Hello, I appologize for my addition to the sea of newbie questions,

FSB speed,

I bought this memory: kingston 2x1GB 800 DDR2 PC2-6400

and this motherboard:

The Memory Standard for the motherboard is DDR2 800 and the FSB rate is 1066/800MHz at least according to the motherboard specifications.

so shouldn't both the memory and fsb be at 400mhz for optimal performance?

my cpu-z readout shows fsb frequency at around 200mhz while my memory is at 400mhz, is this some JEDEC standard? if I get my FSB:D RAM ratio to 1:1 it brings down the memory frequency. is my motherboard capable of 400mhz fsb?

If you want to OC your CPU then yes, you can get excellent performance from a 1:1 OC with both the memory and CPU running at 400mhz. However, if you don't want to OC the CPU and leave it at 266mhz, there is a small advantage to having the memory running faster than the CPU. In some cases it is 2% or so faster to use a 4:5 or 2:3 ratio but, there is no huge performance gain in most applications until you increase the CPU speed.

Thank you for the help!

So it's just a limit imposed by a slower CPU? The motherboard is capable of it but I'm likely to burn out my CPU when OC'ing? Or would I be just as likely to overheat the fsb on the motherboard?

I know I need arctic and a good heatsink for the cpu and probably something for the fsb as well... I should have gotten a different motherboard as the fsb seems to be quite hot with this model.

Sensible OCing with adequate cooling can shorten the life of your CPU but, it should not be a drastic reduction. I have had a 2.4c CPU running at 3.3 since late 2003. But, in general, cooling is essential to longevity and stability. What CPU do you have?

I have a Intel Core 2 Duo E6400 @ 2.13GHz

I've read articles saying I can push it pretty far. Plus most people say you'll upgrade before an OC'ed CPU burns out.
