Hi Alacritan, I see I'm not the only sucker to buy this board. I got a 2200+ processor for mine and I have the same problem, although I have not upgraded to the f7a Beta Bios this could fix my problem. It could also fix yours, I don't know if you have installed it or not you did not say what bios you had installed, and here is a link to where you can download if you don't have it.

I have f6 installed in mine which should have recognised the processor But I think my processor is a clocked down 2800+ which is good.
The f7a Bios was designed to run the 2600+ at 266 FSB but that was before the Baton core came out there is nothing about them being able to run them at all, I had no idea that it could that’s why I got the 2200+, actually I ordered the 2100+ and got the 2200+ for a free upgrade. If you run this Bios on your computer it may start the FSB at 266 instead of 200 like mine did, it also started with a multiplier of 16.
I think that my mother board is a dud, I have had this problem with my mother board from day I got it and I was hoping that a processor upgrade would fix this, but has not.
Running 3D games on my system under winXP the games have this slow motion thing happening and you will laugh when I say that all I am running is a Geforce2, but I will answer that if a computer not even half the speed and with half the memory running a TNT2 can run it, why can't mine!!! It does not do this under win98.
Anyway I was wondering if you had a slimar problem or not.
Thanx
