AXIOM 64GB DDR4-2666 ECC LRDIMM

This 64GB DDR4-2666 ECC LRDIMM module is built for Dell PowerEdge R640 and R940 servers requiring registered memory with error correction. It operates at 1.20V with CL19 latency and conforms to the PC4-21300 standard. The 288-pin form factor fits compatible DDR4 slots in these specific enterprise platforms.

ECC and LRDIMM architecture

Error Checking and Correcting logic detects and corrects single-bit errors to protect data integrity in critical workloads. The Load-Reduced DIMM design reduces electrical load on the memory bus, allowing higher density per channel. RoHS certification confirms compliance with hazardous substance restrictions for environmentally responsible deployment.

Installation and compatibility notes

Installation follows standard DIMM seating procedures for 288-pin DDR4 slots in the validated Dell PowerEdge R640 and R940 systems. Compatibility is limited to the listed server models; other platforms may not recognise the module or may operate at reduced speeds. Verify the exact part number SNP4JMGMC/64G against your service manual before ordering.

Questions about this item

Will the 64GB DDR4-2666 ECC LRDIMM require any scheduled maintenance or component replacement during its service life?

The module has no moving parts and carries a lifetime warranty, so no scheduled maintenance or replacement is expected under normal operation.

What limit appears first when the 288-pin LRDIMM runs at 2666 MHz continuously in a PowerEdge R640 or R940?

The CAS latency of CL19 at 1.20 V sets the timing boundary that the memory controller reaches before any thermal or power ceiling.

How much heat and noise does the 64GB DDR4 LRDIMM produce when installed in a Dell server running all day?

The stick draws 1.20 V with no onboard fan, so it adds only passive heat to the server’s existing airflow and generates no audible noise of its own.
