Q: Why are there SDRAM SODIMM price differences among
memory modules that appear to have the exact same specifications and what are
the differences between 256MB SDRAM SODIMM High Density and 256MB SDRAM SODIMM
Low Density memory chip?
A: 256MB PC100 High
Density memory modules are less expensive and have only chips on one
side of the card (single sided 8 chips memory). However a great many older
systems in use today often cannot support the newer, higher density memory.
Older memory controllers require
256MB PC100 Low Density memory -
a memory module
with twice as many chips because the chips used on that have a twice-lower
density. 64MB and 128MB modules can be single sided however when it comes to
256MB module – the density becomes too high for the motherboard to support a
single sided module.
