For 1, 2 and 3:
Looking at the bios he gave you. Your base clock and boost clocks are all set to 1405. It will run at that clock unless you set your driver settings to adaptive, in which case it'll go into idle mode. Any stress on the GPU though, and it'll go back up to 1405.
Your memory clock is now set at 3705. That's 1852, roughly...
No. You now have a 320 watt TDP. The % shown in that row, will be the % of power you're running to that TDP setting in the bios.
He also gave you a 315 watt at 100% on the power target slider, and 320 watt at 102% on the power target slider for your new power limit. So, your slider is only going to go to 102% now, but it's still more than you had before, even with the slider at 120%. Smile, be happy.
Under boost conditions, your GPU will run 1.25v. With adaptive set in the driver settings, the voltage will scale down.
Vdroop is the difference between what the voltage is set at, and what the voltage the GPU core is actually using. It's not something you should be worrying about with your card...
If you want higher overclocks, having boost disabled can allow that to happen, as allowing the card to "boost" can cause problems...as you mentioned, the variance between one clock state and another can cause instabilities when pushing for very high overclocks. If you're more of a gamer, than a bencher.....use boost 2.0 and be happy.
Thanks for the in-depth reply. It pays to ask questions.
When Boost is enabled, when do the core and memory speeds get increased - when GPU % Utilization crosses a threshold ?
Does setting the Power Management Mode to Adaptive create additional instability ?
When GPU-Z reports the Perfcap Reason is "VRel.VOp", is that related to approaching 100% TDP or is it the voltage setting ?
The video card is connected with (1) 8-pin and (1) 6-pin PSU connections. Does that factor into the Maxwell II BIOS Tweaker settings ?
