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.

Questions about this item
How much heat and power does this 1.50V DDR3 1333MHz registered module add when running continuously in a server?
At the standard 1.50V DDR3 voltage this 8GB registered DIMM draws typical DDR3 power and produces normal operating heat for a 1333MHz module; registered buffering adds slight load on the memory controller but no extra voltage is required.
What motherboard slot and system support are needed to install this 240-pin ECC RDIMM?
You need a server or workstation board with DDR3 240-pin DIMM slots that accept registered ECC memory and support PC3-10600 speed; the system BIOS must also enable ECC and registered operation.
Will this CL9 1333MHz registered stick work in a system that currently runs CL9 1333MHz unbuffered ECC modules?
No, registered and unbuffered ECC DIMMs cannot be mixed; the memory controller must be configured for registered operation, so all slots must use registered modules like this one.
