hwinfo shows half RAM speed

I recently enabled the XMP profile for my 16gb Ripjaws V (Dual Channel) but HWiNFO only shows half of the speed it should have.
(It should be 3200mhz but it shows up as 1599.5)

Does anyone know why that is?

It's correct what HWiNFO shows. DDR means Double Data Rate, i.e. it transfers data twice per clock cycle. That's why specifying 3200 MHz as clock rate for DDR RAM is incorrect, while in reality it is clocked at 1600 MHz and does 3200 MT/s (Megatransfers per second). Some vendors do that because it's easier to say, and the majority of people don't know what MT/s are, but they do know MHz.
