A-Tech 8GB DDR3 1333MHz ECC RDIMM 2Rx4 Server RAM

8GB DDR3 1333MHz ECC RDIMM

This A-Tech module delivers 8GB of DDR3 registered ECC memory at 1333MHz with CL9 latency. It operates at the standard 1.50V DDR3 voltage and uses a 2Rx4 rank configuration built on Samsung chipset. The 240-pin DIMM form factor targets servers and workstations requiring error-correcting registered memory for data integrity.

Sustained load behaviour

Registered ECC architecture adds a clock cycle of buffering to stabilise the command bus under continuous multi-threaded workloads. Error correction detects and corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. The 1.50V operating voltage keeps power draw predictable when all slots are populated in a dense chassis.

Upgrade context

This module replaces Samsung M392B1K70BM1-CH9, M392B1K70CM0-CH9 or M392B1K70DM0-CH9 sticks in compatible platforms. The jump is worthwhile when expanding capacity within an existing DDR3 registered memory subsystem or swapping failed modules. It does not suit systems that require unbuffered non-ECC DIMMs or a different DDR generation.
