256 GB DDR5 ECC RDIMM kit

This 256 GB kit contains two 128 GB DDR5 5600 registered ECC RDIMMs built for the Supermicro X14SDW-42C-SP9F motherboard. Each module runs at 1.1 V with CL46 latency and a 4Rx4 organisation. The registered design offloads the memory controller so every slot can be fully populated at rated speed.

Upgrading from smaller RDIMM sets

Replacing a lower-capacity RDIMM kit with this 256 GB set adds the headroom needed for large in-memory databases or virtualisation clusters. The jump is worth it when the workload exceeds the capacity of the existing modules and the board's population rules allow two 4Rx4 DIMMs per channel.

Build fit and requirements

The kit requires a motherboard that accepts 288-pin DDR5 RDIMMs and supports 4Rx4 registered ECC modules at 5600 MT/s. It frees the memory controller from address loading so the server can run fully populated without downclocking. Verify the system manual for approved DIMM population order before installation.

Questions sur cet article

Will the 288-pin DDR5 RDIMM modules fit the memory slots on my Supermicro X14SDW-42C-SP9F motherboard?

Yes, this kit uses the exact 288-pin Registered DDR5 form factor that the X14SDW-42C-SP9F requires. It is not a UDIMM or SODIMM, so it matches the board's physical slot keying.

What is the correct population order when installing both 128GB 4Rx4 modules, and what step is commonly missed?

Consult the motherboard manual for the approved DIMM population sequence; the step most often missed is verifying the specific slot order before seating both modules.

Do these 4Rx4 Registered ECC modules require any firmware updates or ongoing maintenance after installation?

No firmware updates are needed for the memory itself; the modules are sealed with no heat spreader and no moving parts, so they run maintenance-free once seated and recognised by the system BIOS.
