8GB DDR3 SODIMM Kit

This 8 GB kit contains two 4 GB DDR3 SODIMM modules rated at 1066 MHz (PC3-8500) with CL7 timing. Each stick uses a 204-pin layout, runs at 1.5 V and is unbuffered, non-ECC and dual-rank 2Rx8. It is built for notebooks or small-form-factor systems that accept DDR3 SO-DIMM memory.

Suitable for DDR3 upgrades only

The kit suits owners of laptops or compact PCs that have two free DDR3 SODIMM slots and a memory controller able to run at 1066 MHz. It will not work in systems that need a different pin count, a different voltage or registered and ECC modules. Buyers whose hardware requires a newer DDR generation or a higher speed grade should look elsewhere.

1066 MHz DDR3 speed grade

The single specification that decides fit is the 1066 MHz DDR3 rating (PC3-8500). The memory controller must support this exact speed; otherwise the modules will either not post or will fall back to a lower frequency. Confirm the platform’s maximum DDR3 frequency before purchase.

Questions about this item

Does the 2x4GB kit include both SODIMM modules or do I need to buy a second stick separately?

The kit contains two 4 GB DDR3 SODIMM modules, giving 8 GB total; nothing else is required to populate a pair of slots.

Should I choose the 1066 MHz CL7 version or a faster DDR3 module for my laptop?

Select the 1066 MHz CL7 kit only if your system specifies PC3-8500 or DDR3-1066; faster DDR3 will down-clock to this speed.

What does the PC3-8500 rating mean once the memory is installed?

It indicates a maximum transfer rate of 8 500 MB/s at 1066 MHz with CL7 timing, which the memory controller will use if supported.
