32 GB DDR4-2933 ECC RDIMM for Dell PowerEdge R840

This registered DIMM delivers 32 GB of DDR4 memory at 2933 MT/s with CL21 latency and 1.2 V operation. It uses a 2Rx4 organisation and includes on-die ECC for data integrity in server workloads. The module is built for the Dell PowerEdge R840 rack platform.

Verify DDR4 RDIMM slots

Confirm the R840 has free 288-pin DDR4 RDIMM slots and that the system BIOS accepts 2933 MT/s registered ECC modules. Registered memory cannot be mixed with unbuffered DIMMs, so all installed modules must be registered. Check the server documentation for population rules and rank limits per channel.

Suits IT teams expanding R840 capacity

Buyers needing registered ECC memory for a Dell PowerEdge R840 will find this module tested for compatibility. It is not for desktop PCs, workstations requiring unbuffered DIMMs, or servers that only support lower DDR4 speeds or different form factors.
