If you are building a home server for running serious workloads on-premises, we recommend a pair of Xeons and Socket FCLGA3647 Motherboards to run them. Also known as Socket P, these motherboards use high-performance interconnects to support Dual-Socket Xeon CPUs and is currently the best alternative to AMD’s EPYC CPUs. To find out more, read along.
The Purley Platform from Intel has introduced a new socket in the form of LGA 3647. The socket will be supported on the Skylake processors from Intel. Specially designed for use with the server backed motherboard, it is quite large enough compared to the LGA 2011-3 socket. Now, which motherboards do support the LGA 3647 socket, we will check out the options we may have at our disposal.
The LGA 3647 Socket – An Overview
Well, before we can move on to explore the motherboard that features the LGA 3647, we will first make an attempt at understanding the concept and functionality of the socket.
The socket LGA 3647 does not support latches and thus opts for a different cooling mechanism. The coolers are secured to the top of the socket utilizing screws. These are generally used in the form of passive heatsinks that are cooled by the ambient airflow inside the server rooms.
The standard processors supported by the LGA 3647 include Xeon Phi x200 (“Knights Landing”), Xeon Phi 72×5 (“Knights Mill”), and Skylake-EX and -SP (Xeon “Purley”) microprocessors. A few features that it supports include a 6-channel memory controller, non-volatile 3D XPoint memory DIMMs, Intel UltraPath Interconnect (UPI), as a replacement for QPI and 100G Omni-Path interconnect.
Do note that the LGA 3647 supported motherboards are explicitly designed for the management of servers and workstations. That would indeed make the availability of your options quite limited.
Socket FCLGA3647 Motherboards
Today, we are talking about Intel’s FCLGA 3647 socket. Since most of you might already know that it is a socket specially designed for Intel Xeon family processors, these microprocessors are specially optimized for powering stackable server systems. However, to get most of these CPUs, specialized motherboards are used. Today, we are discussing some of the best motherboards offering Intel FCLGA Socket. Currently, the following models are available online on various marketplaces:
- Supermicro MBD X11DPH TO –

The following are detailed specifications of these motherboards. We hope these detailed specs and technical details are enough for you to understand the major differences between these products and their performance levels. Still, feel free to use the comment box if there is any doubt. So without any more delay, here we begin with the list of best socket FC-lga3647 motherboards:

This is also an E-ATX form factor motherboard. Also, some aspects of the layout are different than a standard ATX system, and you might need to make some modifications to complete the assembly. There are plenty of customization options in the BIOS, and we highly recommend to update it to the latest. Also, we recommend using low-profile DDR4 memory, since there are space limitations for DIMMs with taller heatsinks.
