Server memory kit for HP ProLiant G6 G7

This 64GB kit contains four 16GB DDR3 1333 registered ECC modules built for HP ProLiant DL160 G6 DL165 G7 DL170e G6 DL170h G6 and DL180 G6 servers. It is designed for workloads that require error correction and registered buffering in a 240-pin form factor. The modules operate at 1.5V with CL9 latency. Desktop systems cannot use this memory.

Registered ECC DDR3 1333 2Rx4 compatibility

The decisive specification is the registered ECC DDR3 1333 2Rx4 organisation on a 240-pin DIMM. Only platforms that explicitly support registered ECC DDR3 at this speed and rank configuration will accept the kit. Mixing with unbuffered modules is not supported. Verify the server model against the listed ProLiant series before purchase.

Thermals noise and power in normal use

The modules run at the standard 1.5V JEDEC voltage without heat spreaders so they rely on chassis airflow for cooling. Power draw per module is low at DDR3 1333 speeds and registered operation adds negligible overhead. Acoustic impact is zero because the kit has no active cooling components.

Questions about this item

What does the 1333 speed mean once the kit is installed in a ProLiant server?

The modules run at DDR3 1333 (PC3 10600) with CL9 latency, delivering the rated throughput when the server memory controller is set to 1333 MT/s.

How does the registered ECC interface affect what the memory can do in practice?

Registered ECC adds a register between the DRAM and the memory controller, enabling the 16 GB density per module while providing error correction for server workloads.

What physical slot and voltage does each 16 GB module need to fit the listed ProLiant models?

Each module is a 240-pin DDR3 DIMM operating at 1.5 V, matching the DIMM sockets on the DL160 G6, DL165 G7, DL170e G6, DL170h G6 and DL180 G6.
