256GB DDR5 5600 ECC RDIMM kit

This 256GB kit contains two 128GB DDR5 5600 registered ECC modules built for the SuperMicro B13DEE motherboard. It targets administrators upgrading memory capacity in compatible Supermicro servers or workstations running demanding workloads.

Verify DDR5 RDIMM support and slot population rules

Before ordering, confirm the B13DEE board accepts DDR5 registered DIMMs at 5600 MT/s with a 4Rx4 organisation and 1.1V operation. Check the motherboard manual for approved population sequences, maximum per-channel capacity and any BIOS version requirements for this density.

Registered ECC modules for multi-socket server

These 288-pin RDIMMs provide error correction and signal buffering needed for stable operation in multi-processor Supermicro systems. They free standard unbuffered slots for other uses and allow the platform to address 256GB across two modules without exceeding registered-channel limits.

Questions about this item

What is included in the box and do I need to buy anything else?

The kit contains two 128 GB DDR5 5600 ECC RDIMM modules for a total of 256 GB. No extra cables or accessories are required — just install them in the SuperMicro B13DEE motherboard.

How do I choose between the listed versions or capacities?

This part number MR44800-744K2 is a single 256 GB kit (2 × 128 GB) running at DDR5 5600 with CL46 latency and 1.1 V. There are no alternative capacities or speeds under this MPN; select this kit when you need the full 256 GB registered ECC configuration.

What does the 5600 MT/s rating mean once the memory is installed in a real server?

The modules operate at DDR5 5600 (PC5-44800) with CL46 timing at 1.1 V. The SuperMicro B13DEE platform will run them at this rated speed provided the BIOS is current and all DIMM slots are populated according to the board’s memory population rules.
