16GB DDR4 2666 ECC RDIMM for Servers

This 16GB DDR4 2666MHz registered DIMM targets administrators upgrading or repairing enterprise servers and workstations that require error-correcting memory. The module delivers 16GB of capacity in a single 288-pin stick, operating at the standard 1.20V DDR4 voltage for broad platform compatibility.

Registered ECC with 2Rx4 Organization

The defining specification is the registered ECC design with a 2Rx4 rank configuration, which enables the module to work in multi-DIMM server channels that demand registered signalling and error correction. Systems requiring unbuffered non-ECC UDIMMs or a different rank layout will not accept this part, so verifying the motherboard's qualified vendor list is essential before purchase.

Major-Brand Chips and Micron Cross-Reference

The module uses major-brand DRAM chips and is validated as a compatible equivalent for the Micron MTA36ASF2G72PZ-2G6E1 part number, giving buyers a direct cross-reference for procurement lists. No extra software, heatsinks or cables are bundled; the value lies in the component-level quality assurance and the lifetime warranty that covers the memory itself.

Perguntas sobre este artigo

What does the DDR4 2666 speed mean for real-world server performance?

The DDR4 2666 rating shows the module transfers data at 2666 MT/s. Actual throughput depends on the CPU memory controller, channel population and BIOS settings, so measured bandwidth will vary by platform.

How does the ECC RDIMM interface affect error correction and capacity limits?

The registered DIMM adds a register between the DRAM and the memory controller, reducing electrical load so the system can support more modules per channel. ECC detects and corrects single-bit errors and detects multi-bit errors, improving data integrity for server workloads.

What physical slot and clearance does this 288-pin module require?

It fits a standard DDR4 DIMM socket with 288 pins and 1.2 V operation. The registered design uses the same keying as unbuffered DDR4 DIMMs, but the system must explicitly support RDIMM; UDIMM-only boards will not accept it.
