Data dump of the last ~6 weeks of my HD 5000 testing. I'll soon post a brief data set of HTPC-oriented power in the MSI VGA forum for their 5770, 5570 & 785G as well as instructions on forcing the Hawk into continuous 0.950V_GPU operation.

more data--esoteric, photo shows pertinent power controller circuitry & includes feedback circuit components
MSI R5570-MD1G
efficiency in OCCT 3.1.0
overclock, underclock, overvolt, undervolt, system power (DCW), temperature, noise
V_GPU = 1.175V (set) --> 1.191V (load w/ OCCT 3.1.0) killed the front-end MOSFET (OnSemi NTD4909N) which sources ~75W max to GPU only, VRAM has separate front-end
