32GB DDR4 2133MHz ECC LRDIMM for Servers

This 32GB module uses DDR4 2133MHz with CL15 latency and 1.2V operation. It is built as an ECC Load Reduced DIMM in a 4Rx4 configuration on major brand chips. The 288-pin form factor fits server and workstation platforms that require registered memory with error correction.

Replaces Dell 370-ABUH and matching part numbers

The module is a compatible equivalent for Dell part numbers including 370-ABUH, 370-ABUL, 370-ABXL, A7910489, A7945725, MMRR9, SNP2133D4L15/32G, SNPMMRR9C/32G and SNPPR5D1G/32G. The upgrade is worthwhile when a system needs higher capacity per slot or when replacing failed modules in qualified Dell servers and workstations.

Installs in standard 288-pin DDR4 DIMM slots

Installation follows normal server memory procedures: power down, open the chassis, align the notch and press until the latches lock. The most common issue is mixing LRDIMM with standard RDIMM or UDIMM in the same channel, which prevents the system from posting. Verify the platform supports Load Reduced memory before fitting.

Questions about this item

Does the 288-pin DDR4 DIMM fit a standard server LRDIMM slot?

Yes, the module uses the 288-pin DDR4 DIMM form factor required for LRDIMM slots in compatible Dell servers.

What is the correct way to seat the LRDIMM so the ECC and load-reduced features initialise?

Align the notch with the slot key, press straight down until both side clips click, then verify 1.2 V operation in BIOS.

When should the 32 GB CL15 module be replaced to maintain ECC reliability?

Replace if the system logs recurring correctable ECC errors or fails memory diagnostics during scheduled maintenance.
