Ram Question

Quick Question.

DDR3 1600 = 800 or 533 mhz in Bios with a 1:2 divider.

Does the ''3'' in DDr3 make the speed 3x or is it based of the divider?

The 3 in DDR3 means the third generation of DDR memory.

You still double the speed because DDR stands for Double Data Rate.

So DDR3-1600 has an actual frequency of 800MHz, but because it's DDR memory, it transfers data two times every clock cycle, so you double the frequency to get it's 'effective' speed.

Thanks for the help. :toast:

It is two times so 800x2=1600

DDR3 are still double data... unlike DDR5 which is x4 but that is for graphics only so far anyways...
