Exact-match DDR5 server kit

This 64 GB kit contains two 32 GB DDR5-5600 Registered ECC RDIMMs built to the 288-pin form factor. The modules run at 1.1 V with CL46 timing and a 2Rx8 organisation, matching the memory controller expectations of the Supermicro H13SSH-E motherboard. Registered buffering allows every slot to operate fully populated at rated speed while ECC corrects single-bit errors on the fly.

Upgrade from lower-capacity or slower DDR5 RDIMMs

Replacing smaller Registered ECC modules with this 64 GB kit doubles usable capacity per channel and keeps the native 5600 MT/s data rate. The jump is worth it when virtualization density, in-memory databases or large container workloads exceed the current memory ceiling and the platform already supports DDR5-5600 Registered DIMMs.

Fits Supermicro H13SSH-E memory slots

The 288-pin RDIMM form factor installs directly into the board's registered DIMM slots without adapters. Population rules in the motherboard manual dictate the installation order for full-capacity recognition. No heat spreader is present, so airflow across the module rows must be maintained by the server chassis cooling design. This kit does not suit systems that require unbuffered UDIMMs or SODIMM form factors.

Questions about this item

Will this 288-pin RDIMM kit fit the DIMM slots on my Supermicro H13SSH-E motherboard?

Yes, the kit uses the 288-pin DDR5 RDIMM form factor required by the Supermicro H13SSH-E, so the modules seat directly in its server DIMM slots.

What is the correct installation order for the two 32 GB modules on this board?

Consult the Supermicro H13SSH-E manual for the approved DIMM population sequence; installing in the wrong slots can prevent the system from recognising the full 64 GB capacity.

How do I know when a module in this ECC registered kit needs replacement?

The registered ECC design corrects single-bit errors automatically; watch the system logs for corrected-error counts or uncorrectable errors, which indicate a module should be swapped out.
