motherboard type

You have and ECS MB. Now you need to do your homework and go to thier website and look fot the info on the memory slots and what type and size chips it supports, and whether or not you can mix different size chips or such. Tocool4u has already given you a good tool to use to find some info( Sisoft Sandra) and Google tells you the maker. You just can't go buy a gob of memory and slam it into a slot. Wrongly configured memoey may cause your system to fail to boot at worse, or it may just slow down etc,etc. Check the MB manual to see exactly what chips have to go in which slots. There are a ton of MB that will not support chips larger than 512meg in a single slot, so check the manual b4 you spend your money.
