Basically, you get a list of potential combinations of engine clock, memory clock, and core voltage, plus a number of unknown flags. So far so good, but on some (especially high class) cards the entries do not vary as much as I'd like them to do, and many combinations do not exactly make sense. Others are repeated over and over.
Examples (engine clock in Mhz / memory clock in MHz / core voltage in Volt):
- RV770: 750/900/1.263 - 500/950/1.263 - 750/950/1.263
- RV670: 669/829/1.214 - 300/829/1.014 - 300/829/1.014 - 300/829/1.214
- RV635: 725/800/1.250 - 110/405/0.900 - 300/405/1.000 - 300/800/1.250 - 600/500/1.150
Also, the PowerPlayInfo V4.1 still has quite a number of fields we don't understand - marked as unknown in my AtomDis disassembler and table dumper.
