On my decision i got a ASRock Z390 Extreme 4 and i loving it. It is one of the best cost/performance ratio in my opinion.

U can get a decent UEFI overclocking settings (same as the Gaming x) VRMs and an absolute nice vrm cooling and this for around 170 bugs.

What do you have the processor overclocked to on the ASRock Z390 Extreme 4?

I would like to know if this applies to the other z390, @AlphaC .

Don't have much to add to the conversation other than my Taichi is handling my 9900K very well, no complaints with it. At MSRP (~$230) I'd go for the Ultimate for not that much more, but it often goes for around ~$180 and IMO it's a steal for the price.

Intel i9 9900K Coffee Lake @ X8 5309mhz (+47.5%)
AMD FX-8320 Vishera @ X4 5022mhz (+43.5%)
Intel i5 4690K Haswell @ X4 5013mhz (+43.2%)
AMD X4 960T Zosma @ X6 4870mhz (+62.3%)
Intel i7 6700 Skylake @ X4 4709mhz (+38.5%)
Intel i5 6400 Skylake @ X4 4588mhz (+69.9%)

Guys! I'm glad to read someone's having good experiences with the z390 Asrock's. I got my Extreme 4 for my current build but its behaving like total crap. I've had great experiences before with my 8700k but this one is not cutting it.
First on the Extreme 4 at least, LLC (on vcore offset mode) wont give me the full 1-6 settings, i could use 3-5 ***. Now if i use fixed vcore, then i get 1-5 iirc.

The vcore seems to be a hot mess, meaning it doesnt stay still much. Different application draw different vcores with the same settings yes.
Using Linx64 i get 1.34vcore during AVX test with a -15mv offset setting in bios. The same settings yield 1.36 spikes using Realbench. What are you experiences. What settings are you finding best?

Really appreciate your feedback as i dont want to go nuts and just buy another board. Don't really want to deal with the down time of RMA or return.

The more limited LLC settings when running full auto or adaptive confused me too, but as it turns out it was not an issue for me. I'm overclocking my i7-9700k to 5.1 very happily on adaptive and did not need to touch the LLC at all. The board is doing the right thing. I have Z390 Taichi, but it's the same OC options you describe.

Do you mean that vcore won't stay constant in "fixed" mode? In adaptive or auto, it is designed to fluctuate with load. The processor has VID which tells the motherboard how much voltage it would like at any given moment.

You describe using a -15mv offset which sounds like you're using the adaptive mode. The voltage SHOULD fluctuate according to load as the processor asks for more of less voltage from the motherboard. That will vary with instruction set too as AVX instructions need more power. I've found offset mode to be the best mode for overclocking the CPU on my Taichi. FYI, the VRVout voltage is the better one to look for in HWiNFO64 (if your Extreme4 has that) as it's a better measure of the actual voltage going to the CPU (measured closer to the cores themselves).

You're looking at VR VOUT and not VID, right?

Thanks before all.

For the Extreme4 there's only offset or fixed. On fixed, the vcore does remain steady, or at least i don't recall having an issue with it. In offset, i do know its suppose to bounce around depending of the cpu state but i meant the instability under stress testing where cpu speed is constant and so should vcore.

I've read about the VRVout else where but once more lol my board doesn't have it lol. I've tried so find it, not voltage date at least on HWinfo64 with that name, where's yours?

I'm going to try leaving the LLC on auto which i think it uses 4 and see what i get. Im using Linx64 so it uses AVX(Realbench does as well), i know that when AVX hits ,my vcore shoots up a bit. I may try also an AVX offset to try an keep the vcore from jumping compared to non AVX state.

Where exactly is this VRVout, i dont have that with my Extreme4
Ill upload a screen of my hwinfo when i get home.

Just because CPU speed stays constant does not mean that load is constant or that the vcore should be constant when in offset mode.

Watch the values of VID for each core. That's the processor telling your motherboard how much voltage it wants. Those are not constant when I watch them during a stress test.

As those vary, the processor is telling the motherboard to vary the voltage it gives the CPU. Perhaps this varying VID is more pronounced in this generation than what you've previously overclocked with?

In the end, what you should care about is system stability, not how constant the VCORE voltage is. In fact, you want the motherboard to lower the voltage the moment it can (even if just a little bit and even while still at full speed) because that creates less heat and makes for lower temperatures.

I can't tell you exactly where VRVout was for me because I've rearranged the rows since in HWiNFO64. I think it was about 2/3 of the way down when scrolling. But, it is present only in some boards.
