The vrms on the 970 won't handle that cpu long term.

You were using an extreme 3, right? And the mobo failed after OCing?

Can't make a blanket statement on a chipset regarding VRMs. Phase designs and VRM chips vary. Digital vs. analog, low-level drivers used, mosfet count, types of inductors used, and manufacturer (NXP and Vishay plus a crapton more). There are 4+1 phase designs that can handle more power than 8+2 phase designs. None of that shite is standardized and not even consistent across motherboard brands, chipsets, price points, or sockets, so there are people with much more time and expertise than I have who painstakingly scour data sheets and personally examine individual boards to classify and compile VRM information for overclockers. Not sure if that info/spreadsheet is still floating around or is up to date though. But I did find this general 'recommendation' sheet for AM3+ boards.

EDIT: Found the super-extensive spreadsheet: LINK
Unfortunately, it's only for Intel boards, and for some reason it's an image file, which is the worst format for this amount of data.
