Memory Options; General Memory Configuration Requirements - HP 155606-001 - ProLiant - ML570R01 User Manual

Memory options

This server supports up to four memory boards. Each memory board contains six DIMM slots for a total of
24 DIMM slots in the server. Memory can be expanded by installing PC2-3200R Registered DDR2 DRAM
DIMMs.
The server supports a host of AMP options to optimize server availability:
•
Advanced ECC (hot-add enabled)
•
Advanced ECC (hot-add disabled)
•
Online Spare Memory (on page 62)
•
Hot-Plug Mirrored Memory (dual- and quad-board)
•
Hot-Plug RAID Memory (on page 64)
Hot-plug operations can be hot-add or hot-replace. Hot-add makes additional memory resources available
to the OS. Hot-replace allows failed or degraded DIMMs to be replaced while the server is running.
The maximum supported memory per memory board is 16 GB using four 4-GB dual-rank DIMMs.
Although six DIMM slots exist per board, the system architecture allows a maximum of only four dual-rank
DIMMs per memory board to optimize performance.
For an overview of single- and dual-rank DIMMs, refer to "Single- and Dual-Rank DIMMs (on page 61)."
For DIMM slot locations and bank assignments, refer to "DIMM Slots
23)."

General memory configuration requirements

The following configuration requirements apply regardless of the AMP mode.
•
DIMMs must be installed in pairs.
•
DIMM pairs in a memory bank must contain DIMMs with the same part number.
•
Always populate the memory boards in sequential order: Board 1, Board 2, Board 3, and Board 4.
Any deviation from this requirement results in the server booting in Advanced ECC mode and
Advanced ECC guidelines apply.
•
Always populate the DIMMs in sequential order per bank: Bank A, Bank B, and Bank C.
•
Dual-rank DIMMs
rank DIMMs (see table).
•
If dual-rank DIMMs are installed in Bank A and Bank B, no additional DIMMs may be installed in
Bank C.
•
The following table lists all seven valid combinations of single- and dual-rank DIMM configurations
for a memory board. "Single" indicates a bank of single-rank DIMMs. "Dual" indicates a bank of
dual-rank DIMMs.
NOTE: A bank contains two DIMMs.
