This 4GB DDR3 1066MHz SODIMM module is built for the Lenovo 3000 G550 series. It runs at PC3 8500 speed with CL7 timing and 1.5V voltage. The unbuffered, non‑ECC stick uses a 204‑pin layout and 2Rx8 rank. It targets owners of compatible Lenovo notebooks who need a direct memory upgrade.

Check your Lenovo 3000 G550 model

Verify that your exact model appears in the 2958‑Xxx, 59‑031837 or 59‑034045 series lists. The system uses two SODIMM slots and supports a maximum of 4GB with a 32‑bit OS or 8GB with a 64‑bit OS. This kit provides a single 4GB stick, so confirm you have a free slot and the correct operating‑system architecture.

Sustained load runs at rated DDR3 1066MHz

Under continuous workloads the module maintains its specified 1066MHz frequency and 7‑7‑7 timings at 1.5V. No heat spreader is fitted, so the notebook’s internal airflow handles thermal management. The major‑brand chipset and unbuffered design deliver stable throughput for everyday multitasking and background tasks.

Is the single 4 GB module the only capacity option for this Lenovo 3000 G550 upgrade?

This listing is a 1-piece 4 GB kit; the laptop accepts two SODIMMs for a maximum of 8 GB with a 64-bit OS.

Will the 1066 MHz CL7 rating run at that speed once installed in the G550?

The module is rated DDR3-1066 (PC3-8500) CL7 and will operate at that frequency and latency when the system supports it.
