Capacity and purpose

This kit provides 1 TB of DDR5 ECC registered memory in sixteen 64 GB modules. It is built for Supermicro Hyper SuperServer systems that require registered DIMMs with error correction.

Build and connectors

Each module is a 288-pin RDIMM organised as 2Rx4 and operates at 1.1 V without a heat spreader. The registered design adds a buffer that reduces electrical load on the server memory controller.

Compatibility check

Verify that your Supermicro SYS-121H-TNR, SYS-221H-TNR or SYS-221H-TN24R supports 16 populated DIMM slots at DDR5 4800 with CL40 timing. Confirm the platform accepts 2Rx4 registered modules before ordering.

Questions about this item

What DDR5 speed and PC5 rating do these 64 GB modules run at?

Each module runs at DDR5 4800, rated PC5-38400 with CL40 latency.

What physical slot and pin count do the 16 modules require?

They are 288-pin DDR5 RDIMMs that fit standard DDR5 RDIMM slots on the motherboard.

What is the correct order to populate the 16 DIMM slots on a SuperMicro Hyper SuperServer?

Follow the motherboard manual channel sequence; a common mistake is skipping a channel or mixing ranks instead of filling each channel identically.
