The older 4th generation chipsets use coarser DRAM multipliers

Since your FSB is set to 1333 MT/s, the FSB clock is 333Mhz.

The DRAM clock that you have right now is 400Mhz, which is the correct clock for DDR3-800. This is generated by multiplying the FSB clock by 5/4.

If you want DDR3-1333 you need to boost this to 667Mhz. You can get this by changing the multiplier from 5:4 to 2:1
