Frecuency RAM Issue

[leo.tc_07]

Hey guys i want your help,i have 16gb 2x8 2400 (CMD16GX4M2B2400C10) set ; the problem is that two months ago the resume of speecy show 16gb 2400 memory speed and now show me 1200 ram speed.

I did O.C two times without problems.

My setup is

Psu:GX Cooler master 750
Processor: Intel core i5 6600 k
Mobo: Asus Maximus 9 apex
Gpu: Gtx 1060 windforce.

What does windows say in performance tab? Many software advertise the true frequency while others use the double (ddr-double data rate). If you are looking at the correct tab withing speccy, then maybe an update makes the program report the true frequency which is 1200 mhz (x2= 2400)

i think your confused or reading the wrong info.

The 2400 is the speed of the ram. The 1200 is the Dram frequency, operated on a 2;1 ratio, which equates to 2400mhz, approx. The Dram frequency is determined from the bus speed, which in most cases is 100mhz x 12 or whatever the ratio is. The bus speed fluctuates a little ranging anywhere from 99mhz to 100mhz in small increments.

If you use something like CPUID, you can look at the ram speed, which will say 24oo, and the 'SPD' tab which will show the ram running at 1200 with a 2;1 ratio. DDR means double data rate, so 1200 x 2 = 2400.
