Lenovo G770 4 GB DDR3 SODIMM

This module adds four gigabytes of DDR3 memory to a Lenovo G770 notebook. It runs at 1333 MT/s with CL9 timing on a 1.5 V unbuffered 204-pin package. The stick is built to JEDEC and RoHS standards and carries a limited lifetime warranty from OWC.

Suits G770 owners wanting a single-slot boost

Buyers who need more than one module or a higher total capacity should look elsewhere. Systems that require ECC or registered DIMMs cannot use this part. Laptops other than the G770 are not guaranteed to work with this specific module.

4 GB single-module capacity

The 4 GB density on a single 2Rx8 SODIMM is the figure that decides fit. If the G770 has two slots and one is free, this module fills it; if both slots are occupied or the board demands a different rank layout, the upgrade will not work.

Questions about this item

Will this 204-pin SODIMM fit the memory slots in my Lenovo G770?

Yes, the module is built to the exact 204-pin DDR3 SODIMM form factor used by the G770, so it seats directly in the laptop’s memory socket.

Can I keep the original memory installed and add this 4 GB stick alongside it?

The G770 has two SODIMM slots; adding this 4 GB module to the existing stick gives 8 GB total provided the original is also DDR3 1333 non-ECC.

How can I verify the new module is running at PC3-10600 speed after installation?

Open Task Manager’s Performance tab or a tool such as CPU-Z; the memory section will report 4 GB detected and a DRAM frequency of 1333 MHz.
