Computer Memory Solutions 64GB (2x32GB) DDR3L 1066 ECC Registered DIMM memory upgrade

Server-Specific DDR3L ECC Registered Memory

This 64GB kit delivers two 32GB DDR3L 1066MHz ECC registered DIMMs built for the Dell PowerEdge T420. Each module operates at 1.35V with CL7 timing and a 4Rx4 organisation. The registered design helps maintain signal integrity in multi-DIMM server configurations. Computer Memory Solutions guarantees compatibility with the listed system.

64GB Total Capacity Across Two Modules

The pair provides 64GB toward the T420 maximum of 384GB, using two of the twelve available sockets. Each 32GB stick is a 4Rx4 device; the platform requires like modules within each memory bank, so x4 and x8 parts must not be mixed in the same bank. Capacity scales by adding further matched kits in the remaining sockets. Headroom ends when all twelve sockets are populated with qualified modules.

240-Pin DIMM Form Factor for Direct Installation

The modules slot into the server's 240-pin DDR3 sockets without adapters or cable changes. Registered buffering and ECC functionality rely on the platform's memory controller, so no extra software configuration is needed. Using matched 4Rx4 modules in each bank keeps the memory subsystem stable and leaves the remaining sockets free for future expansion.
