CMS 8GB DDR3 1600MHz SODIMM Kit

This 8GB kit contains two 4GB unbuffered DDR3 SO-DIMM modules rated at 1600MHz with CL11 timing. It operates at 1.5V and uses a 204-pin interface designed for compatible notebook systems. The modules are non-ECC and feature a 2Rx8 rank configuration with major brand chipsets.

For Dell Inspiron 15 M5040 Upgrades

This memory is guaranteed compatible with the Dell Inspiron 15 M5040 notebook which supports a maximum of 8GB across two sockets. Modules must be installed in pairs to enable dual-channel mode where supported. Builders needing higher capacity or a different memory generation should look at other options.

DDR3 1600MHz 204-Pin Specification

The decisive specification is the DDR3 1600MHz (PC3-12800) 204-pin SO-DIMM form factor. This generation and pin count are physically and electrically distinct from other memory types. Verify your system requires DDR3 SO-DIMM modules before purchasing.

Questions about this item

Will this 204-pin DDR3 kit work in my Dell Inspiron 15 M5040 without any other memory installed?

Yes, the 8 GB kit (2 x 4 GB) fills both sockets of the Inspiron 15 M5040 and runs at 1600 MHz with CL11 timing at 1.5 V.

Can I keep one existing 4 GB module and add just one stick from this kit?

The system requires modules to be installed in matched pairs for dual-channel mode, so both 4 GB sticks from this kit should be used together.

How can I verify the kit is running at the rated 1600 MHz after installation?

Check the memory speed in the BIOS or a system-information tool; it should report DDR3-12800 (1600 MHz) with 11-11-11 timings.
