Purchasing RAM

Okay, probably a simple answer but I want to be sure before I buy.

When looking at DIMMs on a Web site, what is meant in the specs by "x32" or "x64"? The specs on my motherboard say four things:
- Supports 168-pin DIMM module sockets.
- Supports DRAM memory 8MB to 384MB on board.
- Supports Symmetrical DRAM.
- Supports 3 banks DIMM, 3.3V Unbuffered Synchronous DRAM.

I understand points 1, 2 & 4 but what is "Symmetrical DRAM"?

Thanks...

Basically you need to find out what the bus speed of your motherboard is.  If the chip is a p2 350 or higher odds are its a 100mhz bus any slower and its a 66mhz bus.  If its an amd k62 series its probably 100 mhz.  

The only thing for you to read from the points listed above is that you need 3,3v SD ram.

I would get a 128 meg dimm for about 150 bucks and I would be happy.  Be sure that the ram matches your bus speed however.

Don't know about symmetrical!
X32 refers to 72 pin memory that is non parity X36 refers to parity

X64 is non parity 168pin
X72 would be parity 168 pin

Geez, pm3, why so hostile?! Since your answer made no explicit mention of the "x" issue nor the term "symmetrical", I was left to wonder if my original question was clear enough. There's no need to get so insulted - I am simply more satisfied with the other response.
