x86, you might want to look at the posts on overclockers.com. There is an area for Intel ABIT motherboards in general, and another for the TH7II. I believe there's a "wire trick" that many are using to up the available core voltage. There is also a "hacked" version 77 BIOS that others are using (the pros and cons of which are discussed); there's a download link too.
You'll also see that there's quite a discussion there about DRCG's and BIOS versions (and another one here under Motherboards). I'm interested in knowing which chips and BIOS your board came with (and where you got it from).
Thanks and good luck! 🙂
