That isn't the model number of the motherboard.
It is on the motherboard usually towards the middle, on a GigaByte.
Starts with GA- and letter/numbers.
Usually in the middle of the motherboard, but may be on one edge, or in-between expansion slots, such as the white long PCI slots.
If you cannot find it, and the motherboard is operational, and the computer is internet ready, use Belarc Advisor for free,http://www.belarc.com/free_download.html
When you find it use the Gigabyte CPU Support List,http://www.gigabyte.com/support-downloads/support-downloads.aspx
[ I personally would use CPU-Z. MUCH more detailed info.
You need to know;
A) What processor socket is on the motherboard?
B) What motherboard chipset?
C) What BIOS version, and date, would help.
1) Processor socket:
No brainer. The processor has to fit in the processor socket, and the processor socket must support THAT processor.
[ Power, Signal, and Ground socket holes, must match up to the Power, Signal, and Ground, contact pins of the Processor.
Or other way around if the processor socket has the contact pins ]
2) Motherboard chipset:
I'm just guessing this isn't a motherboard that supports Intel Core i processors. Therefore the motherboard chipset has a Northbridge chip, and a Southbridge chip.
The Northbridge chip handles the faster capabilities of a computer.
It handles the Processor, Ram Memory, and HIGH-speed graphics.
[ AGP and PCI-Express are High-speed graphics technology.
A graphics card inserted into a PCI slot is Not high-speed graphics.
Integrated graphics is Not high-speed graphics either ]
The Southbridge chip handles the slower capabilities of a computer.
A) IDE devices
B) SATA devices
E) Audio (Sound)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.
Let's use an example of an Intel motherboard chipset. An Intel 945GC,http://en.wikipedia.org/wiki/List_of_Intel_chipsets#Core_2_chipsets
Here we see the Processors supported in the chart. We also see the Front Side Bus support. (FSB)
It's 800MegaHertz. (800MHz)
You also see the Process Support. 65nm
(nm stands for NanoMeter. One billionth of a meter )
Let's say I wanted to use the best Processor, that this motherboard chipset will support.
That would be an Intel Core2 Duo that is based on the 65nm architecture, and has an 800MHz FSB.
I would then look at a chart for the processor that is currently being used, and see what it's Voltage Range is.
From the above information, I would know that if the processor I want to use, has the same voltage range.
1) Fits the Processor socket
2) Has same Process Support. (nm architecture)
3) Has no more than an 800MHz FSB.
4) Falls within the same voltage range as the current processor being used ]
Awaiting motherboard model number. Post back in a Comment.
