4GB DDR3 1333 SODIMM for Lenovo IdeaPad

This 4GB DDR3 1333 CL9 1.5V SODIMM module is built for Lenovo IdeaPad V470 V570 Y470 Y560P Y570 Z360 and Z370 notebooks. It uses a 204-pin unbuffered non-ECC design rated at PC3-10600. The single-rank 2Rx8 layout matches the original factory specification. Buyers who need ECC error correction or registered buffering should look elsewhere.

JEDEC-standard DDR3 sustains rated speed under load

The module meets JEDEC PC3-10600 timings at 1333MHz with CL9 latency and 1.5V operation. Because it is validated to the same electrical and thermal envelope as the OEM part it maintains stable throughput during extended multitasking sessions. No heat spreader is fitted so airflow in the memory slot handles cooling directly.

Verify slot count and maximum capacity before

Confirm the target laptop has a free 204-pin SODIMM slot and that the chipset accepts a 4GB DDR3 1333 module. Some listed models ship with both slots populated so a single 4GB stick may not increase total memory if the limit is already reached. Check the service manual for the exact slot layout and supported density per slot.
