4GB DDR3L 1600 SODIMM Module

This OWC memory module provides 4GB of DDR3L capacity at 1600 MT/s with CL11 latency. It uses a 204-pin SODIMM form factor and operates at 1.35V. The module is unbuffered, non-ECC and organised as 2Rx8.

Compatibility With Lenovo B41-30 B51-30

This upgrade is validated for the Lenovo B41-30 and B51-30 notebooks. It meets JEDEC standards and is RoHS compliant for a warranty-safe installation. Systems requiring ECC, registered DIMMs or a different voltage should use a different module.

204-Pin DDR3L 1600 Specification

The 204-pin DDR3L 1600 interface determines whether this module fits and functions in the target laptop. Matching this exact specification is the single factor that decides compatibility.

Questions about this item

Will this DDR3L 1600 CL11 1.35V SODIMM work in a Lenovo B41-30 that already has a factory 4GB module installed?

Yes, this 4GB 2Rx8 204-pin DDR3L 1600 PC3L-12800 CL11 1.35V Non-ECC SODIMM is listed as compatible with the Lenovo B41-30 and B51-30, so it can be added alongside the original memory.

How can I verify the module is running at DDR3L 1600 CL11 1.35V after I install it?

Check the memory speed, CAS latency and voltage in the BIOS or with a system-information tool such as CPU-Z; they should show 1600 MT/s, CL11 and 1.35 V for this part.

Does the 1S6T32R804GB module ship alone or with any extra parts such as a screwdriver or thermal pad?

The upgrade consists of a single 4GB DDR3L SODIMM; no tools, heat spreader or additional components are included.
