Server DDR5 RDIMM upgrade

This 64GB DDR5 6400MHz module is a registered ECC RDIMM built for the Supermicro X14SDV-42C-SP3F motherboard. It runs at 1.1V with CL52 latency and a 4Rx4 rank layout. The 288-pin form factor matches the board's memory slots exactly.

Suited for populated Supermicro servers

It fits administrators expanding a Supermicro X14SDV-42C-SP3F system that requires registered ECC memory at this speed and rank. Builders needing UDIMM, SODIMM, non-ECC, or a different voltage should look at other memory types.

Verified Supermicro X14SDV-42C-SP3F compatibility

The module is validated for the Supermicro X14SDV-42C-SP3F motherboard at DDR5 6400 PC5-51200 with 4Rx4 registered ECC operation. Check your system manual for supported capacities and DIMM population order before installing.

Questions about this item

Does the Supermicro X14SDV-42C-SP3F motherboard need a specific DIMM population order for this 64GB 4Rx4 DDR5-6400 RDIMM?

The motherboard manual lists the supported capacities, approved DIMM population order, and installation steps; follow that guide so the memory controller recognises the 64GB module at its rated 6400 MT/s speed.

Can I add this 64GB 4Rx4 DDR5-6400 RDIMM alongside existing DDR5 registered modules of a different rank or speed?

Mixing ranks or speeds forces the memory controller to run all slots at the lowest common speed and may prevent full-capacity operation; populate every slot with identical 4Rx4 DDR5-6400 modules for guaranteed stability.

How can I confirm the module is running at DDR5-6400 with CL52 and ECC active after installation?

Check the BIOS memory information or use a tool such as dmidecode to verify the reported speed 6400 MT/s, CAS latency 52, voltage 1.1 V, and that ECC is shown as enabled.
