Lenovo B575 1450 SODIMM kit

This kit provides 8 GB of DDR3 memory in two 4 GB modules built for the Lenovo B575 1450-Xxx series notebook. Each stick uses a 204-pin SO-DIMM form factor and runs at 1333 MHz with CL7 timing at 1.5 V. The unbuffered, non-ECC design matches the original specification for straightforward installation.

Upgrade from 4 GB or mismatched pairs

Replacing a single 4 GB module or a mixed-capacity pair with this matched 2×4 GB kit enables dual-channel operation and eliminates capacity imbalance. The jump is worth it when the system currently shows sluggish multitasking or frequent paging to disk. Buyers who need more than 8 GB total capacity cannot use this kit.

Fits the factory slot layout

The two modules occupy the two SO-DIMM slots provided in the compatible notebook, leaving no empty slots for further expansion. No heat spreader is fitted, so the modules sit flush under the standard access cover. The 1.5 V operating voltage matches the platform requirement without additional configuration.
