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:
•
1 MB x 32 (or 36),
•
2 MB x 32 (or 36),
•
4 MB x 32 (or 36),
•
8 MB x 32 (or 36),
•
16 MB x 32 (or 36), or
•
32 MB x 32 (or 36) 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.
