Short answer: The Supermicro X11DDW-NT supports dual LGA-3647 Socket P processors from Intel’s Xeon Scalable families, but the available Supermicro specifications do not confirm the exact Xeon Platinum 8175M SKU. Treat it as a possible platform match, not a guaranteed, manufacturer-validated combination, until you check the board’s current CPU support list and the processor’s exact OEM details.
What is confirmed about compatibility?
Supermicro specifies two LGA-3647 Socket P sockets and support for Intel Xeon Scalable processors on the X11DDW-NT. It also lists CPU TDP support up to 205 W. Those statements establish family-level platform support; they do not establish that the 8175M itself has been validated for this board. See Supermicro’s X11DDW-NT specifications and check its current CPU support information for the exact model before buying or installing.
The 205 W figure is the motherboard’s stated CPU TDP support ceiling, not the 8175M’s TDP. The available evidence does not establish the 8175M’s TDP, so do not use the board ceiling as a substitute for the processor’s specification. Confirm the exact part’s power requirements and ensure the board, chassis, power delivery, and cooling solution are suitable.
Which BIOS does the 8175M need?
Supermicro states that BIOS version 3.2 or later is required for second-generation Xeon Scalable processors codenamed Cascade Lake-R. That is a generation-specific requirement; Supermicro’s published note does not say that BIOS 3.2 is required for the first-generation 8175M.

The available information does not confirm a specific BIOS version for the 8175M. Check the board’s current CPU support list or ask Supermicro to confirm support for the exact processor identification before proceeding. Do not infer 8175M support from the Cascade Lake-R note.
What to verify before building
- Confirm the exact CPU SKU. Ask the seller for clear photos of the processor markings and its full identification. Match those details against the board’s current CPU support information or obtain confirmation from Supermicro.
- Check the board BIOS. Record the installed BIOS version and confirm whether a specific version is required for this exact CPU. The published 3.2-or-later note applies to second-generation Cascade Lake-R support, not automatically to the 8175M.
- Validate power and cooling. Confirm the processor’s own TDP and requirements from a reliable SKU-specific source, then check that the board and your server chassis and cooler can handle them. The board’s 205 W ceiling alone does not establish the processor’s power needs or cooler fit.
- Plan memory around the installed CPU and DIMMs. Check supported DIMM types, slot population, capacity, and operating speed for the final configuration; the board’s maximum listed memory rate is not guaranteed in every build.
- Protect the purchase. Verify the seller’s identity, processor condition, return terms, and compatibility claims before paying. Intel Community material describes the 8175M as not listed in Intel ARK and not sold as a boxed processor, so treat it as an OEM-oriented part rather than assuming standard retail packaging. That material does not establish current availability or pricing: Intel Community discussion, dated 2021-01-11.
X11DDW-NT specifications that shape the build
| Area | Supermicro-listed specification | What to account for |
|---|---|---|
| CPU platform | Two LGA-3647 Socket P sockets; Xeon Scalable family support; CPU TDP support up to 205 W | Family support does not confirm the 8175M SKU. The 205 W value is the board ceiling, not the 8175M’s TDP. |
| Memory | 12 ECC DDR4 RDIMM/LRDIMM slots; up to 3 TB; listed rates of 2133, 2400, 2666, and 2933 MT/s | Actual speed and capacity depend on the processor and DIMM configuration. Up to 2 TB Optane DC Persistent Memory in memory mode is listed for Cascade Lake only. |
| Storage | Intel C622 controller with 14 SATA 6 Gbps ports; four internal PCIe 3.0 x4 NVMe ports; one M.2 PCIe 3.0 x4 M-Key interface supporting 2242, 2260, 2280, and 22110 formats | Confirm that the intended drives and chassis connections suit the system layout. |
| Networking and expansion | Two 10GBase-T ports; PCIe 3.0 x32 left riser, x16 right riser, and x16 AOM slot | Riser and add-on-card fit depends on the chassis and system configuration. |
These are Supermicro product specifications; the board is identified as MBD-X11DDW-NT. Supermicro also lists SYS-1029P-WTRT and SYS-6029P-WTRT among optimized systems. Specifications and platform details are on the official product page.

Bottom line on using an 8175M
The X11DDW-NT’s dual LGA-3647 sockets and Xeon Scalable family support make it a plausible platform for the 8175M, but the exact SKU is not confirmed by the cited board specifications. Before committing, get SKU-specific support confirmation, verify BIOS and cooling requirements, and make the seller’s return terms part of your plan.
