So I have 8gb of 2666mhz ram. However, when I look in task manager I see it says speed 1333mhz. How do I change the speed. I guess I have to go into 

BIOS, but I honestly have no idea what to do....

 

 

Cheers

Task manager is showing Mhz not Mt/s Ram speed like 2666 is not actually Mhz its Mt/s (Mega transfers/sec) Due to DDR being Double Data Rate, It can be accessed at the top and bottom of the clock cycle.

It's running correctly.

DDR = dual data rate

Whatever you see in a program for speed (so the 1333Mhz) * 2 = RAM speed as shown by the RAM manufacturer.

 

You probably have XMP/XAMP/DOCP turned on in the motherboard BIOS.

1333 x 2 is 2666mhz. Double Data Rate
