I just recently upgraded my board to the AN35(N) Ultra and I have been trying to figure out if I can OC my XP 3000+. On my old K7S5A Pro I had a few options for the fsb via HoneyX OC bios. On this board I noticed that there are only the 100>133>166>200. Right now I have it set to 166. Is the CPU clock Ratio the CPU multiplier? Any help with understanding this board and how it works would be greatly appreciated.

In bios:
Advanced chipset features:
system performance:set to expert
FSB frequency: start at default 166 and raise it from there
cpu interface: set to aggressive
memory frequency: set to 100%

CPU ratio/voltage control:
cpu ratio select is your multi

have fun!

Thank you. I will give it a try and let you know how it worked.

Is your cpu multi locked? Keep an eye on your temps. If your overclock becomes unstable you can raise your vcore a step at a time to stabilize. Oh, and keep an eye on your temps.

GrimReality, I did it all slowly to give me time to test it and see how it works. Right now I am at a 190 fsb with the cpu reading 2471 and the temps are at 42c. My memory timings are 7-3-3-2.5
I raised the V-core to 1.85 and this was done slow as well. At 1.65 my cpu temp was 35c and with it at 1.85 it went to 42c and seems to be holding at that. So far everything is running really good. My barton was a 2.16 so it's nice to see it run at 2.47 I wondered if I had made the righ choice in getting it, well now I know. Thank you for the info you gave on the board. It helped alot.

I think it is locked. When I change the cpu ratio it will still show up as 13 on Everest.
