Most of what I've read just tells the audience to put it at a certain setting, but don't explain what it does, how it affects overclocking, and how it affects MB/PSU. The piledriver/bulldozer guide that I've read over and over again and use as much as possible still gives recommended settings without really getting into what those settings do or how they affect overclocking. What's the difffernence between CPU CC being at 110% vs 130%?
You keep telling me about IBT and I keep putting it off. One reason for that is IBT was a PITA to even find where to download. Most of the places I've found were 3-4 year old articles. I did find and download IBT, but still I haven't installed it yet. I haven't even unzipped it yet. P95 is straight forward. I hit small FFT test and run for 10-20 minutes while heading toward my target overclock and then run custom with 75% ram for at least 1 hour. IBT, on appearance, seems to be a lot more complicated and I already have my head swimming with overclocking information. For someone like me who's usually running on little to no sleep, my brain will fry before my cpu ever does.
I completely understand how sometimes "New" settings can be intimidating. There simply isn't a lot of useful info around.
You're right on track starting with lower settings (110% etc) and following through till a given point in your OC. This is exactly how you learn your equipment with various combinations. It's also the same path I followed back when I was first bitten and again when learning this 9590 and CPU Power Thermal Control. To help get over the unknown be assured that as long as you don't just turn all the Digi settings to Extreme at the same time you most likely would not damage a PSU. You're more likely to encounter instability before damage. Work only one area at a time and note any changes in test results and failure times. 130% is simply where most have found the best results when starting out.
Here is the proper version of IBT AVX for the FX's http://www.overclock.net/attachments/13202
You are correct IBT is old, but it comes from approx the same era and tests using AVX.
It is available in many different versions, this one is for the FX series.
Version # is also important for Prime95 you'll want version 27.9 as all later version are moded for newer CPUs are are known for sometimes causing issues.
It's not that IBT is better than P95, only easier/faster to see changes in pos or neg results. If you post a snip showing HWInfo64 and IBT from link set to very high and 10 runs I'd be happy to help explain more what I mean.

If memory serves me right you are interested in C&Q. As you learn CPU Cur Cap and how it can affect things also consider Offset Voltage Mode. Only mentioning it again as it too can change things and better to get it handled early in the learning process as you may find that after a certain CPU multiplier setting C&Q may only function if using Offset voltage. It's this way on both my CHIV and CHV-Z.

I tried looking up CPU Current Capability, but can't find an understandable explanation for it and why you should or should not use 130% over 110%. Same goes for CPU LLC. To my understanding, you're looking for the setting that gives the least vdroop/vraise. So why does the Piledrive/Bulldozer guide recommend Ultra High? I even seen one person on ASUS ROG forum suggesting that setting CPU LLC on Medium is actually better.
From what I've experienced, setting LLC on medium or regular would mean that I'm running my CPU hotter on idle for no reason. Technically, High would do the same thing. While Ultra High does start higher than the manual input, it does increase during load and lowers back down during idle. But, with idle being higher than manual input, what effect does it have?
I've also tried to research what "fine tuning" an overclock means. Only found vague, if not nonexistent explanations. It's almost like a novice is expected to know certain things without those certain things being made available to learn.
Also, Sand, I've looked at Digi+ with A.I. Tune set to manual rather than DOCP and there is nothing for DRAM. It may be a setting that's only on 990 and 990x chipsets. I may be completely wrong. I just know that my bios doesn't have it. I have come to realize, however, that manual is better than DOCP when overclocking because DOCP does a lot more than allow me to pick my DRAM profile. According to the description it "optimizes" a bunch of stuff without explaining how it optimizes those things. The way I read the description is this: "May interfere with your overclock."
Again for CPU Current Capability info I do feel your pain.
For me (IIRC) it was a slightly noticeable increase in performance (this means actual IBT results improved) with a slightly lower required Vcore before instability set in with each increase up to 130%. On my setup next step is 140% and no benefit found at all.
The LLC effects you ask about are exactly what I have and are normal. If I understand the question. All my OC's run this way.
"fine tuning" a method of OCing where each of four areas (CPU, HTT/FSB, NB, Dram) is OC'd/tested independent from another to reach max clock for each area.
Next step/s is to combine these results/data (all achieved using minimum voltage) into a complete system OC. The key is starting low and working your way up with minimal voltage increases rather than the "Ole Brute Force" method and just throwing voltage at it and see what you end up with. How else would you know how little a chip can run on?
It may be my bad on the Dram settings when I mentioned them to be in the Digi area.
I believe I was thinking these (please forgive it was late lol)
Warning: Spoiler! (Click to show)
To get started (off DOCP) I enter what's on the sticker of the dram itself. Reboot/re-enter Bios and you can enter what the Bios is showing to fill in the blanks that were left on auto. Again this makes a good starting place that won't change once it's locked down. The more things kept consistent the better!
