Exact-fit DDR5 RDIMM for Supermicro X14SDV-20C-SP3F

This 32 GB DDR5 module runs at 4800 MT/s with CL40 timing and 1.10 V. It is a 2Rx8 registered ECC RDIMM built to match the Supermicro X14SDV-20C-SP3F motherboard's memory controller requirements for full capacity recognition.

DDR5 4800 registered ECC limits and population rules

The DDR5 4800 standard tops out at this data rate for registered DIMMs, and the board's memory population rules dictate which slots must be filled first. Exceeding the validated slot count or mixing ranks can prevent the system from booting at the rated speed.

Simple 288-pin RDIMM installation with manual checks

The 288-pin RDIMM seats like any registered module, but the board manual must be consulted for approved DIMM order and maximum supported capacity per channel. Skipping this step is the most common cause of unrecognised memory or reduced performance.

Questions about this item

Should I choose the 32GB 2Rx8 module or a different capacity for my Supermicro X14SDV-20C-SP3F?

This exact-match upgrade is a single 32GB DDR5-4800 2Rx8 Registered ECC RDIMM. Check your motherboard manual for supported capacities and the approved DIMM population order before purchase.

What does the DDR5-4800 PC5-38400 rating mean once installed in the server?

The module runs at 4800 MT/s with CL40 latency at 1.1V. Registered architecture offloads the memory controller so every slot runs fully populated at rated speed while ECC corrects single-bit errors on the fly.

How does the 288-pin RDIMM interface and registered design cap real-world use?

The 288-pin DDR5 RDIMM form factor fits only RDIMM slots — not UDIMM or SODIMM. Registered buffering lets the board run fully populated at full capacity, and ECC stops silent data corruption.
