4GB DDR3 1333MHz SODIMM for laptop upgrades

This A-Tech module provides 4GB of DDR3 memory at 1333MHz with CL9 latency and 1.5V operation. It uses a 204-pin SO-DIMM form factor and unbuffered non-ECC chips. The stick is designed as a direct replacement for several Kingston part numbers including KVR13S9S8/4 and KFJ-FBS/4G. All modules are tested for reliability before shipping.

Suits laptops and all-in-one PCs accepting DDR3

The single 4GB module works in notebooks that support PC3-10600 unbuffered memory at standard voltage. Buyers needing ECC or registered memory should look elsewhere. Systems limited to lower voltage modules cannot use this 1.5V part. Verify your device's maximum supported capacity and slot count before ordering.

1333MHz DDR3 speed and CL9 timing

The rated DDR3 1333 (PC3-10600) speed with CL9 latency determines whether this module matches your system's memory controller requirements. Matching both the frequency and CAS latency avoids downclocking or instability. Check your laptop's specifications for supported memory speeds and timings.

Questions about this item

Will this 204-pin DDR3 1333 MHz SODIMM run with my existing 10600 CL9 modules?

Yes, it matches the same 1333 MHz speed, CL9 latency and 1.5 V voltage, so it will operate alongside identical-spec modules without timing conflicts.

How can I confirm the module is running at 1333 MHz after installation?

Open Task Manager or CPU-Z; the memory tab should show 1333 MHz (PC3-10600) and CL9 timings at 1.5 V.

Does the package include only the 4 GB SODIMM or any extra parts?

The box contains the single 4 GB 204-pin DDR3 SODIMM; no tools, adapters or additional components are supplied.
