Dell says my XPS 420 is not compatible with Windows 7 Pro X 64 but I'm running it just fine thank you.

I'm trying to tweak my system which boots off of two SSD's in Raid 0. Yes, it's fast.

I also have two 1TB application and storage conventional drives.

Bios is set to Raid of course even for the HDD's which are configured as Raid Non member drives.

Would I benefit from installing the Intel Chipset INF driver from the Intel website as Dell only shows chipset drivers for Windows Vista?

I also run the Intel Rapid Storage Technology software and drivers to manage the Raid 0 array.

So would the XPS benefit from having the Intel Chipset drivers for the ICH9R  SATA controller and the X38 chipset version?
