OWC 32GB DDR3 ECC RDIMM kit

This 32GB kit contains four 8GB DDR3 1333 PC3-10600 CL9 registered ECC modules built for HP ProLiant DL160 G6, DL165 G7, DL170e G6, DL170h G6 and DL180 G6 servers. Each 240-pin DIMM runs at 1.5V with a 2Rx4 organisation and no heat spreader. The kit replaces HP part numbers 500205071, 500205171, 500206071, 500662B21, 501536001, 593913B21, A0R56A, FX622AA and FX622UT.

Sustained-load behaviour

Registered ECC modules add a clock cycle of buffering and single-bit error correction, so data integrity is maintained during continuous workloads such as virtualisation or database serving. The CL9 latency at 1333 MT/s delivers predictable throughput without the timing variance seen in unbuffered consumer DIMMs. All four sticks are tested together to ensure matched performance across every channel.

Pre-installation checks

Verify that your server model is one of the five ProLiant generations listed above and that the memory slots accept 240-pin registered ECC RDIMMs. This memory will not work in standard desktop boards and cannot be mixed with unbuffered modules. Confirm the system BIOS is current enough to recognise 8GB registered ranks before ordering.

Questions about this item

How much power does the 1.5 V DDR3 1333 kit draw under full load?

Each module runs at the standard 1.5 V JEDEC voltage for DDR3 1333. Total system draw depends on the server's memory controller and how many DIMM slots are populated.

What server hardware is required to use this ECC registered memory?

The kit is validated for HP ProLiant DL160 G6, DL165 G7, DL170e G6, DL170h G6 and DL180 G6. The motherboard must support DDR3 ECC registered DIMMs; unbuffered memory cannot be mixed with these modules.

Can the 2Rx4 registered DIMMs share channels with older unbuffered DDR3 sticks?

No. The manufacturer highlights state that ECC registered memory cannot be mixed with unbuffered memory. All populated slots should use matching registered modules for stable operation.
