CPU and RAM settings correct?

Specs: Windows XP
I ran CPU-Z on my computer and got some confusing info. Im pretty much a noob when it comes to this but I want to learn.
Intel E6420 2.13Ghz and PC-6400 RAM, Rated FSB 1067.6Mhz (Shuttle FV30V10)

Core speed runs at 1.6Ghz(6x multiplier)most the time but changes a few times per min to the rated chip speed of 2.134Ghz(8x multiplier) bus speed remaining fairly constant at 266.8Mhz. Why does this number change? Is it possible to set the BIOS for it not to change? I imagine that it is possible but how exactly?

Second the DRAM freq reads 333.4Mhz. Shouldnt this freq read 400Mhz with PC6400? If so, should, how and would it be beneficial to change it?

I tried googling that Shuttle model number & the only thing that came up was this thread? You apparently typed it incorrectly.

The E6420 is supposed to run at 8 x 266MHz. If the multiplier is lowering to 6x, it's because you have Speedstep (aka EIST) enabled in the BIOS. If you want the CPU to run at full speed at all times, disable it.

And regardless of the fact that you have PC2-6400 which is *supposed* to run at 400MHz, it should be configured to run at 266MHz to match the CPU frequency. Another option would be to increase the CPU frequency to match the RAM...either both at 333MHz or both at 400MHz. That will overclock the CPU though so you'd have to make adjustments to other settings (multiplier, voltage, etc) to keep the system stable. If you had entered the model number correctly, I could have lookeed up the specs & made some recommendations for overclock settings.

Are you sure it's not SD30?
