FF is not an acronym for anything, it's just the highest 8 bit number. The post code byte counts up, so naturally the last one is used for when it's finished.

I am really enjoying my 780i, only problem I have is the A0 warm reboot error hole at 1625-1725MHz. Don't have time to waste doing the RMA dance more than once.

Hard to beat 8GB of cheap DDR2 while they flush the channel for DDR3, enjoy it while you can. No sense fretting over the impending 790i release as the only reason to own a 780i is for SLI, and you're not going to be system RAM BW limited in games anyways. It remains to be seen if the integrated nforce 200 bridge will make a difference. Or even if it's card to card features will matter at all until an actual new GPU comes out instead of more rehashed crap from 18 months ago.
