Targeted server upgrade

This 32 GB kit delivers four 8 GB DDR4 registered DIMMs rated at 2133 MHz with CL15 timing and 1.2 V operation. It is built for HP ProLiant BL460c Gen9, DL160 Gen9 and DL180 Gen9 systems that require ECC error correction.

Registered 288 pin design

Each module uses a 288 pin registered layout with a 1Rx4 organisation, so the memory controller sees one electrical load per stick. The registered buffer improves signal integrity when all four slots per channel are populated in these Gen9 platforms.

Four stick kit only

The package contains exactly four matched DIMMs and no additional brackets, cables or software utilities. Buyers who need a different capacity per module or a non registered variant must select another part number.

Questions about this item

What DDR4 speed and PC4 rating do these registered DIMMs run at?

They operate at 2133 MHz with a PC4-17000 data rate, CL15 timing and 1.2 V.

Will the 288-pin modules fit the HP ProLiant BL460c Gen9, DL160 Gen9 and DL180 Gen9 servers?

Yes, the kit is validated for those three Gen9 systems and uses the standard 288-pin DDR4 DIMM form factor.

How should the four 8 GB sticks be populated for correct registered ECC operation?

Install all four modules in the matching coloured slots per CPU — typically sockets 1, 2, 3, 4 — so each channel receives one rank.
