What is a motherboard / socket / chipset?

The motherboard is the main printed circuit board in a computer. It contains sockets/slots that all other internal PC components are plugged into, either directly such as the CPU, graphics card and RAM, or with a cable such as the hard drive, power supply and power button on the front of your computer.



The CPU/processor plugs into the socket of a motherboard. Current Intel Core 2 Duo/Quad and Pentium Dual Core CPU based motherboards use socket LGA775, officially known as Socket T, but the new Core i7/Nehalem CPUs use a different socket called LGA1366 or Socket B. Older Pentium 4 and Celeron PCs use Socket 478.

AMD, another CPU manufacturer and competitor to Intel, use Socket AM2 for their Phenom CPUs and newer Athlon 64 CPUs. Older Athlon 64s used sockets 939, 940 and 754. Socket AM2+ adds more features to AM2 but is compatible either way (you just lose any extra features). Socket AM3 has been delayed but should replace AM2 in 2009. Socket AM3 CPUs will work on AM2 motherboards but not the other way round, while DDR3 will also be supported along with DDR2 (not at the same time).

This website lists all the current and previously available sockets,



The computer chips on a motherboard which determine most of its capabilities and features is called the chipset. A motherboard will have 1-2 chipsets whose designs are given by the CPU manufacturer (e.g. Intel/AMD) to the motherboard manufacturer (e.g. Gigabyte/Asus) to make.

The motherboard manufacturer will then create different models based on these chipset reference designs. e.g. Gigabyte has the EP45 series of boards including GA-EP45-DS3, GA-EP45-DS4P, GA-EP45-UD3R, and many more, which are all similar in design but offer different features. These motherboards all based on the P45 (northbridge) and ICH10/R (southbridge) chipsets.


The motherboard's chipset mostly determines what other PC components/parts are compatible with a computer. The northbridge will accept only one type of CPU (in the socket), and determines the type of graphics/GPU and RAM that is usable. The southbridge connects the rest of the motherboard (to the northbridge) including ports for PCI expansion cards, hard drives, DVD/optical drives and USB, controlling most of the slower data I/O (in/out) functions on the motherboard.


Older PCs will have motherboards using chipsets which need DDR1 RAM, AGP graphics, IDE hard drives (no SATA), along with maybe an Intel Pentium 4 (Socker 478) or AMD Athlon XP (Socket A) CPU. Some PCs also have a mix of technology such as e.g. newer PCI-E graphics but use only older DDR1 RAM.

New PCs usually have motherboards using chipsets requiring DD2 RAM, PCI-E graphics and SATA hard drives (also most have at least one IDE port), along with a Dual Core CPU such as an Intel Core 2 Duo or AMD Athlon64.

Recently released is the X58 chipset which uses all new DDR3 RAM and the new Intel Core i7/Nehalem CPU using socket LGA1366. The X58 still uses PCI-E graphics and SATA.

Future chipsets from Intel, due near the end of 2009, will use Nehalem based CPUs but with socket type LGA1156. This will be when Core i7  drops in price and goes mainstream, with dual-channel DDR3 and Dual Core CPUs in addition to the Quad Core.


Current Intel chipsets

Current chipsets for Intel Core 2 Duo/Quad CPUs include P45, G45, P43, G43, G31, X48. While the new X58 chipset is for new Core i7/Nehalem CPUs. The G indicates integrated graphics (e.g. on the GA-G31M-S2L ) while X are performance motherboards for high-end use.

The most popular chipset today (end of 2009) are called P45, which replaced the P35 chipset motherboards. The EP45 series of motherboards is a newer version of the P45 from Gigabyte indicating better Energy savings. The P43 cuts a off just a few features from P45 but other lower number chipsets such as G31 are much more basic motherboards.

Older Intel LGA775 chipsets were based on 965 and 945, but there were also some 945 chipsets which used the Pentium 4 Socket 478. The oldPentium 4 CPUs had chipsets such as 955, 945, 865, 840, 810 and many others.

Current chipsets from Nvidia include nForce/GeForce 610i/7050, 630i/7100 and nForce 650i and 680i. Nvidia are most popular for their graphics/video card designs but have also designed motherboards for many years. Their graphics chipset is called GeForce and their motherboard chipsets are called nForce.

CPU - Bus rates

FSB = Front Side Bus, motherboard supports up to this speed CPU in MHz. Aussie PC Fix now only sell LGA775 motherboards which support at least 1333MHz CPUs, covering all mainstream CPUs (some of the pricey extreme CPUs run at 1600Mhz). If your motherboard only supports e.g. up to 800MHz then an E8400 running at 1333MHz will not work - you must upgrade to a 800MHz CPU only such as E5300 or replace the motherboard for one with better support.

Some motherboards say e.g. 1600 FSB (O.C.) which means compatible with overclock but the CPU may not actually run at this higher speed, check motherboard CPU and RAM compatibility before attempting to run a performance CPU at 1600 MHz.

= New LGA1366 motherboards use 'Quick Path Interconnect' instead of a FSB. It runs at up to 25.6Gbsec which is theoretically up to twice as fast as vs. 1600 FSB.



DDR2-1333 = Supports e.g. DDR2 RAM up to the speed of 1333 MHz. All DDR2 mainboards listed support at least 800 Mhz which is the most common type of RAM in 2008-2009. All new computers use DDR2, expect the brand new Core i7 and some AMD based PCs which use DDR3 but these platforms are not mainstream yet due to their recent release and cost.

Most users do not need to be concerned with DDR2 speeds as long as the board supports a minimum of DDR2-667 or DDR2-800. Most Intel dual core CPUs run at quad-pumped 1333MHz which is equivalent to dual-pumped DDR2 RAM running at 667MHz, so you should use this speed RAM or faster.

DDR-800 is the most common type of RAM, so it is best if your motherboard supports at least this speed (most do). You only need any faster RAM if you want the fastest possible speeds in your computer - but at a high expense, or if you will overclock past this speed (overclocking voids your warranty!).


Integrated Graphics / onboard video

DVI-D = Video output connector from the onboard video to LCDs with DVI connector

= As above but for older monitors (most CRT and some LCD)

= New LCD monitor or TV connector becoming popular especially with LCD TVs.

Display Port
= A brand new LCD monitor or TV connector that is not yet widely used

- Having onboard video means you do not need a separate graphics card. This is fine in most cases for video, graphics and many games, but to play the latest 3D type games then a graphics card will give better performance or is required. Motheboards with onboard video also include a graphics card slot so you can upgrade in the future if needed.


Graphics Cards / Video Cards

AGP = Older type of Graphics Card Slot still in use by many PCs tooday. AGP cards are rare and cost more than newer PCI-E cards.

= Graphics Card Slot that is most common since approx 2006-2007. Not compatible with AGP.


Hard Disk Drive \ Optical Drive ports

= Older type of drive port, for hard disk drives and optical drives such as DVD. Two drives per IDE port.

= Most common type of disk port. Nearly all SATA mobos have at least one IDE port too. One drive per SATA port.

= SATA2 but also has extra RAID function for hard disk redundancy (RAID1\5) or increased disk speed (RAID0)

= an external SATA hard drive port used in some new external hard drives. Faster than USB but not widely used yet.


Other Ports

RJ-45 Network connection. All new mothboards above have one or two gigabit (10/100/1000mbit) LAN ports
USB2.0 = Very common external port for USB devices/peripherals such as Printers and external drives.

= Firewire is a less used external port for firewire devices such as video camcorders

- Motherboards usually also include headers for addtional 1394 or USB ports - ask us if you need any more of these ports!

Legacy Ports

= Older port mostly used for dial-up modems and other serial devices. Mostly replaced by USB

= Older port mostly used with older Printers. Mostly replaced by USB

= Older mouse and keyboard connector (round and green/purple!) but can still be more reliable and convenient than USB (especially when troubleshooting PCs and the BIOS!).

- All motherboards listed above have 1x PS/2 mouse and 1x PS/2 keyboard connector unless otherwise stated

- Most new motherboards do not include legacy serial or parallel connectors as standard, but offer a header to attach an external port at the back of the PC at extra cost. Ask if you would like these ports, or additional headers for extra USB ports

Form Factor

ATX = Standard sized motherboard of size 30.5cm x 21.0cm to fit standard midi-tower case. Will usually have more PCI-E and/or PCI slots than a Micro-ATX motherboard.

Micro-ATX \ uATX = Smaller sized motherboard of size 24.4cm x 19.3cm which also fits in smaller mini-tower cases (as well as larger cases of course!). Usually cheaper and with less features than full ATX motherboards, but also commonly include integrated graphics for non-gaming computers.

Mini-ITX = Tiny motherboards used mostly for HTPCs (Home Theatre PCs) or when smallest fooprint is needed, with size of 17cm x 17cm. Also known as EPIA, most mini-ITX motherboards include a processor already soldered on to the board.

XL-ATX = Massively large motherboard with dimensions of 34.5cm x 26.2cm. Few PC cases fit this huge motherboard.
