Dell Inspiron 17R 5720 memory upgrade

This 8 GB kit contains two 4 GB DDR3 SODIMM modules built for the Dell Inspiron 17R 5720 notebook. The unbuffered, non-ECC sticks run at 1600 MHz with CL11 timing at 1.5 V. They fill both memory sockets to reach the system maximum of 8 GB.

Tool-free slot access under a bottom panel

Installation requires removing a single screw and lifting the memory cover. The 204-pin modules key into the slots in one direction; forcing them backwards is the common error. No BIOS update or jumper change is needed for the rated speed.

DDR3 1600 ceiling on a two-slot platform

The chipset caps memory at DDR3 1600, so faster modules will downclock to this speed. Only two SODIMM sockets exist, limiting total capacity to 8 GB and preventing future expansion beyond this kit.

Questions about this item

How can I confirm the CL11 1600MHz SODIMMs are running at the correct speed after installation?

Open Task Manager, select the Performance tab, then Memory, and verify the reported speed shows 1600 MHz and the form factor reads SODIMM.

What comes in the package and do I need any extra parts for my Dell Inspiron 17R 5720?

The kit includes two 4GB 204-pin DDR3 SODIMM modules; the notebook has two slots supporting a maximum of 8GB, so no additional memory is required.

Which capacity kit matches the 8GB maximum supported by the Inspiron 17R 5720?

The 8GB kit (2 x 4GB) exactly fills both sockets and reaches the notebook's 8GB limit, making it the correct choice for a full upgrade.
