The latest Intel® Rapid Storage version supported by the ICH10R is 11.6 and this is not compatible for Windows® 10
Also, I have checked motherboard's download site but I could not find Windows® 10 as compatible product: RAMPAGE III FORMULA | Motherboards | ASUS Global
Thanks for the reply, Allen.
I am aware that ASUS does not officially support Windows 10 as they have not released drivers for this board for years. My point was that all my peripherals have worked up until upgrading to Windows 10, including using the 14.6 Rapid Storage drivers with Windows 7.
With my simple workaround, everything is working flawlessly. If it is that easy, why can't Intel continue to officially support the chipset, especially with still relevant processors?
If Intel's official stance is no more support for this chipset, then it appears I am hosed. I will continue to use this workaround until I no longer can. At least this post exists for others in my predicament!
