256GB DDR5 ECC RDIMM kit

This 256GB kit contains eight 32GB DDR5 4800 registered ECC modules built for the SuperMicro X13SET-G and X13SET-GC motherboards. It targets administrators expanding memory capacity in compatible Supermicro server or workstation platforms.

DDR5 4800 registered ECC limits

The DDR5 4800 standard with registered ECC tops out at 4800 MT/s and CL40 latency on this platform, so bandwidth and error-correction overhead are fixed by the memory controller. Modules run at 1.1V without a heat spreader, leaving thermal headroom dependent on chassis airflow.

Eight 32GB modules fill every slot

Populating all slots with 1Rx4 288-pin RDIMMs delivers the full 256GB the board can address, giving headroom for large virtualisation or database workloads. Capacity stops at the platform maximum, so workloads needing more memory require a different motherboard or CPU architecture.

Questions about this item

Should I choose the 256GB kit with eight 32GB modules or a different capacity?

The kit provides 256GB total across eight 32GB DDR5 RDIMMs, giving maximum capacity for the SuperMicro X13SET-G and X13SET-GC platforms in a single matched set.

What does the 4800MHz speed mean once installed in a real server?

The modules run at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V, delivering the rated data rate and timing the motherboard expects for registered ECC operation.

How does the 288-pin DDR5 RDIMM interface affect what the system can use?

The 288-pin registered DDR5 form factor with ECC and 1Rx4 organisation is keyed for server motherboards only, so it fits and works in the X13SET-G and X13SET-GC but not in desktop boards.
