Exact-Match Server Upgrade

This 32 GB DDR5 RDIMM is built to the precise rank, voltage and timing the Supermicro X14SDW-64C-SP9F memory controller expects. Registered ECC architecture lets every slot run fully populated at the rated 6400 MT/s speed without down-clocking.

Registered ECC Stability

The 2Rx4 registered design offloads the memory controller so all channels operate at full capacity while on-die ECC corrects single-bit errors on the fly. No heat spreader is fitted, relying on server chassis airflow for thermal management.

DDR5 Platform Limits

DDR5 6400 modules require a motherboard qualified for PC5-51200 speeds; this board accepts only 288-pin RDIMMs, not UDIMMs or SODIMMs. Population rules and maximum capacity per channel are defined in the system manual and must be verified before installation.

Questions about this item

Will the 2Rx4 registered ECC DIMMs need any firmware updates or re-seating after the initial install?

No firmware updates are required; the modules are spec-matched to the Supermicro X14SDW-64C-SP9F so the memory controller recognises them at full 32 GB capacity and 6400 MT/s on first boot.

What limit appears first when all channels stay populated at DDR5-6400 under continuous load?

The registered buffer and ECC logic keep every slot stable at the rated 1.10 V and CL52, so the first ceiling you hit is the motherboard's maximum supported capacity, not a speed or voltage throttle.

How much extra heat or power draw should I expect from these 288-pin RDIMMs running 24/7?

They operate at the standard DDR5 1.10 V with no heat spreader, so thermal output and power draw match the JEDEC baseline for 32 GB 2Rx4 registered modules at 6400 MT/s.
