According to AMD's page, (it will not let me post a link)

Protect investments with a technically superior PC processor
The AMD Athlon 64 processor is the world’s most technically advanced PC processor and the first Windows-compatible 64-bit PC processor. Advanced technologies in the AMD Athlon 64 processor include:

* AMD64 technology which doubles the number of processor registers and dramatically increases the system memory addressability
* Enhanced multimedia instructions support including 3DNow! Professional technology and SSE2/3
* With up to a 2000 MHz system bus using HyperTransport technology with up to 14.4 GB/sec total processor-to-system bandwidth
* An integrated memory controller with peak memory bandwidth of up to 6.4 GB/sec, supporting PC3200, PC2700, PC2100, or PC1600 DDR SDRAM
* Native execution of 32-bit software, allowing today’s PC software to provide leading-edge performance while enabling a seamless migration to 64-bit software

The combination of these innovations and features provides customers with performance they need along with tremendous flexibility. Customers can experience outstanding performance running today’s applications and prepare for the next generation of software without having to upgrade or change hardware. For business customers, this extends system life cycles, simplifies technology transition and reduces total cost of ownership.

Check your motherboard's manual to see if there are any specific brands they recommend (or tell you to stay away from). If there are not, you should generally be okay. PC2100 is PC2100 whether you used it on an Athlon or a P4 - RAM is independent of the processor choice.

In the motherboard manual it says

This motherboard supports unbuffered DDR SDRAM only.

Is that what pc2100 is?

Yes - most RAM you would use with a P4 is unbuffered. PC2100 by definition is DDR SDRAM. Buffered RAM is usually used in servers, so you are probably good to go.

ok, cool... i have been so out of date on hardware stuff, i feel like an idiot. one other question i had is, how much better is SATA devices? what are the benifits? and if im going ot buy some more RAM, should i get the same kind as i have now, or does it matter? if it doesnt matter what kind, is one kind better than the other, like the different MHz?

basically im trying to see exaclty what i need for my new amd64 3800... any suggestions would be helpful... im thinking CORSAIR ValueSelect 1GB (2 x 512MB) 184-Pin DDR SDRAM DDR 400
