Hi, I just built a new computer with an AMD A10-7850K and an Asus A88X-PRO. I installed 2 x 4GB of Mushkin Enhanced Redline 991996 (996996) memory, which should be able to run at 2133 MHz in this setup. However, after the install, everything (i.e., BIOS, Task Manager, CPU-Z) was saying the memory was running at only 1600 MHz. So I did some tinkering with the BIOS and think I got the memory running at 2133, but I am getting conflicting feedback. Now my BIOS and CPU-Z say that the memory is running at 2133 MHz, but the Windows 8.1 Task Manager still says they are running at 1600 MHz.

Does anyone know a definitive way to determine how fast memory sticks are running?

Hi,

If you set the memory to 2133 in the BIOS and CPU-Z says that they are at 2133 in the O/S then that is what the memory is running at.

I'll take your word for it, but why would the Windows Task Manager still report that they are running at 1600 MHz?

Windows has never been reliable for memory speeds, that is why there are utilities like CPU-Z.
I would guess that Windows is just displaying the basic SPD for memory speed.
