I am using 1006. I have enabled MP 1.4 in order to get the IRQ numbers 16 and beyond. I am not sure how useful that is since several PCI IRQs are shared and there are lots of free ones. Anyhow, MP 1.1 works just fine too. I am using the Athlon MP 1900+ CPUs.
Note to anyone who is considering this cpu/motherboard, this combo uses *shedloads* of power. 400W is *not* enough (I've seen Alan post to this effect before but it bears repeating). Also, make sure you have good case airflow -- all that power that is being consumed is being turned into heat. Aftermarket CPU heatsink and fan are a good idea. Unfortunately, it is a bit crowded for 80mm CPU fans though.
Things are stable now once I mitigated the heat death problem.
