256 GB DDR5-5600 ECC RDIMM kit for Supermicro H13DSH

This 256 GB kit contains eight 32 GB DDR5-5600 registered ECC modules built to the exact rank, voltage and timing the Supermicro H13DSH memory controller expects. It targets administrators who need full-capacity population on this platform without compatibility guesswork.

Replaces mismatched or slower DDR5 RDIMMs

When existing modules differ in rank, voltage or CAS latency the controller may downclock the whole array or refuse to post; this kit eliminates that risk by matching the board's qualified specifications. The upgrade is worth it when you must run all slots at the rated 5600 MT/s with ECC protection active.

Verify DIMM population order

Server memory rules vary by CPU configuration and BIOS revision; consult the Supermicro H13DSH manual for approved slot sequences and per-channel limits before installing eight 2Rx8 modules. Confirm the board accepts 1.1 V registered DDR5 RDIMMs in a fully populated layout.

Questions about this item

Will the 288-pin RDIMM modules fit the DIMM slots on my Supermicro H13DSH motherboard?

Yes, the kit uses the 288-pin Registered RDIMM form factor that the H13DSH requires, so every module seats correctly in the board's DDR5 slots.

What is the correct population order when installing all eight 32GB modules?

Follow the motherboard manual's DIMM population sequence for the H13DSH; filling slots in the prescribed order ensures the memory controller recognises the full 256GB at 5600 speed.

Do these modules need any active cooling or heat spreaders over time?

The modules ship without heat spreaders and are rated for 1.10V operation; standard server chassis airflow is sufficient for continuous use.
