AMD Ryzen voltage control settings

[LAMSTER69]

Hi Guys,

 

I have overclocked a Ryzen 7 CPU to 3.9Ghz @1.4V.

 

I have done a lot of OC'ing on intel and there is a adaptive settings where it only uses the overclock voltage when it needs and otherwise dials down the voltage.

 

Is there a settings for AMD that is similar to this. As of now it is pinned at that voltage regardless of the clock (AMD cool 'n' Quiet is enabled).

 

Motherboard is MSI B350M Bazooka

 

All feedback/advice is grealty appreciatred

Ryzen 7 8core at 1.4V with that trashy MSI motherboard? The VRMs are baking themselves and if the total garbage highside overheats and fails, it will fry your CPU.

What you need is AMD ryzen balanced power plan, which is included in their raidxpert software. Install that and then change power plan settings to it, this allows the CPU to lower frequency and voltage when not needed.

The mobo will explode before he manages to do that lol

Well, his choice...  I don't know about the VRMs on that board, but you could be right. I'm only running mine at 1.32Vcore at 3.85 on my 1700 with my ASrock Ab350M, made sure I got a board with half decent VRMs, this was only supposed to be a filler board for me until a good itx x370 board came out (bought fairly early on), but am so impressed with the features and abilities of this one that I decided to stick with it.

I don't think 1.4V is too bad, but as you say it depends on the VRMs and cooling thereof... Most VRMs IIRC can handle 125-150C with ease, but if they're not being cooled adequately then it's not going to take much to reach unsafe temps... that's about as much as I know about VRMs (or think I remember about them anyway)

The MSI mobos are junk.

Asus will release ITX in october, you could get those becase they will certainly have better VRM than your ASRock.

Also, at the temps on the mobos (as OP has) with that voltage and R7 are so high they will blow up the caps.

The ASRock has huge drawback not having Digital voltage controller (isnt able to set things from BIOS like LLC).

Temperature over 100°C is always concerning and with the latest thermal data i saw from mobo with similiar trash VRM but R5 1600 at 1.4V (!!), these will run at 110 minimaly.

What will be better about the ASUS boards VRM then?

Every ITX on AM4 has good VRMs except Biostar.

The ASRock B350 and X370, even the Gigabyte mITX.

Asus has usually nice parts, i would wait.

Asus has also good memory support and better BIOS than ASRock

Sorry but that doesn't really answer the question. You said that the Asus board that's coming out would have better VRMs than my Asrock board has, better in what way?

Stronger and much more efficient components.

Your mobo is not optimal for R7 overclocking, i would stay at stock tbh.

The mobo you have is the middle of B350 VRM quality.

You dont have to wait and grab one of the ASRocks.

Sorry, but you don't seem to know what you're talking about. Have had a very good OC on this board before, the only reason I am only OCed to 3.85 on this board right now is because I don't have a better CPU cooler. To suggest I stay at stock is ridiculous in the extreme. Even a board with crappy VRMs would manage a mid-OC with no problems.

VRM temps?

The VRMs are not that bad to influence the overclock quality, but it cuts off their lifespan

With stock cooler it will be fine

TLDR

using stock cooler - fine

having airflow over the vrm - fine

is it optimal - not really

He literally does this quite a bit.  Seems to enjoy showing up in other people's threads and either mocking their build or shitting on their motherboards.  I would take anything said as just good humor.  

 

I'm a big fan of all the sensationalized talk of explosions and self-destruction.

I mean, who wants to blow up the mobo

Agreed and I sure don't.  The unfortunate thing is there'e very little failure data to support this happening in the definite way that you imply.    

 

The fact that you are actively posting in these threads indicates that you want to help and that's great.  A little less of the "Sky's falling" stuff and I'm sure people will appreciate the advice more.

I don't recommend running a Ryzen 7 higher than 1.35v unless you are just trying to benchmark.

 

AMD recommends a 1.35v MAX on Ryzen 7 if you want longevity, with a 1.45v being the maximum safe voltage, but not for everyday usage.

 

I would suggest lowering to 1.35v and testing for stability, and even go lower if possible.

 

I personally just use Ryzen Master and enable my OC when I am doing CPU heavy tasks where I need the jolt.

It is usually hard to explain people, you sure know the stuff, no need to explain it to you.

Lets take an example.

I see in builds B350 Tomahawk everyday, i tell people "dont get it, it is garbage and not worth your money"

They fire back with a video of usually a guy on youtube, who has lets say 1000 subscribers and shows how brave he is when he puts R7 on the Tomahawk and amazingly overclocks it to 4GHz at 1.4V.

He doesnt mention that the VRMs got over 100°C, he usually doesnt even know that, but that is the problem with that part of the community.

They usually dont know that highside turns off, charges the choke, then turns off, then lowside turns on to mantain the voltage and current flow, then it goes through main capacitor bank and to the CPU.

The problem with some of the B350s is that they put excessive load on the highside array, mobo manafacturers nowadays dont know how to make a heatsink and you have one hell of a hot potato.

Thats why i always freak out, because people try to convince me that their overclock works and is stable. OK, thats good, no problem, but what about the VRM temps?

Would you risk frying your CPU? That chance is very small but exists

OP of this post exposes himself to chance of the VRM failure because the is pulling significantly more than is healthy for the VRM.

I'll ahve you know, on OCCT for 15 minutes no higher than 70C and AIDA 64 for 36 hours no more than 50C.???????

Is it the VRM temp sensor?

I highly doubt it even exists on that mobo.

Here is a screen shot of HW monitor while the AIDA64 stress test was running. I leave it to you to let me know.

 

So is there a concerete answer? I am getting suggestions which seems to raise debates.

Also if I may add

 

OCCT at 1.38 V @ 3.9GHz I got a blue screen

No VRM sensor.

Do you have IR thermometer?

Also, which cooler do you use and how big airflow

There is no VRM temperature sensor on the board.

Touch the heatsink while Aida64 stress after 20 minutes.

It is the worst possible scenario for VRM cooling and lifespan you got there

??? I am confused, please explain

 

and what heatsink? the CPU cooler?

 

The CPU cooler is warm on touch, no uncomfortable feeling at all whatsoever

 

You are worrying me now, a lot.
