Best Socket FCLGA3647 Motherboards (Socket P) For Intel Xeon Platinum 8176 C621

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 designed specifically 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 – Check on Amazon
• ASUS WS C621E SAGE – $605.95
• ASRock EPC621D8A – Out of stock
• SUPERMICRO X11DPI-N – $540.00

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 level. 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:

1. SUPERMICRO MBD-X11DPH-TO:

Check on Amazon Check on Newegg

The Supermicro X11DPH-T Dual LGA 3647 Sockets Motherboard comes under the category of Dual Intel Xeon Scalable Processor Motherboards. Offering a maximum TDP of 205 Watts, it comes with 16 DDR4 DIMM slots.

The motherboard supports up to 2TB of 3DS ECC RDIMM or 3DS ECC LRDIMM DDR4 memory across 6-channels. Some of the features that would make it an excellent option would be

• Support for Intel® C624 Chipset.
• It comes with 3x PCI-E 3.0 x16, & 4x PCI-E 3.0 x8 Slots
• The motherboard supports Dual LAN with 10GBase-T with Intel® X557.

This is a C624 Chipset based dual socket motherboard suitable for Intel’s Xeon line of processors. It means that, technically, you can use a pair of Xeon Platinum 8176 processors, which provides 28 cores & 56 threads each, with a total of 56 Cores & 112 Threads and 432GB of system memory.

These setups are ideally suited for enterprise deployments are built for high-performance, low latency workloads. Check out its detailed specs below:

2. ASUS WS C621E SAGE:

Check on Amazon Check on Newegg

This motherboard is ideal for multi-GPU workload and supports up to 4 GPUs together. It supports expandable connectivity options, including U.2., M.2, USB 3.1, plus Type C & A, and supporting Thunderbolt EX3 cards. We highly recommend this for home server setups and is not ideal for Enterprise Environments. ASUS provides their proprietary Control Center management interface for complete, centralized server management which we found out to be quick and easy to use. There is a ‘Full Nickel‘ square socket P Water-block available. Check out the specs below:

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.
