Server memory upgrade

This 16GB DDR3 module is built for IBM-Lenovo systems that require the 90Y3157 part number. It targets administrators who need to add capacity to compatible servers or workstations running registered ECC memory.

Sustained workload behaviour

Registered signalling and ECC correction keep data integrity intact during continuous operation. The 1.50V standard voltage and CL11 latency deliver stable throughput for long-running server tasks without the errors that unbuffered memory can introduce.

Deciding specification

The 2Rx4 rank organisation determines whether this DIMM matches the memory controller requirements of the target system. Verify that your platform supports this exact rank configuration before ordering.

Questions about this item

How much power does the 1.50V DDR3 1600 registered ECC module draw when the server runs continuously?

At the standard DDR3 1.50V operating voltage this 16GB registered ECC DIMM draws only the power required by the memory controller for 1600MHz operation; registered buffering adds negligible overhead so heat output stays low during all-day workloads.

What motherboard slot and chipset support are required to install this 240-pin DDR3 RDIMM?

The module fits a standard 240-pin DDR3 DIMM socket and requires a server or workstation chipset that supports registered ECC memory at 1600MHz; desktop consumer chipsets typically do not enable ECC or registered operation.

Will this 2Rx4 PC3-12800 stick work alongside older 1Rx8 or 2Rx8 DDR3 modules already in my system?

Mixing ranks is often supported but the memory controller will run all populated slots at the lowest common speed and voltage; populate identical 2Rx4 modules in matched channels for best stability and full 1600MHz throughput.
