Upgrade Kit for DDR3 Notebooks

This 8 GB kit contains two 4 GB SO-DIMMs built to the DDR3 1600 standard. It is designed for laptops that accept 204-pin unbuffered memory running at 1.5 V. The dual-channel layout helps the system handle several programs at once.

Suits Owners of Compatible DDR3 Laptops

Buyers whose notebooks have two free slots and support PC3-12800 modules will see a straightforward capacity increase. Systems that require ECC, registered DIMMs, a different voltage or a newer memory generation cannot use this kit.

Deciding Specification — DDR3 1600 CL11 1.5 V

The modules run at 1600 MHz with CAS latency 11 at the standard 1.5 V. If the laptop’s memory controller expects this exact speed, timing and voltage, the kit will work; otherwise the system may not boot or will fall back to a lower speed.

Questions about this item

Does the kit include both 4 GB modules or do I need to buy a second stick?

The kit contains two 4 GB modules for a total of 8 GB, so no extra sticks are required.

Why is this kit labelled 1RX8 and not 2RX8?

1RX8 means each 4 GB module uses a single rank of x8 chips, which is the standard layout for DDR3 SODIMM upgrades in most notebooks.

What does the PC3-12800 rating tell me about actual speed?

PC3-12800 corresponds to DDR3-1600, so the modules run at 1600 MHz with CL11 latency at 1.5 V.
