Dell Inspiron 3520 configuration

This Dell Inspiron 3520 laptop pairs an 11th Gen Intel Core i5-1135G7 processor with 64GB DDR4 memory. It runs Windows 11 Pro on a 15.6 inch 120Hz Full HD display. Dual storage combines a 256GB NVMe SSD with a 1TB hard drive. The system ships new with a three-cell 41 WHr battery.

Suits multitaskers needing memory headroom

The 64GB DDR4 capacity supports heavy browser tabs, virtual machines and large datasets without paging. Integrated Iris Xe graphics handle office apps and media playback but cannot drive modern 3D titles or GPU compute workloads. Buyers who want discrete graphics or a touchscreen should look at something else.

Sustained load behaviour

The 65W power adapter feeds a 15W-class quad-core CPU that can reach 4.2 GHz in short bursts. Under continuous load the chip throttles to stay within thermal limits, so clock speeds settle lower than the peak figure. The 120Hz panel remains responsive while the fan manages heat from the single heat pipe.

Questions about this item

What existing laptop must I open to install the 64 GB DDR4 memory and the 256 GB 2230 PCIe NVMe SSD?

This Inspiron 3520 already ships with 64 GB DDR4 and the 256 GB 2230 PCIe NVMe SSD installed, so no extra parts or donor laptop are required.

Will my Bluetooth 5.0 headset and 802.11ac router work with the built-in wireless card?

Yes — the laptop includes Bluetooth 5.0 and 802.11ac Wi-Fi, so your current headset and router will connect without adapters.

How can I confirm the 15.6-inch 120 Hz 1920 x 1080 panel is running at its full refresh rate?

Open Windows Settings → System → Display → Advanced display and verify the refresh rate dropdown shows 120 Hz for the built-in screen.
