288GB DDR5 ECC RDIMM kit for Supermicro H13SST-G

This 288GB kit contains six 48GB DDR5 4800MHz PC5-38400 registered ECC RDIMMs built to the exact rank, voltage and timing the Supermicro H13SST-G motherboard expects. The 2Rx8 modules operate at 1.1V with CL40 latency and install in the board's 288-pin RDIMM slots.

Upgrade from smaller or slower DDR5 kits

Replacing a lower-capacity or mixed-speed DDR5 kit with this matched 6x48GB set lets the memory controller run every slot at the rated 4800MHz without downclocking. The jump is worth it when your workloads need the full 288GB capacity and the stability of registered ECC across all channels.

Check motherboard population rules and DIMM slots

Verify the H13SST-G manual for approved DIMM population order, maximum supported capacity per slot and any BIOS version requirements before ordering. Confirm the system uses 288-pin RDIMM slots and that the board's memory controller supports 2Rx8 registered modules at 1.1V.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the Supermicro H13SST-G memory slots?

Yes, the kit uses the 288-pin RDIMM form factor that the H13SST-G requires; it is not a UDIMM or SODIMM.

What population order should I follow when installing the six 48 GB modules on the H13SST-G?

Check your motherboard manual for the approved DIMM population sequence before installing all six modules.

Do these registered ECC modules need any firmware updates or ongoing maintenance after installation?

No firmware updates are required; the ECC function corrects single-bit errors automatically during normal operation.
