What's causes lockups when I try O.C.ing the Rampage II Extreme?

What's causes lockups when I try O.C.ing the Rampage II Extreme? I doesn't matter what utility I use, with exception of EPU-6 and the Turbo mode, it will adjust my setting read correctly and after a few minutes either lock up or restart on it's own. I've tried setting the XMP, I've tried running CPU Level Up, the only thing that running stable is the EPU-6 in Turbo or less.

My PC locks up when I Over Clock. Is it caused by the Mother Board, the PSU or Vista Ultimate 64?

Every power Supply calculator I can find I should be able to use less than 700 watts so I bought the Antec True 750. Could this cause it? How can I get my memory to run at it's native 1600? Memory runs fine at 1333.

And if anyone says I need a larger Power Supply, my only question would be is there a way to tell for sure that my 750 isn't enough? That it is the cause of the lock ups and restarts in Over Clock mode?

  1. It sounds like you're new to overclocking - keep in mind that the process involves lots of locking up, clearing the CMOS and starting over. I doubt there's anything wrong with your hardware.

    What BIOS version are you running? Your CPU requires ver. 1204 and I'd go on up to 1306. Be sure to update BIOS only from within the BIOS or floppy boot, not inside Windows. And make a note of your current version and obtain a copy of it.
    http://support.asus.com/cpusupport/cpusupport.aspx?SLanguage=en-us

    Your RAM needs at least 1.65V to run at 1600, maybe 1.7V. And with 6 modules you normally have to give it a little more voltage. Your motherboard only supports 1600 RAM with overclocking - so it's normal for it to run at 1333. And likely it's faster at that speed too - with the right CL settings.
  2. My Bios version is 1504 but it was updated through windows?

    The setting I had with 12GB 1600 Dominator.
    CPU level up =Auto
    Memory level up =Auto
    Ai Overclock Tuner =Auto
    CPU Ratio Setting =25.0
    CPU Configuration
    Dram Frequency =DDR3 =1600MHz
    UCLK Frequency =3200MHz
    DRAM Timing Control
    1st Information=9-9-9-24-6-88-12-8-30-0
    DRAM CAS# Latency = 8 DRAM Clock
    DRAM RAS# to CAS# Delay = 8 DRAM Clock
    DRAM RAS# PRE Time = 8 DRAM Clock
    DRAM RAS# Delay = 24 DRAM Clock
    DRAM RAS# Delay = AUTO
    DRAM REF Cycle Time = AUTO
    DRAM WRITE Recovery Time = AUTO
    DRAM READ to PRE Time = AUTO
    DRAM FOUR ACT WIN Time = AUTO
    DRAM Back-to-Back CAS# Delay = AUTO
    2nd Information : 1N-59-61-62
    DRAM Timing Mode = 1N
    DRAM Round Trip Latency on CHA = AUTO
    DRAM Round Trip Latency on CHB = AUTO
    DRAM Round Trip Latency on CHC = AUTO
    3rd Information : 6-6-18-10-10-10-10-7-6-4-7-7-4
    DRAM WRITE to READ Delay(DD) = AUTO
    EPU II Phase Control = Full Phase
    Load-Line Calibration = AUTO
    CPU Differential Amplitude = AUTO
    Extreme OV = Disabled
    CPU Voltage = AUTO
    CPU PLL Voltage = AUTO
    QPI/DRAM Core Voltage = 1.27500
    IOH Voltage = AUTO
    IOH PCIE Voltage = AUTO
    ICH Voltage = AUTO
    ICH PCIE Voltage = AUTO
    DRAM Bus Voltage = 1.65681
    Debug Mode = String


    OK, so that's it, where did I go wrong?
  3. The BIOS version is fine - just avoid updating it within Windows again.

    Does the system work right if only
    Dram Frequency =DDR3 =1600MHz
    and
    DRAM Bus Voltage = 1.65681
    and everything else set to Auto?

    If so, do that and reboot and test. Then change only the 9-9-9-24 to 8-8-8-24 and leave everything else at Auto.

    I'll have to test it tomorrow, I'm at work now.

    I did try the ASUS CPU level up ultility in windows and it caused lock ups and re-boots.
