  • Validated for SuperMicro CloudDC SuperServer platforms

Capacity and Compatibility

This 64GB kit contains two 32GB DDR5 4800 modules built for SuperMicro CloudDC SuperServer systems including the SYS-621C-TN12R, SYS-611C-TN4R and SYS-121C-TN2R. It targets administrators who need registered ECC memory for those specific platforms.

Registered ECC Requirement

The modules are 288-pin DDR5 RDIMMs with a 1Rx4 organisation, CL40 latency and 1.1V operation. They will only work in motherboards that support registered ECC DDR5 at this speed and rank configuration; standard desktop boards cannot use them.

Kit Contents

The package supplies the two 32GB modules as a matched pair with no heat spreaders, cables, software or additional accessories included. Buyers who need cooling solutions or diagnostic tools must source those separately.

Questions about this item

What does the 4800 MT/s speed mean once the modules are installed in a SuperMicro server?

The kit runs at DDR5 4800 (PC5-38400) with CL40 latency, delivering the rated throughput as long as the platform memory controller supports that data rate.

What does the ECC RDIMM interface cap in practice on these modules?

Registered ECC operation with 1Rx4 organisation at 1.1 V; the 288-pin DDR5 RDIMM form factor limits use to platforms that accept registered DDR5 DIMMs.

What physical clearance does the 288-pin DDR5 RDIMM need to fit in the SYS-621C-TN12R?

Standard 288-pin DDR5 RDIMM height with no heat spreader; the modules occupy two DIMM slots and require the server's native DDR5 RDIMM socket spacing.
