    Default Need help overclocking P55-UD3R from 2.67GHZ back to 3.2GHZ.

    I just put new RAM in my system, and lost my overclock settings =(
    I was running at 3.2 GHZ on my I5.

    I just put in CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMZ8GX3M2A1600C8, and used the XMP Profile 1 in my bios. But It dumped me back to default 2.67 GHZ. Can someone assist me in what I need to change to get back to 3.2GHZ in my bios? Thanks.

    What do you mean by "dumped me back", the pc start up with default settings or your actual BIOS OC settings changed all back to default?

    I dont think the bios went back to default, but putting this new ram in, and using the XMP profile (where before I did not use that) put me back at default speed.
    The previous memory I had was DDR3-2000, this is 1600

    If you are using XMP you still need to adjust SMM to set thr right frequency. Assuming you set 160MHz BCLK SMM should be 10, the default with XMP is 12 which will result in 1920.

    Ok So I want to make sure the BCLK is set to 160, SMM is at 10, and my multiplier at 16?

    For 3.2GHz you need 20, but it's good to try 16 to see that memory settings are not a problem.
