From the article "The PowerNow! Support will depend if your board supports or not FID_Command changing, if it doesn't, most nForce 2 don't seem to work, you shall need to edit registers with WPCREDIT" since most of the overclocking community for Athlons is using NForce 2 now, its a shame the author didnt check which motherboards can support this. Not a lot of use to me sadly. Hope it works for non NForce 2 peeps.
