4GB DDR3 1333MHz SODIMM for laptop upgrade

This 4GB DDR3 module runs at 1333MHz with CL9 latency and standard 1.5V operation. It uses the 204-pin SODIMM form factor and is built as an unbuffered, non-ECC stick. The module is designed as a direct replacement for Hynix HMT451S6 series parts in compatible laptops, notebooks and all-in-one systems.

Suits owners of DDR3 laptops needing a 4GB

Buyers whose systems require low-voltage operation at 1.35V should verify compatibility before purchase. Systems limited to lower DDR3 speeds or different pin layouts will not accept this module. It is not intended for desktop DIMM slots or servers requiring registered memory.

Speed and voltage decide fit

The module operates at DDR3 1333MHz (PC3-10600) with a 1.5V supply. Match these two specifications against your system's supported memory list to confirm the part will work.

Questions about this item

Does this 204-pin DDR3 SODIMM need anything other than a free DDR3 SO-DIMM slot to work?

It requires a laptop or all-in-one with an available DDR3 1333 MHz SO-DIMM socket and 1.5 V operation.

Will the 1333 MHz CL9 module down-clock to match slower DDR3 sticks I keep installed?

Yes, the module will run at the lowest common speed and latency of all installed DDR3 memory.

How can I confirm the new 4 GB stick is recognised at 1333 MHz after installation?

Check the memory speed and capacity in BIOS or with a tool such as CPU-Z or Task Manager.
