Server memory for Dell systems

This 64 GB DDR4 2666 module is built as a load-reduced ECC DIMM for Dell servers and workstations. It replaces part numbers such as 370-ADNH, 370-ADNT and 370-ADOX in compatible platforms. The single stick adds high-density capacity without occupying additional slots. Systems needing registered ECC memory at this speed can use it directly.

Thermals and power in normal use

Operating at the standard DDR4 voltage of 1.20 V, the module draws minimal power for its density. Load-reduced buffering reduces electrical load on the memory bus, helping keep temperatures stable under sustained workloads. No active cooling is required beyond normal server airflow. The CL19 latency supports consistent timing during extended operations.

The specification that decides fit

The 4Rx4 rank organisation determines whether the memory controller can address the full 64 GB capacity. Verify that your Dell system supports quad-rank load-reduced DIMMs before purchase. The 288-pin DDR4 form factor fits only DDR4 slots, not earlier or later generations. Compatibility depends on this rank structure and the ECC LRDIMM type.

Otázky k tomuto produktu

How do I install this 288-pin DDR4 LRDIMM and what step is often missed?

Align the notch with the slot key, press firmly until both latches click, then verify the server BIOS recognises the full 64GB capacity and ECC mode at 2666MHz.

What maintenance or replacement will this 4Rx4 module need over time?

No routine maintenance is required; the module either passes POST and runs indefinitely or fails and must be replaced as a single 64GB unit.

What limit appears first when this CL19 1.20V kit runs sustained workloads?

The memory controller’s maximum supported rank count per channel is reached before thermal or voltage limits become an issue.
