I/O voltage....when do you know you need more?

[Killrose]

Do you need to: increase this in conjuction with the core voltage?, OR: lower core voltage and increase I/O voltage?, or: are there certain problems that indicate a need to increase this. This question is in relation to SocketA processors (see my sig).

The i/o voltage is for the motherboard (e.g agp, pci, ram) and only needs increasing if you're o/c your fsb. The core voltage is just for the cpu.

Therefore if your having stability problems when running on higher fsb settings try increasing the i/o voltage a little.
