AMD Ryzen 9 3900X Tested on Cheap B350 Motherboard

[_Flare]

Oh not again please. There is nothing magic on this subject and nothing wrong with ‘cheaper’ chipsets.

I want to agree but maybe some current steering is different, but then, why do 2700X work and boost well and 24/7 on all A320 with VRM coolers and even without coolers?
A 3700X shouldnt be any problem on A320 physics wise ... but well I think sadly it will be product-politics

You suggested it wouldn’t work. I proved you it would as it’s officially supported by the manufacturer.
I can’t say for sure the mobo will handle the power perfectly but honestly the A320 was designed to support 95W of the 1800x and the 3900 is only 10W higher. I doubt manufacturers design custom bios to power limit specific (and old!) motherboards. More expensive chipsets were designed for series 1000 as well and the power figures were the same.

I honestly don’t see the 320 as ‘special’ as some users have claimed on these pages over the past months. It just lacks the specs highlighted by AMD (Raid, overclocking etc). That’s it.

Thanks so much for this @W1zzard

Now I know my board can handle the 3900X I plan to order once the 5700XT arrives

At that temp sustained wouldnt the VRM fail after quickly because of the 5k caps it likely uses? Meaning that at 105C or higher it will fail after 5000 hours.

Are you planning to run the CPU at 100% utilization 100% of the time ?

Not only that games and most professional workloads don't use the cpu at max, but whatever job the CPU does eventually finishes and things go back to idle.

Unless intentionally trying to break the VRMs with some power virus software (CPU cryptomining?), this is not an issue.

 

[Tsukiyomi91]

still, it's an interesting find. With adequate cooling, I don't think the VRMs are gonna get toasty.

 

[phill]

USER=1]@W1zzard[/USER] can we get an additional test with a fan mounted someplace for cooling?

Just my exact same thoughts, would it be possible to add in an extra test for this please?
Very nice and impressive review and I agree with the first line in your conclusion about Intel charging us twice...

So while Intel forced all Z270 owners to buy new Z370 MB for the 8th Gen CPU's because of the lake of power pins, here we see that old Cheap B350 board can run HEDT league 12C monster w/o a problem.
Shame!.

That was a complete rubbish lie, as demonstrated by der8auer:

... who taped almost half of the power pins and the CPU was still working perfectly (and overclock as well)

We know W1zz is camera shy, but who want to see at least a time lapse of W1zz at work, the setup and everything ?
Let it be heard people we might have a chance of convincing him.
C'mon @W1zzard only thing you have to loose is have to put some pants on.

Watercooler is Ok. Just add a good fan over your motherboard.
Btw, the system below is using a 2600X, it's not a Ryzen 3000 CPU.

 

[BoiseTech]

Apparently nobody googled this:

Clickbait title says B350, but he does this on a A320 board.

That's a nicely suspended fan. What's the impact once you close the case?

Not in that video he doesn't. He says he's going to try it on A320 in the next video.

I stand corrected, Don't youtube while working.

Sticker shock, I just looked at X570 prices. I can see why we're interested in 300 and 400 series boards.

 

[Vlada011]

Is it 3950X slower in single threaded applications then 3900X?
I have some bad feeling... maybe I'm wrong but something tell me that investing in AMD PCI-E 4.0 before Intel show up with 10th Gen could be mistake.
Maybe not some huge mistake, but enough to think Why I didn't waited just to see what they offer.
At least for people who have enough strong platform to provide normal performance few months more.
These insanity with motherboard prices... I have feeling that Crosshair VIII Formula will cost 350$ when Intel show up.
I had Crosshair 4 Formula.

Because of that if 3950X performance in single threaded applications are lower then 3900X I would choose Crosshair VIII Hero and 3900X.
Crosshair VIII Hero for 350$ is max best option. Too bad that would be my first "skinny" ATX motherboard after 7-8 years on premium E-ATX.
ASUS ask double more for Formula.... For what, VRM Block? Heatkiller IV PRO Black Copper on CPU, PCH and VRM default cooling.

Some people do, the crunchers at our WCG team but I doubt that any will attempt this test in a permanent installation, if so we will hear about it

 

[Vlada011]

Two guys with X99 platform who bought PC after me 2-3 months agree to delay switch to AMD. I couldn give them better advice before week.
Today one of them told me he almost decide to switch to 3900X.
Later I saw information that Intel even with new generation want to go with obsolete PCI-E 3.0 directly connected with OS speed on new systems.
Same thing was on mind and to me in that moment, I afraid information about Intel 10th Gen will only increase number of people who buy AMD Zen 2.

One thing is sure, difference between single threaded performance on Intel and AMD can't be any more excuse.
It's insane if someone buy Intel because of that. i9-9980XE is faster then 3950X 5800 vs 5300 single thread Geekbench.
Multithread is 61.000 AMD 3950X vs 46.000 Intel i9-9980XE.
People who decide to buy Intel because of that is abnormal person.
That could be move of someone who need i3. Not enthusiast who want hard core PC Machine.

 

[mcraygsx]

INTEL would've charged us more then twice in same duration. Excellent coverage as always.

 

[Assimilator]

@W1zzard great work as usual, would be useful IMO if the article mentioned what temps these VRMs are rated to handle versus what they put up with.

Funnily enough, Asus' own specification page for this board states "Supports CPU up to 8 cores", this article is a pretty god advert for them!

Maybe you should consider re-running your Zen 2 watercooling overclocking tests with a fan pointed at the VRMs?

 

[Cr@zed^]

I' m so glad I can keep my CH6. today my 3700X will arrive, It's like X-Mas when I was a kid

 

[kurosagi01]

Quite pleased to see W1zzard tested 3000 series on the same motherboard I have,saving me needing to upgrade if I do fancy upgrading to 3000 series.

 

[ORLY]

Asus Prime X470-Pro
MSI X570-A Pro
MSI MPG X570 Gaming Plus

Which would be better VRM-wise?

 

[bpgt64]

So, would it be smart to wait for a mono block for a X570 motherboard then? Just to make sure temps are reasonable.
