Tip: “X8” means that
each chip on the
module bank is 8 bits,
and “X16” means each
chip is 16 bits. We
know that each
memory bank is 64
bits. Therefore, if a
memory module has 8
chips on each bank it
is “X8”, and if there are
4 chips on each bank,
it is “X16”.
Note: Due to the limitation of memory controller in the Athlon 64
CPU, we do not recommend you to install three DDR333/266
modules.
