Which controller is your SSD attached to? Which SATA mode is it in?
You do not need the F6 Drivers. Just install Windows and then install the RST: http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=19607&ProdId=2101&lang=eng
Is it worth installing the latest RST divers? To get TRIM operating properly?
irst is not required for trim to work. the default windows 7 ide and ahci drivers support trim passthrough.
i have not seen any real world performance improvements or any other benefits from the irst drivers (i don't use raid). in fact, on one system the irst drivers caused stuttering during video playback. ymmv.
