64GB DDR4 2133 ECC LRDIMM

This 64GB DDR4 2133 ECC LRDIMM module targets server and workstation operators who need maximum capacity per slot. The 4Rx4 load-reduced design allows dense memory configurations on platforms that support LRDIMM architecture. It replaces HP part 839051-001 for compatible systems.

Upgrade path from lower-capacity RDIMMs

The jump is worthwhile when your workload exceeds the rank or capacity limits of standard registered DIMMs and your motherboard qualifies LRDIMM at 2133 MT/s. If the platform only accepts RDIMM or caps speed below 2133, this module will not provide the expected benefit.

288-pin DIMM installation

Installation follows standard DIMM alignment; the 288-pin keying prevents incorrect insertion. The common issue is mixing LRDIMM with RDIMM in the same channel or populating slots in an order the firmware does not support, which leads to a no-post condition.

Questions sur cet article

Will the 288-pin DIMM fit my server's memory slots?

This module uses the standard DDR4 288-pin DIMM form factor. Verify your system accepts DDR4 LRDIMMs before purchase.

Do I need to configure anything in BIOS after installing this 4Rx4 LRDIMM?

Install the module with the system powered off. Most servers detect DDR4 2133 ECC LRDIMM automatically; check the memory configuration screen to confirm 64 GB at 2133 MHz.

When should this 64 GB ECC module be replaced?

Replace the module if the system logs uncorrectable ECC errors, corrected-error thresholds are exceeded, or the DIMM fails to initialise during POST.
