Exact-match server upgrade

This NEMIX RAM kit delivers 192GB of DDR5 memory in two 96GB modules, built to the 4800MHz PC5-38400 specification with CL40 latency and 1.1V operation. It targets administrators upgrading the Supermicro X14SDV-20C-SP3F motherboard where full-capacity recognition and rated speed depend on matching rank, voltage and timing precisely.

Registered ECC RDIMM form factor

Each 288-pin module uses a 2Rx4 registered architecture that buffers address and command signals, allowing every slot to run fully populated without overloading the memory controller. On-board ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots in production workloads.

Lifetime replacement and US support

The package contains only the two RDIMMs; no heat spreaders, cables or software utilities are included. NEMIX RAM backs the kit with a lifetime replacement warranty and free US-based technical support, so any compatibility question or module failure is handled directly without third-party escalation.

Questions about this item

What DDR5 speed does the PC5-38400 rating cap the 2x96GB kit at in practice?

The PC5-38400 rating locks the kit to DDR5 4800 MT/s, so the 192GB kit runs at 4800MHz as specified for the Supermicro X14SDV-20C-SP3F motherboard.

Which physical form factor and pin count must the Supermicro X14SDV-20C-SP3F board accept for these modules?

The board requires 288-pin DDR5 RDIMM modules; this 2x96GB kit matches that exact registered form factor and will not fit UDIMM or SODIMM slots.

How are the two 96GB RDIMMs installed on the Supermicro X14SDV-20C-SP3F, and what step do people often miss?

Follow the motherboard manual's DIMM population order for registered ECC memory; the common mistake is skipping the prescribed slot sequence, which prevents the full 192GB from being recognised at DDR5 4800.
