    Default (x48T-DQ6)I can't get my FSB past 400mhz or my memory past 1600mhz

    I need some help badly. I recently purchased this memory CORSAIR DOMINATOR 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 15000) and I installed only 2 of the 3 sticks onto the pink slots of my mobo. I need some guidance on getting these sticks past 1600mhz. Preferrably 1866mhz. I've tried the Intel XMP Profile1 and when I save it reboots once or twice and goes back to defaults. Currently memory is at 1600mhz with timing of 7-7-7-20-1T at 1.92V and Processor is set to 1.28V

    So the memory is showing up running at 1600mhz and you want to get it to 1866mhz? Is that your problem?

    I guess you can say that. Actually the motherboard on auto puts this memory at 1333mhz. I am able to get it up to 1600mhz. I would like to run either 1800mhz or 1866mhz.

    Next time Please fill the table in again with ONLY your exact settings, the way you put things I am not sure what you are using exactly

    It is just confusing, not trying to be picky or anything


    Try this for 3.4 for now. What cooler do you have? >>>>

    CPU Voltage Control_______ [1.25] << More, all up to your CPU but this is not enough. Set for sure high enough to boot then you can lower later. Actual voltage will be lower then you set here as well, so keep that in mind. Do not use Auto. Maybe 1.38-1.44 actual shown in CPU-z. Check what your Vdrop/vdroop is now and adjust accordingly. You can do this by loading a profile you can boot, like stock, and setting a voltage manually and then look in windows and see what you get in CPU-z at Idle and Load Vs. what you set in the BIOS. This difference will vary at different voltage settings, but should remain about the same

    Thanks for your help so far.
    This is my cooler CPU-340 (CPU), [no nozzles] - Water cooling systems, pc liquid cooling kit, cpu, video card, hard drive. It is the cpu-340 waterblock from Koolance.

    All I did on the table is place my actual settings on the lines you provided. But I will redo table now to show current setup.

    Ahh ok, just wondered if you was using stock cooler or not. Nice to see you are not.

    Ya, that table is much easier to read, thanks. So try out the settings I gave ya, as Auto is not going to be stable most often. Try to see all things I put a value for, using the highest at first for the ram timings

    You are using 777-20 and Performance enhance Turbo, that is likely your main issue aside from some voltages that is holding you back. 777-20 is usually only good till about 1333, and performance enhance turbo is only going to cause you issues for sure since you are already unstable.

    Please try working with the above and see what you can get running

    Well this is pretty weird. Pc is up and running with the setting you gave me and on the setting that you gave me like 4-6 and 8-12 I used the lowest number. Pc booted up fine and bios shows it's running 1700mhz but Cpuz1.49 shows Memory at 800mhz and cpu at 3.2ghz with cpu voltage at 1.35 temp prob shows cpu at 41C.
