A-Tech 4GB DDR3L 1333 ECC RDIMM 1Rx4 Server RAM

Server ECC RDIMM 4GB 1Rx4

This registered ECC module delivers 4GB of DDR3L memory for servers and workstations that require error correction and signal buffering. The single-rank 1Rx4 organisation suits systems that populate multiple slots per channel while maintaining stability. It replaces Micron MT18KDF51272PZ-1G4 and MT18KSF51272PZ-1G4M1 part numbers in qualified platforms. Builders needing non-ECC or unbuffered DIMMs should choose a different module type.

Low-voltage 1.35V DDR3L thermals

Operating at 1.35V instead of the standard 1.5V reduces power draw and heat output in densely populated memory banks. The DDR3L 1333 speed rating (PC3L-10600) keeps signalling within conservative margins, helping fan curves stay quiet under sustained workloads. Registered buffering adds minimal latency while lightening the electrical load on the memory controller. Modules run cooler than standard-voltage DDR3 equivalents in the same chassis.

240-pin DIMM registered build

The 240-pin DDR3 DIMM form factor fits server and workstation boards keyed for registered memory; it will not seat in desktop slots wired for unbuffered DIMMs. Major-brand chips and CL9 timing reflect factory validation for 24/7 operation in multi-socket systems. ECC circuitry corrects single-bit errors before they reach the OS, protecting data integrity in critical services. Verify the platform qualified vendor list before installation to confirm registered DIMM support.
