8GB DDR4 ECC RDIMM for servers

This 8GB DDR4 ECC Registered DIMM runs at 2133MHz with CL15 latency and 1.2V operation. It is built as a direct replacement for the Crucial CT8G4RFS4213 module. The single-rank 1Rx4 design suits server and workstation platforms that require registered ECC memory.

Verify DDR4 RDIMM support and slot count

Confirm that your system accepts DDR4 Registered ECC DIMMs before ordering. The module uses a 288-pin DIMM form factor and will not fit boards limited to UDIMM or SO-DIMM slots. Check the motherboard or server manual for maximum capacity per slot and total population rules.

Major-brand chips on a 288-pin registered stick

The PCB carries major-brand chipset components tested to A-Tech quality standards. Registered buffering reduces electrical load on the memory controller, allowing larger configurations in multi-socket servers. The 288-pin edge connector aligns with standard DDR4 RDIMM sockets for straightforward installation.
