  • The 6GB installed, 4GB in bios problem?

    Mobo: ASUS P6TD Deluxe
    RAM: G.Skill NQ (G Skill F3-12800CL9-2GBNQ)
    CPU: i7 930
    PSU: Antec Quattro 1000



    First of all, i'd like to say thanks for your time.

    I'm having the issue that it seems thousands of people re having where only 4 GB of ram is detected on a COLD boot. When one leaves it as 4GB detected, the system is very unstable and will get a blue screen < 5 minutes.

    This doesn't happen just on 1600 for me, but also on 1066 or 1333.

    I must of read this page 50 times: http://i4memory.com/ramdetect/

    Things i've done so far:
    - Updated the bios to the newest version
    - Mucked around with voltages over and over again (AI Tweaker posted below)
    - Reseated CPU
    - Rotated each ram stick
    - ON morning, tested each ramstick cold in A1 to see if they would post, they did.
    - Performed memtest -- crashed instantly when opening it. (rebooted) Should be noted, i've tried an ubuntu live CD memtest and a memtest downloaded and burned. Both had the same result.

    After a full days work on the PC, i decided to boot up memtest, and it did proceed to run this time (without crashing), however it's close to 3:30 am and i need some sleep.


    For the night, i've set the AI Tweaker to the following.

      If your system has issues on a cold boot, and then does not after it is reset, then you surely have the cold boot problem. Send the memory in for new replacements and that should solve the problem.
