Hey guys I just wanted to give everyone the VRM types and motherboard power delivery specs for the major players. Often people like to know these kinds of things Ive compiled a list if them together from various sources. It should help in any decisions… for OC boards and what not. However to be honest there are many reasons to have good power delivery.

I for one wish these were more public. Its a darn shame that people who work for the manufacturers or even the hacks who O.C do not share this information and when you ask most do not share as if its some kind of secret. Perhaps it is and I am not in the know but here are all the ones I know and Im sharing it with all… I appreciate the crowdsourcing of errors and confirming the unknown or blank spots… :slight_smile:

Let us start with the better quality boards and companies and go in descending order. I am determining quality based on the last 3-4 years of QA, the quality of UEFI, the quality of UEFI updates and supporting new chips, and the quality of the features and power delivery onboard. Right before we start I will list the power stages companies and what the model numbers say.

List of Companies
IR= Infineon Technologies
ASP= Proprietized ASUS customized version of IR35201
uPI= uPI Semiconductor
TDA= Infineon Technologies
QA= Offshoot of uPI
SIC= Vishay Semiconductor
S4= OnSemiconductor
ISL=Intersil

Let’s begin with ASrock the best company as of late.

Now we have ASUS. Great EFI not the best quality control as of late. A lot of features most of which you do not need and well they are damn sexy boards I will give them that.

Finally we have MSI. While some boards are good others are hit or miss. Particularly their mid tier. Nobody expects the low tier boards to perform anyways but the mid tier that slots into budget points the QA has been horrible for years. Quite frankly they have repeatedly tried to work on it but they are still havent figure it out. Im not quite sure why and I open to discussion about whats causing it. Their EFI looks amazing. They work close with AMD spec to provide the most tweakable options and they have decent looking boards…

What are VRMs?

Want to know more about power delivery check out this post: VRMs - The what, why and how they operate!

Why is this important with X570?

You might ask does power delivery matter if AMD Ryzen chips are so power efficient… The answer is yes and that is because of a phenomenon that occurs with smaller and smaller node processes… Voltages can no longer be as high as they used to be… Period said done… The chips cant just be driven to a stable O…C anymore by pumping voltage… We are seeing a lot of motherboards blow the new ryzen chips over this because auto control is spiking voltages far above the 1…325 safe recommended limit and above the 1…35 V damaging limit threshold… The reason it blows these chips is because Electromigration… The high-speed electrons that flow through the wire occasionally bump into the copper ions causing a momentum transfer, gradually skewing them in a certain direction… Using a pipe analogy, the metal density at one end decreases and piles up on the other end… The decreased density, or void, affects the reliability of the integrated circuit which eventually results in a failure due to the increased resistance and to mitigate the problem and protect the wires, manufacturers introduced diffusion barriers and liners using other materials such as silicon/tantalum nitride and oxynitride… The barrier is used to to prevent metal diffusion into the dielectric while the liner is used as “glue” for the barrier and the copper… Once those are in place, the copper seed layer (metal plating) and then the bulk copper is added… This worked nicely, but there is a problem… As interconnect continued to shrink, the thickness of the high-resistivity liner/barrier for the copper interconnects stayed more or less the same… This is largely due to the difficulty in thinning it any further than the few nanometers it already is… This means that as the wires scale, the barrier itself takes up a larger and larger portion of the interconnect cross-sectional area… With the high-resistivity barriers slowly making up a larger portion of interconnect, it begins to dominate the resistivity of the wire itself… This isn’t the only issue affecting the wire scaling… The mean free path is the average distance the electron travels between collisions… Since the mean free path λ for copper is almost 40nm, then as the copper interconnect approach λ or 40nm, the copper electrons will begin to scatter far more often from the various surfaces and grain boundaries because they are so area-constrained… This excess scattering increases the resistivity of copper… In turn this also plays an effect with self heating which is an issue below 14 nm no matter how you slice the sand…

The OMG its at 1.4+ Volts on board xyz Fix (Temporary)

The fix to those MOBO’s before the new EFI is available: Disable CBS or core performance boost… completely… then go to full manual control… voltage control and make sure you have set all the voltages not just one and left the rest on auto as that according to the internet crowd source is causing stability issues. If you do so and remain under 1.325 V you have zero risk of blowing up a chip like hardware unboxed did RIP their ryzen chip it was an honest mistake. As great as all this new tech and engineering is… it is important that people understand its limitations.

So I hope this information helps some people. It kind of veered off topic for a bit.

  • ASP1405 is indeed a customized version of the IR35201.
  • ASP1106 i think is an ISL controller, likely a ISL95712 / ISL95866 or similar.
    I don’t think that it is an IR controller.

Good note I’ll look into it. If I can find a picture of that board and the controller and look at it’s pin out

@Heimdallr

Would you mind mentioning the memory topology is used on all boards.
As far as you can find of course.
Asus is using Daisy chain memory topology on their X570 line of boards.
So those should generally work well with a wider variety of kits.
And i believe Msi as well, but i have not looked closely to Msi’s X570 memory topology yet.

But Asrock is using T topology on certain boards like the Asrock X570 Phantom Gaming X,
and the X570 Taichi, which will means it will be finicky with memory kits and overclocking.

This might be an interesting item for @wendell as well to look at,
when doing mobo reviews, and memory kit testings. :slight_smile:

According to Buildzoid, it is a real 14 phase without any doublers:

I could try I will have to analyze traces for each with high res pictures of Rev 1.0+ Not sub 1.0 of motherboards. I could use help little lady :wink:

LOL build zoid says you cant analyze trace quality eyeballing… Yes and no… See with image enhancement you can follow them and super impose stuff to see where they go and analyze trace width and route length ahah

This is the first time I see claims of blown Ryzen chips . Care to elaborate a bit more (percentages , does it happen only on x570 motherboards or on x470 also , etc) ?
Is it maybe an indication that the new nod might be a limiting factor for the cpu’s life span (taking into account the possible aggressiveness of frequency boost in order to be competitive against intel) ?

It’s actually more common than you think right now.

@Ancient_Evil_God has a story he may like to share about how his board pumped 1.5 volts on boot…

Hardware unboxed blew there’s… etc

There are a lot of account out there

Yea with public bios I was getting 1.5volts on idle and full load. I got my hands on a better bios. Full load now doesn’t exceed 1.35volts. The public bios for Crosshair VIII Hero Wifi is complete and utter trash at the moment. I had to disable core performance boost (the thing that would allow for all turbo clocks to 4.2ghz and single core to 4.6ghz) It is not precision boost overdrive. With the public bios I was getting 95c easily and shutdowns were happening.

I can say with certainty, I am running between 65c and 70c on 100% handbrake load now. Mobo partners need to get this fixed, or AMD will be replacing a bunch of cpus.

Damn, do you know of any other manufacturers afflicted? (I own a X370 Taichi and I’m curious in that regard)

The ASRock taichi has always had solid UEFI’s honestly testing will be the definitive answer

I doubt the taichi is as crazy about CBS and pbo right now

T topology is better for overclocking 4 dimms, Daisy chain gets higher and more stable overclocks but only with 2 dimms.

I would say Ryzen should try to move towards daisy chain…

and threadripper should stay T but honestly… we are splitting hairs at these levels for the average user. Im all up to identifying the topology with some aide and making a library of info on these

Asus hadn’t even updated the listings for what motherboards supported the 8 cor and 12 core chips until Friday. I tried to get some assistance troubleshooting a 3900x memory issue on an Asus x470 prime pro on Tuesday and was told that they don’t support the 3900x yet. I think its going to take time to get stable Bios on the non x570 boards.

Wow, yet another blunder from them. Honestly I do not know whats up with them lately. Like they hard core have just sucked even when ryzen came out they still were hard core making better boards for intel and its bothersome but it doesnt matter. A stable bios from some inside sources is about to be released with ASrock… they seem to be working very close with AMD… which is good to see

Seriously I would not harp on them without reason… Come on ASUS step it up a tad even BuildZoid is calling you out
