Can't get i7 920 to overclock

Hi All,

Here is my Setup:

ECS X58B-A3 SLI
Intel Core i7 920 CPU
6 x 2GB Apacer DDR3 1333mhz (12gb Total)
1Tb Seagate HDD
2x Nvidia 250 GTX in sli

ThermalTake Element V case
ThermalTake Frio Cooler
ThermalTake Toughpower XT 650w Modular PSU

Here is my problem:

I know now the that ECS is not the best OC Mobo but i can't get it to overclock one bit.

I just bought the mobo and don't want to go out and buy another one, so can anyone please help me to get it to 3.6 + Ghz?

I tried various settings in M.I.B III but everytime i save it it won't turn post and i have to do a reset to get it back to normal.

Thanks in advance.

  1. Temp is around 30C.

    Fans can be set faster manually if i need to. Only Running round 1800RPM's (Max is 2700Rpm)
  2. Okay, Got it running at 3.2 GHz.

    I now get random Stop: 0x00000124

    Here is my current bios config.

    Advanced Setup:

    Thermal Management – Disabled
    TM Status – TM2 (greyed out)
    Limit CPUID MaxVal – Disabled
    Enhanced Halt (C1E) – Disabled
    Intel XD Bit – Enabled
    Intel VT – Disabled
    Intel EIST – Disabled
    Intel (R) HT Technology – Enabled
    Intel VT-d – Disabled
    APIC Mode – Enabled

    MIB III (MB Intelligent BIOS III) Settings:

    Performance Level – Standard
    Dram Frequency – 1333MHz
    Uncore ratio – 2933MHz
    Configure DRAM Timing by SPD – Disabled
    SPD eXtreme Memory Profile – Standard
    DRAM tCL – 8
    DRAM tRCD – 8
    DRAM tRP – 8
    DRAM tRAS – 20
    DRAM tRFC – 59
    DRAM Command Rate – CMD 2T
    CPU Over-clocking Func – Enabled
    CPU Over-Clocking Freq – 160
    PCIE Over-Clocking Func – Disabled
    Ratio CMOS Setting – 20
    Auto Detect DIMM/PCI clk – Enabled
    QPI Freq. Auto detect – Auto (Currently running at 6.400GT)
    Spread Spectrum – Enabled
    CPU Voltage – Disabled
    IOH Voltage – Disabled
    CPU VVT Voltage - +0.143v
    DIMM Voltage – Disabled
    SB Voltage - Disabled


    Please advise as what to watch out for and what I could try and change to make it stable.

    I also need to keep my RAM at MAX 1333MHz, how can I ensure it stays at that?

    Thanks again.
  3. Hello Again,

    Looks like it's stable now at 3.2GHz.

    Enabled Configure DRAM Timing by SPD, and added more volts to CPU VVT.
    I also Added IOH Volts.

    My RAM only reconised 8GB so i added a touch of DIMM Voltage and now it runs all Modules.

    Now Time for the next step.
  4. Darn it - my recommendation was going to be get rid of the Extreme RAM profile and select SPD - glad it worked

    Memory volt needs to be 1.65

    The issue you are facing is as you clock up BCLK you are clocking up your Uncore which overclocks RAM and QPI - so you need to down clock those devices with the ratios.

    Sounds like you are off to a good start...
  5. Got it stable at 3.3GHz now with the setup below.

    Advanced Setup:

    Thermal Management – Disabled
    TM Status – TM2 (greyed out)
    Limit CPUID MaxVal – Disabled
    Enhanced Halt (C1E) – Disabled
    Intel XD Bit – Enabled
    Intel VT – Disabled
    Intel EIST – Disabled
    Intel (R) HT Technology – Enabled
    Intel VT-d – Disabled
    APIC Mode – Enabled

    MIB III (MB Intelligent BIOS III) Settings:

    Performance Level – Standard
    Dram Frequency – 1333MHz
    Uncore ratio – 2933MHz
    Configure DRAM Timing by SPD – Enabled
    CPU Over-clocking Func – Enabled
    CPU Over-Clocking Freq – 165
    PCIE Over-Clocking Func – Disabled
    Ratio CMOS Setting – 20
    Auto Detect DIMM/PCI clk – Enabled
    QPI Freq. Auto detect – Auto (Currently running at 6.400GT)
    Spread Spectrum – Disabled
    CPU Voltage – Disabled
    IOH Voltage – +0.088v
    CPU VVT Voltage - +0.299v
    DIMM Voltage – +0.105v
    SB Voltage - Disabled

    Problem now is I can't clock this anymore, i don't find the Ratio's to down clock the RAM and QPI in the bios.
    I really want this to run at atleased 3.6GHz, so any help would be much welcome.

    Great Forum, and great help, thanx Guys.
  6. Help please?
  7. Looks like you need to add voltage to the cpu.

    "CPU Voltage – Disabled " Enable that and give it a few bumps. Don't go wild though.
  8. I will try just that tonight.

    Will my Dram stay @ 1333Mhz with it set to 1333?

    If i set my CPU Over-Clocking Freq from 165 to 166 it won't even post.
