Compatible Dell Inspiron 3647 Memory

This 4 GB DDR3 module is built specifically for the Dell Inspiron 3647 desktop. It installs directly into a 240-pin DIMM slot and runs at 1600 MHz with CL11 timings. The stick is unbuffered, non-ECC and operates at the standard 1.5 V.

Suited for single-stick upgrades

The kit suits owners who want to add one 4 GB stick to a free slot or replace a failed module in an Inspiron 3647. It is not for systems that require ECC or registered memory. Buyers needing higher frequencies or lower latencies should look at something else.

4 GB capacity with 16 GB ceiling

The module provides 4 GB of usable memory and the board supports a maximum of 16 GB across its two slots. Everyday office work and light multitasking run comfortably within this limit. Heavier workloads or modern gaming will run out of headroom quickly.

Questions about this item

Does my Dell Inspiron 3647 need a free 240-pin DIMM slot for this 4GB module?

Yes, the desktop has two 240-pin DDR3 slots and this stick occupies one of them.

Will this 1600MHz CL11 stick run correctly with any existing 1333MHz memory I keep installed?

The system will clock both modules to the lowest common speed, so the 1600MHz module will operate at 1333MHz alongside the older stick.

How can I verify the module is recognised at 1600MHz with CL11 timings after installation?

Enter the BIOS or use a system-information utility; it should report 4GB DDR3 running at 1600MHz with 11-11-11 latency.
