Question Is my ram okey?

My RAM is a 3200 kit so it shows 1/2 of that (~1600) in CPUz:

So if you have 1866 RAM it will show as 1/2 of that (931/932) in CPUz as well.
But if it used to show as 1866 in CPUz (for a 3733 kit) then there is a problem.

What exact model number RAM, MB and CPU do you have ?
It used to show 1866 on task manager, I read about double data rate but I thought it was only on dual channel, what is weird is that on my pc I doesnt show the ram at half like it does on my laptop
