Nvidia and Inno3d says 5.4ghz

Also my ran is 1333Mhz but shows 665Mhz wtf my motherboard cant utilize?

Both your VRAM and RAM are running fine.

As renz496 mentions above, the 5.4 GHz is the effective speed that it runs at; monitoring software will report either half this figure (2.7 GHz. MSI Afterburner and Precision X report it like this) or a quarter of it (GPU-Z lists video memory speed as a quarter of the effective speed). This is due to the way GDDR5 memory works (I'm never very good at explaining the specific reasoning behind this, so hopefully someone else will - it's essentially down to it transmitting 4 bits per clock cycle I believe).

As for you RAM, well it's DDR3 which stands for double data rate. Because of this double data rate it effectively runs at double the speed the monitoring programs report it as. So in this...

So in this case, your memory is running at 665 x 2 = 1330 MHz. So your memory is certainly running at the correct speed (your CPU-Z link even says that it's running at 1330 MHz)
