I'm using 2 sticks of corsair PC 3200/400/512meg @ 2.5V. I have a stick of
Kingston, same speed/size but 2.6V. If I put the Kingston in what will the
2.5V set up do. Just slow the 2.6V ram down a little? Or would I be better
just to bump the voltage to 2.6?

2.5V is within the +-0.1V tolerance range of 2.6V modules.
Your bios might tell you what your current actual voltage
reading is.

So using the 2.6V with the 2.5V shouldn't cause any problems. When I put it
in it seemed OK I only took it out because of the voltage difference.
Thought I'd ask the group for an opinion. Thanks.

Since you have the option to set the voltage to 2.6V, do so.
2.5V for the others is simply the spec for required voltage
to meet the other specs, it is better to have them running
at 2.6V than to have the other running at 2.5V. In fact
many people find they need even more voltage to get several
modules running stabily, 2.6V should be seen as the minimum
and consider 2.7V if needed.

I disagree with Bob Day about +-0.1V tolerance, the listed
voltage can't be seen as a "ballpark", a target, rather it
should be seen as the absolute minimum ever used if you
expect stability at the spec'd timings. In a perfect world
this would not be the case but there is more to memory than
only IT'S specs (the motherboard's role too).

I'm not quoting the +-0.1V tolerance without a basis. See, for
example, http://www.elpida.com/en/products/ddr.html .
Of course, if you set the voltage near either end of the tolerance
range, it's important to check that the actual voltage supplied
is within tolerance. Power supplies have tolerance ranges in the
voltages they supply also, and the actual voltages are often lower
than nominal.

Something else to stir the pot. The manual states in the specs that the
board only supports 2.5v Ram. I know the voltage can be boosted.
