is my memory running in dual channel? and...

is it runnint at 1333mhz?

I'm so confused when it comes to memory, it's about the only component I can't fully understand or overclock.

Here's the info I gather on CPU-Z and my motherboard's app:


the speed being reported seems so low 668??? am I missing something?

My motherboard: asus p8p67-m pro
proc: i5 2500k
ram: 4gb x 2 kingston hyperx blue ddr3 1333mhz
os: win 7 64bit
vid card: radeon 6950 1gb

ddr = double data rate. I.E. 668/667 = 1333mhz. So yes it's perfectly fine. And if it says Dual, then it is! It all looks perfectly normal to me =).

Double data rate (DDR) means it transmits data on the rising *and* falling edges of the signal (or something like that). Although it runs at ca. 667 MHz it transmits twice per cycle, making it effectively ca. 1333 MHz.
