RAM frequency should be 800?

Specs: Windows server 2003 enterprise, -
I've always left my BIOS to do all the setup work on my hardware automatically (its a phonex award bios). I was breezing through some of the advanced settings just now though and there was an option for DDR2 frequency. Its set to auto like a lot of other settings.

Out of pure curiosity I downloaded CPU-Z and looked at what it said the DRAM frequency was running at. It says 200.9mhz give or take a bit of fluctuation.

Question is, my Ram is DDR2 800mhz... Does that mean then I should change the bios from auto and set it to 800 or, what?

Oh... Hang on a minute. I think I just figured it out. I've got four sticks of 1gb DDr2 ram modules they're rated at 800Mhz but, it says in CPU-Z they're at 200mhz.

Though 4x 200 is 800 so I suppose for whatever reason there's nothing that needs changing. Unless this observation of mine is a coincidence, but somehow I doubt it.

DDR2, Double Data Rate x2 = 4. Your settings are where they should be.

Look at the link bleow.

DDR2-800 is supposed to run at 400MHz, not 200MHz. It has nothing to do with the number of memory sticks. Are you sure the frequency you're looking at is for the RAM & not the CPU?

Yea. This is under the DRAM advanced settings in the BIOS. Even if I manually set the timings and set the frequency to 800 CPU-Z still shows it as running at about 200.9MHz
