Server ECC DIMM for Fujitsu PRIMERGY

This 64GB DDR4 2666 CL19 4Rx4 ECC registered DIMM is built for Fujitsu PRIMERGY TX2550 M4, CX2560 M4, CX2570 M4, RX2530 M4 and RX2540 M4 servers and workstations. It replaces Fujitsu part numbers S26361F4026L764, S26361-F4026-L364, S26361F4026E764, S26361-F4026-E364 and S26361F4026E364.

Installation notes for registered ECC memory

The module uses a standard 288-pin DDR4 slot and operates at 1.2V. Because it is registered ECC, it will not work in standard desktop computers and cannot be mixed with unbuffered or load-reduced ECC modules. Backward compatibility with 2133MHz and 2400MHz systems is supported.

Capacity and rank that determine fit

The single 64GB 4Rx4 rank configuration is the critical specification; the server memory controller must support this density and organisation for the module to function.
