Targeted Server Upgrade

This 64 GB kit delivers two 32 GB DDR4 2133 MHz ECC registered DIMMs built for HP ProLiant BL460c Gen9, DL160 Gen9 and DL180 Gen9 systems. It adds 512 GB maximum registered ECC capacity across 16 sockets when two CPUs are installed, using 2Rx4 organisation at 1.2 V with CL15 timing.

Registered ECC Replacement

The modules replace non-ECC or unbuffered memory that cannot meet the platform's error-correction and signal-integrity requirements. The jump is worth it when workloads demand data integrity across all 8 sockets per CPU and the board calls for PC4 17000 registered DIMMs.

Sustained Load Behaviour

Under continuous operation the registered design reduces electrical load on the memory controller while ECC corrects single-bit errors in real time. The 15-15-15 timing and 1.2 V voltage maintain stable throughput during extended compute tasks without exceeding the platform's thermal envelope.

Questions about this item

Will these 288-pin DDR4 DIMMs fit the 16 DIMM slots in a dual-CPU ProLiant DL160 Gen9?

Yes, the kit provides two 32 GB registered DIMMs for the 288-pin DDR4 slots; the DL160 Gen9 supports up to 16 sockets across two CPUs, so they install directly.

What is the correct slot population order when adding this 2Rx4 registered memory to a ProLiant BL460c Gen9?

Populate the lowest-numbered white DIMM slot for each CPU first, then continue sequentially; the common error is skipping a slot or mixing registered with unbuffered modules.

How can I verify the modules are still healthy after deployment?

Run the HPE Smart Memory diagnostics in the iLO interface or UEFI; they report corrected error counts and will flag a 32 GB DIMM for replacement if thresholds are exceeded.
