Windows 7 CPU-Z shows RAM running at wrong frequency

[rebel12340]

Hello, I've recently upgraded the CPU, motherboard, and RAM for my computer, and today I was looking at CPU-Z and I noticed that the DRAM Frequency is saying 668.9 MHz. The RAM I bought is DDR3 1866, so the frequency should be around 933 MHz or so if I'm not mistaken, so why is it so low?
RAM: G.SKILL Ripjaws Z Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model F3-1866C9D-16GZH - Newegg.com
Motherboard: ASUS M5A97 LE R2.0 ATX AMD Motherboard with UEFI BIOS - Newegg.com

I'm fairly certain your motherboard and CPU, would allow for down-clocking when idle. Is it just your memory that seems to be under-clocked or does your CPU down-clock as well?

I believe that it is just the memory that is under-clocked. Here's a picture of the CPU tab of CPU-Z to make sure.

I managed to fix the problem. Not really sure, but I believe I had to overclock the RAM in the BIOS.
