SK Hynix HMCG78MEBUA084N 16GB Review
SK hynix HMCG78MEBUA084N is a 16GB DDR5-4800 UDIMM, SK hynix's baseline-speed OEM tray part at this capacity.
16GB capacity and DDR5-4800 speed decode from the part number and are confirmed by the product image label. The MEB suffix marks the JEDEC-baseline 4800MT/s bin rather than the faster 5600 bin used on the AGB-suffix siblings elsewhere in this catalog. No published CAS latency or overclock profile.
What we can and can't verify
HMCG78 is SK hynix's 288-pin desktop UDIMM DDR5 family; MEB maps to 4800MT/s. No confirmed CAS latency, sub-timings, or XMP/EXPO support for this OEM part.
Compatibility
Standard 288-pin desktop DIMM; runs at JEDEC DDR5-4800 on any current Intel or AMD board.
Comparison to Alternatives
Against SK hynix's own HMCG78AGBUA084N (same 16GB UDIMM but DDR5-5600), that part is the faster option; this 4800MT/s part is typically the cheaper baseline pick.
