Motherboard VRM Tier List v2 (currently AMD only)

Im getting a third m.2 for free by my brother and im thinking of switching my MSI MPG X570 GAMING PLUS with GigabyteB550 Aorus Master or ASROCK X570 Taichi, is there a difference between these 2 regarding quality and vrm performance that i should think of?

 

As long as they support AM4 (5900x this being my case) and 3x m2 slots it should be good.. And these looks like the ones that are avaible in norway right now.

 

edit: this is my 1200 post, woo.

Being X570 the two M.2 slots not connected directly to the CPU's PCIe lanes would have more combined bandwidth than B550. If he's not an overclocker Asrock would be fine, but if he is then Asrock tends to do worse there.

This is actually for my PC haha, but I don't care about overclocking anymore.

 

Ill see to the B550

If I'm understanding this right, the B550-XE would be on the same tier as the Crosshair VIII Dark Hero right? Considering they both have the same VRM (14+2 phases with 90a power stages)

preferably, 105w stock TDP is still too much for this board so you'll have to slow the CPU down further.

Like underclock and undervolt?

Love you all!

Is there currently a plan to begin an Intel boards list?

[AquaVixen]

So I found this today and I own an MSI X570 Prestige Creation. I was under the impression from multiple review websites and youtube reviews that this was one of the best motherboards VRM wise. I was thinking of buying a ryzen 5950X for it this fall and of course I plan to overclock it too. I do some video encoding and transcoding fairly often and I'm concerned with thermals over long (24-48 hour) render times. I have software that fully utilizes both the cpu and GPU for this task so I'm concerned about the CPU. Your list has it red/orange for the top of the list in the S tier. Are you trying to say my board isn't good enough for an OC'd 5950X? Or it just barely is? Will it struggle with this CPU and run the VRM's hot? Should I not buy this CPU and use it in this board?

I would recommend this list https://docs.google.com/spreadsheets/u/0/d/1wmsTYK9Z3-jUX5LGRoFnsZYZiW1pfiDZnKCjaXyzd1o/htmlview#gid=2112472504

Yours seems to be Tier A

And how about a 5700X ???

So it's probably safe for an OC'd 5950X then? I want this setup to last me at least another 4 years maybe 5. I want to wait until near the end of AM5 before upgrading again.

Currently too busy. But what I can say is Z690 has few bad ATX boards, just dont get MSI or Asrock ones below $180 if you're using a 12900k. mATX boards and B660/H670 boards are more troublesome due to lack of info, but this

pretty much sums it up for how high in the product echelon from each brand to start looking.

It's barely enough by liquid nitrogen overclocking standards, for normal watercooling it's more than enough as long as there is case airflow.

it's fine at stock. You can see comparisons between 5700x and 5800x that they aren't that far in performance, kinda why you shouldnt get higher TDP parts when they are all unlocked. As for the 5800x3d, it will be faster (but less than what reviews show) than the 5700x when you limit both to 5700x's power levels but 5800x3d is ~50% more expensive, making it worse value.

I'm using the MSI B550 Tomahawk and it seems to be stable at -0.3v (switching frequency 900KHz)
If the switching frequency is lowered, an error will occur in OCCT
For undervoltage, VRM response seems to be important.

 

CPU: Ryzen 9 5900X
M/B: B550 Tomahawk
MEM: Ballistix Sports LT DDR4-3000 CL15 16GBx2 @DDR4-3200

vCore offset: -0.3v

VRM Switching Frequency: 900KHz LLC1

Precision Boost Overdrive: [Advanced]

 PBO Limits: [Disabled]

 Precision Boost Overdrive Scaler: [Manual] / [1X]

 CPU Boost Clock Override: [Enabled (Negative)] / [-450MHz]

 Curve Optimizer: 3/3/3/3/3/3/5/5/5/5/5/5 (Positive)

Since this is downclocking + Underbolt, the benchmark score will drop.
However, since the purpose is silence, only stability is confirmed.

Did you verify with benchmark scores before and after the undervolt?

Hello, I'm actually currently looking for a motherboard and I was wondering what the best motherboard for a 5900x would be...now it states above that the aorus elite is in the list for that tier at ambient cooling, but the pro doesn't? Also the tomahawk x570 or b550 isn't even on there. Does that mean it was too hot compared to the mortar?

Are we looking in the same place? Sorry if I misunderstood.

 

[bkrenderman]

Tier C :125A current draw on little ambient airflow, maxed out 2700, 3900x and 5900X at 1.2V on ambient cooling (P95)

Asus: X370 Prime Pro

Asrock: B550 Pro4 (ATX & mATX), Phantom 4

Gigabyte: X570 UD, Gaming X, B550 Aorus Pro (mATX), Gaming X, X370 Gaming K7, Gaming 5

MSI: X570 Gaming Pro Carbon, B550 Pro-VDH WiFi, Pro-DASH, Bazooka, X470 Gaming Plus (& Max), B450 Gaming Pro Carbon (& Max), Tomahawk (& Max), Gaming Plus ATX (& Max), B450-A Pro (& Max) (ATX), Mortar (& Max), Gaming Plus mATX, Bazooka Plus, Gaming Plus ITX, X370 M7 ACK, XPower Titanium

 

 

So Considering this Can I put 5900x or 5950x (both are 105W TDP) stock setting on the  B450 Gaming Plus Max (ATX)?

Yes. Just that stock settings would not show them at their best.

can I do PBO then on this motherboard?

Dont, the board wont handle that.

OK. I will use it on stock settings then. also one question - in the motherboard list all tiers are categorised based on the Amps like 200A 250A etc. what is the meaning of it? is it same like Watts that we see in HWinfo for CPU under load?

It's the current output from the socket. Watts you see divided by the core voltage will give you the current I'm talking about.

will you also update this list for the AM5 motherboard in near future?

I will but when all X670 boards are so expensive, they might all just be in the highest tiers so the list becomes rather pointless

You are right. but when B650 comes on October 4th it will make sense for the budget buyers. especially building budget 7950x system with B650.

I doubt it. Since X670 are all $300+, B650 wouldnt start below $200 which is still expensive (X570 launched with good boards at $200). Not to mention DDR5 prices don't give AMD's plans a [profanity]. 'Budget" and "7000 series" don't go together even if it's $100 less than with X670.
