1866MHz RAM runs only at 1333MHz even after enabling XMP

Hi.

I have 4 8G CORSAIR VENGEANCE memory
2 x CMZ16GX3M2A1866C10R
2 x CMZ16GX3M2A1866C10

on Sabertooth X97 Mk2

Even after enabling XMP on Bios, it still runs only at 1333MHz

CPU-Z SPD is shown like below

    You may well be at 1866 - need to look in the Memory tab, check frequency - it will tell true freq - here should be about 933 - then you take that x 2 = effective (1866) as this is DDR (DOUBLE data rate). The SPD tab simple shows the info programmed into the SPD of the sticks of DRAM ;)

    Thank you.. Memory tab indeed shows 933 MHz. Not sure why from Bios till Windows Task Manager shows it as 1333.
  3. Windows task manager only reads the rams label, if you have done everything correct it is actually running at the speed you set it too. A way to check would be to test it on default then with it turned up to see if it is actually working.
  4. Many programs simply look to see what the mobo default is for DRAM and show it regardless of what you are running at

    Hello guys can you help me
    ;)

    1.Can i know the difference between hyper x savage and fury and does it support and runs on my pc which is mobo GF615M-P33 MS 7597 and amd phenom ii x2 555 if im planning to buy the 8gb 1800 mhz or the 1600 mhz either savage or fury DDR3 depends on the compatibility

    2. If im planning to upgrade my motherboard, which one i should buy in order for me to use it directly on my old pc setup? the 1800 or 1600mhz hyperx Fury or Savage that i can use for now as my current ram is not working
