Replacement motherboard for Precision 7520 laptops with soldered Xeon E3-1545M v5 processor and four DDR4 slots supporting 64 GB

  • Intel Xeon E3-1545M v5 processor delivers workstation performance
  • 4 cores and 8 threads handle multi-threaded workloads
  • Base 2.9 GHz with turbo up to 3.80 GHz for demanding tasks
  • Supports up to 64 GB DDR4 memory across four slots
  • Intel CM236 chipset with integrated HD Graphics P530

Precision 7520 workstation board

This Dell Precision 7520 motherboard carries an Intel Xeon E3-1545M v5 processor soldered in a BGA1440 socket. The quad-core CPU runs at a 2.9 GHz base clock and reaches 3.80 GHz turbo with 8 MB L3 cache. It targets professionals replacing a failed board in a compatible 15-inch Precision chassis.

CM236 chipset and DDR4 layout

The Intel CM236 chipset provides four SODIMM slots supporting DDR4 memory up to 2400 MHz and a 64 GB maximum capacity. Integrated Intel HD Graphics P530 handles display output without a discrete GPU. The 45 W TDP matches the original thermal solution designed for the Precision 7520 enclosure.

Direct replacement for Precision 15 7520

The board includes the processor and chipset pre-assembled, so no separate CPU installation or firmware update is required. Buyers who need a different processor generation, a discrete graphics option, or a chassis other than the Precision 15 7520 cannot use this part.
