128GB DDR5-5600 ECC RDIMM kit

This 128GB kit contains four 32GB DDR5-5600 Registered ECC RDIMMs built for the Supermicro X14SDV-32C-SP3F motherboard. It delivers 5600 MT/s at CL46 with a 1.1V operating voltage and 2Rx8 organisation. The registered buffer and on-die ECC protect data integrity in fully populated server configurations.

Check motherboard manual before ordering

Verify that your Supermicro X14SDV-32C-SP3F revision supports 128GB total capacity and the approved DIMM population sequence for four 288-pin RDIMMs. Confirm the BIOS recognises 2Rx8 registered modules at DDR5-5600 and that no firmware update is required for full-speed operation. Ensure the chassis provides clearance for standard-height RDIMMs without a heat spreader.

Upgrades from lower-capacity DDR5 RDIMMs

Replacing smaller DDR5 RDIMM kits with this 4x32GB set doubles or quadruples usable memory while keeping the same 5600 MT/s CL46 timing and 1.1V profile. The jump is worth it when workloads exceed current capacity and the board's population rules allow four registered DIMMs. It does not fit systems limited to UDIMM, SODIMM or earlier DDR generations.

Questions about this item

What comes in the box and is anything else needed for installation?

The kit includes four 32 GB DDR5-5600 2Rx8 registered ECC RDIMMs, part number MR44800-328K4. No additional parts are required; install them directly into the 288-pin slots following the motherboard manual population order.

Should I choose a different capacity or speed for the Supermicro X14SDV-32C-SP3F?

This 128 GB (4 x 32 GB) kit matches the board's DDR5-5600 PC5-44800 specification, 2Rx8 registered ECC, 1.1 V, CL46. Other capacities or speeds may not be supported or could run at reduced performance.

What does the DDR5-5600 CL46 rating mean once the modules are running in the server?

The memory controller will operate the kit at 5600 MT/s with a CAS latency of 46 cycles at 1.1 V. Registered buffering and ECC keep all four slots stable at full capacity while correcting single-bit errors automatically.
