Exact-match server upgrade

This 256GB kit delivers four 64GB DDR5 5600 modules built to the PC5-44800 standard. Registered ECC RDIMMs with a 2Rx4 organization operate at 1.10V and CL46 timing. The modules match the precise rank, voltage and timing the Supermicro H14DST-FL memory controller expects for full-capacity recognition at rated speed.

For fully populated enterprise boards

Suited for administrators who need every slot filled with registered ECC memory on a validated Supermicro platform. Not intended for systems that accept only unbuffered UDIMMs or SODIMM form factors. Buyers who require a different capacity per module, a lower latency bin, or a non-registered architecture should look elsewhere.

Sustained-load stability

Registered buffering offloads the memory controller so all four slots run fully populated without signal degradation. On-die ECC corrects single-bit errors continuously, preventing silent data corruption during long compute runs. The 1.10V operating voltage keeps thermals steady under constant throughput, maintaining CL46 timing without throttling.

Questions about this item

What motherboard slot type must my Supermicro H14DST-FL have to accept this 288-pin DDR5 5600 RDIMM kit?

The board needs 288-pin DDR5 RDIMM slots; this kit is built for that exact form factor and will not fit UDIMM or SODIMM sockets.

How does the 2Rx4 registered ECC design of this 256 GB kit affect memory-controller load when all four DIMMs are populated?

Registered buffering offloads the controller so every slot runs fully populated at rated 5600 MT/s while ECC corrects single-bit errors on the fly.

Which BIOS indicators confirm the kit is running at its specified 5600 MT/s CL46 1.1 V settings after installation?

Check the memory information screen for DDR5-5600 frequency, CL46 timings, 1.1 V voltage, and the full 256 GB reported across all four channels.
