NEMIX RAM MR38400-9624K4 384GB (4x96GB) DDR5 4800 CL40 2Rx4 ECC RDIMM memory upgrade

384GB DDR5 4800 ECC RDIMM kit

This 384GB kit contains four 96GB DDR5 4800 Registered ECC RDIMMs built for the ASRock Rack GENOA2D24G-2L+ motherboard. It targets administrators who need maximum supported capacity in a validated configuration. Each module runs at 1.1V with CL40 timing and a 2Rx4 organisation. The registered design allows full population of every slot at rated speed.

DDR5 4800 interface limits

DDR5 4800 sets the maximum data rate the memory controller can use with this kit; the modules will not run faster than 4800 MT/s on this platform. Registered buffering reduces electrical load on the controller so all four slots stay stable at full capacity. ECC corrects single-bit errors in flight, but it cannot protect against multi-bit failures or controller faults. The 288-pin RDIMM form factor fits only DDR5 RDIMM slots, not UDIMM or SODIMM sockets.

2Rx4 96GB module density

Each 96GB module uses a 2Rx4 organisation, which is the specific density the board's memory population rules expect for 384GB operation. Using modules with a different rank structure or capacity per DIMM will prevent the system from recognising the full 384GB or from booting at all. Verify the motherboard manual for approved DIMM population order before installation.
