A-Tech 8GB DDR3 1333MHz PC3-10600 ECC RDIMM 2Rx4 Server Memory for IBM-Lenovo 0A89412 43X5056 46C7449

Server memory upgrade for IBM-Lenovo systems

This 8 GB DDR3 registered DIMM runs at 1333 MHz (PC3-10600) with CL9 latency and 1.50 V operation. It uses a 2Rx4 organisation and major-brand chips to provide ECC error correction for compatible servers and workstations. The 240-pin module replaces IBM-Lenovo part numbers 0A89412, 43X5056 and 46C7449.

Sustained load behaviour with ECC registered design

The registered buffer reduces electrical load on the memory controller, helping maintain signal integrity during continuous workloads. ECC circuitry detects and corrects single-bit errors on the fly, preventing data corruption over long runs. Major-brand chips are tested to meet server-grade reliability standards for 24/7 operation.

Thermals noise and power draw in normal use

Standard 1.50 V DDR3 voltage keeps power consumption within typical registered DIMM limits for this speed class. Passive cooling relies on chassis airflow; no moving parts are present on the module itself. The registered design adds minimal latency overhead while contributing to stable operation in densely populated memory slots.
