    MCH Core that is too high or too low will cause boot loops and/or instability.
    If your system can't boot using your bios settings, it will usually reset some bios settings to "safe" default settings when it finally boots.

    I suggest that you try the following settings at 400MHz:
    System Memory Multiplier ---------: [2.00B] <--- try 2.00D if the B-memory strap fails
    Primary memory timings = 5-5-5-15
    tRFC -----------------------------: [72]
    Static tRead Value ---------------: [8] <--- for both memory channels, 7 will probably work once your system is stable
    note: if you are using the 2.00D memory multiplier, Static tRead Value (tRD) will need to be one step higher (looser).
    CPU Vcore --------- 1.35000 ------: [1.3625]
    CPU Termination --- 1.20 ---------: [1.24]
    MCH Core ---------- 1.10 ---------: [1.32] <--- 1.30 or 1.34 might be required
    ---> Some setups using your memory would only work with MCH Core = 1.05, but these were only using 2x2GB of memory.
    DRAM Voltage ------ 1.80 ---------: [2.12]

    Let us know which bios version you are using and your motherboard's revision number.
    Your E6550 should be able to overclock 45 - 50%.
    Let us know which stress test programs you are using and how long each test lasts.
    If there are any testing errors, post the error message details.

    I'll give those settings a shot tonight.

    It's in my first post, BIOS = F12 and it's a Rev1.0 board.

    I have yet to even get the system to boot into Windows with any overclocking. Every OC attempt results in that "soft boot" I described earlier (maybe "false boot" is a better description) and when it reboots itself again I get into Windows but I'm back at 2.33GHz. If I restart and go into the BIOS all my settings are still fixed but I get a red warning popup saying that my settings are bad.

    Get the system stable at stock FSB first.
    I recommend setting XMP manyually wether timings are left auto or manually. This is my opinion, other may think different.

    I figured I'd ask GSkill tech support what they'd suggest for memory settings so I posted in their forums, here is there response:

    CPU Host Clock Control - Enabled
    CPU Host Frequency - 333
    Performance Enhance - Standard
    System Memory Mulitplier - 3.20B
    DRAM Timing Selectable - Manual
    CAS Latency - 5
    tRCD - 5
    tRP - 5
    tRAS - 15

    Advanced Timing Control (submenu)
    tRRD - 4
    tWTR - 4
    tWR - 8
    tRFC - 80
    tRTP - 4
    Command Rate - 2

    MCH Core - 1.40V
    DRAM Voltage - 2.10V

    This motherboard will have no problem with 8GB DDR2-1100.

    Thank you
    GSKILL SUPPORT

    profJim, those settings you suggested didn't work. This time the CPU fan actually came on, but then the computer turned off, came up and did that boot where the CPU fan doesn't come on and then turns off again, then the computer came on and the post screen showed it back at 2.33. I played with the MCH Core in both directions (1.30 and 1.34), no dice. When I upped the RAM voltage to 2.12 I got the 23 beep salute.

    I put my system back to stock settings and ran 5 passes of IntelBurnTest on "Standard".

    Going to try "High" now.

    Many times IBT will have errors after 5 - 10 loops.
    Using Threads = 2 will be far more demanding with your C2D cpu. Setting the stress level to 2048 or 4096 will test more of your memory.
    With your setup, cpu core temperatures will probably be up to 60 - 65 (C) and this is safe when testing with IBT.

    Did you use any of Gskill's recommended bios settings?
    Please post your most recent stock bios settings and a screen-shot that shows:
    • Memset using the SPD and ">>" tabs
    • cpu-z CPU and Mainboard screens (several instances can be run at the same time)
    • EasyTune6 --> TUNER tab --> ADVANCE tab --> VOLTAGE tab (only the Voltage tab is needed)
    • CoreTemp screen [for your cpu's VID (Voltage ID)]

    WOW, I can't believe they suggest 1.4 MCH!! Sure you need more than normaly, but wow not that much

    I've seen several posts in the G.Skill forums where their techs want you to use MCH Core = 1.40 with 8GB of memory.
    Most setups in our forum with 8GB of G.Skill DDR2 1066 memory are stable with "only" ~ 1.32 volts.

    I've noticed that the G.Skill techs aren't aware of the posted bios settings where Fail-Safe defaults are used with the incorrect (i.e. non-optimized) clock drive values.

    Right! Or less sometimes as well.

    There is also some other settings that are hidden that are also incorrect when using Fail Safe, they should have a few boards I would imagine and be able to know this. But maybe not?
