I'm thankfully i dont have either issue anymore now, both cpu and gpu is nicely utilised and compliments each other. Did cost an arm and a leg but worth the pennies to get there.
I haven't installed win11 yet haha, win10 just works so far so im not gonna jump on it just yet until i see some limitations in what im using day to day.
I did make a bootable media for win11 just incase, so i have it ready if it does come to it.
4 wats is insane! I think the lowest i've seen mine drop to was around 7w but usually sits around 10w if you average it out.
I've probably picked the worse day for overclocking in 30 degree heat lol but managing a 1.35v for 5ghz Pcore, 4ghz Ecore and 4.1ghz Ring ratio gives me this Cinebench R23 score:
I think i can push the Ecore ratio to 4.1ghz too, i feel there's a tad bit more left in the tank to go. R23 bench does see some high temps though even on a custom loop, touching 94c for the duration at those voltages and vrm temps touching 85c with a noctua fan over it. Obviously gaming temps will be a lot lower so i've definitely hit the ceiling here until i can work out how to do the offsets for core voltage and VID properly.
