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.

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.
