DDR3 Memory

Hello, I've bought a Motherboard bundle from Maplin last week and was supposed to have 1333mhz DDR3 Memory.

I'm sure there's some logical explanation for this as you're about to tell me.. :P

but why does CPU-Z show my DRAM Frequency as 666.7MHz?? Thanks in advance.

(also sorry if I posted in the incorrect section, none of the options seemed suitable)

  1. DDR (double data rate) transmits signals twice per clock cycle, so it actually runs at 666.7MHz but behaves like 1333.3 MHz.
