Need help picking out RAM for C2D

Im getting the 2.13GHz 800MHz FSB C2D processor...what memory would be best for this processor...I will be running dual channel...would like to have the CPU and RAM match 1:1 if possible...was looking at a website and it showed this...

DDR2 800 (400Mhz) = 6400MB/Sec 800MHz FSB * 8 = 6400MB/Sec...would this be the best memory to use for this processor...it looks like a 1:1 match to me...let me know if this is correct...trying to figure out everything....please explain in detail if you can...thanks
 
Umm what Core 2 Duo CPU are you getting, I thought they have a FSB of 1024Mhz. Correct me if I'm wrong people. I have a X6800 and it has a FSb of 1024Mhz. I would definitely opt for the DDR2 800 or the fastest RAM you can afford.
Its my understanding that all if not not most Core 2 Duo CPUs have a FSB of 1024Mhz.
 
Hmm, maybe its just me, i have just done some extra research and i have indeed found some Core 2 Duos that has a FSB of 800Mhz. Well I still think that DDR2 800 RAM is the way to go, why not get the fastest component out there? What have you got to lose except your hard-earned? :P

You would need to know what motherboard you are using with this cpu. The motherboard manual will tell you what compatible memory to use. Some only can go up to 667mhz. What motherboard are you using?
 
The E4xxx series have an 800Mhz bus speed. Keep in mind that if you overclock the CPU, you'll be increasing the bus speed and hence you probably won't be able to run 1:1 anyway.

As johnb35 said, you'll also need to make sure your motherboard supports it. You can still use DDR2-800 if it doesn't, but not at the full speed (it'd only be useful if you were overclocking in that case).

Also keep in mind that while there are performance benefits to be gained with DDR2-800, it shouldn't be done at the expense of other components. Depending on your other specs, you may find that an improved CPU or GPU would give you more performance for the money.
