Need help with BIOS - Overclock Intel E6750 (MSI P35 mb)

I'm having trouble understanding what settings that would be best for me when overclocking my Intel E6750, given my motherboard (MSI P35 NEO MS-7360) and BIOS.

System specs:
  • Fans: 2 x 92mm + 1 x 120mm (+STOCK CPU FAN, i.e. no extra cpu cooling)
  • PSU: 600W Fractal Design
  • CPU: Intel E6750 core 2 duo @ 2.66GHz (64kB primary memory cache, 4096kB secondary memory cache)
  • RAM: 4 x 1GB, see below:
  • Graphics card: ASUS GeForce 560Ti (GPU Freq. 900MHz, Memory Bandwidth 128 GB/s)
  • HDD: 400GB, 7200RPM (SAMSUNG HD403LJ)
  • Motherboard: MSI P35 Neo MS-7360 (Bus Clock: 333MHz)


    I've found and tried two setups, but I would like another opinion. My BIOS seems to be different than the ones used in E6750 clock settings threads that I've found, so that's another reason for my asking even though there are answers out there already. This is what my BIOS' advanced settings menu looks like:



    My gathered info from different forum has given me the settings below so far, but I need your help with the red-marked ones:

    D.O.T: Disabled
    EIST: Disabled
    FSB Freq: 375
    (Adjusted CPU Freq): 3000
    ---
    Advanced DRAM Conf. -> Configure DRAM Timing by SPD: Disabled (Need help with individual values here)
    FSB/memory Ratio: 1:1? (Auto shows as 5:6 in cpu-z) I have seen both 1:1 and Auto as recommended value
    (Adj. DDR Mem. Freq): ... not sure what this would be with 1:1 ratio.
    ---
    Adj. PCIE Freq.: 100
    Auto Disable DIMM/PCI Freq.: No idea
    ---
    Voltages default
    ---
    Spread Spectrum: Disabled

    So a little help with the red parts and let me know if any of the other values should be set to something else.
    And if I end up with an unstable setup, do I then raise the CPU voltage as the first step?

    Couldn't edit for some reason, I wanted to add this:
  • BIOS: American Megatrends Inc. V1.3 08/09/2007
    December 15, 2012 1:04:48 PM

    I went ahead and tried myself with this config:
    D.O.T: Disabled
    EIST: Disabled
    FSB Freq: 400
    CPU multiplier: 8
    (Adjusted CPU Freq): 3200
    ---
    Advanced DRAM Conf. -> Configure DRAM Timing by SPD: Enabled (6-6-6-15 I think)
    FSB/memory Ratio: 1:1
    (Adj. DDR Mem. Freq): 800
    ---
    Adj. PCIE Freq.: 100
    Auto Disable DIMM/PCI Freq.: Enabled
    ---
    Voltages default
    ---
    Spread Spectrum: Disabled

    I tried 32M SUPER_PI and it was done 2min faster than before. I might try Orthos later if I find settings for that program.

    UPDATE: That didn't worka t all, Battlefield 3 crashed after a minute or so, before I spawned even.

    Can someone help me understand why that is? Should I raise the voltage on some component?

    I also forgot to mention that I use Windows 7 Professional 64 bit.
