Anyway... is 1.35 to 1.4V too much for daily driver OC on these VRMs if I want to try for 5.2Ghz or so?
What's the weather like in Tampa today?
Looks like 90°F / 32°C ambient...
It's chip dependent as far as power draw. Monitor your VRM temps in Prime95 / OCCT / AIDA64 / Realbench. If it's anything like OC3d's result of 71°C on STRIX-E , you should be golden.
As stated above there's store overclocked bundles with the mid-tier boards pushing 4.8GHz.
If you don't have air conditioning and/or aren't applying airflow to the VRM I would not try to push it too far. You're at the mercy of the VRM heatsink.
Japanese capacitors are rated 105°C 5K or 10K hours (black ones typically 10k or 12K).

Inless someone here has an alternate explanation, I think that's something to note.
Use AVX offset?
AVX increases heat more than normal instructions such as SSE.
I don't think it's a motherboard limitation.

Current draw might be higher. I'd keep an eye on that too.
"Asus’ TUF Z370-Pro shows you don’t have to spend big on an Intel Coffee Lake boardEven though it’s got that pretty limited six-phase power design our board was still able to push the Core i7 8700K up to a heady, stable 5.2GHz.
" - wrong info to give to people.
Why is this wrong info?
A. The $160 board is as expensive as a half decent one , while having a horrific ALC887
B. You can reach 5.2GHz on a board as a suicide run, but unless it is stable and tested under stress it's not a true 24/7 overclock.
C. No word on VRM temperatures or any CPU / VRM throttling
D. Asus doesn't know it's doing with the TUF Lineup whatsoever, it's been shuffled from high-end to mid-range and now we have cheapo "gaming" boards with the TUF 5 year warranty. It's a TUF board with 5K rated caps albeit 5 year warranty. Plus aesthetically nothing goes with burnt yellow.
*** If ASUS put a decent VRM from the Z370-A on this , added 10K hr rated caps , blackwing chokes, put a monster heatsink on the VRM with a heatpipe on it , then maybe it would be worthy of the name. Or better yet, if it used TI NexFETs.
*** The M.2 SSD slots don't have any thermal dissipation to them
*** no backplate
E. all of the above
More false advertising maybe?:
In other news, 5.5GHz on the Fatal1ty K6 on i5...

The money was spent on things like Debug LED + audio amp.

It's chip dependent but Asrock's Fatal1ty K6 or Extreme4 are good bets.

Until shown differently, I would say the $160ish Z370 Fatal1ty K6. Except for the audio result (I'm not sure why hardware.info got a better result for the Extreme4 without the TI amp in terms of dynamic range) , everything else is roughly on par with a Maximus X Hero.
