American Megatrends MAN-758 manual Install Memory, ∙ 32MBx32or36SIMMs

Step 7 Install Memory

System Memory There are eight 32-bit SIMM (Single Inline Memory Module) sockets. System memory must be populated one bank at a time. Each bank has two sockets.

Each bank must be populated with the same type of SIMM. If a 4 MB SIMM is installed in the first socket in Bank0, then the same type of 4 MB SIMM must be installed in the second Bank0 SIMM socket. The minimum amount of system memory supported by the MegaRUM PCI is 8 MB. Each socket can hold one SIMM. You can use:

∙1MBx32(or36),

∙2MBx32(or36),

∙4MBx32(or36),

∙8MBx32(or36),

∙16MBx32(or36),or

∙32MBx32(or36)SIMMs.

The MegaRUM motherboard will support 128 MB SIMMs when they become available, permitting up to 1 GB of system memory to be installed on the motherboard.

Fast Page Mode, EDO, and Burst EDO SIMMs cannot be mixed. The motherboard supports SIMMs operating at 60 or 70 ns (RAS access time). Set the Chipset Setup DRAM Speed (ns) option correctly.

Memory Display System memory is reported by AMIBIOS as it boots and again when the AMIBIOS System Configuration Screen is displayed just before the operating system boots. The memory displayed by AMIBIOS on the System Configuration Screen is 384 KB less than the total memory installed.
