My Motherboard = ASUS P8Z68.
Chipset = Intel Z68 Express
Driver Version = V9.2.0.
O.S = Windows 7 (x64bit)
Western Digital recommends using Intel driver version 9.6 or later for maximum performance. But the latest available driver on the ASUS website is Intel V9.2.0. If I run the Intel Driver Update Utility any update to latest driver version fails, any advice appreciated.
Have you try installing the latest Intel® Rapid Storage version 14.8?
Since your computer integrates an Intel(R) Z68 Chipset, this is PCH and the latest version should be compatible.
