Agreed! I finally found the source of all my ails: putting the clock speed on anything past 4.275. Doing this speed + 2933mhz DRAM overclock allowed me to finally run Cinebench however many times I needed to do so. This allowed me to finally try different settings and pull samplings from Cinebench (running 5 times).
So using this, I was able to settle on vCore 1.37. I do have this on LLC1 which yields 1.38 under load.
Cinebench scores are 1948-1952 which is what I was angling around.
Also good news is that I was able to drop down to 1.35 vCore no problem @ 4.275 clock speed, but this yielded 1930 scores.
So now I will ruminate/research a little more to find out if the extra voltage is worth it. It's more of a psychological thing at this point.
Oh, I should also mention that I was able to bump up my DRAM to 3000, and with the Ryzen Calculator get the timings down to: 14-16-14-17-28. SoC is at .9875.
Running MemTest now to make sure the memory is OK with this. Then I will look into Prime95.
EDIT: Attaching my Ryzen Calculator Memory profile for more context.
