64GB DDR4 3200 ECC RDIMM Server Module

This 64GB DDR4 3200 ECC RDIMM module uses a 2Rx4 registered design and runs at 1.20V standard voltage. It is built for server and workstation platforms that require error-correcting registered memory. The single DIMM delivers 64GB capacity in a 288-pin form factor.

Replaces IBM-Lenovo 02JG184 and related part numbers

The module serves as a direct replacement for IBM-Lenovo part numbers 02JG184, 02JG340, 4X71B67862, 4X77A08635, 4X77A12189 and 4ZC7A15124. The upgrade is worthwhile when the system supports DDR4 3200 registered ECC DIMMs and the workload demands higher capacity per slot. Verify the platform memory specification before purchase.

DDR4 3200 registered ECC practical limits

DDR4 3200 registered ECC memory operates at 1.2V with CL22 latency in this configuration. The registered buffer adds a clock cycle for address and command signals, which improves signal integrity at high densities. Maximum supported capacity and population rules are defined by the system memory controller and BIOS, not by the module alone.

Questions about this item

Will this 288-pin DDR4 module fit my server's registered DIMM slots?

The module uses the standard 288-pin DDR4 DIMM form factor for registered ECC memory, matching the physical slot keying used by compatible IBM-Lenovo systems.

Do I need to populate specific channels or slots when installing this 2Rx4 registered DIMM?

Install the module in the slot sequence recommended by your server's service guide; registered DIMMs often require a specific population order per channel to initialise correctly.

How do I know when this 64GB ECC RDIMM should be replaced?

Replace the module if the system logs uncorrectable ECC errors, fails memory diagnostics at boot, or shows persistent instability that testing isolates to this DIMM.
