Right now i could only get 4.9ghz with no avx offset, cache 48 get pretty decent bench results. 5ghz with this boards seems to not be possible. Tried all sorts of vcore, cache speeds, AVX offset...no luck. I could post and run benchmarks, play games but cant pas realbench.
I was considering 9900K, but, besides the extra cost, i am worried about those temps.
With 8700K @ 5ghz 1.34v, its dellided, but on noctua dH15 i managed to max 75c on realbench on a day with 32c ambient on my room, so 43c delta. 8700k rocks like a champion, on colder days like today i run it around 65c its really awesome.
I know the thing is you want to run it fully under 5ghz, but there are options:
a) Use some 360mm AIO, but with loudy fans
b) Consider lowering it to 4.8ghz. As far as i checked around, its a sweet spot between frequency x voltage x temps
c) direct mount
d) lapping the die
AFAIK, part of the issues are due to the bigger diffusion barrier that intel increased to deal with the solder.
