HP 2GB DDR3 1600 ECC memory module

This 2GB DDR3 1600 ECC unbuffered DIMM is built for HP ProLiant Gen8 servers. It runs at PC3 12800 speed with CL11 latency and 1.50V operation. The module adds capacity to supported blades, rackmounts and towers used in virtualisation, cloud or database workloads.

Check your server model and slot layout

Verify the system appears in the compatible list such as ProLiant BL420c Gen8, DL360p Gen8, ML350e Gen8 or SL250s Gen8. Confirm the board accepts 240-pin DDR3 unbuffered ECC DIMMs and that the memory population rules for your specific chassis allow this capacity per channel.

Fits Gen8 ProLiant platforms directly

The stick installs in standard DDR3 DIMM slots on the listed servers without adapters. ECC protection helps maintain data integrity for critical applications. Unbuffered design keeps latency low for the supported configurations while freeing registered slots for higher-density modules if the platform allows mixing.

Questions about this item

What comes with the HP 669320-B21 module and is anything else required?

The package contains the 2GB DDR3 1600 ECC Unbuffered DIMM; no extra parts are needed if a compatible ProLiant Gen8 server has a free 240-pin slot.

How do I decide between this 2GB kit and other capacities for my ProLiant Gen8?

Choose this 2GB module when you need a single low-density stick to fill a specific slot or to match existing 1Rx8 population rules on supported Gen8 models.

What does the DDR3 1600 PC3-12800 rating mean once installed in a ProLiant Gen8?

The module will run at 1600 MT/s with CL11 latency at 1.50V, delivering ECC-protected throughput tuned by HP SmartMemory qualification for the listed Gen8 servers.
