8GB DDR3 SODIMM kit for Lenovo Y550P

This 8GB kit contains two 4GB DDR3 1066MHz SODIMM modules built to PC3-8500 specification with CL7 timing. The unbuffered non-ECC sticks run at 1.5V and use a 204-pin layout designed for the Lenovo Ideapad Y550P 3241-Xxx notebook series. Computer Memory Solutions validates compatibility for the listed models.

Suits owners of a compatible Y550P needing maximum

The kit fills both memory sockets in the supported notebook and reaches the 8GB ceiling when a 64-bit operating system is installed. Buyers running a 32-bit OS will be limited to 4GB usable capacity and should consider that constraint before purchasing. The modules are not ECC or registered and will not serve server or workstation boards requiring those features.

Verify OS architecture

Confirm the notebook runs a 64-bit operating system to address the full 8GB and check that both SODIMM sockets are vacant or that existing modules can be removed. The system uses two slots and the kit occupies both. Ensure the platform accepts DDR3 1066MHz unbuffered non-ECC memory at 1.5V with 2Rx8 organisation.

Questions about this item

Does this kit need two free 204-pin SODIMM slots to install?

Yes, the kit contains two 4 GB DDR3-1066 modules and the Lenovo Ideapad Y550P 3241-xxx has two SODIMM sockets, so both slots must be free.

Will the 1.5 V DDR3-1066 modules run without changes if I keep the original memory?

The sticks operate at standard 1.5 V with CL7 timing; if the existing memory matches DDR3-1066 1.5 V they will run together at that speed.

How can I confirm the full 8 GB is recognised after fitting the pair?

Boot into a 64-bit operating system and check the installed memory in Task Manager or System Information — it should show 8 GB usable.
