Older computers usually will not work with newer higher density module sticks of RAM. What it's referring to...is the amount of RAM that each module on your stick of RAM has.

Example....an older type of RAM stick that's 256 megs total, would be made up of 16 chips made up of 16 megs each. 16x16=256. You'd have 8 modules on each side of your memory stick.

Newer types of RAM would perhaps have 8x modules of 32 megs each mounted on 1x side of the stick, or perhaps 4x on each side of the stick. Or even 4x modules total...of 64 megs each...mounted on one side.

Older computer BIOS usually cannot work with individual memory modules being above a certain size in megs.

These older types of memory aren't being made as much on the product line anymore, and/or of are limited stock, or are made in limited production batches...hence the higher price.
