Memory Population Rules - MSI MS-6319 Manual

2.3-3 Memory Population Rules

1. Support only SDRAM DIMM w/o ECC function.
2. To operate properly, at least one DIMM module must be installed.
3. DIMM Slot configuration:
4. The DRAM addressing and the size supported by the mainboard is
shown below:

64MB 4Mx16
128MB 16Mx8
128MB 32Mx4 (reg)
5. When Populating the DIMM slot with mixed DRAM density & width.
You should populate the largest DRAM Density & width into DIMM 1
first, then DIMM 2. The smallest should always be populated to DIMM
3.
For example: If you had a DIMMs with 16Mx8 and 4Mx16 Density &
Width. You should populate DIMM1 with 16Mx8, and populate DIMM2
with 4Mx16. Note: This is not recommended, for this may cause system
malfunction.
Note: It is highly recommended to use DIMMs with the same Density &
Width.
