VRM implications in performance?

I have been using the wrong VRM part with a system equipped with
2x Paxville Xeon processors and had experienced no problems.
I wonder if there is any performance loss because of this?
anyway in a few days I will find out when I get the right VRM ...

If it has a compatible range of (it's programmable) outputs
that the processor(s) require, or at least close enough to
not cause damage, and is capable of the current, it can work
ok.  We'd need to know the technical specifics of the two
VRMs to know if they are different enough to matter in some
other way (or at least speculate about it, for example if
one barely has enough current capability it might not last
as long but it's not like you could mark a failure date on a

If by performance you meant processing performance, no, so
long as the system runs stabily that difference will not
speed up or slow down the processor.  If the processor were
getting too high a voltage and that caused overheating, or
too low a voltage and it increased the required charge time
beyond a level possible based on the clock rate, that could
instead cause computational errors which may cause an effect
seemingly like stalling code if not outright indications of
errors like a crash... but you make no mention of this
happening, though it might be more likely at full load than
lesser load.

hi kony,

Many thanks for your explanation.
