I have 6gb triple channel kingston 1600 mhz, and in cpu-z is showing in SPD section on slot 1 3 5 - 800, 800, 667 - is there any way i can do something to make it work at 1600, or where can i see this speed?
BTW, in bios i just changed from auto to 1600mhz speed, but cpu-z shows a slight improvment at memory tab "nb frequency" from around 2500 to 3200 or smth, and at timing with dram frequency from 500 to 800
Motherboard : Asus P6X58D-E
 
Solution
You have 1 stick that is probably older than the other 2 if all are 1600 sticks, what is showing in the SPD is the default boot freq, with the older being 1333 and the newer sticks being a 1600 default...Look in the Meemory tab to see what they are currently running at, it should show 800 in the freq window since this is DDR (DOUBLE data rate) so true freq (800) x 2 = effective rate (1600).....if it shows about 666-667, then they are at the mobo default, to correct this, go into BIOS enable 1600 and select profile 1

They are all labled 1600 mhz, they are all kingston, just 1 is a little newer, had 4 now i have 6, but i checked for it to be the same speed. Also this is the first time i ever knew about things happening like this. I never checked my ram speed till now, when i find out that it never worked at 1600, even if they are:).

I'm sorry to say but one is not 1600, download the newest cpu-z and check again, oh Kingston is 1.65V, Intel chipset X58 doesn't like it nor does Intel chipset X79, buy 1.5V ram
