Recommended voltage for Capcom IO board

[Arcade-Projects]

Hello,

Last night my Capcom IO gave me a scare by not getting recognized by the Naomi after several tries. I fixed it by cleaning the jamma connector but I also checked voltages and noticed I have it set for 5.2 volts (at the jamma connector).

I think I read it should be set to 5.1, so what do you guys recommend?

I swap boards a lot on my cab, cps2, cps3, Naomi, etc, so I'm looking for the best overal voltage setting.

Thanks.
