Removal and Replacement Procedures 2-37 SDRAM Memory Compaq ProLiant 8000 servers use industry-standard synchronous dual inline memory modules (DIMMs) with single-bit error correction and single/multiple-bit error detection down to a single DIMM. Memory is expandable to 16 GB (16 x 1-GB DIMMs) by using all 16 DIMM sockets, two DIMM sockets to a bank. Both DIMMs in a bank must be installed at the same time. Both DIMMs in a given bank must be the same size, type, and speed. Compaq ProLiant 8000 servers support 128-MB, 256-MB, and 512-MB 100-MHz SDRAM DIMMs (ProLiant 8000 will support 1-GB DIMMs when available). IMPORTANT: The Power-On Self-Test (POST) warns of non-supported DIMMs. Mixing of memory speeds on a memory expansion board is allowed, but the memory expansion board will run at the slowest memory speed installed. Dual Inline Memory Modules Table 2-3 gives examples of DIMM upgrade combinations for Compaq ProLiant 8000 servers.

SDRAM Memory
Compaq ProLiant 8000 servers use industry-standard synchronous dual inline memory modules
(DIMMs) with single-bit error correction and single/multiple-bit error detection down to a
single DIMM. Memory is expandable to 16 GB (16 x 1-GB DIMMs) by using all 16 DIMM
sockets, two DIMM sockets to a bank. Both DIMMs in a bank must be installed at the same
time. Both DIMMs in a given bank must be the same size, type, and speed.
Compaq ProLiant 8000 servers support 128-MB, 256-MB, and 512-MB 100-MHz SDRAM
DIMMs (ProLiant 8000 will support 1-GB DIMMs when available).
IMPORTANT:
The Power-On Self-Test (POST) warns of non-supported DIMMs. Mixing of memory speeds
on a memory expansion board is allowed, but the memory expansion board will run at the slowest
memory speed installed.
