Please tell me where to get this wonder-patch. I've used George's (was that his name) PCI latency patch, but I haven't seen anything official. The problem is still quite noticeable for me as I have a RAID 0 array on a PCI controller. As I understood it, the flaw affected the entire PCI bus, not just PCI IDE and RAID cards. Please correct me if I'm wrong, though.
That said, I have a KR7A right now. The first arrived DOA, but the second has been working OK. I was expecting the difference between this and my AMD761 board to be a little more dramatic, but I've been unimpressed with the KR7A (unimpressed, not really unsatisfied). I have had some problems with the board not booting occasionally, but I'm not sure what's causing it, yet. With the botting problem and the PCI latency, I'm thinking of going back to my Epox 8k7a, which never gave me any problems.
So, I really don't know what to recommend to you. I really don't know what to do with my own machine, as VIA and AMD go hand-in-hand and I really hate recommending any VIA board (I've had bad luck in the past as well, if my luck had anything to do with the piss-poor performance of a few of my past VIA boards) and my experience with any of the other AMD chipsets (Ali, SIS) is extremely limited.
Sorry I can't help too much. Had to type that for some reason....
