4GB DDR3 1333 dual-channel kit

This kit supplies 4 GB of DDR3 laptop memory as two matched 2 GB SO-DIMM modules. Rated at 1333 MHz with CL9 latency and 1.5 V operation, it follows JEDEC PC3-10600 specifications. The 204-pin unbuffered non-ECC design targets laptops, all-in-one desktops and compatible NAS units.

Fits DDR3 SO-DIMM slots only

Suitable for owners upgrading a DDR3-era notebook, compact desktop or NAS that accepts 204-pin modules at 1.5 V. Not intended for systems that require registered or ECC memory, nor for platforms using a different DDR generation or a different pin count.

Dual-channel 2×2 GB configuration

The pair of identical 2 GB sticks enables dual-channel bandwidth on boards with two slots. Builders needing a single larger module or a higher total capacity should select a different kit.

Questions about this item

Does my laptop need a 204-pin DDR3 slot to use this kit?

Yes — the modules are 204-pin DDR3 SO-DIMMs that fit standard laptop memory slots.

Can I keep my existing 1333 MHz DDR3 stick and add this pair?

The kit runs at 1333 MHz CL9 1.5 V; matching speed, voltage and timing lets it work in dual-channel alongside an identical module.

How do I confirm the kit is running at 1333 MHz after installation?

Check the memory speed in BIOS or a system tool such as CPU-Z — it should report 1333 MHz (PC3-10600) with CL9 timings.
