64GB DDR4 2400 ECC LRDIMM Server Module

This 64GB DDR4 2400MHz ECC Load Reduced DIMM is built for IBM-Lenovo servers and workstations that require registered memory with error correction. The single 288-pin module operates at 1.2V with a CAS latency of 17 and uses a 4Rx4 organisation. It is intended for administrators expanding memory capacity in compatible enterprise platforms.

Replaces IBM-Lenovo 00NV207 46W0841 46W0843

The module serves as a direct replacement for the listed IBM-Lenovo part numbers, allowing a capacity increase without changing the memory architecture. The upgrade is worthwhile when the system supports Load Reduced DIMMs at this speed and rank configuration, and when the workload demands more physical memory than the current population provides.

Sustained Load Behaviour with Major Brand Chips

Under continuous operation the major brand chipset and 1.2V operation help maintain stability across extended workloads typical of virtualisation or database tasks. Error correction detects and corrects single-bit errors in real time, while the load-reduced buffer reduces electrical loading on the memory controller during prolonged high-utilisation periods.

Questions about this item

Will this 288-pin DDR4 LRDIMM fit in my server's memory slots?

Yes, the module uses the standard 288-pin DDR4 DIMM form factor and operates at 1.2V, matching the physical and electrical requirements for compatible IBM-Lenovo systems.

What is the correct way to install this 4Rx4 ECC LRDIMM, and what step is often missed?

Align the notch with the slot key, press firmly until both retaining clips click shut, then verify in BIOS that the 64GB capacity and 2400MHz speed are recognised; skipping the BIOS check is the common oversight.

When will this 64GB DDR4 2400MHz module need replacement?

The memory itself has no scheduled replacement interval; it should last the life of the server unless a fault develops, in which case the lifetime warranty covers a replacement unit.
