Server DDR4 ECC Registered module

This 64 GB DDR4 DIMM is built for enterprise servers and workstations that require registered, error-correcting memory. It operates at 2666 MHz with a CL19 latency profile and runs at the standard 1.20 V. The dual-rank 2Rx4 organisation fits 288-pin DDR4 slots in compatible platforms.

Registered signal and ECC support

Registered buffering reduces electrical load on the memory controller, allowing higher module counts per channel. ECC detects and corrects single-bit errors, protecting data integrity in mission-critical workloads. The CL19 timing at 2666 MHz meets the PC4-21300 specification for stable throughput.

Single 64 GB stick for density

Supplied as a single 64 GB module, it maximises capacity per slot and simplifies population rules on boards with limited DIMM sockets. No additional accessories, cables or software licences are included in the package.

Perguntas sobre este artigo

How does 64 GB in a single 2Rx4 module behave in a real server?

The dual-rank 2Rx4 organisation lets the memory controller interleave across ranks inside one DIMM, so a single 64 GB stick can keep all channels populated without sacrificing density.

What does the DDR4-2666/PC4-21300 rating limit in practice?

The module is specified at 2666 MT/s with CL19-19-19 timing; the registered buffer adds one cycle of address/command delay, so sustained bandwidth tops out at the PC4-21300 ceiling.

What physical slot and keying does the 288-pin DIMM need?

It plugs into a standard 288-pin DDR4 RDIMM socket with the DDR4 notch position; the registered buffer and 1.20 V operation are handled by the slot’s wiring.
