Server ECC Registered RDIMM

This 64 GB DDR4 module is built for Supermicro H11SSL-i, H11SSL-NC, H11SSW-iN, H12SSW-iN and H12DSG-O-CPU motherboards. It targets administrators upgrading workstations or servers that require registered ECC memory. The DIMM will not function in standard desktop platforms and cannot be mixed with unbuffered modules.

64 GB capacity at DDR4 3200

The single stick delivers 64 GB of PC4-25600 bandwidth with CL22 latency and 1.2 V operation. Two-rank 2Rx4 organisation provides density for memory-intensive workloads such as virtualisation or large databases. Systems limited to lower speeds will downclock the module, and boards without registered-ECC support will not recognise it at all.

Passive operation at 1.2 V

No heat spreader is fitted, so the module relies on chassis airflow for cooling. Registered buffering and ECC logic add minimal power overhead while maintaining signal integrity at 3200 MT/s. In typical server environments the DIMM runs silently and draws only the current required for its 1.2 V specification.

Perguntas sobre este artigo

Will this ECC Registered DDR4 module work alongside unbuffered DDR4 sticks already in my Supermicro board?

No, registered memory cannot be mixed with unbuffered modules; the board requires all slots to use registered DIMMs for stable operation.

How can I confirm the 64GB 3200MHz CL22 kit is running at its rated speed after installation?

Enter the BIOS or use a tool like dmidecode to verify the module reports DDR4 3200 PC4-25600 with CL22 timings at 1.2V.

Does the package include only the 288-pin RDIMM or are mounting brackets or cables also supplied?

Only the 64GB 288-pin DDR4 ECC Registered RDIMM is included; no brackets, cables or additional hardware are provided.
