My motherboard is MSI Z87-G43,
I have installed two Corsair Venegence RAM CMZ4GX3M1A1600C9 in slots 2 and 3. The system only shows clock speed of 1333Mhz during boot. why is it so?? should it not be 1600Mhz?
1) you should install the RAM either in the blue color slots or the black one.
2) Go to the BIOS RAM section, set up the XMP mode, then you will see the RAM speed at 1600MHZ.
