Capacity and Compatibility

This 16GB DDR3 module runs at 1066MHz with PC3-8500 rating and CL7 latency. It uses a registered ECC design with 4Rx4 organisation and operates at 1.50V. The 240-pin DIMM is built as a direct replacement for several Kingston server part numbers including KTM-SX310Q/16G and KVR1066D3Q4R7S/16G.

Build Integration

Registered ECC memory requires a server or workstation motherboard that supports buffered DIMMs and error correction. The single 16GB stick occupies one 240-pin slot and leaves remaining channels open for additional modules up to the platform limit. Standard 1.5V DDR3 voltage means no special power regulation is needed beyond what the board already provides.

Sustained Load Behaviour

ECC circuitry detects and corrects single-bit errors during continuous operation, preventing data corruption in long-running workloads. Registered buffering reduces electrical load on the memory controller, helping maintain signal integrity when multiple modules are populated. Major-brand chips and factory testing aim to deliver consistent throughput without throttling under extended use.

Questions about this item

How many ranks does the 16GB DDR3 1066MHz module present to the memory controller?

The module is organised as 4Rx4, meaning four ranks of x4 chips, so the memory controller sees four ranks per DIMM.

What voltage does the registered ECC DIMM draw when the server runs continuously?

It operates at the standard DDR3 voltage of 1.50V, so power draw stays at the normal level for DDR3 registered modules under sustained load.

Which motherboard slot type is required to install this 240-pin registered DIMM?

A DDR3 RDIMM socket with 240 pins is needed; the system must support registered ECC memory for the module to function.
