What this module is

The SK hynix HMCG78MEBSA is a 16GB DDR5 SO-DIMM running at 4800MHz with CL40 latency. It uses a 262-pin layout and operates at 1.1V without ECC or buffering. This stick targets owners of DDR5-ready laptops, notebooks or all-in-one PCs who want a straightforward capacity upgrade.

Who this suits and who it does not

Builders with DDR5-compatible platforms that accept unbuffered non-ECC memory will find it a direct fit. Buyers whose systems require registered or error-correcting modules should look elsewhere. Laptops limited to lower-speed DDR5 standards may not reach the rated frequency. Anyone needing more than a single 16GB rank must add another module.

The deciding specification

The 262-pin DDR5 SO-DIMM form factor is the single detail that determines compatibility. Only devices designed for this exact pin count and DDR5 signalling can install the module. Verify the motherboard manual before purchase.

Questions about this item

Should I choose the HMCG78MEBSA, HMCG78MEBSA095N or HMCG78MEBSA092N version?

All three part numbers refer to the same 16GB 1Rx8 DDR5 4800MHz CL40 unbuffered SODIMM; pick whichever is in stock.

What does the 4800MHz rating mean once the module is installed in my laptop?

The memory will operate at 4800 MT/s at CL40 latency, providing standard DDR5 bandwidth for your system.

What does the PC5-38400 designation cap in practice?

PC5-38400 confirms the 4800 MT/s data rate and 1.1V voltage for DDR5 SO-DIMM platforms.
