Exact-match 64 GB DDR5-6400 RDIMM

This 64 GB DDR5 6400 MHz module is built as a registered ECC RDIMM for the Supermicro X14SDW-42C-SP9F motherboard. It delivers 4Rx4 organisation at 1.1 V with CL52 timing so the memory controller recognises full capacity at rated speed.

Pre-installation checklist

Verify the motherboard manual for supported DIMM population order and maximum capacity per slot before ordering. Ensure the platform requires 288-pin registered DDR5 RDIMMs rather than unbuffered or SODIMM alternatives.

Build integration

Registered buffering offloads the memory controller, allowing every slot to run fully populated while on-die ECC corrects single-bit errors to prevent silent data corruption. The module fits directly into the board's DDR5 RDIMM slots with no heat spreader to clear.

Questions about this item

Does the box contain only the 64GB DDR5 6400MHz RDIMM or are cables or brackets included?

The package content lists the 64GB DDR5 6400MHz PC5-51200 4Rx4 1.1V 288-pin ECC RDIMM kit; no cables, brackets or additional accessories are mentioned.

Should I select the 64GB 4Rx4 CL52 module or a different rank for the Supermicro X14SDW-42C-SP9F?

This exact-match upgrade is spec-matched to the board's memory-population rules; the 4Rx4 organisation, 1.1V voltage and CL52 latency are what the controller expects for full-capacity recognition at rated speed.

What does the 6400MHz rating deliver once installed in the Supermicro X14SDW-42C-SP9F?

The module runs at DDR5 6400 (PC5-51200) with registered ECC architecture, so every populated slot operates at full capacity while ECC corrects single-bit errors on the fly.
