Server memory module

The HPE 500660-B21 is a 4 GB DDR3 registered DIMM built for ProLiant G6 servers. It runs at 1066 MHz to the DDR3-1066/PC3-8500 standard and is sold as a single module. System administrators use it to expand memory capacity in compatible rack and blade platforms.

Capacity upgrade path

This module replaces smaller DDR3 DIMMs or fills empty slots in supported G6 systems such as the BL460c, DL160, DL380 and ML150. The jump is worth it when workloads exceed the current memory ceiling and the platform accepts registered DDR3-1066 parts.

Build integration

The registered signal processing requires a server motherboard that supports registered DDR3 memory. It fits standard DDR3 DIMM sockets in the listed ProLiant models and frees up additional slots for further expansion when the platform allows.

Questions about this item

Does the 500660-B21 module fit a ProLiant BL460c G6 server?

Yes, the module is listed as compatible with the ProLiant G6 server series including the BL460c, DL160, DL380 and ML150 models.

How is the registered DDR3 DIMM installed, and what step is often missed?

Align the notch with the slot key, press firmly until the ejector clips lock automatically; the step often missed is verifying both clips are fully engaged to ensure registered signal integrity.

When should the 4GB DDR3-1066 module be replaced in a ProLiant server?

Replace the module if memory diagnostics report correctable errors that increase over time or if the server fails POST with memory beep codes indicating a DIMM fault.
