Targeted server upgrade

This 64GB kit contains four 16GB DDR4 registered DIMMs built for HP ProLiant BL460c Gen9, DL160 Gen9 and DL180 Gen9 systems. It delivers ECC error correction and registered signalling at 2133MHz for stable operation in multi-socket platforms. The modules run at 1.2V with CL15 timing and a 2Rx4 organisation. Buyers needing non-ECC or unbuffered memory for workstations should look elsewhere.

Four-module kit

The package supplies four matched sticks so the server can populate identical channels across one or two CPUs. Registered buffering reduces electrical load on the memory controller, allowing larger configurations than unbuffered alternatives. ECC protection corrects single-bit errors and detects multi-bit faults without extra software. No heat spreaders are included, relying on chassis airflow instead.

Capacity and headroom

Each CPU supports up to 512GB of registered ECC RDIMMs across eight sockets, so this 64GB kit leaves ample room for future expansion. The 2133MHz speed matches the platform's native memory bus, avoiding down-clocking penalties. Systems that require load-reduced DIMMs beyond 512GB per CPU cannot use these modules.

Questions about this item

Will the 288-pin DDR4 DIMMs need any firmware updates or re-seating after extended server operation?

The modules are registered ECC DDR4 with a 1.2 V rating and CL15 timing; no firmware is required and the lifetime warranty from Computer Memory Solutions covers defects.

What capacity ceiling will the ProLiant BL460c Gen9 hit first when all four 16 GB sticks are installed?

Each CPU accepts eight registered DIMM sockets for a maximum of 512 GB, so the 64 GB kit leaves ample headroom before the platform limit is reached.

How much extra heat or power draw should I expect from the 2133 MHz registered kit running continuously in a DL160 Gen9?

At 1.2 V and CL15 the sticks run at standard DDR4 voltage with no heat spreader, so thermal and power impact matches typical registered DIMM loads for this platform.
