So, I believe that my 5950x with CO and with SMT off does not require more than 180A (I am not sure about this value, but I think something similar), so I suppose my 8 phases heat less than half of the example you provided, correct me if I am wrong.

Use CPU TDC, CPU EDC and CPU PPT, TDC stands for sustained current, EDC for burst current and TDC for sustained power.

To make sure of that, could you tell me what is the correct value to look at on hwinfo for vrm temperatures? This is the first motherboard I am having trouble finding them with. I'm assuming they are "Ciclo VR 1" or "Ciclo VR 2" values (sorry for italian language used in hwinfo, anyway Ciclo means Loop).

Use Circlo VR 1 from the controller (ISL69138) with the larger corrente (IOUT) value. Seems like your board has two of these, one handles the core power and the other SOC power. Both Circlo VR 1 are technically important but core power should be the one that runs hotter at all times. Except when you use APUs that is.

I double checked my PBO limits cause i didn't remember anymore and i have PPT 200, TDC 200, EDC 150. What do you think about it?

And what about vrm's temps reported in screenshot (50°C max)? Should i worry about it?

TDC is meaningless to be over EDC.

 

The maximum temperature only means something when you stress test the CPU to make it burn as much power as possible and put the VRM under maximum load.

What software do you recommend in order to put cpu/vrm under maximum load?
Anyway. thanks for advice, I'll change TDC/EDC, you're absolutely right.

I'd recommend Prime95. It has multiple presets like blend, smallFFT, largeFFT etc, you'll have to test and see which one makes the system draw more power.

Here is Tier A: B550 TUF Plus (mATX & mATX WiFi)

But I can't find anywhere mAtx version. There are only B550M models that are rated to Tier E/F.

 

Can you send me link to matx version of B550 TUF Plus?

B550M just means they are B550 mATX, the chipset is the same so I do not use the B550M name. Same holds true for mITX (B550I) or other chipsets.

those are not the TUF B550 boards.

I ran the SmallestFFTs, SmallFFTs, LargeFFTs tests for one hour each, and finally the Blend test for 2 hours. Passed all with no errors and no warnings.
The worst in terms of VRM temperatures was the LargeFFTs.

In any case, I never exceeded 56° peak on the VRMs, reported in the "Maximum" column of HWinfo.

I suppose it is also due to the airflow of my case (LianLi O11D XL, full of fans).

Can I therefore be comfortable with these temperatures?

it's fine to hit mid 80s even.

I would like to know how Biostar Z590 Valkyrie LGA1200 fairs in the ranking.

 

From what I've read it has specifically been praised for the VRMs. Even has separate VRM fans built into the motherboard. I read on overclockers they were rated at 90A... 

 

Apparently the Valkyrie beat the Z590 version of Phantom Gaming by 12°C and Valkyrie also beat the Aorus Master by 30°C

I dont have any Z590 here, but even if I were to make that list it would just be up top in the same tier as all the other flagships. Overkill is overkill, 50% more overkill doesn't get any more points.

B650 and X670 when?

[marinska]

Hello there, I need a little help changing my motherboard, this is my second time building a pc and I learned a lot of things from my first build, so I'm trying not to make the same mistakes. i currently have r3 3200g + a lousy msi b450m pro m2 v2, straight up in F tier lolo

 

I plan on building an r5 5600 + 3060ti which I hope lasts longer for 5 years or so as this might be my last upgrade for socket am4.

 

There is a used asrock x570 phantom gaming 4 for 86$ and a msi b550-a pro for 125$ near me, is it worth to choose that cheap x570 or should get that b550 instead? (a new b550-a pro is 160$ here xd) OR should I go for the new asrock b550m pro4 for 110$ considering I don't overclock most of the time (although I might try it a few years later if I really need more performance).

 

Btw i'm using a montech air 1000 lite case and a deepcool gammax 400 cpucooler, modifying it to 2 fans for push and pull, also 3x front intake fans, 2x top intake fans, and 1x rear exhaust fan

 

thanks in advance

B550-A Pro used looks to be the best choice but ofc everything about buying used applies.

It was used once for testing and bios update tho he bought it at feb 2021

Since it has 3 years warranty until feb 2024 so it still has about a year and few month warranty left

Is there a sort of beginner's guide to interpreting this information? I get that the boards are being rated by how much power they can supply before running into issues, but to me it's not clear if this is:

1. Directly to the CPU
2. Board as a whole, incl Audio and WiFi devices, SATA controllers, &tc.

I'm also trying to understand how to evaluate if/when this is relevant to my use case. How do I use this data to ballpark if a board can handle the CPU that I'm considering/when should I insist on going up a tier?

 

Sorry if this is really basic to the regulars. I've looked around a bit, and haven't figured it out.

Directly to CPU. The rest arent handled by the main VRM which is the point of focus. You couldn't really push those beyond sustainable limits.

 

I made the list conservative enough that you shouldnt need to go up a tier.

[sailsman63]

@Jurrunio Thanks. And I finally realized that the list actually simplifies it down to TWP of the processor - I was trying to work backwards from raw amperage numbers, and AMD doesn't seem to list anything other than TWP - I even had to look up what typical operating voltages look like.

Hi guys.

 

My pc keep crashing i think because processor overheat after upgrade from ryzen 5 3600 when playing game either it high or low but when i undervolt my cpu 1.2v and speed 4500mhz. Its work and the processor temp between 60°-66° when playing game. Is it my motherboard the problem?

 

I dont mind undervolt my processor but is it safe or i need to change my motherboard?

 

My spec:

-Amd 5 5600x

-Ram gskill trident z neo 16gb 3600mhz

-Palit gaming pro rtx 3070 8gb

-Mobo ASRock b450m steel legend

-seasonic focusgold 850w

-2k monitor

 

Note:sorry my english is bad

is the bios the latest version? Sounds like the stock settings arent set properly.

 

Even if there's a problem it's not a hardware one, so you dont need to change the motherboard. Undervolts are safe though you should run some benchmarks to check for performance loss

Yes my bios already latest stable one well there a beta bios and bios for rtx 4090 compability but i dont think i need that one.

 

Or is that my cooler i test using amd stock cooler it 50°+ on idle even when undervolt and its still crash.

 

Im using deepcool game max l120 v2 when idle temp 45° normal and undervolt its between 39-42.

 

If i recall I lose 3 - 7 fps in cyberpunk 2077 and somegame but i dont don't mind aslong its 60 fps. I already try RMA my processor but they say its not processor but alot people have this problem and undervolt always work for them

Honestly I'm suspecting not enough voltage at stock... Undervolt can cause crashes if done too much and results with different coolers are not comparable because lower temperature increases stability (to a certain point).

I dont mind for now but on certain point if i need to fix this permanent do you have sugestion to do?

Oh some update as u suspect when i add more volt and keep the speed it still crashing even tho the temp still 60°
