What are the three approaches to selecting a motherboard?

1. Select the board that provides the most room for expansion.

2. Select the board that best suits the needs of the computer's current configuration.

3. Select a motherboard that meets your present need with moderate room for expansion.

What are the parts of a motherboard and its function?

  • CPU Socket - This holds the CPU or central processing unit of the computer. A CPU does most of the heavy lifting and thinking inside of a computer.
  • RAM slots - These hold the RAM, or Random Access Memory. RAM is the workbench in your computer, holding all of your open programs for you.
  • North Bridge - This chip is usually located right beneath the CPU socket and its usual functions are to communicate effectively between the CPU, RAM, Graphics Chips, and South Bridge on your computer.
  • South Bridge - This chip handles all the communication between all the other input/output devices on your computer (USB ports, mouse, keyboard, speakers, etc.) and the North Bridge
  • PCIe, PCI, AGP and ISA card slots - These slots are used to expand the capabilities of your motherboard, from TV tuners for watching TV to a better sound card for your 7.1 channel surround sound system.
  • Front Panel pin out - This is usually a group of 9 pins that connects the power and reset buttons, and the power and hard drive lights on the front of your computer to the motherboard.
  • USB and audio pin-outs - These connect to a cable that runs to the front of your computer so that you can have front facing USB and audio ports.
  • Back IO Connector - This is usually where you plug in most of your stuff on your computer and usually has your keyboard and mouse ports, USB ports, Video connector, audio jacks, network jack, among others.
  • SATA, IDE, and Floppy connectors - These connect up to the main storage devices on your computer, including your hard drive, DVD/CD drive, and of course, the floppy drive on the front of your computer.
  • BIOS - This holds the information your motherboard needs to start itself, and also keeps track of the current time.

Which motherboard is best for graphics software?

This is a tough question to answer for a couple of reasons. First off: There are a lot of motherboards to choose from and there isn't really 1 out there that is absolutely the best. Intense graphics design requires some of the best hardware you can get and the motherboard is only 1 of many things to decide on. The Video Card, Processor and RAM are probably the most important things you will need to choose. The higher the frequency of the FSB (Front Side Bus) the less likely it will be a bottleneck for your graphics. If you are willing to pay a lot of money for a really nice system I could suggest some kind of dual processor board, a PNY video card, and a lot of fast RAM. A good recourse for motherboards is www.mbreview.com There you will be able to find some excellent reviews on the latest motherboards. Some of my favorite brands are AOpen, Chaintech and MSI. They seem to be very reliable.

Asus, Gigabyte and Intel are three very good mb makers. If you're looking for extreme high-end, Gigabyte has a new MB with FOUR x16 slots, taking SLI to a new level.

If you are looking at using Vista, it's the video card(s) that need the attention, because available RAM is limited to less than 4MB, so the big factor is to get onboard (unshared) memory on your graphics card -- you don't want shared memory, which is going to subtract from RAM available to the CPU. With Win7, this is less of a problem.

If you like AMD, the Gigabyte GA-MA790GP-UD4H looks pretty good on the high end. It has 128mb of "side-port" memory that, as I understand it, is dedicated to graphics. I don't think it's a bit deal but it is a plus.

What is a 20 Pin P1 Connector?

Many different connectors can have 20 pins. Some examples of these are:

  • ATX power supply connectors
  • JTAG cables (used for programming embedded devices)
  • A proprietary OBDII connector found in some BMW vehicles
  • HDMI cables / connectors (used for high-definition video)
  • Very old Apple floppy drives

What must be true before motherboard?

A motherboard must be modified to accept a particular type of memory, especially when dealing with multi-channel memory. On most motherboards, several types of modes can be configured to run at the same time. It is best to read the manual that came with your motherboard to find out how to correctly configure yours.

What is the difference between a motherboard and a daughter board?

The motherboard is the base board into which the others connect. It is central to the function of the system interconnecting all the rest while the daughter boards typically provide functions non-essential to the system being logically functional (with the exception that sometimes a processor itself is on a daughterboard).

Will a ddr3 1066 RAM work in a ddr3 1800 slot?

Of course, it could be run. It doesn't actually matter what type of ddr3 ram it is but what matters is the slot type and the ram type. DDR1 DDR2 DDR3 all have different slots. So as far as I think, It is going to work. Check it out and tell me..

What is the purpose of an AGP slot?

AGP (accelerated graphics port) slots are special slots on the motherboard specifically designed to take a graphics card (or video card as they're often called).

In recent years AGP has been replaced by the PCI-express standard (or PCI-e as they are often referred to) and thus AGP is generally considered an obsolete format. Even so, AGP hardware is still available, but often at an increased cost & with decreased performance.

AGP slots came in a few different speeds. The most common of which was 4X and 8X slots. 8X slots could utilize higher performance 8X cards. A 4X slot is limited to only 4X cards. However, many 8X cards have the capability to be used in a 4X slot, this will usually be denoted in the specifications of the card.

What three sockets are currently used for Intel processors?

775 - but almost phased out

1156 - for coewi3 nad core i5

1366 - for flagship i7

there are others for the xeon server chips (i think) but that's business and enterprise not consumer

How many devices are in the mother board?

Many different mother boards have been made to accomidate the latest microprocessors. I would say there have been 32 different mother board designs for handling the slot numbers of the processors.

How would I connect an internal 3.5 Floppy disk drive to a motherboard that doesn't have a ribbon cable connector?

Use an external USB floppy drive.

If you MUST have internal.... if you're good and creative you -might- be able to disassemble an external USB floppy drive and mount it like an internal drive.

Alternatively, you could hunt down an old LS-120 "superdisk" drive. Its an IDE drive (40 pin connector, like your hdd or cdrom) that reads floppies (in addition to high-capacity proprietary disks)

What is the function of the south bridge chip?

The southbridge is a chip that connects thenorthbridge to other components inside the computer, including hard drives, network connections,USB and Firewire devices, the system clock, and standard PCI cards. The southbridge sends and receives data from the CPU through the northbridge chip, which is connected directly to the computer'sprocessor.

What is the the major difference between integrated and non integrated motherboard?

Nonintegrated system board , each major assembly is installed in the computer as an expansion card. Major assembles we are talking about are items like the video circuitry, disk controllers, and accessories. It is hard to find them these days.

Integrated system board. Most of the components that would otherwise be installed as expansion cards are integrated into the motherboard circuitry. . They were designed for simplicity. Of course there is a drawback for the simplicity : when one of the components breaks , u cant just replace the component that's broken , the whole motherboard must be replaced. Although these boards are cheaper to produce, they are expensive to repair.

Difference between coprocessors and main processor?

A coprocessor provides auxiliary functions or features that the main processor does not have. These might include floating point support or hardware encryption. A coprocessor is generally not usable without its main processor, whereas a processor may function in a crippled or less powerful form without a coprocessor. An example of a processor and a coprocessor pair would be the 80386 and the 80387.

What could cause a motherboard to short circuit?

What you could be experiencing is is a short from the bottom part of the motherboard and one of the screws standoff in the computer case. First remove the mother board and notice all of the screws holes and examine the reverse side of the motherboard for scratches around these holes. if you find any use an insulator ( plastic or cardboard washer) on the underside of the hole where it meets the case srews stand-offs. Also check for screws already in place in these stand-offs that might be shorting the motherboard.

What Graphics card will work on a Asrock Motherboard?

More details would be required to answer this I'm afraid.

Ie the model number of the motherboard. From here, we can be of more use to you.

What video card is compatible with an Asus A7V880 Motherboard?

How do you remove the motherboard on a computer?

Step 1: Open the case and discharge any static by touching something metal.
Step 2: Disconnect all the wires in the case to get the m out of the way. Be sure you know how to get them all back in the right way.
Step 3: Remove all the expansion cards such as video cards, sound cards, and network cards.
Step 4: If your power supply is top mounted, it probably blocks the motherboard. If it does, remove it. Most bottom mounted PSUs don't cover the motherboard.
Step 5: Turn your case on its side so the motherboard is on the bottom.
Step 6: Take the heatsink off the CPU. Remove the CPU.
Step 7: Take out the RAM cards.
Step 8: There should be a number of screws holding the motherboard in. Unscrew them.
Step 9: GENTLY lift the motherboard out BY THE EDGES, not the back or front.

Note that everything in your computer connects to the motherboard, so if you replace it be sure that everything is compatible.

What are DIP switches?

A unit with several small rocker-type switches that plugs into a dual in-line package (DIP) on a printed circuit board.
