What is the difference between the Drivers? Which Driver should i use?
Depends on what you want, AHCI or RAID? Also, the coded text above shows an Intel INF utility version. That’s completely different from RST. Generally, the latest will do since you have a modern chipset.
@ Stoffi: Hello Stoffi, Welcome at Win-RAID Forum!
The first of your listed drivers is no driver. As plutomaniac alfeady has posted, it is an Intel Chipset Device Software package. So you only have the choice between both AHCI drivers, the Intel RSTe driver v4.1.0.1046 and the Intel RST driver v13.2.4.1000. You can take any of them.
OK, i will use the Mainboard for a Homeserver, so i think i use the v4.1.0.1046 Driver. Maybe it is optimized for the C220, because the other have 8 Series and C220 in the Name for the Device.
But i don’t understand what you say about the first Driver from the Chipset Package, why ist this not a driver? The 3 Drivers i have listed are possible to install, the Names you can see there are from the Device Manager AFTER installing.
When i use the Chipset "Driver", it renames the Device in the Devicemanager, but it use further the Microsoft Driver. In Driverdetails i can see the Path to "C:\Windows\System32\drivers\storahci.sys", Vendor Microsoft.
With the RST Driver it has "C:\Windows\System32\drivers\iaStorA.sys", Vendor Intel.
I can see its the same Thing with the Chipset Drivers for the System Devices, like SMBus Controller or PCIe Root Port and so on. They have all Microsoft Drivers in Background and are only renamed. But what is it good for, only for the right Name of the Device? Or does the Chipset Installer also install other software?
Exactly that. A lot of people think that Intel Chipset Utility (INF) installs drivers but it actually changes their name to something appropriate and more descriptive. If you install that utility, it will use the stock Microsoft driver just with a different name. To fix the names of other devices you need to install INF Utility first and then Intel RST drivers to use the iaStor.sys and not msahci.sys driver.
You need to install the latest Intel Rapid Storage Technology drivers to take more advantage of your hardware. Since you have a modern 8-series system, I suggest you install v13.2.4.1000 drivers which can be found HERE. According to Fernando’s personal testing these provide really good performance and responsiveness so try them out.
