overclocking Ryzen 5 5600x with PBO 2 + negative curve optimizer

[mite_jan]

i have been trying to overclock the 5600x for some time now and so far i have best results if i use LLC (load line calibration)
my best cores are no. 3 and 4
i have set the power limits from the motherboard and boost +500 (but it only goes up to +200 probably , some users reported they achieved 5ghz not sure how)
i did lots of testing with LLC on auto but best i could do the curve that way without crashing would be
20.20.5.5.20.20

it came to my mind now to try to use the LLC on an MSI board and i got some interesting results

currently testing 30.30.20.20.30.30 LLC 1
if this doesnt crash i will lower the LLC obviously

my question is is it dangerous to use LLC mode 1 (most aggressive) with -30 negative offset?
also does the scalar setting to 10x does any difference , in my testing i could not find difference

i am with beefy 140mm air cooler (soon plan to go water cooled arctic freezer 2 360mm or 280mm)
temperatures are ok multicore cinebench stays bellow 80 degrees
i am getting single core boost 4850 (because of the locked +200mhz boost probably)
multicore cinebench stays around 4650mhz

any suggestions are appreciated
