Build A Computer Like My Super PC

Motherboard

The Gigabyte GA-Z77X-UD5H motherboard I have in My Super PC is at the top of the class in Intel LGA 1155 motherboards. The quality and stability of the Gigabyte GA-Z77X-UD5H are extremely high. In addition, it provides high performance and a rich feature set.

The motherboard is the main system board for the computer. It provides the platform to which all the other computer components are mounted or connect. In addition, a number of capabilities are built into the motherboard, such as for sound, USB and FireWire.

The first consideration in selecting a motherboard is the processor type for which it is compatible. Not all motherboards work with all types of processor. The processor compatibility of a motherboard is identified by the "socket type" provided on the motherboard for installing the processor. This is a reference to the physical and electrical characteristics of the processor. Motherboards are built to physically and electrically accommodate a specific processor type. There are a number of socket types on the market made by both AMD and Intel, so it's important to know the best one for building your own computer. Some socket types may be on their way to being discontinued, others may be too new to try, and others may be best suited for purposes other than desktop computers. Processor types are discussed on my Processors page.

Several manufacturer's make the chipsets that comprise the essential functionality of a motherboard, including Intel, NVIDIA, and ATI. Each manufacturer will provide different lines of chipsets for a given socket type. The particular chipset used affects the cost and features built into the motherboard.

What makes any motherboard "good" is foremost its quality. A motherboard which is marginal under load or flaky under certain configurations is one to avoid, regardless of the features and chipsets that it supports. It's important to have a motherboard that is reliable and stable with any configuration of processor speed, with any number and type of RAM modules, and with any number of add-on cards. After quality, the motherboard should be able to live up to its full potential in terms of performance and capability.

Good motherboards worthy of consideration should include lots of built-in features. This should include plenty of SATA connections for connecting hard drives and optical drives (such as a DVD RW drive), USB 2.0 ports, IEEE 1394 (FireWire) ports, an Ethernet port and onboard audio. In terms of features, motherboards most often distinguish themselves by the number of USB ports and IEEE 1394 ports they support, the number of SATA drives they support and the quality of the onboard audio. It's not unusual to find support for PATA (the standard IDE interface) generally meant for connecting optical drives.

Most good motherboards come with support for RAID. RAID (Redundant Array of Independent Disks) is most frequently used by computer enthusiasts to boost the performance of the hard drive by using two hard drives in parallel, called RAID 0. The full capacity of both hard drives is used when they are configured to run in parallel. But for most PC users, the hard drive does not get used enough to make it a significant factor in the performance equation. RAID is appropriate for heavy disk usage environments, such as servers or video editing. For home use, RAID might be fun to try but the extra performance is not going to be worth the cost of the extra hard drive. This is even truer given that hard drives come with a large memory cache so disk accesses that hit the cache are virtually instantaneous anyway. RAID motherboards still support single hard drive operation. Other common configurations of RAID are RAID 1, which uses one hard drive as a mirror image backup of the other, and RAID 0+1, which combines RAID 0 and RAID 1 functionality.

Most good motherboards provide either five or six slots for add-on cards. Generally speaking there will be one or two PCI slots for use with PCI add-on cards, at least one PCI Express slot for the video card(s), and the rest will be additional general-purpose slots that supports some speed of PCI Express. PCI Express slots and cards can be made to support varying speeds, expressed for example as x1, x4, x8 or x16. A PCI Express slot and PCI Express card must be of matching speeds. For more information, here is an introduction to PCI express.

PCI Express slots can be version 1.0 or the newer version 2.0. A version 2.0 PCI Express slot, PCI-E 2.0, has a raw bandwidth of twice PCI-E 1.0, but generally this extra bandwidth does not translate into greater performance. Both the motherboard and add-on card must support the same version of PCI Express, 2.0, to realize any increase in performance. However, the physical characteristics of the two versions are the same, so different versions will work together, just at the version 1.0 bandwitdth.

Most good motherboards will support two video cards running in parallel. When the video cards are based on NVIDIA technology this feature is called SLI, for Scaleable Link Interface. When a motherboard has this feature it can support two SLI compatible NVIDIA video cards running together in parallel to increase performance. However, it is not a popular feature to use. Performance is better and cost is lower by using a single, more powerful video card rather than two of the next cheaper, less powerful video cards running in parallel. This feature is called CrossFire when it is supported for video cards based on ATI technology, and it is called CrossFireX when it allows up to four ATI video cards to work together.

One element of the motherboard is the BIOS. Among other things, the BIOS provides support for the different processor models within a processor type. As new processor models come about, new versions of the BIOS for a motherboard may be issued such that the new model is supported. As a result, it's possible to purchase a motherboard with an older version BIOS than what is needed for currently available processors. This is one reason for the "six month rule of delayed acquisition". It allows disconnects like this to work their way out of the retail pipeline. If you're using a motherboard and processor that have been available for at least six months, and you're using a high-volume reseller such as Newegg to purchase your components, then it's unlikely you'll run into this problem.

The motherboard I'm using is the Gigabyte GA-P55A-UD4P, which is a socket LGA 1155 motherboard.

My complete recommendations for building a computer with quality components at unbeatable prices is on my home page at Build A Computer Like My Super PC - Cost To Build A Computer. Here again are the recommendations for a motherboard!
Description Where I Would Get It Today Today's Price Comments
ASUS Z97-A LGA 1150
Amazon
$139.99 Free shipping! The Gigabyte GA-Z77X-UDH5 motherboard I'm using has outstanding quality and is a top performer. Unfortunately, it's been discontinued. This ASUS motherboard is very similar and would be my choice today. One difference is that the ASUS does not come with IEEE 1394, but it is cheaper and FireWire can be added for low-cost with a plug-in card.

TigerDirect
Varies Clicking the link takes you directly to the page for bundles and systems. All of the components in My Super PC were purchased separately so that I got exactly what I wanted. But if you come across a bundle you like then you can be sure that all of the components are compatible. Bundles typically include at least the processor and motherboard, but can include much more.
Combo Deals
Newegg
Varies Clicking the link takes you directly to the combo deals page. Once there you can search by category, such as "AMD Motherboards" and brand, such as "Gigabyte".
