16GB DDR4 2666 ECC UDIMM for Servers

This 16GB DDR4 2666 ECC UDIMM module is built for servers and workstations that require error-correcting memory. It runs at PC4-21300 speed with a CAS latency of CL19 and operates at the standard 1.20V. The unbuffered 2Rx8 design fits 288-pin DIMM slots in compatible Dell platforms.

Major-brand chips tested for reliability

The module uses major-brand chipset components and undergoes quality-assurance testing to ensure dependable operation under sustained workloads. ECC functionality detects and corrects single-bit errors, protecting data integrity in critical applications. No additional software or accessories are bundled; the value comes from validated component selection and testing.

Simple DIMM installation with compatibility checks

Installation follows standard 288-pin DIMM procedures: align the notch, press firmly until the retention clips engage, and verify seating. The most common issue is purchasing ECC UDIMM for a system that requires registered (RDIMM) or load-reduced (LRDIMM) modules, which are physically similar but electrically incompatible. Always confirm your platform supports unbuffered ECC before ordering.

Questions sur cet article

Will the 16 GB DDR4 2666 ECC UDIMM need any maintenance or replacement under continuous operation?

The module is a solid-state component with no moving parts, so it requires no scheduled maintenance and has no defined replacement interval; it remains in service until a memory error or system upgrade prompts removal.

What limit appears first when the 2666 MHz CL19 1.2 V DIMM runs sustained workloads?

The DDR4 2666 speed rating and CL19 latency set the throughput ceiling, so bandwidth and access latency become the bottleneck before voltage or thermal limits are reached.

How much heat and power does the 288-pin ECC UDIMM produce during all-day use?

At the standard 1.2 V DDR4 voltage the module draws minimal power and generates little heat, staying within normal DIMM thermal envelopes without active cooling.
