168-pin DIMM modules specifications
¡j
According to the standards defined by JEDEC, there are a lot of
different types of specifications for 168-pin DIMM sockets. Here
are the possible types:
3.3V UNBUFFERED DIMM
3.3V BUFFERED DIMM
5V UNBUFFERED DIMM
5V BUFFERED DIMM
These types of DIMM modules differ not only by the electrical
design, but also by their architecture. So, if you buy different types
of DIMM modules, you will not be able to insert them in the
DIMM sockets. Currently, the standard for PC is 3.3V
UNBUFFERED DIMM, which is the standard supported by this
series.
After installing the DRAM, the BIOS of the mainboard will automatically
detect the size of the memory installed on the mainboard. The description of install
168-pin DIMM modules as follows :
-
The maximum memory size is 256M bytes.
-
Support possible for single density or double density
memory modules.
-
Memory modules supported:
1Mx6

48M

, 2Mx64
¡i
16M
¡j
,
4Mx64
¡i
32M
¡j
, 8Mx64

or 16Mx64

.
DIMM1 is the first pair, DIMM2 is the second pair.
Usually, you first insert modules in DIMM1 socket, than
in DIMM2 socket, but it is possible to do the reverse.
You can also directly refer to table 2-1.
