I get a bit compulsive with this stuff so write down the settings and every single result in a spreadsheet so I do see patterns.
As far as the PLL voltage, it's not conclusive by any means but, I was getting BSOD's at 48 multiplier at 1.45 volts with PLL set to auto and these were quick kicks after a minute or two. Since I set the PLL to 1.7v I pass both 1344 and 1792 and have gotten two 9+ hour runs on blend at 1.435v and 1.440v. I am now more than 9 hours into a third attempt, this time at 1.440v. BTW - the previous errors on my 9 hour runs were 0X7a and were due to hardware issues. I had to update my SSD firmware.
My advice, and take it for what it's worth, is to set the PLL at 1.7 and leave it there. If others are stable with this value then it evidently can't hurt and it could in fact help you get stable. Do the same with the other settings folks on this board suggest. Then adjust your VCore until you are stable or get too hot and need to back off on the multi. This seems to be working for me and I am getting a "feel" for when I'm close. Things do calm down when you get close to being stable so the inconsitencies you describe will go away eventually. Make sure you are checking the error codes on the BSOD's and check the OP (if you don't see them there do a Google search) on what these mean, it can help a ton.
I get 124 bsod's constantly during prime blend if my vcore is 1-2 notches below stable, ive tried changing pll, dram, and vccio, also putting all my vrm stuff to exreme, and playing with LLC and that, but nothing short of a bump in vcore fixes it,
for 4.5ghz i use ultra high llc, and -0.015 offset, the rest of the stuff is auto/default volts, if i go to -0.020 or -0.025 i could play around with pll until pigs grew wings, it still bsod's 124 every time (or sometimes fails a worker),
the fact that i'm 2 notches under completely stable suggests it isn't me messing with the pll that's making things work, it's the fact that i'm changing something that makes no difference and it's giving prime a chance to last longer in certain cases
if i run intelburntest and put the vcore down 4-5 notches, i'll bsod with a 101 error, which is too little vcore, but it takes like 7 notches more of vcore to stop bsod'ing 124 in prime blend, what annoys me is my voltage fluctuates quite a lot in cpu-z when i'm priming, isn't LLC meant to eliminate that? i could probably go lower on the voltage if i could stop getting it to go so low for a split second, but nothing helps with it
