512GB DDR5 ECC RDIMM Kit

This 512GB kit contains sixteen 32GB DDR5 4800 ECC registered DIMMs built for SuperMicro servers. The modules run at 1.1V with CL40 latency and use a 1Rx4 organisation. They are designed for the SYS-111C-NR, SYS-521C-NR and X13SEDW-F platforms.

Suited for memory-heavy server workloads

The 16-module layout fills every slot on supported SuperMicro motherboards. Builders who need fewer than 16 modules or a lower total capacity should choose a smaller kit. Systems that require unbuffered memory or a different pin count cannot use these registered DIMMs.

16-module count decides slot fit

Only boards with sixteen DDR5 RDIMM sockets can accept the full kit. A motherboard with fewer slots will leave modules unused and prevent the rated 512GB capacity. Verify the exact slot count before purchase.

Questions about this item

Does the 288-pin DDR5 RDIMM form factor fit the SuperMicro SYS-111C-NR and SYS-521C-NR chassis?

Yes, the 288-pin DDR5 RDIMM modules match the DIMM slots on the SuperMicro X13SEDW-F motherboard used in those servers.

What is the correct installation sequence for the 16 modules across the 16 DIMM slots?

Populate all 16 slots following the motherboard's channel order; the step often missed is seating each RDIMM until both ejector clips click locked.

When should the ECC registered modules be replaced under sustained server workloads?

Replace modules if ECC correctable-error counters climb steadily or if the system logs uncorrectable memory errors during POST.
