Memory frequencies halfed since mobo change

I noticed yesterday in CPU-Z that my RAM frequencies are running at half speed, and I think it's because I changed my motherboard/CPU a few weeks ago.
Is there anyway to make them run at proper speeds again? I've never really played around with RAM, so don't know much about it..

I'm using a Gigabyte Z68 and a 2500K. The RAM modules are 4x2gb Kingston, 2 of them 1066 and the other set 1333.

Any help is greatly appreciated!

Doesn't RAM run at the lower frequency if there are different sets of frequencies?

eg It'll run at 1066 instead of 1333

For DDR(2,3) the data rate is double the frequency - hence Double Data Rate. Your frequency should actually be half the RAM speed, either 533 or 667.
That being said, I don't use CPU-Z, so I don't know which value it is supposed to show.

Check your BIOS settings and look for your RAM frequency. If you are seeing 333, then you do have a problem.

I noticed this with my RAM as well. The BIOS will display the number you are expecting, but CPU-Z will show the frequency. I believe it is as LurchFrinky has said.

I see, so there's no problem? CPU-Z displays exactly half of the actual RAM speed, so I guess not. I just hadn't noticed it before I upgraded the motherboard, so figured something was up. Thanks for the feedback!
