What is "module configuration" regarding RAM?

[dandee2005]

Could someone please explain to me whether I need to know about "module configuration" when I decide on what RAM I need to purchase?

What does this term "module configuration" [eg 64x64, 16x64, 32x64, 64x64, 128x64] mean when speaking about RAM and does it relate to the capacity of the RAM eg. 16X64 is for 128mb, 32x64 is for 256mb and so on..?? I need to purchase 1 X 256MB DIMM SDRAM Non-parity, PC133 3.3v so should I also look for the MC spec as well?

I always thought the module configuration just relate to the path by which the memory is stored and didn't relate whatsoever to the size of the ram so you can have 256mb that is 32x64 and/or 16x64...

Sorry for the boring topic but RAM can never be interersting lol. Thanks to anyone who posts some help..

eg. 32x64:
The first number is the amount of chips in all the modules youre buying (a kit for example) and the second one is the amount of memory each chip can handle. So 32x64 would have to be a 2GB kit/module.
The last configuration looks unsual (128x64), where are you seen it?

so should I also look for the MC spec as well?

Not really as it doesnt affect performance or compatibly.

Thanks a lot dario, really appreciate your post! I'm glad I don't need to look at the specs of RAM in terms of the MC, there is enough already to look at> ecc/parity, buffered, capacity, pin number, mhz etc.. argh too much lol!
