Server memory upgrade for legacy platforms

This 16GB DDR3 1066 module uses a 240-pin RDIMM form factor with registered ECC and a 4Rx4 organisation. It operates at the standard 1.5V voltage with CL7 latency. The part is built as a direct replacement for several IBM-Lenovo server part numbers.

Fits registered DDR3 slots only

The module requires a motherboard that supports registered ECC DDR3 DIMMs and cannot be used in unbuffered desktop slots. Each stick occupies a single 240-pin socket and presents four ranks to the memory controller. Builders must confirm their platform accepts 4Rx4 registered modules before installation.

Steady throughput under constant load

Registered buffering and ECC correction maintain data integrity during extended server workloads. The CL7 timing at 1066MHz delivers consistent bandwidth for multi-threaded applications that run for hours. Modules are tested to sustain operation without the errors that can accumulate in non-ECC memory under similar pressure.

Preguntas sobre este artículo

How does the 4Rx4 rank configuration affect sustained memory throughput on this DDR3 1066 module?

The 4Rx4 organisation places four ranks on a single DIMM, so the memory controller must interleave more rank-to-rank switches during long workloads, which can become the first throughput limit under sustained use.

What thermal or acoustic impact should I expect when this 1.5 V registered ECC DIMM runs continuously in a server chassis?

Registered DDR3 modules at 1.5 V draw modest power and have no active cooling; in a properly ventilated server they add negligible heat and produce no audible noise of their own.

Which existing system component must already support 240-pin DDR3 registered ECC memory for this 16 GB module to function?

The motherboard and CPU memory controller must both accept 240-pin DDR3 RDIMMs with ECC; without that support the module will not be recognised or will fail to boot.
