South bridge over heating

download the drivers form www.via.com.tw/en/products/chipsets/southbridge

With limited info. No Laptop Make, Model? When did you purchase? "South bridge" doesn't tell me much? What is the make of the motherboard? It' may be cheaper to replace the laptop? If it's a Toshiba , what model? What date? Did you buy it new or used? And, by the way, hold off on the Arson, for now, the Headquarters will always be there.

It is extremely difficult to replace a Southbridge chip unless you are very confident with electronics repairs. The fact that you are asking questions about it on here would indicate you lack the required skills. The only way round this is to replace the motherboard- upgrade at the same time.

Intel 82801 refers to the Southbridge chip, of the motherboard chipset;
for an Intel 800 series motherboard chipset, for the Intel Pentium 4 series processors,

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Pentium_4_chipsets

Notice in the chart under the heading - South bridge;
ICH2, and ICH4 and ICH5 and ICH5R

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Southbridge_8xx_chipsets

Does NOT state anything exact about the motherboard.
For this you need the Model Number.

Granted the Southbridge chip, of the motherboard chipset; is what handles the Slower capabilities of a computer.

Audio is one,

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

[Note CPU = Central Processing Unit. Another term used is Microprocessor, or simply Processor for short.
Does NOT mean personal Computer.

This technology applies to YOUR motherboard, and not to motherboards that support the Intel Core i3, Core i5, Core i7, and Core i9, processors ]

However the Southbridge chip handles Audio through the Audio chipset.

Driver: Small piece of software that allows the Operating System to communicate with a device

The device is the Audio chipset.
You didn't state what Windows O/S you are using.

The reason BIOS doesn't detect the Audio chipset, is because the Driver is gone. Audio driver.

(Windblows lost the address to the driver)

IF, I have the model number of the motherboard;
Or,
IF I have the manufacturer name of the computer, and it's model number;
I can look to see if Audio drivers are available, and instruct you how to download, AND install.
I also need the Operating System used.

Windows what?

Scroll down, click on the Red -

Use a BGA Rework Station like the above.

Going to use a good Southbridge chip from another motherboard, that is the same?

Yes.

Removing a good Southbridge chip is redundant.
Buy one? MAY be possible.

By the time you have a BGA Rework Station used, the cost may equal, or exceed the cost of a replacement motherboard.

Oven / Torch /Heatgun method? Yeah right.
Temporary repair at best.

For the Dell Optiplex GX150 Desktop PC?

http://support.dell.com/support/edocs/systems/opgx150/en/ug/specs.htm

Motherboard chipset: Intel 815E

Northbridge chip: Intel 82815
Southbridge chip: Intel 82801BA

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Pentium_II.2FIII_chipsets

Under the subheading - Chipset - scroll down with your eyes to -
815E

Look to the right.
You will see - 82815 - under - Part Numbers.
That is the Northbridge.

To the right of that, you will see - ICH2 - under Southbridge.

Scroll the page down, until you come to the BOLD heading -
Southbridge 8XX chipsets.

You will see ICH2 is Intel part number - 82801BA

The I/O controller hub is in the Southbridge chip.
I do not know what the Super I/O chipset is.

[ The Northbridge chip should be under a finned Heatsink. If so, you will not be able to see the Intel part number.

Looking at the motherboard as a map, with the Processor to the Top, and Ram Memory slots to the Right, the Processor is NORTH.

(Ram Memory slots are to the EAST)

Coming down the motherboard, the Northbridge chip is under the Processor.

Come down further, and slightly to the right, and you will see the Southbridge chip.
It has Intel 82801BA on it, with other Intel information ]

HOWEVER, here is a list of Super I/O chipsets,

[ It comes up to the Wayback Machine. Wait a couple of seconds, and the Super I/O chipset page will come up ]

If this is a general question about the Northbridge chip, Southbridge chip, and Super I/O chipset;

Motherboard diagram,

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

CPU stands for Central Processing Unit. Another term used is Microprocessor, or simply Processor for short.

The Processor communicates with the Northbridge chip, through the Front Side Bus. (FSB)

The Northbridge chip communicates with the Southbridge chip, through the Internal Bus.

The Southbridge chip communicates with the Super I/O chipset through the LPC Bus. (Low Pin Count Bus)

The Northbridge chip handles the faster capabilities of a computer.
It handles the Processor, Ram Memory, and HIGH-speed graphics.

AGP (Accelerated Graphics Port), and PCI-Express, are HIGH-speed graphics.

A graphics card inserted into a PCI slot, or Integrated Graphics, is
NOT high-speed graphics. This is handled by the Southbridge chip.

The Southbridge chip handles the slower capabilities of a computer.

IDE
SATA
USB
Ethernet
and Audio. (Sound)

This is more information on the Northbridge chip,

http://en.wikipedia.org/wiki/Northbridge_%28computing%29

For more information on the Southbridge chip, simply left-click on the blue - southbridge, in the end of the first sentence.
(....the other being the southbridge)

You can also search the following in Wikipedia, by typing them in the search box to the upper right, and clicking on the magnifying glass icon.

It is a heat sink for the chipset which is part of the architecture of the CPU Board. You may have two chipsets called the Northbridge and the Southbridge or one chipset.
The Southbridge is the I/O Controller Hub (ICH) which handles the PCI/ISA/PCI-X Bus, DMA, AC'97 or Intel High Definition Audio, Real-Time Clock, Mass Storage Hardware (Hard Drives, DVD Drives), Key Board, Mouse, and BIOS (Basic Input Output System).
The Northbridge MCH (Memory Controller Hub) or IMC (Integrated Memory Controller) handles memory and communicates with the CPU, RAM, BIOS ROM, PCI Express Accelerated Graphics Port and Southbridge Chipset.

85 to 95 is ok. Anything higher than100 is pushing it. If possible add a fan to the side of the system case (Best choice) or you can buy a south bridge fan. You're MB doesn't have holes in the MB to attach a chipset fan but you can still attach a cooler on to the chipset. Like this fan; http://www.newegg.com/Product/Product.aspx?Item=N82E16835103155
And you'll need this as well for a good bond; http://www.outletpc.com/c2019.html

Enjoy!

I do not the north bridge of this motherboard is different from others. mainly ram ports and Graphics card pord is called north bridge. read it for more. ( click here )

Do not rate this suggestion; I am trying to clear my work queue.
