64GB DDR4 2666 ECC RDIMM Module

This 64GB DDR4 2666 registered DIMM provides error-correcting memory for servers and workstations that require ECC protection. It operates at 1.20V with CL19 latency and uses a 288-pin form factor. The module is built with major-brand chips and 3DS/TSV packaging for high-density capacity.

Registered ECC Design and 288-Pin DIMM

Registered buffering reduces electrical load on the memory controller, allowing stable operation in multi-module server configurations. ECC functionality detects and corrects single-bit errors to protect data integrity. The 288-pin DIMM interface fits standard DDR4 server slots. Major-brand chipset components undergo quality-assurance testing for dependable performance.

2S2Rx4 3DS/TSV Rank Architecture

The 2S2Rx4 (4Rx4 3DS/TSV) rank structure delivers 64GB in a single module through 3D-stacked die technology. This high-density organisation suits platforms that support 3DS/TSV registered DIMMs. Systems without 3DS/TSV support will not recognise the full capacity.

Questions sur cet article

Does the DDR4 2666 interface cap real-world throughput at PC4-21300?

Yes, the module runs at DDR4 2666 MHz which corresponds to the PC4-21300 bandwidth rating; actual throughput will not exceed that specification.

What physical slot and pin count does this 288-pin RDIMM require?

It fits a standard DDR4 DIMM socket with 288 pins; the registered design adds a buffer chip so the motherboard must support registered ECC memory.

How is the module installed and which orientation step is most often missed?

Align the off-centre notch on the 288-pin edge connector with the key in the DDR4 slot, press straight down until both retention clips click, and verify the module sits evenly — the notch offset is the step most people get wrong.
