DELL Latitude 3390 2-in-1 Motherboard i3-7020U 2.3GHz J8NR3

SKU CH-4DEF-02TKV

Replacement system board for the Latitude 3390 2-in-1 with an on-board Intel Core i3-7020U dual-core processor at 2.3 GHz

  • Genuine Dell OEM part ensures exact fit for Latitude 3390 2-in-1
  • On-board Intel Core i3-7020U at 2.3 GHz delivers dual-core performance
  • Direct replacement motherboard restores full system function
  • Dell part number J8NR3 confirms correct component match
  • Includes factory-installed processor eliminates separate CPU installation

Genuine Dell Latitude 3390 2-in-1 System Board

This genuine Dell OEM motherboard serves as a direct replacement for the Latitude 3390 2-in-1 laptop. It arrives with the Intel Core i3-7020U dual-core processor permanently soldered at 2.3GHz. The board carries Dell part number J8NR3 and matches the original factory specification.

Fits Latitude 3390 2-in-1 Chassis Precisely

The system board is engineered to the exact mechanical and electrical layout of the Latitude 3390 2-in-1, so existing mounting points, connector positions and cooling interfaces align without modification. Reusing the original heatsink, display cable and daughter-board connections frees the builder from sourcing model-specific ancillaries.

Sustained Load Behaviour With Soldered i3-7020U

Because the CPU is soldered directly to the board, thermal transfer relies entirely on the laptop’s factory cooling solution rather than a socketed upgrade path. Under prolonged workloads the dual-core 2.3GHz processor will throttle according to the chassis thermal limits, delivering consistent baseline throughput instead of short burst peaks.

أسئلة حول هذا المنتج

What thermal limit does the on-board i3-7020U hit first under sustained load?

The dual-core i3-7020U at 2.3 GHz will reach its TDP ceiling before the board VRM or memory limits become the bottleneck.

How loud and hot does the Latitude 3390 2-in-1 run with this board during all-day use?

The thin 2-in-1 chassis relies on a single small fan; expect audible spin-up and surface warmth near the hinge within an hour of continuous CPU load.

Which existing Latitude 3390 2-in-1 parts must I reuse for this J8NR3 motherboard to work?

You must reuse the original display assembly, keyboard, battery, SSD, Wi-Fi card and bottom cover — the board only supplies the CPU and chipset.
