Advanced ECC (Standard) Memory Technology
This section details the features and DIMM installation requirements for advanced
ECC memory.
Features
Advanced ECC memory has the following advantages:
•
•
•
•
•
•
The server supports up to 32 GB of system memory. Each memory board
supports up to 16 GB of system memory using 2-GB DIMMs.
Advanced ECC memory detects both single-bit and multi-bit errors, and corrects
single-bit errors. It can also detect and correct 4-bit errors that occur within a
single DRAM chip on a DIMM.
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 on all installed memory boards.
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 on the website:
www.compaq.com/products/servers/technology/memoryprotection.html
IMPORTANT: You must power down the server before installing additional DIMMs, unless
using hot-add or hot-mirror functionality.
IMPORTANT: Follow all DIMM configuration requirements carefully. If the DIMMs are not
configured properly, you receive an error message during POST.
