Easier than the RAM really.
Standard cooler? Or aftermarket or water?
Set RAM to default speed, CPU multiplier to whatever gives you 4200Mhz, disable Core Boost, add a tiny bit to VCORE, then test.
If all good, try to increase the multiplier a bit more. Once you’ve established a stable clock change you RAM settings back and test again.
Think they pretty much all do 4.2Ghz TBH.
If you rely more on single core performance it’s probably not worth doing though. XFR can boost higher than 4.2Ghz whenever it needs to.
I'm using the Noctua D-14 which did a fine job on my Xeon so will be using and sticking with that.
I've set my SOC voltage to 1.1 and actually found that I had PBO disabled as standard, so enabled that and Cinebench did 1879 multi and 190 single.
The only games I'm currently playing are pube-g, Civ 6, C&C Generals and some other RTS game I forget the name of... no idea if these are heavily single core pegged or not, but noticed Civ boosts all cores to 4.2 and pube runs them all over the place to 4.350 on the majority of cores, but core 1 and 3 were hitting 4.55 and 4.45 respectively.
2700x will pretty much look after itself, i just set my core voltage to 1.35 so it didnt cook itself and set windows power plan to windows balanced(Ryzen Balanced tried to put 1.5v in the chip!) One or two cores will do 4.35 and i get a 4.1 all core boost. I always aim to keep my temps under 65c as over that it loses boost quite dramatically.
I've left voltage on auto, other than SOC as I saw a video earlier from AMD themselves saying any OC or XFR/PBO should have this set to 1.1
Temps I'm seeing around 55-60 gaming but seeing mid 70's on bench tests, but the TIM I'm using is dreadful... so that's getting changed asap!
