Compatible Hynix HMCG66AEBSA095N Replacement

This new A-Tech module is an 8GB DDR5 4800MHz SO-DIMM built to replace the Hynix HMCG66AEBSA095N. It uses a 262-pin layout, runs at 1.10V, and carries a CAS latency of 40. Major-brand DRAM ICs provide dependable performance for laptop and all-in-one upgrades.

Suits Hynix part replacement; not for ECC systems

This module suits owners of laptops or all-in-ones that require the exact Hynix HMCG66AEBSA095N specification. It is not for systems that need ECC or registered memory, nor for desktops using standard DIMM slots. Buyers who want more than 8GB per slot should look at higher-capacity DDR5 SO-DIMMs.

Key spec: 262-pin DDR5 SO-DIMM at 4800MHz

The single specification that decides fit is the 262-pin DDR5 SO-DIMM running at 4800MHz (PC5-38400) with 1Rx16 organisation. Verify that your laptop manual lists this exact speed, pin count, and voltage before ordering.

Questions about this item

Does the 262-pin DDR5 SODIMM fit my laptop's memory slot?

The module uses the standard 262-pin DDR5 SO-DIMM form factor. Check your laptop manual to confirm it accepts DDR5 SO-DIMM memory before purchase.

What is the correct way to seat the module so it posts on first boot?

Align the notch on the module with the key in the slot, insert evenly until the gold contacts are fully hidden, then press down until the side retention clips snap into the notches on both sides.

Will the 1Rx16 rank configuration ever need a firmware update or replacement?

The 1Rx16 DRAM organisation is fixed on the module and does not require firmware updates. The memory itself has no moving parts and is rated for continuous operation at 1.10 V.
