I had some initial hassles with this board and an Athlon 64 3800+ X2, which disappeared after I bought a new power supply and faster RAM. I flashed to 1007 before installing, and used all the latest drivers (as of 01Oct05). I had to manually set the RAM timings (auto was wrong) and boost the voltage to 2.7V. After this I ran memtest86+ for 24 hours without errors. I also slightly boosted the FSB to 201MHz, as recommended elsewhere here, to avoid PCI bus synch problems, although I think one of the BIOS revisions fixes this problem.
The BIOS setup reported no SATA drives, but these were recognised by the RAID setup utility and I was able to create a bootable RAID0 set. However, I also had my old PATA drive installed and after an XP install, I couldn't boot to RAID. I solved this by re-installing XP without the PATA drive, and adding it after installing XP to the RAID0 set.
I'm running the NF IDE drivers, with no problems so far. I'm not using the firewall stuff, since it's been reported as flaky just about everywhere.
I had some application hassles, mainly to do with multi-processor incompatibility. I have managed to solve all of these using the Windows Compatibility Kit (V4.1) - the SingleProcAffinity fix does the trick. MS also provide a single processor affinity fix for broken interrupt device drivers (intfiltr), but I haven't needed this (yet?).
Overall, I'm very happy with this setup. I was expecting some problems, given that dual core is fairly new to the desktop scene, but the effort has been worthwhile.
