4GB DDR3L 1333MHz SODIMM

This 4GB DDR3L module runs at 1333MHz with CL9 latency and operates at 1.35V. It uses the 204-pin SO-DIMM form factor for laptop and all-in-one systems. The unbuffered, non-ECC design suits standard consumer notebooks. A-Tech tests every module before shipping.

Suitable for DDR3L laptop upgrades

Owners of compatible laptops or all-in-one PCs needing a 4GB DDR3L 1333MHz replacement will find this module matches the Hynix HMT451S6AFR8A-H9 series specifications. Systems requiring ECC, registered memory, higher capacities, or different DDR generations cannot use this part. Buyers wanting more storage should look at storage drives instead.

1.35V DDR3L low-voltage operation

The 1.35V rating identifies this as DDR3L, which is the single specification deciding compatibility with systems that require low-voltage DDR3 memory. Standard 1.5V DDR3 modules may not work in these platforms. Verify your system supports DDR3L 1333MHz PC3L-10600 before purchase.

Questions about this item

Will this DDR3L 1333MHz CL9 1.35V module run cool and quiet in a laptop chassis under continuous load?

DDR3L 1.35V modules draw less power than standard 1.5V DDR3, so heat output is lower and the cooling fan spins less often during all-day workloads.

Does my laptop need a 204-pin DDR3 SO-DIMM slot to accept this upgrade?

Yes — this is a 204-pin DDR3 SO-DIMM; the socket must match that form factor and support DDR3 or DDR3L signalling.

Is this RAM a direct replacement for Hynix HMT451S6AFR8A-H9 and the other listed part numbers?

It is built as a compatible equivalent for those four Hynix part numbers, matching 4GB, 1333MHz, CL9, 1.35V, 1Rx8 unbuffered specifications.
