CHAPTER 2 HARDWARE INSTALLATION
Note: To use the ECC (Error Code Correct) function, a SIMM module with
parity support must be used. At this time you can turn on the ECC function
in the BIOS setup.
Note: Before using DRAM modules, make sure that that the modules used
is the same as in the above chart.
DRAM Memory Installation
2. DRAM modules can be populated in any order
(i.e. SIMM1/2 does not have to be populated
before SIMM3/4 are used.)
3. DRAM module pairs need to be populated with
the same densities...single or double. For
example, SIMM1/2 sockets must be populated
with identical densities. However SIMM3/4
sockets can be populated with different densities
than SIMM socket pair 1/2. In addition,
asymetric DRAMs of the same type should be
used in a whole row.
4. BEDO, EDO, FP modes can be mixed in the
memory array. However only one type should be
used per SIMM socket pair. For example:
SIMM sockets 1 & 2 can be populated with EDO
while SIMM sockets 3 & 4 can be populated with
FP mode type DRAM.
5. The DRAM timing which provides the DRAM
speed grade control for the entire memory array
must be programmed to use the timing of the
slowest DRAM that is currently installed.
