for instance at tank guys : http://www.tankguys.biz/ddr2-55515-1200mhz-p-1716.html
2 Gb Kit DDR2 (2x 1Gb) 5-5-5-15 1200Mhz PC2-9600
[TXDD2048M1200HC5DC]

the motherboards that are out say that they support DDR2-667... DDR2-800 etc etc.

you overclock the memory..and get higher bandwidth..and it performs like faster memory.

so if i bought (cannot afford but lets just say ;) ) the memory above. put it in my CFX3200M2/G . it would perform like its specs and then overclock from there and I would still see the bandwidth from it being overclocked? or is there that limit that each board reaches. hell, would that memory even work in my mobo?

It would probably work, but not at its rated speed by definition. Memory is limited by the clockspeed of the FSB.
One way or another it uses a divider to determine the memoryspeed.

PC2-9600 memory runs at a clockspeed of 600MHz (DDR2-1200).
To actually run it at this speed you would for instance need an FSB of 400MHz and a divider of 2:3.
This indicates the ratio between the FSB and memory clockspeed; 400MHz ÷ 2/3 = 600MHz.

There are several reasons why this kind of memory exists. One is for overclocking purposes.
Because the memory already runs at 600MHz by design, it rules out the possibility of the memory being the limiting factor.
Combined with the fact that these modules use highly binned ICs (chips) there's a good chance it will go even higher.

Another reason is simply marketing, competition. Producing the fastest memory is a big deal for memorymanufacturers.
Just like some cars are capable of driving 250MPH, though nobody really does it on a daily basis. Not the best comparison, but you get my point.

Now, buying this memory isn't always the best option because it's relatively expensive.
It's generally better to get information regarding the ICs used on it, trying to find cheaper memory that uses the same. Only you can make that decision.

you told me exactly what i needed to know. thanks. ;)

my car goes to at least 160 thank you very much....


LOL.
