NEMIX RAM
A 16 GB DDR4 3200 UDIMM with CL22 latency and 1.2 V operation for compatible Hynix systems
This 16 GB DDR4 module runs at 3200 MHz with CL22 latency and 1.20 V. It is built as a 2Rx8 unbuffered non-ECC UDIMM for desktop PCs and workstations that use Hynix-compatible memory. The single stick upgrades one slot without requiring registered or ECC support.
The bare 288-pin PCB fits standard DDR4 DIMM sockets and keeps a low profile for tight clearance around large CPU coolers. Unbuffered operation means the memory controller talks directly to the chips, so the board must support non-ECC unbuffered UDIMMs. No heat spreader is included, so airflow over the modules is relied on for cooling.
Check that the motherboard or system lists DDR4 3200 (PC4-25600) and accepts 2Rx8 non-ECC unbuffered UDIMMs. Some platforms cap rank count per channel or require specific population rules for dual-channel operation. Confirm the slot count and maximum capacity per slot before ordering.
