I use one currently and used one with the Opteron 146 I used to own. I never held back because of the fact I used a converter and I have never once had issue either. I took my Opteron 146 all the way to 2.87GHz with stability using a 500W X-Connect, Ultra-D and a converter. A slight voltage droop is common, definitely don't worry about 0.01 volts. Push on!
