  • F3-14900cl9-4gbxl failing memtest86+ test number 5

    Ram is set at default, registering 1600.
    I ran memtest86 and ram fails at test step 5.
    If I try to OC the cpu anything past 4.0 the WIN7 64 will not boot or I get a bad check sum error.
    I have re-flashed the bios, 1.2. Done this 3 times.
    I have ramped up voltages but it does not help.
    Basically any manual CPU oc past cpu mult 234 / nb x10 @ 2340 (which is apprx 3.3, stock proc speed) sys will not boot.
    Faulty ram module (s). I know the ram is not on this mb QVL but.......
    Any thoughts would be appreciated.

    sorry RJ

    did you raising the DRAM voltage or manually set as 1.5v?
