Dell Precision 7740 Motherboard VG304

This genuine OEM motherboard is built for the Dell Precision 7740 mobile workstation. It ships with an Intel Core i9-9980H processor installed, running at 2.4 GHz base frequency. The board uses the Intel CM246 chipset and targets IT technicians and DIY repairers who need a direct factory replacement.

Quad-channel DDR4 and dual M.2 slots

Four DDR4 memory slots support up to 128 GB capacity with ECC capability for error-free data processing. Two M.2 PCIe 3.0 x4 slots enable NVMe SSD configurations including RAID 0 or RAID 1. An MXM 3.1 graphics slot accepts professional NVIDIA Quadro or AMD Radeon Pro modules for CAD and rendering workloads.

Integrated Thunderbolt 3 and display outputs

The board provides native Thunderbolt 3 connectivity through USB-C alongside HDMI 2.0 and DisplayPort 1.4 support for multi-monitor setups. Designed to match the Precision 7740 chassis, power system and peripheral layout exactly, it ensures mechanical alignment without modification. Buyers needing a different CPU socket or chipset platform cannot use this part.

Questions about this item

Will the quad DDR4 slots with ECC support need individual module replacement if a memory error occurs?

Yes, each DDR4 ECC module can be replaced independently in the four slots without swapping the entire motherboard.

Does the Intel CM246 chipset throttle the i9-9980H at its 2.4 GHz base clock during continuous rendering workloads?

The CM246 chipset manages power delivery for sustained 2.4 GHz operation; thermal limits depend on the Precision 7740 cooling assembly attached to this board.

How loud does the MXM 3.1 graphics slot area get when a Quadro GPU runs at full load all day?

Fan noise is determined by the Precision 7740 chassis cooling solution, not the motherboard itself, which has no integrated fans.
