SuperMicro DDR5 4800 ECC RDIMM kit

This 64GB kit contains four 16GB DDR5 4800 registered DIMMs built for SuperMicro FatTwin and SuperServer platforms. It targets administrators who need validated ECC memory for multi-node chassis.

Registered ECC at 4800 MT/s

Each module runs at PC5-38400 with CL40 latency, 1.10V voltage and a 1Rx8 organisation. The registered buffer and on-die ECC protect data integrity across the 288-pin DDR5 interface.

Four-module kit only

The package supplies exactly four matched sticks, so a single purchase populates four slots. Buyers needing a different capacity or a non-registered format must select another part.

Questions about this item

What does 4800 MT/s mean once the kit is installed in a SuperMicro server?

The modules run at DDR5-4800 with CL40 latency, giving the rated data rate when the platform trains them at that speed.

How does the PC5-38400 rating limit real-world throughput?

PC5-38400 is the JEDEC designation for DDR5-4800; the memory controller caps transfer rate to this standard.

What physical slot and clearance does the 288-pin RDIMM need?

Each 16 GB module uses a standard 288-pin DDR5 RDIMM form factor and has no heat spreader, so it fits any compatible SuperMicro DIMM slot.
