Just wanted to note that the latest NVidia driver for the card (v361.91) and Windows 10 appear to functionally break NVidiaInspector's overclocking abilities. It used to be that you could prevent blue screen of death (BSOD) errors by running a program on the Nvidia card. But I've tried this with two different programs on running on the card and I'm still getting errors, specifically during full-screen gaming. The most recent ones have been a different BSOD error than we've gotten in this past: this time it's "System Thread Exception Not Handled (Nvlddmkm.sys)"
Pretty disappointed that it's been over a year and we still don't have a Sony rep even acknowledging this issue and saying it's built in becuase of battery safety or something. As is I'm getting noticable throttling on even relatively simple 2D games (Bastion, Child of Light, Toki Tori 2+) at temperatures in the 40s and 50s...
@hacktheplant I don't know if you're still following but you at one point mentioned that throttling happens even when not runnning Windows and said you'd experience it when the machine ran Android as well. Did you manage to make your system dual boot Android or do you have some sort of Android envrionment running on top of Windows? If the latter, would be curious to investigate possible Windows registry tweaks to try to fix this (though if the former that'd be useless and more likely a BIOS level fix like MrKazoo tried so long to find).
