Could somebody tell me which Bios revision I should download from my manufacturers site to do a slic 2.1 mod. I have an Asus P4P800 Deluxe mobo with the original bios revision 1008 which is the oldest one. They have like 12 newer revisions out for this mobo all the way up to 1021 beta. Should I do the mod on the same revision that is currently being used in my bios or use an updated newer one?
