Precision 7730 motherboard for Xeon E-2176M

This genuine Dell system board (part H127X) fits the Precision 7730 mobile workstation. It is built around Intel's CM246 chipset and accepts the Xeon E-2176M processor. The board supports up to 128GB of DDR4 ECC memory across its slots. Sold as the bare board without CPU, RAM or storage.

Suits owners repairing a 7730 chassis.

This part matches the 2018 Precision 7730 enclosure, port layout and cooling mounts exactly. Buyers needing a board for a different Dell series or a non-Xeon CPU should look elsewhere. The MXM 3.0 graphics slot only accepts compatible Quadro modules such as the P3200, P4200 or P5200. It cannot take desktop graphics cards.

Deciding spec: Xeon E-2176M socket and CM246 chipset

The board is keyed for the Xeon E-2176M and the CM246 platform, so the processor choice is fixed. If your workflow requires that specific CPU and ECC memory support, this is the correct replacement. If you need a different processor family or a non-ECC configuration, this motherboard will not work.

Questions about this item

Does the H127X motherboard come with the Xeon E-2176M CPU, DDR4 RAM, or M.2 NVMe SSDs installed?

No. The listing states the motherboard is sold without the CPU, RAM, or storage. You must supply a compatible Xeon E-2176M processor, up to 128GB DDR4 ECC memory, and your own M.2 NVMe or SATA drives.

Which processor is this H127X board designed for, and can I use a different Intel chip?

This motherboard is engineered specifically for the Intel Xeon E-2176M (6-core/12-thread). The socket and CM246 chipset are matched to that processor; other CPUs are not supported.

What does the triple M.2 specification mean for my storage setup inside the Precision 7730?

The board provides three M.2 slots: two wired for NVMe SSDs and one for a Wi-Fi 6/Bluetooth 5 module. It also retains a SATA III connector for a 2.5-inch drive.
