  • 4Rx4 quad-rank organisation fits high-density server slots
  • 5 V standard voltage ensures broad DDR3 platform compatibility

Server ECC RDIMM Upgrade

This 16 GB DDR3 registered DIMM brings error-correcting memory to compatible servers and workstations. The module runs at 1066 MHz with CL7 latency and a standard 1.50 V supply. It is built for systems that require registered, quad-rank x4 modules and cannot be used in desktop or laptop computers.

Thermals Noise Power Draw

Standard DDR3 voltage keeps power draw predictable for dense server configurations. Registered buffering reduces electrical load on the memory controller, helping maintain signal integrity under sustained workloads. No active cooling is included, so airflow within the chassis manages module temperature.

Quad Rank Configuration

The 4Rx4 organisation increases capacity per slot, letting administrators reach higher memory totals without populating every DIMM socket. Major-brand chips are tested for reliability before shipping. Compatibility must be verified against the system manual because registered ECC modules are not interchangeable with unbuffered or desktop memory.

Questions about this item

How do I install this 16GB DDR3 1066 ECC RDIMM in a server, and what step is often missed?

Power down the server, open the chassis, locate the 240-pin DDR3 DIMM slots, align the module's notch with the slot key, press firmly until both retention clips click, then consult the system manual for correct channel population order — skipping the manual's channel guide is the step most often missed.

What maintenance or replacement will this 1.5V registered module need over time?

No routine maintenance is required for the module itself; keep server air intakes clean to maintain cooling, and replace the unit only if memory diagnostics report uncorrectable ECC errors or the system fails to recognise the 16GB capacity at 1066 MHz.

What limit appears first when this quad-rank 4Rx4 RDIMM runs sustained workloads?

The memory controller's maximum supported rank count per channel is typically reached before thermal or bandwidth limits, so population rules in the system manual dictate how many 4Rx4 modules can be installed without down-clocking below 1066 MHz.
