Does AGP Voltage affect O/C?

depends
some people insist that the AGP voltage in an intel board is directly related to the NB voltage, and will help an overclock. Others insist otherwise.
In my experience, raising the AGP voltage increases stability when overclocking, even raises a max overclock. So, I say yes. But just play with it yourself.

Use good sense in raising the AGP voltage. Don't turn it up to 1.8 or 1.9V. This will probably kill your card.

In some cases it can help with stuttering issues, and I've heard of ATI actually recommending it in such cases (Rage3D postings, so don't quote anyone on that 
).
Keep in mind that it dictates the AGP controller voltage and not the voltage in the card itself so the AGP controller is likely to give out but not the card. Of course the AGP card wouldn't work any longer but a PCI card usually works... then you'd be stuck with lowend vid cards until a replacement mobo can be picked up though
Personally I've never seen an AGP controller fry, but as a rule of thumb, only raise it to alleviate problems, and only by as much as the fix requires. Usually anything less than 1.8v is fine.

I've had the quality of an OC affected by the quality of the thermal interface between the 9800 core and heatsink. Not that it made the OC STABLE - without AS3, I couldn't boot @ 262 bus, with I could. Neither was stable. And yes my AGP/PCI bus ratio was fixed.
