Lenovo G770 DDR3 SODIMM Upgrade

This OWC module adds 2GB of DDR3 1333 memory to a Lenovo G770 laptop. It is a non-ECC unbuffered SODIMM built to JEDEC standards and tested for warranty-safe installation.

Replaces Slower or Smaller Factory Memory

The jump is worth it when the G770 currently runs on less than its maximum supported capacity or on slower DDR3 speeds. A single 2GB stick fills one slot and raises total system memory for smoother multitasking and larger file handling.

Verify Slot Count and Maximum Capacity

Check how many SODIMM slots the G770 provides and what total memory the chipset accepts before ordering. The module operates at 1.5V with CL9 latency, so the system must support that voltage and timing. No heat spreader is included, so ensure the chassis has adequate airflow around the memory bay.

Questions about this item

Will this 204-pin SODIMM fit the memory slot in a Lenovo G770?

Yes, the module is built to the 204-pin DDR3 SODIMM form factor that the G770 uses.

What is the correct orientation when inserting this 1.5 V DDR3 module into the G770?

Align the notch on the gold edge connector with the key in the slot, press firmly until the side clips snap shut.

Does this 1Rx8 CL9 stick require any firmware update or matching pair later?

No firmware is needed; it runs at 1333 MHz CL9 as a single rank, and can stay alone or be joined by another identical module.
