosen voltages. There really is no BIOS Default, you can always ignore what you see on the left as it may or may not be used by the system at any given point.

    Here are the latest settings:
    CPU Host Frequency 440
    System Memory Multiplier 2.00B
    Primary Memory Timings 5-5-5-15 EVERYTHING else AUTO.

    Reference settings are at Auto meaning I put the VTT back to 1.20V and set the Reference voltages to the default and let the BIOS increment as the VTT was increased to 1.32V.

    I know it's probably overvolted at this point but it runs IBT 10 passes and is going for 15 passes! But don't understand why tRD 8 works on Q9550 machine and not on the E6750 system. Same MB and same Memory?

    Default Re: Normal Voltage for E6750

    Well they use 2 different CPU's is why they will not run the same.

    You say same memory, was it bought at the same exact time? If not they could both be using different IC Chips even if they are the same model, making them not the same. So that could be another explanation for it all.

    Looks like you are making progress though, keep at it!

    Default Re: Normal Voltage for E6750

    ProfJim and others,
    I'm still trying to get this thing to run 2.40B and it won't - period. I set everything to AUTO and the system will not post so it was not the tRD of 8. I did find a new setting that appeared with the Mushkin memory "Extreme Memory Profile" that was set to AUTO. I looked at the Q9550 BIOS setting and it was DISABLED. I thought I had the magic bullet so I DISABLED it and set the memory at 2.40B (FSB 400) and tried to reboot. The system came back with a black screen with the horrible "CPU ID 06FF CPU Clock 0.0" criptic message. After much fooling around clearing CMOS etc. I finally got the thing to let me in the BIOS and restore a good saved BIOS. For some reason the Gigabyte default startup splash screen would not let me in the BIOS with the DEL key. I had to use the TAB key and then it went into the normal posting stuff and acknowledged the DEL key to get into the BIOS. Any idea on what the heck is going on? Should "Extreme Memory Profile" be DISABLED on any system?

    Personally I recommend using XMP manually([Profile 1]) even if you set timings manually, there is no harm in it, unless you want to use stock settings, which it then should be disabled.

    B straps often will not work above 400 FSB, try using D.

    Everyone has their own opinion, I suggest against XMP as it is meant for those who don't know and don't set anything. Enabling and using it, but changing settings is the same as having it disabled.

    If settings timings manually why should you be against it?
    tRC is not present in GB BIOS and is sometimes different in EPP, one good reason i see to enable it.
