I am stable at 6800 and 14900k. T create.

Stock is 253 watts and no power limits my cpu pulled 340+ watts. I was able to avoid thermal throttling with a 360 mm aio with a 320 watt limit for both.

Fellow ASUS mobo here.

Set “aitweaker->asus multicore enhancement” to remove all limits, drop the long and short duration package power limits in “aitweaker->internal cpu power management->” (you can do this in intel XTU too) until you are no longer thermal throttling for more than 1-2 seconds (mine is set to 320 watts for both). I didn’t use any LL or undervolting because my chip would become unstable right away. Went from 37000-39000 to 41000 and pcore temps in the low to mid 90s.

Proart Z790 I purchased recently

I have a thermalright contact frame in mine, no issues.
