I'm having two adata rams 2400 mhz .. one is normal one and other is with a heat sync ... When I open CPU z it only show my Nb frequency as 1199.33 . .. isn't it supposed to be 2400 !??
Question Is my Nb frequency correct ?

DDR stands for Double Data Rate, so multiply what you see by 2, and that's your 2400.
DDR can transfer on the rise and fall of the clock cycle, so it's effective speed (as advertised) is twice the actual speed (as listed in CPUz).
It's marketing. The actual MHz speed of RAM is what CPUz reports. But it's data rate (megatransfers per second ) is double, and that's what marketed to us as speed in MHz, while technically it's not.
