Exact-match server upgrade

This 256GB kit delivers two 128GB DDR5 5600 RDIMM modules built to the Supermicro X14SDW-64C-SP9F memory controller specification. Registered ECC architecture with 4Rx4 organisation and CL46 timing at 1.1V ensures the board recognises full capacity at rated speed without manual tuning.

256GB registered ECC headroom

Dual-rank 4Rx4 density lets the platform address the full 256GB across two slots while ECC corrects single-bit errors on the fly. Registered buffering offloads the controller so every populated slot runs at 5600 MT/s, though total capacity is capped at the two-module kit and the board's maximum supported population.

288-pin RDIMM form factor

Modules use the standard 288-pin Registered DIMM keying required by the target motherboard, not UDIMM or SODIMM layouts. No heat spreader is fitted, so airflow in dense server chassis passes directly over the DRAM packages for consistent thermal behaviour under sustained load.

Questions about this item

Will these 4Rx4 DDR5-5600 RDIMMs run at full speed alongside older DDR5-4800 modules already in my Supermicro X14SDW-64C-SP9F?

The kit is spec-matched to the board's DDR5-5600 (PC5-44800) memory controller. Mixing with DDR5-4800 modules will force the system to run all slots at the lower 4800 MT/s speed and may violate the motherboard's population rules for registered ECC DIMMs.

How can I confirm the 256 GB kit is detected at DDR5-5600 CL46 with ECC active after installation?

Enter the BIOS/UEFI on the Supermicro X14SDW-64C-SP9F and verify the memory information screen shows 256 GB total, DDR5-5600 (PC5-44800) data rate, CL46 timings, 1.10 V voltage, and ECC enabled for each of the two 128 GB 4Rx4 RDIMMs.

What exactly ships in the box and do I need any extra brackets or cables for the Supermicro X14SDW-64C-SP9F?

The package contains only the two 128 GB 288-pin DDR5-5600 ECC Registered RDIMMs. No heat spreaders, brackets, cables or additional hardware are included; the modules install directly into the motherboard's DDR5 RDIMM slots.
