Heya guys,

Im seem to be confused at the moment as to why CPU-z is reading my DRAM Frequency as 533.4 MHz when i manualy set it to 1066 in the BIOS.

I'm still somewhat new to overclocking, but shouldn't CPU-z read the sped as 1066?

The rated speed of 533.4Mhz is correct, it's double data rate which means your set at the effective speed of 1066. Or just take 2 x 533 which equals 1066Mhz. Nothing to worry about.

Yup.... actual vs effective clock rate.

So just to clarify, Each RAM stick (I have two) is running at 533 MHz. (1066 divided by 2)

So lets say i had 3 sticks of DDR2, would each stick then run at 355MHz? (1066 divided by 3)

Nope.

DDR = Double Data Rate.

RAM running at 533MHz can do two operates per cycle so that it can effective work at 1066MHz.

You are confusing that with dual/triple channel. A single DIMM is 64-bit wide. If you controller supports it, you can combine channels to make 128-bit or 192-bit wide channels. However, this only helps if you have large memory requests.
