You should do well with the DFI with most any chip you have - That is if the chip itself will go.
Just setup one of my 939's with a DFI Expert like yours and have it running H2O for now.

Set the HT speed no higher than 3X in the BIOS, this will help keep HT speeds under control. Some chips BTW CAN run a higher HT speed without a problem but that's not going to help you much if at all should you even try it, just keep it at or below 1000MHz at all times for stability as stated.

Normally voltages for 939's aren't much of an issue but be aware these chips tend to start scaling just after the 3.0 mark, this being based on the chip's core such as a San Diego. SD's will do that along with Toledo & Opty chips and the DC chips are kinda like Thubans in how they act.
If you can keep it cool an Opty should run fairly well but know that voltage & temp management is key to keeping it all running smooth and stable. Don't forget to keep the board's components cool too, DFI's themselves are fussy about temps.
