    Right, I'm looking into following dkillone's/Lannigan's legendary BIOS mod throttle fix By looking into getting G74s with fully populated memory banks running at their true speed. After ordering from a reseller with 4x 4GB 1600s I'm a little annoyed that I could have saved money by opting for the 1333s instead - so, let's look at fixing this. Let's open up AMIBCP and look at the RAM config...



    As default, both failsafe and optimal values are set to 'Auto', I'm figuring if I override the optimal column to a setting of 1600, save and then flash, that this will inform the system the max speed for the memory to run safely would be 1600.

    I really need someone with experience in BIOS mods to go over this and make sure there isn't anything else I'm missing from the other settings before I flash and potentially cause harm. My only concern is that it must be grabbing the 'Auto' value of 1333mhz when the slots are fully populated from somewhere, and the same for the post-1333 'true' values (1600 or 1866) when only two slots are being used, and I'd like to know where.

    "Are all slots populated? No? Run at top speed. Yes? OK, run at 1333."

    I can't find it, and I don't want it to conflict with me telling the BIOS optimal settings are 1600. If this automation overrides then fine, the mod simply won't take effect, if it conflicts and bricks, then I'm in a world of hurt. ><

    Regards,
    Dave.

    Sounds like a scary plan, but might actually work if you use those DDR-3 1600 RAMs. I think that option is to tell the RAM to run "only" at 1600MHz, so if you are going to put in DDR3 1066/1333 RAMs you might not see it POST.

    Also, I forgot to mention I'm using the i7-2760QM, a CPU capable of running the RAM.

    The only thing holding back the 1600 is the BIOS.

    Is it already running at 1600MHz when you inserted those RAMs you ordered from the reseller?

    I've not received it yet, but I doubt it will, as I've heard of others with the same processor, same model and the same problem.

    It should be here by tuesday.
