Asus rampage x48 lga 775

I seem to be in a little bit of a weird position here with this board,
asus rampage x48 lga 775 slot
it seems the asus website is houseing old drivers compared to what I see
on the intel chipsets website?
My question is what version should i be running?
I was under the impression that since this is a asus board I should be using
there board and chipsets drivers? Am I mistaken?
Someone please inlighten me with some useful information on this subject please thankyou

Since the board uses an Intel X48 chipset, you're always better off getting the latest INF files directly from Intel. The latest INF Update Utility is v9.​1.​1.​1019, available here...

INF Update Utility -​ Primarily for Intel® 5, 4, 3, 900 Series Chipsets

Thanks when I did the update only the ata drivers uprated so I'm assumeing everythngs fine
with chipsets you don't uninstall the old drivers it does all that itself right? All done via intel installer
