NEMIX RAM
32 GB DDR5 4800 ECC registered RDIMM, 2Rx8 CL40, 1.1 V, Hynix HMCG88MEBRA112N compatible
This 32 GB DDR5 4800 module is built for Hynix-compatible servers and workstations that require registered ECC memory. It runs at PC5-38400 with CL40 latency and a 1.1 V operating voltage. The 2Rx8 organisation suits multi-channel enterprise platforms.
The 288-pin RDIMM seats in standard DDR5 server DIMM slots without tools; the registered buffer ensures signal integrity on loaded channels. The only common issue is mixing registered and unbuffered modules, which prevents the system from posting. Always populate identical ranks per channel.
Confirm the motherboard or server manual lists DDR5 4800 RDIMM with ECC and 1.1 V operation. Systems that only accept unbuffered non-ECC UDIMMs will not recognise this module. Check the qualified vendor list for 2Rx8 32 GB parts to avoid compatibility errors.

The box contains one 32 GB 288-pin DDR5 RDIMM; no cables, brackets or additional components are needed beyond a compatible server or workstation motherboard with an empty DDR5 RDIMM slot.
This part is a single 32 GB 2Rx8 module; populate identical modules in matched channel pairs to enable dual-channel operation and maintain registered ECC integrity.
