A-Tech 48GB (6x8GB) DDR3 1600 ECC RDIMM 2Rx4 1.5V memory upgrade

Purpose-Built Server Memory

This 48GB kit contains six 8GB DDR3 registered DIMMs validated for Dell PowerEdge 12th generation rack servers including the R320, R420, R420xr, R520, R620, R720, R720xd, R820 and R920. It targets administrators who need ECC error correction and registered buffering for stable operation under sustained workloads. The modules are not compatible with desktop or laptop platforms that require unbuffered non-ECC memory.

Registered DIMM Construction

Each module uses a 240-pin DDR3 form factor with a 2Rx4 dual-rank organisation and major-brand chipsets. Registered buffering reduces electrical load on the server memory controller, allowing the full six-module population supported by these platforms. The absence of heat spreaders keeps the profile low for dense rack chassis while the 1.5V operating voltage matches the original server specification.

Thermals and Power in Operation

Running at DDR3 1600 (PC3-12800) with CL11 latency, the kit draws 1.5V per module under normal server loads. Registered DIMMs typically operate within standard server airflow designs without additional cooling. ECC functionality detects and corrects single-bit errors, helping maintain data integrity during continuous operation in the listed PowerEdge systems.
