8GB DDR4 3200 SODIMM for Hynix replacement

This A-Tech module delivers 8 GB of DDR4 3200 memory in a 260-pin SO-DIMM form factor. It runs at 1.20 V with CL22 latency and is unbuffered non-ECC. The stick is built as a direct replacement for Hynix HMAG68EXNSA051N in laptops, notebooks and all-in-one PCs.

Suits owners of the exact Hynix part needing

Buyers who need ECC error correction, registered buffering, a different voltage or a higher speed grade should look elsewhere. Systems limited to lower DDR4 speeds will still run the module but at the reduced rate, and desktops requiring 288-pin DIMMs cannot use this SO-DIMM.

Match the HMAG68EXNSA051N part number before

The single decisive specification is the manufacturer part number HMAG68EXNSA051N; only systems qualified for that exact module will guarantee compatibility. Verify the part number on your existing memory or in the service manual before purchasing.

Questions about this item

Will the CAS latency of CL22 need adjustment when this 8 GB DDR4 3200 SODIMM is installed?

The module runs at its rated CL22 timing by default; no manual latency changes are required for standard operation.

What thermal limit appears first during continuous heavy workloads on this unbuffered 1.2 V DDR4 3200 module?

Without a heat spreader, the DRAM chips reach their maximum junction temperature before any other component becomes a bottleneck.

How much power does the 1.20 V 8 GB DDR4 3200 SODIMM draw when the laptop runs all day?

At the standard 1.20 V DDR4 voltage the module typically consumes a few watts, adding minimal heat and no audible noise to the system.
