Updating sis chipset driver
Those drivers are often more recent than the drivers you can download from the maker of your computer or motherboard. For most chipset drivers, you do not need to uninstall your old chipset drivers before installing the new ones.
The process of installation is usually quite simple. The cases where you need to uninstall first are noted in the table below.
They just use the name of the northbridge (the main chip) and ignore the southbridge (the support chip).
In most cases you find chipset drivers only by searching for a package which matches the name of your northbridge.
Your motherboard contains a CPU, some RAM, and expansion slots.
But it also contains some silicon chips which make all of those parts work together.
The northbridge is the main chip which connects to the CPU and high-speed expansion slots.Or if you don't like installers and declining included software then just download the zip file and unzip it.In the exceedingly rare cases where CPU-Z doesn't work you can try Sandra Lite. CPU-Z uses the term chipset rather than northbridge.AGP slots are especially susceptible to flakiness caused by old chipset drivers.
Even if you don't have an AGP motherboard, it's a good idea to be sure that your chipset drivers are updated to the latest version.
It is fairly common for computers to be running with old chipset drivers or to use the basic default drivers built into Windows.
