As I said, I wrote them myself - the closest analog to what I'm working on and polishing is WattTool for Windows, I think. Allows you to see VRM temps, set/get voltages, set/get offsets, change VRM switching frequency, and more - but WattTool can only give you this control over IR3567B and compatible VRM controllers. Mine supports four controllers that are used in AMD cards as main controllers (and sometimes this main controller is used for other purposes in the card besides core volts - for example, XFX RS 470/480 cards use the NCP81022's main output (VDD) for core (duh) but use the other one (VDDNB) for the IMC voltage (VDDCI.)) I've also added basic support for one controller that's more of a secondary one, which I found on my DirectCU II 290X. It controls MVDDC.
