B450 Chipset overheating with Ryzen 9 3900X + RX5700XT

Postby Jkin » Tue Aug 11, 2020 10:31 am

Hey Guys,

I am totally new to this project and have an overheating issue:

B450M Pro VDH Max MSI Board, Ryzen 9 3900X, RX5700XT GPU:

While folding in medium, the mainboards chipset heats up to more than 90°C and sometimes the system will crash and restart.

The boards chipset has a passive cooling block.

Could it be that F@H is too intense for this setup? Could an X570 board with active chipset cooling solve this issue?

Note: With the benchmark tool HeavyLoad similar chipset temperatures are reached while, for example, Prime 95 causes only average chipset temperatures being at 100% CPU load.

Thanks for your thoughts and ideas.

Try to disable PBO (precision boost overdrive) and any overclocking. Poor cooling should never lead to a crash - only thermal throttling, even if it brings the CPU and GPU down to ridiculously low frequencies. So this sounds to me like either an unstable overclock or a bad PSU. Once you've solved what causes the crashes, then you can start looking at improving thermal performance.

A UEFI/Bios reset and installing the newest firmware and Bios might improve stability. Some early release versions might under-report power draw to trick reviewers or something, typical MSI behavior.

What do the frequencies look like in Ryzen Master and in the Radeon software?

(Folding@home does not recommend or support overclocking; it's better to have accurate and stable results than unstable and incorrect results.)

Ok ... so firstly as you have noticed benchmarks vary ... and to be honest FaH will work you system harder than most/all benchmarks (except perhaps FaHBench once it is up to date.

Secondly lets get your temps under control ... I am hoping you can access the FaH Advanced Control rather than just the Web Control - If so open this and click on configure - select the CPU slot and edit it input say half your available threads into the field for number of threads replacing the -1 that is there - click on OK then save ... This should immediately reduce the CPU load to 50% (ish, as the GPU and other system stuff will add a bit) ... If this doesn't work take it lower ... please note if you increase count again in future this may only take effect once a new WU is downloaded.

Now that your temps are at least a bit lower (hopefully) you need to work out quite why your system is getting this warm ... There are quite a few topics in the forums that cover this type of thing ... a lot of the time it is down to poor case ventilation and/or stock CPU coolers ... a passive cooling block needs good (hopefully reasonably cool air) to function ... just a couple of first steps - if they work (or not) do come back and post more questions ... posting screencaps from something HWinfo will help people advise you - and once you have posted a few posts then the moratorium on new members posting images will be lifted.

Hope this helps as a starter for 10 ... If you have problems finding the Advanced Control it is called FAHControl and in windows can be found in the icon tray bottom right hand corner you may need to show hidden - your should find a FaH icon - right click on it and choose advanced control ... in you are in linux then you may or may not have it installed depending on type/version but I'll need to let a linux guru help you with that.

... and I'll let previous poster walk you through the techy approach :)

Thank you so much for your fast replies.

The bios is the most recent one and no overclocking option has been enabled.
I will report back once I looked further into this issue, especially regarding power supply and air flow.

Are you sure that you are looking at the chipset temperature or at the CPU one ?

Do you use AMD stock cooler ? Is your case ventilated enough ?

Many AM4 motherboards aren't made to have the CPU maxed out.
They're made before 12 and 16 core Ryzen CPUs were thought to ever populate those boards.
Their VRMs basically run at maximum capacity.

If you run a CPU air cooler, the first thing I would do, is make sure that the air flow exhaust of the CPU is actually passing by the VRM heat sinks.
If not, the VRMs won't get any cooling.
The second thing I'd recommend is to enable eco mode in under the AMD overclocking menu.
Eco mode will lower CPU TDP, while still allowing for overclocking. Then fine tune, or adjust the wattage/amp ratings proportionally to one anther as you see them under the default ECO setting.
Eco mode allows you to run your CPU at lower power usage, while still allowing for manually modifying the parameters.
For instance, if your ECO setting (under PBO) says 65W, 70A, and the board can go a little higher still, you can increase the wattage to 75W, and the amp rating to 70*75/65 = 87A.
Additionally, AMD PBO allows you to manually set the maximum temperature. You can set it to 5 degrees below comfortable; like 90C, or 85C.

If you have a water cooling, then you'll just need to add a case fan, blowing on the VRM heat sinks.
It's mandatory that these get actively cooled!

The X570 has active cooling because it inherently uses more power. Unless you trace the cause of the overheating, it is unlikely the X570 will be a solution in and of itself. Also, I don't see any micro-ATX X570 boards listed on Newegg...

That said, ANY motherboard/chipset with a more robust chipset cooling setup (e.g., B450 Mortar Max) may be somewhat better when Folding full-time. Cheaper equipment in general is not designed for full-time, full-load use.

What do you have for intake & exhaust fans? You may find that a more efficient intake fan (e.g., Noctua) may provide better airflow over the chipset heat sink. Also make sure there are no drives or other parts in the way.

The cool thing (pun intended) is that the active cooling only kicks in when the chipset reaches 60°C. In my setup (Ryzen 9 3900X, GTX 1660S), with decent enough air cooling, it only spun up once the room temperature exceeded 28°C. :)

Ah, yes. Cooling a Ryzen 9 3900x on a B450 motherboard. Fun and games. I'm running an RTX 2070 Super in mine.

1). Case airflow - Make sure you have a high airflow through the case. 120mm/140mm fans front and rear
2). cpu cooling - this one gave me a lot of bother. I tried the stock cooler, a number of my air coolers and 120mm closed loop water coolers, I didn't like any of them. I ended up getting a new 240mm closed loop cooler.
3). VRM cooling - I have a 40mm fan ziptied to the cpu cooling block blowing air directly over the VRMs to ensure the air circulates. The case fans move plenty of air but sometimes need a little help hitting some spots.

There's a few other tweaks I've done like
*). reducing to 12 threads and making sure each thread runs on a separate cpu core
*). reducing cpu max power state to 99%
*). reducing the gpu power limit to 60% (someone else had suggested 50-70% and I had a play around with it)
with these tweaks my power draw dropped from ¬400W to ¬250-280W with a minimal drop to my PPD, which is roughly 2 million ppd for the system

Just found out that the B550 motherboard is available in micro-ATX. Slightly downrated version of the X570 (e.g., only PCIe v3.0 lanes in the chipset, but supports the PCIe v4.0 lanes in the CPU). Almost as expensive as the X570, too!

There are other relevant tweaks in this thread:

You may want to try some in lieu of your power state limits.

I am using HWMonitor to read the temperatures: According to HWMonitor the mainboard temperature (where is the sensor?) is the highest (max. 95°C). CPU (stock cooler!) did not exceed 75°C.

The case has additional fans, but probably not enough.

Regarding the proposed BIOS and F@H setting tweaks:
For now, I will leave the BIOS on default values as well as F@H.
I am going to try a MSI X570 Board (Full ATX, it fits in the case) with active chipset cooling and better/bigger cooling blocks, I will also try a different power supply.

This might do the trick :)

If you limit the boost clock speed (or disable it) on the CPU, you can shave another 25% off the power draw.
Running mine at 3800MHz, 1.05V, no stability related failures since I got it (4months).

Adjusting via AMD ECO// PBO temperature and wattage is much preferred over manually setting the OC.

Es fruto de varios problemas, las bios no han sido fabricada para procesos intensos de calculo, por lo tanto la version 3900x tiene overclock de fabrica al igual que la rx5700xt, al acabar con la letra ´x´, primero tiene que deshabilitar el overclock de su cpu en la bios , oc tweak, o ponerle un ratio fijo para que el solo no varie, luego en el controlador de la targeta grafica debe configurar el ventilador al 100% a 70º, ya que por defecto no esta ni al 70º, ademas por defecto el overclok llega hasta mas de 2100mhz , lo cual es un peligro, y tendra que ponerlo en modo manual solo hasta 1950mhz. Yo la CPU la desaabilitaria en folding at home.

Yo tengo estable la rx5700xt a 2080mhz a 1137mv, y es lo maximo que lograrás. Si alguien obtubiera mas es porque el chipset es superior al B450M.

Si te compras cpu y gpu con final de letra que acaba en x, ten buena refrigeracion, es una pena que tengas un 3900x, y te halla pasado eso.

Los autoverclocks que hace el oc tweak de tu cpu y los de la gpu, son poco ajustados, ya que los voltajes se disparan por defecto, por eso, en manos de expertos, se realiza manualmente undervolt, para que la potencia baje y no alcanze temperaturas elevadas, al ser este auto ajuste de fabrica o de serie una mierda, el fabricante advierte primero de la perdida de la garantia, por ello es mejor ir probando de menos a mas, y no confiar en el auto overclock.
