Ok, maybe I not explain to u in the correct way.THIS
is the BIOS of your mobo right?
Can you see the part that say "Memory Timming and Voltage"
, you need change the part that say DRAM frequency
to the correct configuration for the speed of your RAM. I'm not sure what is the value, but you could find somsething like 1:1, just select the correct for 667.
Why 667?, because your RAM is DDR3 dual channel and DDR3 means double-data-rate three
, in other words, you need multiply by two the speed that you see in the BIOS, so, 667MHzx2=1333MHZ aprox.
P.D. U can see the speed in the right panel of the BIOS to know what speed are you selecting.
P.D2. If this isn't your BIOS, your real BIOS should be very similar, just look for the same options and do the same steps.
