512GB DDR5 ECC RDIMM kit for Supermicro servers

This 512GB kit contains eight 64GB DDR5 4800 CL40 registered DIMMs built for Supermicro Hyper SuperServer systems. It targets administrators who need maximum registered ECC capacity in validated 288-pin modules. The modules operate at 1.1V with 2Rx4 organisation using major OEM DRAM.

DDR5 4800 registered ECC requires platform support

The memory runs at PC5-38400 with CL40 latency and registered buffering. Systems must implement DDR5 RDIMM electrical specifications and ECC error correction at the memory controller. Mixed-rank or unbuffered populations are not supported by this module design.

Verify Supermicro model qualification

Confirm the target chassis is a SYS-121H-TNR, SYS-221H-TNR or SYS-221H-TN24R before ordering. Check the motherboard manual for maximum DIMMs per channel, required population order and any BIOS version minimums for 64GB dual-rank modules. Ensure all eight slots in the configured channels are available and keyed for 288-pin DDR5 RDIMMs.

Questions about this item

How should I choose between the 8-module kit and smaller capacities?

This kit provides eight 64 GB modules for a total of 512 GB; if your Supermicro server has fewer than 24 DIMM slots you would need a smaller kit.

What does the DDR5 4800 rating mean once the modules are installed in a Supermicro Hyper SuperServer?

The modules will run at 4800 MT/s with CL40 latency at 1.10 V, delivering the rated PC5-38400 bandwidth in the supported SYS-121H-TNR, SYS-221H-TNR or SYS-221H-TN24R platforms.

What does the 288-pin RDIMM interface cap in practice?

The 288-pin registered DDR5 form factor limits each module to 64 GB and requires a motherboard that supports ECC registered memory; it will not fit standard UDIMM slots.
