NEMIX RAM
8 GB DDR4 ECC registered DIMM running at 2400 MHz with CL17 latency and 1.2 V operation
This 8GB DDR4 2400 module is a registered ECC RDIMM built for Samsung server and workstation platforms. It uses Samsung, Micron or Hynix chips and runs at 1.2V with a CL17 latency. The 2Rx8 organisation suits systems that require registered memory with error correction.
The 288-pin DDR4 RDIMM inserts like standard memory but must go into slots that support registered ECC modules. Common issues include mixing registered and unbuffered DIMMs or populating slots in an order the motherboard firmware rejects. Always follow the system manual for slot population rules.
Confirm your Samsung motherboard accepts DDR4 2400 registered ECC RDIMMs and that the BIOS is current enough for 2Rx8 modules. Systems limited to unbuffered non-ECC memory or to lower voltages will not POST with this module. Check the qualified vendor list for the exact part number.
