Step 4 Install Memory
System Memory System memory for the Megaplex is mounted on the Series 769 CPU board,
which supports up to 4 GB of system memory, and the Series 777 memory card,
which supports an additional 4 GB of system memory. Use 60/50 ns x 72 EDO
Mode 3.3V 168-pin ECC buffered memory module DIMMs (Dual Inline
Memory Modules).
The DIMMs in Megaplex are different from the x 36 SIMMs used by most other
motherboards. The Megaplex memory modules are a new JEDEC-standard
defined for 8-byte wide common CAS memory supported by most memory
manufacturers. Computers that require a large amount of memory (such as
servers) use DIMMs.
System Memory Requirements You must install DIMMs in all four slots of a bank. The eight
memory banks are Bank0, Bank1, Bank2, and Bank3 on the CPU board, and
Bank4, Bank5, Bank6, and Bank7 on the memory expansion board. Each bank
of memory has four DIMM sockets.
Within a memory bank, all system memory must be of the same type. Mixing
different types of DIMMs is not permitted.
All memory banks must have the same type and size DIMMs. Mixing different
types of DIMMs is not permitted.
Use AMI recommended memory modules only.
Rules for ABP and C2C Memory banks can be populated on either Series 769 or the memory
expansion card. If you distribute memory between the CPU board, and the
memory board, you can use ABP (Address bit permuting) and C2C (Card-to-
card interleave) to improve system performance.
