NEMIX RAM
256 GB DDR5 server memory kit with two 128 GB registered ECC modules running at 5600 MHz CL46 1.1 V for Supermicro X14SDV-42C-SP3F motherboards
Size 256GB 2X128GB
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.
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 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.

Same family, different memory, cooler or clock — compare before you commit.
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.
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.
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.
