Direct replacement DDR5 SODIMM
This 16 GB DDR5 module matches the Hynix HMCG78MEBSA092N and HMCG78MEBSA095N part numbers exactly. It is built for laptops, all-in-one PCs and NAS units that require a 262-pin SO-DIMM running at 1.1 V. The unbuffered, non-ECC design suits standard consumer platforms.
DDR5 4800 speed ceiling
The JEDEC-standard PC5-38400 4800 MT/s rating is the maximum data rate this stick can deliver; the memory controller will not exceed it. CAS latency is fixed at CL40, so tighter timings are not available. Systems that only support lower DDR5 speeds will downclock the module automatically.
16 GB single-rank capacity
One 1Rx8 rank provides 16 GB in a single slot, which is the largest density this part number offers. Buyers who need more total memory must populate additional slots with identical modules. Systems limited to one SO-DIMM socket cannot exceed this capacity.
