If that is how you want it set. sure.

So what are the PSU PEG1&2 figures? They are the only ones more different than your recomanded values?

How much power the card is allowed to pull from the pci-e cables.

I was helping a friend out with his 980ti classy. This may be useful. One of our goals was to eliminate the need for PX16 or MSI AB.

Final question; since I'm altering a "percentage" for power limit, will my card just draw more power when the clock demands it all the way up to that point, or will the "power target" field in apps like Precision now be increased from the usual 106% to a higher number that I can change as needed?

It will now be increased to 120% from 106% and you can change it as needed. Also power limit needs to be...
 
Power Limit:
150000
250000
300000
 
Not 100000 on the first one.

Ok.... So got my power limit increased, and my slider in Afterburner goes to 125% now instead of 106%. But it's not allowing me anymore increase in core clock than before; I noticed also that my voltage on the core is also not increasing anymore than it was, and I clearly need this to gain some more stability. I'm getting +135 on the core right now stable, which is on top of the already +109 the card is stock with so all in all about +244, which isn't bad; it's in line with what my 970's were doing. But I could achieve this current increase on stock BIOS no problems and the power limit increase isn't enough.
 
How would I go about changing the voltage for this card (the eVGA 980 Ti SC+) to gain some more stability on about an additional 75Mhz core increase? I'm comfortable increasing up to 1.3 - 1.315 V on the core, but not anymore with my stock ACX 2.0+ cooler on there; I may water-cool if I have success in increasing clock and voltage and see the need for it. I usually turn my fan up to at least 70 - 80% when I game anyways so I'm okay with accounting for the extra heat that the additional 1V could bring.
 
To summarize; I'd like an additional 500 - 800 mv added to my core from the default allowance of 87mv . Is this something that can change and be icnreased with the slider in an OC application as well like power limit? Or must it be modified statically in the BIOS tables?

Statically. Max for your card is 1.28v. The following will need to be changed inside the vbios to make the card run at 1.28v...

Perfect! That really should be all I need to just go for it on my own at this point and really see what I can hit. Do you have any reservations with setting it all the way to 1.28 considering I'm using the ACX2.0+ cooler that came with the card? As I said, I'm ok with turning the fan up when in games. I'm staying pretty cool under load currently already, between 56 and 63 C. I think that's plenty of room to increase voltage that much; considering I've another 30% fan speed to compensate if needed.

Sounds like you'll be fine.

No luck :(
 
When I set that voltage table you showed to 1.28, my card was constantly staying at that voltage, but as soon as I launched a 3D application (Unigine Heaven in this case), I get a crash, black screen, then, the weird part: The benchmark continues/restarts but the card got clocked down all the way to 565 Mhz and wouldn't change!!! It's like some internal throttling mechanism and not thermal throttling because I was at 48 C.
 
What's going on here? Rebooting was the only way to reset the GPU to not throttle at 565 Mhz anymore until I flashed my last BIOS back. DO the cards have something built-in to prevent a voltage increase of that magnitude? Because my card did NOT like it lol

Sounds like a unstable overclock.

You don't necessarily need to reboot, you only need disable and reenable the card or cards.
