So I have a Z370 Asus Prime-A board, an 8600K delidded and custom loop. I just got it together last night and just did a quick OC 5Ghz @1.3V. Thermals are not an issue right now since my custom loop is only cooling the CPU at the moment (420mm + 280mm) since I don't have my GPU in loop for now.

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?

So I've tested at multiple voltages and settings and I've come to the conclusion that, at least on this board, AVX instructions don't want to go higher than 1.264V on the Vcore. So, at least for now, I'm just gonna lock AXV at 4.3GHz max. It's a "new" platform, so maybe there's a bug here which needs to be worked out. Inless someone here has an alternate explanation, I think that's something to note.

What's the weather like in Tampa today? tongue.gif 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).

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.

https://www.pcgamesn.com/asus-tuf-z370-pro-gaming-review-benchmarks
"Asus’ TUF Z370-Pro shows you don’t have to spend big on an Intel Coffee Lake board

Even 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.

Yeah but I'm kinda picking your brains out for your expectations, I guess smile.gif I mean, the X couldn't be more different than the IX, right?

Putting a delidded 8700k under watercooling, with a ambient temp of say 30c

What do you think is the most stable overclock and voltage you could get out of a z370-E/F for 24/7

It's chip dependent & dependent on if you delid since you will hit a thermal wall with the CPU.

Probably 5GHz with an average chip , 5.2-5.3GHz on a good one , with AVX offset. The highest binned i7-8700k sold on Caseking is 5.2GHz right now.

edit: see links in https://www.overclock.net/t/1638955/z370-z390-vrm-discussion-thread/40#post_26380035


Prime Z270-A has a slight difference to STRIX-E/F , but it's minimal due to the mosfet quality
As suspected:
ON-Semi 4C09B+4C06B
