(Quality of mobo, Gigabyte (4+3 with onsemi) > Asus (4+2 with onsemi) > Biostar (4+3 with sinosem) > MSI (4+2 with nicosem) > ASROCK (3+3 with nicosem, commonly better VRM give u better temp and stability when OC under high volt, still not recommended for OC 24/7 under 1.4v with ryzen 7 + B350 mobo, commonly give u about 100'c on vrm, got possibility toast ur mobo after long time run.)

I'm quite sure the Asus VRM uses better mosfets that are more efficient than Gigabyte which is using mediocre/low end mosfets, similar in quality with MSI in their B350 mb's. Asrock may only have 3 power phases for the cpu but it doubled up all the components so the VRM will probably run alot cooler which is important since heat seems to be an issue for 6/8 core builds.

which asus board, can be specific?

I was talking about b350 mb's and there are only 2 of them at this time.

There is some youtube and review that oledi confirm of vrm, but not every model. Below is the vrm of mobo which confirmed. Asrock only 3 power phase but not doubler. Current B350 range which confirmed vrm easily hit 100'c on 4+2/3 vrm with heatsink applied when run under 1.4v for oc, but still in safe range. Gigabyte AB350 Gaming 3 and Asus B350 plus both using onsemi mosfet.

B350 mobo range
MSI B350 Gaming Pro Carbon (4x2+2 nikosemi,unconfirmed) > Gigabyte AB350 Gaming 3 (4+3 onsemi) > Asus Prime B-350 Plus (4+2 onsemi) > Biostar B350GT3 (4+3 sinosemi) > MSI B350M Tomahawk~Mortar Arctic (4+2 nikosemi)
> Asrock AB350(M) Pro4(3(X2)+3 nikosemi) = Asrock AB350M-HDV (4+3 nikosemi,unconfirmed) > MSI B350M Gaming Pro (3+2 nikosemi)

You don't understand what I said, see the video which was posted earlier by hairy.
Asus mosfets are better quality and so the VRMs will run cooler than 4+3 Gigabyte. The soc side VRM doesn't have to supply much power so it is relatively unimportant.
Asrock has 6 phases for the cpu side VRM, theres more than 1 method of doubling. The cpu side VRM will run cooler because theres more components to deliver the power.
According to the this german review,
"They run all quite hot, the gigabyte B350 Gaming is the worst, over 110 degrees with a 1800X stock. Biostar up to 100, Asrock over 80. Best ist the Asus B350 with under 80"

Users are reporting >110C ~1.3-1.4V with Gigabyte. 110C might still be within spec but thats not good since there are other nearby components which will be affected badly by high heat. Typically motherboards will throttle or shutdown at around 125C for VRMs.

I'm know that soc side didnt consume much for ryzen, its necessarily only for next gen apu. I replied with stated both using onsemi mosfet, didnt talk bout 3 or 2 phase of soc, just fyi, gigabyte not really using a lower end mosfet.

From pic which confirmed revealed i googled, Gigabyte and asus using similar onsemi mosfet, asus using  4C09B+2x 4C06B, and gigabyte using  4C10N+2x 4C06N. But maybe there is batch of mobo using lower quality mosfet, and both mobo using different power phase controller, so is it will impact temp? i m not sure, because i'm found temp imaging in tweaktown for x370 range onli.

Accordinng to bullzoder, Asrock does using 6 inductor, but it actually only run in 3 power phase, no doubler, the temp is lower maybe due to 2 inductor per phase. But its only 3 phase.

Anyway, if u need better lifespan, B350 not a really good choice for long run load with high OC, this is the reason i m not recommend B350 range mobo for heavy oc user. From llk experience with his asrock X370 k4 which is lower tier X370 range with 4x2 power phase, exceed 70'c under 1.3v oc.
In the fact, if heavy oc, its not hard to expect around 100 or more than 100 for temp with B350 range mobo.

P/S: stock of ryzen always not really efficiency of volt when heavy load than oc.

It should be quite obvious we are talking about current Ryzen cpus not apus.

You're incorrect, the previous video by buildzoid clearly says that the Asus has better mosfets and what he says is backed up by multiple reviews show the same model numbers so there is no dispute there. The Asus uses the 4c09b which has a better rating than the Gigabyte 4c10n for the high side mosfet. The low side have the same rating for both brands. I've already provided a link which showed a good review showing significant differences in temps. And many users have reported similar high temps.

You clearly missed the part in the video which shows that the Asrock has double the number of high side mosfets of Gigabyte and not just the inductors which will help bring the heat down. Asrock doesn't have a real 9 phase design but the components in the VRM power stages are 9 phase.

The point is not about long term heavy overclocking but your clumsy motherboard rating based on the number of phases.

I used the numbers given by the stock 1800x since if a motherboard cannot handle stock clocks, it will not overclock properly at all.

From HWMonitor, which temp is the VRM reading?

It can be hard to tell. But you can try comparing the various temps when the pc is idle then run prime95 and see which temps shoot up. Then aim a small fan at the vrms and see which temps go down. You can then make a good guess.
