DELL Precision 7730 Motherboard H127X Xeon E-2176M 2.7GHz 6-Core accessory

SKU CH-YJHG-AMK17

A Precision 7730 motherboard with Xeon E-2176M 2.7 GHz 6-core processor, CM246 chipset, four DDR4 SODIMM slots up to 64 GB and multiple M.2 2280 drive bays

  • Intel Xeon E-2176M 6-core processor delivers workstation performance
  • 7 GHz base clock with 4.4 GHz turbo boost for demanding tasks
  • Supports up to 64 GB DDR4 ECC memory across four SODIMM slots
  • Intel CM246 chipset with vPro for remote manageability and security
  • Four M.2 2280 slots accept SATA or NVMe storage drives

Replacement Motherboard for Precision 7730

This board is a direct replacement for the Dell Precision 7730 mobile workstation. It integrates an Intel Xeon E-2176M processor with six cores and twelve threads running at a 2.7 GHz base frequency. The CM246 chipset provides vPro manageability for IT departments. It suits technicians restoring a failed system or upgrading from a lower-tier CPU.

Build Integration and Expansion

The board fits the existing Precision 7730 chassis and connects to the MXM slot for dedicated graphics. Four SODIMM slots accept DDR4 ECC or non-ECC modules at 2400, 2666 or 2933 MHz up to 64 GB total. Up to four M.2 2280 bays support SATA or PCIe Gen3 x4 NVMe drives with SED encryption. Memory configurations range from 8 GB to 64 GB in validated layouts.

Thermals and Power Profile

The Xeon E-2176M carries a 45 W TDP, cooled by the laptop's original heatsink and fan assembly. Integrated Intel UHD Graphics P630 handles light workloads without engaging the discrete GPU. Under sustained multi-core turbo up to 4.4 GHz the cooling solution manages heat within the chassis limits. Power draw scales with load and selected graphics configuration.

Questions about this item

Will the 45 W TDP limit the Xeon E-2176M from holding its 4.4 GHz turbo during long renders?

The 45 W TDP is the sustained power ceiling; the processor will throttle from its 4.4 GHz max turbo to stay within that envelope under continuous full-core load.

How much fan noise and case heat should I expect when the board runs at 45 W all day?

A 45 W TDP in a 17-inch workstation chassis typically produces moderate fan noise and noticeable keyboard-deck warmth during extended heavy workloads.

Which DDR4 SODIMM kits must I already own to populate the four slots up to 64 GB?

You need DDR4 ECC or non-ECC SODIMMs rated for 2400, 2666 or 2933 MHz, in 8 GB, 16 GB or 32 GB modules, to reach the 64 GB maximum across the four slots.
