Which RAM is right?

I have decided to get an AS Rock Socket A SiS 746FX ATX A L
motherboard and an AMD Athlon XP 1700+ 1.47Ghz CPU, but how do I know
which RAM to get? I know the motherboard needs DDR SDRAM, and I know
that getting RAM that is too slow will slow down the system and
getting RAM that is "faster" than the rest of the system will have no
effect (I don't plan on overclocking) but how do I know what is the
right speed? And what's this "parity" and "CL2 / CL2.5" business?
Somebody please help!

Use PC133 SDRAM in your system, it's the fastest available non-ECC SDRAM.
Parity memory adds an extra bit for every eight bits of data. It is used
for error detection and correction. ECC ram is parity ram.

And, just how will this person be able to use SDRAM on a DDR motherboard?
DDR has 184 pins.

The Asrock K7S8X supports 184 pin PC3200(200MHz) DDR RAM. You want
Unregistered and non-parity PC3200. CL or CAS refers to CAS latency, which
is a measure of the delay time, in clock cycles, before data is sent. Memory
rated for CAS2.5 has at slight performance advantage over CAS3 RAM at the
same speed. Since you won't be overclocking, either will do fine.Crucial
brand PC3200 is probably a good bet.

Another thing to consider is the crucial memory selector at Dabs

http://www.dabs.com/crucial/crucial.asp

This identifies which memory is suitable for your mobo - you dont have to
buy it from there once identified of course.
