We culled these questions straight from Google鈥檚 search results, and we hope these answers will help you as you鈥檙e learning more about server motherboards and servers in general.
Let us know if you have a question, or series of questions, about a specific topic that you鈥檇 like for us to answer in a future blog post.
Now, let鈥檚 get cracking.

A server motherboard, also known as a system board, main circuit board or main board, is what we at 萝莉社 like to refer to as 鈥渉ome base鈥� for your server. It鈥檚 home to all your server鈥檚 primary components, from the chipset to the PCIe slots to all those RDIMM sockets, with one of the most important components being the central processing unit, or CPU, often referred to as the brains of your server.
The server motherboard provides a platform through which each of the server鈥檚 main components can interact, and as such, the motherboard is quite literally the communication facilitator, the technological translator, of your server. We like to think of the server motherboard as a business consultant or a lobbyist, always ensuring that there鈥檚 an open line of communication between the key players of an enterprise, or in this case, the motherboard.
You could also think of a server motherboard as a jigsaw puzzle: its pieces come together to form a whole, and they all rely on each other to create a complete, usable picture. If a component is missing, so, too, is a unique, or altogether necessary, piece of the motherboard. When you take a component away, you鈥檙e taking away functionality, and depending on the criticality of that component, rendering your server completely inoperable.
Because every customer will have a different set of requirements, whether personal or dictated to them by a superior, this is a tricky question. So, while the following answer is somewhat of an obvious one, it encompasses the thousands of different possibilities for server motherboard configuration: The best server motherboard is one that meets your needs or fulfills any requirements and specifications that have been given to you, the buyer.
As mentioned in the answer to the previous question, there are numerous components that make up a server motherboard, and many of these can be changed to add and subtract functionality to and from your server.
For example, one powerful Intel Core or Xeon processor may be enough for a workstation application, but heavy-duty servers usually require the power of dual CPUs, since they鈥檙e providing high-speed computation and storing critical resources for other computers in a network. Likewise, some customers will not need a bunch of RDIMM slots, but others will. Why? Because more RAM would equal smoother performance for their application, or they may just want to have the capability to install more RAM down the line.
PCIe slots are another consideration, especially when you鈥檙e talking about high-end servers and workstations. If you have a slew of option cards that you plan to use to connect additional high-speed GPUs, hard drives, USB ports or Ethernet ports, or you would at least like to have the option to extend the functionality of your server down the road, then a server motherboard with a bunch of PCIe Gen 3 or Gen 4 slots is your bread and butter.
Always remember that what constitutes the best server motherboard is highly relative to the customer and dependent on numerous variables dictated by personal or enterprise-related requirements.
Don't worry, though. 萝莉社 can help you put the pieces of the puzzle together.
There are a few key differences between the motherboards found in high-powered servers and those found your traditional desktop computer.
Server motherboards typically have two processors, compared to the typical desktop motherboard鈥檚 one. As a result, the server motherboard has more cores and more threads with which to process data. In other words, the typical server motherboard can handle a higher computational workload than a desktop motherboard, and for good reason, given that most servers are often powering resource-intensive applications for the military, commercial and industrial sectors, and providing files and resources to many computers at once.
Server-grade CPUs are often from Intel鈥檚 Xeon processor family, which is specifically designed for high-performance servers intended to efficiently digest a considerable workload. We鈥檙e talking workloads associated with data acquisition, cloud computing, the control of weapons and communications systems, industrial automation and much more. Desktop motherboards, on the other hand, typically incorporate Intel鈥檚 less-powerful Core, Pentium or Celeron CPUs. These processors have their purpose, of course, but they鈥檙e not designed to handle the heavy-duty workloads tasked to data-driven servers.
You鈥檒l also find error-correcting code (ECC) RAM on server motherboards, which prevents data corruption through automatic detection and correction of memory-related errors. Given that this feature is designed to support enterprise-grade workloads and servers, it鈥檚 also supported by Intel鈥檚 Xeon processors. ECC is an important feature for military, industrial and commercial applications because it鈥檚 a data-protection failsafe. Other processor families do not support ECC.
Server motherboards typically have more PCIe slots than a desktop motherboard as well, or they鈥檙e designed to support a compatible PCIe backplane. This allows customers to add high-speed RAID cards, GPUs, additional USB ports, solid-state drives and much more, thereby extending the server鈥檚 overall functionality. This is an important feature to have should a customer expect, say, a need for a high-end GPU or additional storage capacity down the line.
Technically, yes. A server is a computer like any other, and with the right CPUs, graphics, and memory, gaming is a possibility. You鈥檒l need the right peripherals 鈥� a monitor, a keyboard and a mouse 鈥� and most servers come with more than enough input/output options for this purpose.
You鈥檒l likely run into some setbacks, however. Most servers don鈥檛 come with an integrated graphics card or sound card, so you鈥檒l need to purchase separate ones one to support your game鈥檚 visuals and audio. In addition, server-grade CPUs, such as an Intel鈥檚 Xeon Scalable processors, don鈥檛 have overclocking capabilities, and sometimes, they have even lower clock speeds than CPUs targeted toward gaming. Why? Because they鈥檙e typically powering data centers and mission-critical applications, which are expected to run 24/7 with no interruptions, and higher clock speeds typically means an increase in the monthly electric bill.

Otherwise, let's move on to the last frequently asked question, which addresses the different motherboard form factors out there.
Server motherboards are available in a variety of form factors, which are just specifications dictating a motherboard鈥檚 size, shape, mounting holes, power supply and other features. These include eATX, ATX, microATX, SSI CEB, SSI EEB, SSI MEB, COM Express or even a manufacturer鈥檚 custom form factor.
ATX is the most common server motherboard form factor, at 12 inches in width and 9.6 inches in depth, but you鈥檒l often see eATX server motherboards as well (12 inches by 13 inches), as eATX is designed specifically for rackmount servers that contain more components and circuitry than the smaller ATX form factor can house. MicroATX server motherboards (9.6 inches by 9.6 inches) are also available on the market for smaller server systems. Like ATX and eATX, SSI form factors can support dual or multi-processor motherboards, but they鈥檙e slightly larger in width or depth and have differing mounting holes and I/O options.
And that鈥檚 it! We hope we thoroughly answered some of your most asked questions about server motherboards and servers in general.
