Thought I would share this info here.
I got a Biostar NF520-A2 SE mobo for a simple build and the board was like $50 or so. Many many people on some OC'ing forums all stated that this mobo is terrible at OC'ing and some could not get a change from default settings on the CPU. I managed to get mine running at 3.029MHZ on air. I have not tried beyond this and wondering if i should on air. I probably will try to 3.2GHZ. So my setting is just 233 x 13 on the booster section. Have not touched the CPU VID yet. Running an AMD Black Edition 5000+ 2.6GHZ.
Just thought that I should put it out that this board is cheap but can be OC'd pretty decent.
