Rdimm Maximum Memory Configurations; Udimm Maximum Memory Configurations; Low Voltage Dimms; Advanced Ecc Memory Configuration - HP PROLIANT ML330 G6 User Manual

Advanced Memory Protection options are configured in RBSU. If the requested AMP mode is not
supported by the installed DIMM configuration, the server boots in Advanced ECC mode. For more
information, see "HP ROM-Based Setup Utility (on page 85)."
For the latest memory configuration information, see the QuickSpecs on the HP website
(http://www.hp.com).

UDIMM maximum memory configurations

The server supports a maximum of 24 GB using 4-GB dual-rank UDIMMs.

Low voltage DIMMs

Low Voltage DDR3 DIMMs operate at a lower voltage (1.35V) than standard voltage DDR3 DIMMs
(1.5V), and therefore consume less power. However, LVDIMMs are configured to operated at standard
voltage levels (1.5V) under the following conditions:
•
If LVDIMMs are mixed with standard DDR3 DIMMs on the same server, the LVDIMMs operate at
1.5V.
•
If there are two dual-rank LVDIMMs per channel on any populated memory channel in the system
running at 1333 MHz, the LVDIMMs operate at 1.5V.
This setting preserves maximum memory subsystem performance. To have DIMMs operate at 1.35V,
configure the Maximum Memory Bus Frequency option in the ROM-Based Setup Utility to 1066
MHz.
•
If there is one quad-rank LVDIMM per channel on any populated memory channel in the system
running at 1066 MHz, the LVDIMMs operate at 1.5V.
This setting preserves maximum memory subsystem performance. To have DIMMs operate at 1.35V,
configure the Maximum Memory Bus Frequency option in the ROM-Based Setup Utility to 800 MHz.
LVDIMMs are only supported for use with the Intel® Xeon® 5600 series of processors.

Advanced ECC memory configuration

Advanced ECC memory is the default memory protection mode for this server. Standard ECC can correct
single-bit memory errors and detect multi-bit memory errors. When multi-bit errors are detected using
Standard ECC, the error is signaled to the server and causes the server to halt.
Advanced ECC protects the server against some multi-bit memory errors. Advanced ECC can correct both
single-bit memory errors and 4-bit memory errors if all failed bits are on the same DRAM device on the
DIMM.
