16GB DDR4 SODIMM for Lenovo IdeaPad

This 16GB DDR4 2400MHz SODIMM module upgrades compatible Lenovo IdeaPad 330S and 510 series laptops. It uses a 260-pin unbuffered non-ECC design running at 1.2V with CL17 timing. The single stick provides a straightforward capacity increase for supported systems. Computer Memory Solutions guarantees compatibility with the listed models.

Suits owners of specific Lenovo laptops

This module fits IdeaPad 330S Intel variants, 510-15ISK, 510S-14IKB, 510S-14ISK and 510S models needing a 16GB upgrade. Buyers whose laptop is not on this validated list should look elsewhere. Systems limited to lower maximum memory or different pin counts cannot use this part. The single-socket design also means no dual-channel benefit is possible.

260-pin DDR4 2400MHz CL17 specification

The decisive spec is the 260-pin DDR4 2400MHz CL17 1.2V unbuffered non-ECC SODIMM form factor. Your laptop must accept this exact speed, voltage, latency and pin layout to work. Verify the model number against the supported list before ordering. Mixed modules will run at the slowest installed speed.

Questions about this item

How do I confirm the 16GB DDR4 2400MHz module is running at CL17 1.20V after installation?

Enter the BIOS or use a tool like CPU-Z to verify the memory reports 2400MHz speed, CL17-17-17 timings and 1.20V voltage.

What comes in the package and do I need any extra parts for my Lenovo IdeaPad 330S?

The box contains one 260-pin SODIMM stick; no additional components are required for the upgrade.

Should I choose the 16GB stick or add a smaller module to reach 20GB or 24GB total?

The system has one socket, so only a single 16GB module can be installed; 20GB or 24GB configurations are not possible.
