Can't OC NB past 2200mhz

[taydee]

Hello, I'm currently using my ol' Phenom II x4 955BE (C2 stepping). I currently have it overclocked to 3.6 @ 1.375v and the NB overclocked to 2200 @ stock volts. I'd like to try and raise the NB more because I hear it can bring significant performance increases with deneb chips.

The problem is, whenever I try to raise the NB/CPU frequency even to 2400 I get post followed by a screen saying I need to revert settings. Doesn't seem to matter what I do with the voltages, I just get this screen telling me to pick a cmos or revert to last safe settings.

Does anyone know what I'm doing wrong here? I've heard of people getting close to 3000mhz on the NB with this cpu.

Bump (if you're not allowed to do that here, please let me know). Still can't get my NB-CPU past 2.2ghz. Anyone have a similar problem, a solution, or related advice?

I'm wondering if it's related to my mobo. I think I'll try flashing the latest bios and see if that helps.

Well looks like I may have answered my own question. It appears that NB can only be increased in relation to cpu speed (assuming this post is correct). Guess I'll try to hit 3.8!
