A + 0.025 offset gets me to 1.288v and a + 0.015 keeps me at 1.272. If this is unstable I will try the Ultra High LLC + 0.005 it hit 1.280v . I know I could use manual voltage but then i'd have to restart all over. LLC should not matter for stabilty fro ma setting point when using offsets if what I am told is true IE a +0.005 offset at extreme that maxes out at 1.288v and is stable should still be stable if it were a +0.030v offset on High and had the same votlages? Also is there anything wrong with negative voltages?
Also my temps peak at 72c atm however it is hotter the before and I used to get 68c a week ago. However I also wiggled my 212+ slightly because it was not a 90 degree angle, however most say that is common for the 212 to wiggle slightly ( I moved it 1cm or less ) that shouldn't have changed the temps right? ( Ambient atm was 23c, a week ago it was 3c when I got 68c )
Sorry, I am not really sure what you are asking with some of your questions, might be a language issue. Since you would rather find your oc without following the guide exactly, I can just say increase the voltage until you can go over 12 hours of Prime95 without any issues. Negative offsets are fine if your VID is above the needed vCore. I have no experience with the 212+ so I can’t comment on that. Just keep your hottest max core temp below 95c while testing, and shoot for closer to 80c for your 24/7 setting.

Is it possible that somewhere below 1.270 (the lowest voltage where I got a WHEA error after 15 mins) i'll find a voltage that can give me 12+ hours of prime with no errors, or is that not how it works?
Appreciate all the help so far justanoldman, this has been fun so far.
Stability is a goal not a destination because there are no 100% stable machines anywhere. The best we can do is make it as stable as possible for how we use the machine. Some people only run Prime for a few hours and then test with their other programs, and other do multiple Prime runs of over 24 hours.
Neither is right or wrong, people just have different ways of viewing relative stability. In my personal opinion people should be able to go at least 12 hours of Prime95 testing as shown in the guide with no instabilities or WHEA issues. Either way you still have to spend a week using every program/game you have to see if the oc remains stable.
My first chip needed 1.33v to stabilize 4.5 and there are others who report needing in excess of 1.35v, so 1.28v for you is above average but not really high by any means.

WHEA 20 in Apps and Services-Microsoft-Windows-Kernel WHEA folder, WHEA 19 in the top Administrative folder.
