That should explain.

O.G.C

DDR means Double Data Rate. This means whatever the base or raw frequency of the memory is, it's effectively doubled. This applies for DDR, DDR2, DDR3 and their graphics card derivatives.

So for example:
DDR2-800 has a raw frequency of 400MHz. This is what CPU-Z picks up.

Just to add a bit more confusion, GDDR5 effectively quadruples the raw frequency :P
