Dell Inspiron 15 3565 memory upgrade

This 4 GB DDR4 SODIMM is built for the Dell Inspiron 15 3565. It adds a single 260-pin module to one of the two available slots. Buyers who need more than 16 GB total capacity cannot use this kit.

DDR4 2400 CL17 practical limits

The module runs at 2400 MHz with CL17 timing and 1.2 V unbuffered operation. It is non-ECC and uses a 2Rx8 organisation. Systems that require ECC or registered memory will not accept this stick.

Replaces slower or smaller DDR4 SODIMMs

Swapping an existing 2 GB or lower-speed DDR4 module for this 4 GB CL17 unit raises the ceiling toward the 12 GB or 16 GB maximum. The jump is worth it when the current configuration leaves a free slot or runs below 2400 MHz.

Questions about this item

Should I buy the 4 GB stick or aim for the 12 GB or 16 GB maximum this laptop supports?

The system accepts up to 12 GB or 16 GB across two slots. Adding this 4 GB module to an existing 4 GB stick reaches 8 GB; filling both slots with 8 GB modules hits the 16 GB ceiling.

What does the 2400 MHz rating actually deliver inside the Inspiron 15 3565?

The module runs at DDR4 2400 (PC4 19200) with CL17 timing at 1.2 V. If the laptop's memory controller tops out lower, the stick simply downclocks to match.

Does the 260-pin SO-DIMM interface limit speed or capacity in this machine?

The 260-pin DDR4 SO-DIMM form factor is the standard for this platform. It carries the 2400 MHz signal and supports the 12 GB or 16 GB maximum the board allows.
