Exact-fit server upgrade

This NEMIX RAM kit delivers 256GB of DDR5 memory as two 128GB registered ECC RDIMMs. It is built for administrators expanding a Supermicro X14SDV-42C-SP3F motherboard that requires 288-pin DDR5-5600 modules with 4Rx4 organisation and 1.10V operation. The exact rank, voltage and timing match the board's memory controller expectations for full-capacity recognition at rated speed.

Suited for validated platforms.

The kit suits operators who have confirmed their motherboard supports 256GB in this population order and need registered ECC stability for production workloads. Builders using consumer boards, unregistered DIMM slots, or systems that cannot accept 4Rx4 registered modules should look at something else because the registered interface and rank structure will not function there.

Registered ECC with 4Rx4 rank structure

Registered buffering offloads the memory controller so every slot runs fully populated at full capacity, while ECC corrects single-bit errors on the fly. The 4Rx4 organisation and CL46 timing at DDR5-5600 are the decisive specifications that determine whether this kit matches your motherboard's qualified-vendor list.

Questions about this item

How do I install the 288-pin RDIMM modules in my Supermicro X14SDV-42C-SP3F and which slot order should I follow?

Power down and unplug the server. Open the chassis and locate the DDR5 DIMM slots. Align each 288-pin RDIMM with the slot key, press straight down until both side clips click, and follow the motherboard manual's population sequence for 4Rx4 registered modules.

What maintenance or replacement will the 1.1 V DDR5 ECC RDIMM kit need over its service life?

No routine maintenance is required. The modules have no heat spreaders, so keep server airflow paths clean. ECC corrects single-bit errors on the fly; if uncorrectable errors appear in system logs, replace the affected 128 GB module.

What limit appears first when the 256 GB kit runs sustained workloads at 5600 MHz CL46?

The memory controller's maximum supported capacity and rank-per-channel limit for 4Rx4 registered DIMMs is reached before thermal throttling, capping usable bandwidth at the rated DDR5-5600 speed.
