DIMM Installation Requirements
Observe the following DIMM configuration requirements when installing DIMMs:
•
Use only industry-standard PC1600 registered DDR SDRAM DIMMs in 256-MB,
512-MB, 1-GB, and 2-GB capacities.
•
Install DIMMs in pairs, one bank at a time.
•
Be sure that both DIMMs in a bank are the same capacity.
•
Be sure that bank A is populated.
IMPORTANT: HP recommends that you use only HP DIMMs. Third-party DIMMs may have additional
installation requirements. For information about third-party DIMM installation requirements, refer to the
HP Advanced Memory Protection white paper at www.hp.com.
IMPORTANT: You must power down the server before installing additional DIMMs.
IMPORTANT: Follow all DIMM configuration requirements carefully. If the DIMMs are not configured
properly, you receive an error message during POST.
The server supports three types of optional Advanced Memory Protection:
•
Online spare memory
•
Single-board mirrored memory
•
Hot-plug mirrored memory
Each type includes Advanced ECC protection.
Additional Requirements for Online Spare Memory Technology
In addition to the DIMM configuration requirements for advanced ECC memory, observe the
following DIMM configuration requirements when installing DIMMs for online spare
memory:
•
Bank D is the online spare bank and must be populated when the server is configured for
online spare memory.
•
DIMMs installed in the online spare bank must be of equal or greater capacity than each
of those in the remaining banks.
