[SOLVED] overclocking ram to 3000mhz but windows says its on 1500mhz

[ayoubiee]

So I have 2 ram sticks both 8gb, so 16gb in total. One is on 2133 mhz base clock and the other one is 3000mhz. I know that if you put 2 unmatched ram sticks that they both will run on the lowest speed, which will make them both run on 2133 mhz right?
But that doesnt happen. When I dont overclock them they both will run on 1066MHz and with an xmp overclock they will reach max 1500mhz. Does someone know what the hell is going on?

The one 8gb stick that runs on 3000MHz base is the D4 8gb 3000-16 vengeance LPX. The other stick that runs on 2133 is from crucial but I dont know the name of the stick.

If you are looking in the bios - the frequency the memory runs at on the motherboard is half the rated speed - so 3000 mhz ram has a 1500mhz base frequency, the 2133 runs at 1066 mhz and so on. DDR memory stands for 'Double Data Rate' - it transfers data twice per clock hence the rated speed is double the clock (similar to how a CPU runs at a higher frequency than the bus speed via a multiplier). I think from the sounds of it your memory is working correctly.

You could try using the free HW Info tool in windows to double check what it is actually running at.
