It's CPU-Z from CPUID.com, but made especially for Gigabyte motherboards.
This way when you change a parameter in Voltages, or system bus clock, (FSB), you can see the changes in real time.
2) EasyTune 5 from Gigabyte,http://gigabyte.com/MicroSite/121/tech_20041125_px_et5.htm
That is just the features, and G.U.I. shown. (Graphics User Interface) The actual download website is below at the bottom link I listed,http://www.filecluster.com/Drivers/Firmware-Bios/Download-Gigabyte-EasyTune.htmlhttp://www.filecluster.com/downloads/Gigabyte-EasyTune.html
The above is the actual download page.
Where it states 7-Zip info, go to the right, and click on the blue - External Mirror 1 - (Has a green Down Arrow to the right of it.
After you click a small window will come up on the right -
Click on Save File. Observe the top of the small window that comes up on the left. In the wording at the top of the window tells you where the file will download to.
Go to where it states, then DOUBLE-click right on the file name,
Now follow the directions, and install EasyTune 5.
This is Gigabyte Support, and the download page for the motherboard manual,http://ee.gigabyte.com/products/page/mb/ga-m61sme-s2l_20/download/manual
1) Take -> BABY steps. Change a parameter in small increments.
Change the parameter in one small increment, then let the system (Computer) run for 24 hours. This is a 24 hour burn in test. Pretty accurate, but do not 'stamp it in stone'.
2) You can only overclock so far. Overclocking creates heat. After some time the air cooling you are using, is not going to be adequate.
3) You can only overclock so far because you will be changing the FSB for the Processor. This also changes it for the Ram Memory, and expansion slots.
Ram Memory typically operates at half of the Processor's FSB.
Change the Processor FSB too much, and ram memory will not work.
Neither will the expansion slots. Their frequency rate is determined off of the Processor FSB also.
4) Overclock too much at first, and you risk burning up the motherboard chipset, and Processor, and Ram Memory.
