CMS 4GB DDR3L SODIMM for Dell Latitude 3330

This 4GB DDR3L SODIMM module runs at 1600MHz with CL11 latency and 1.35V operation. It is built specifically for the Dell Latitude 3330 notebook using a 204-pin unbuffered non-ECC design. The single 1Rx8 rank stick provides a straightforward memory upgrade for that platform.

Sustained load behaviour with DDR3L 12800 speed

Operating at the standard DDR3-12800 data rate, the module maintains its 11-11-11 timing under continuous workloads typical of office applications and web browsing. The low 1.35V voltage helps limit thermal output during extended sessions. No heat spreader is fitted, so airflow within the chassis manages component temperature.

Check your Latitude 3330 configuration before

Verify the notebook has a free SODIMM slot, as the system supports a maximum of 8GB across two sockets. Ensure the existing memory is also DDR3L 1.35V to avoid voltage mismatch. This kit contains one 4GB stick and does not suit buyers who need an 8GB single module or a matched pair for dual-channel operation.

Questions about this item

Does this 1.35V DDR3L module draw less power than a standard 1.5V DDR3 stick during all-day use?

Yes, the 1.35V operating voltage reduces power draw compared with standard 1.5V DDR3, helping lower heat output during continuous operation.

Must the notebook already have a free 204-pin SODIMM slot to install this 4GB stick?

Yes, the Dell Latitude 3330 provides two 204-pin SODIMM sockets; one must be vacant for this module to fit.

Will this PC3L-12800 CL11 module run at the correct speed alongside the factory memory in a Latitude 3330?

The module is rated for DDR3L-1600 CL11 and the Latitude 3330 supports that speed, so it will operate at the specified timing when installed.
