[lm-sensors] voltage reading too low: what next?

[james.kirkpatrick@imperial.ac.uk (James Kirkpatrick)]

    Hi,

I have just finished building a computer at uni. It has two dual core 
Opterons 275 on an MSI K8N-DL. It is very hot in my town at the moment 
and I would like to monitor temperature etc.

I *think* that sensors-detect is running all fine, the output I get from 
`sensors` is:

This suggest that the rail which ought to have 3.3V, provides only 1.9! 
Does anyone have any information about whether this is a real 
problem/artifact? What's my next step?

Thanks for any advice and for bearing with my ignorance!
