No real standard answer vis-a-vis voltage. Some chips can stay stable on really low voltage (i.e., for K8 939s such as you Opteron, 1.28-1.32V), and many require really high volts (1.45V and above).
The only way to know for your specific chip
is to subject it to testing.
Sorry for a non-specific answer, but this has been dictated by my experience with many of these chips.
If you have any problems or questions, of course, just ask away.
You can also come visit the Socket 939 Appreciation Club and Knowledgebase
(the link is also in my sig), where there is an entire community of friendly people with tons of experience with this family of silicon.
