Vega overheating on Desktop

Technical Issues and Assistance Hardware
#1

With all updates installed and only on desktop (xfce, stable, 4.15 kernel), my PC draws 30W more than under windows. And it all seem to come from the Vega card. It becomes very hot and finally crashes the computer. It is used as a secondary card. My main card with display is a 1080Ti. The Vega also has a display connected (the same display, because it is not recognised in programs if not connected).

That's a pretty big issue, because the fan doesn't go faster it stays at would the card be in power save mode although the overheating is clear (can't put my hands on it).

It would be great if a quick fix could prevent it from burning. It seems the kernel just freezes and let the CG overheat further.

The quickest fix: disconnect it.

What follows is supposition as I don't have the card.

You could check which driver the card is using, e.g. inxi -G. If it's the wrong driver it's possible the sensor data is wrong or it doesn't know which fans are available where. inxi -Fxxxz will provide useful information for others looking at the thread.

Check your TLP settings in /etc/default/tlp to see what power profile is set on the card; the current Manjaro defaults are:

# Radeon graphics clock speed (profile method): low, mid, high, auto, default;
# auto = mid on BAT, high on AC; default = use hardware defaults.
RADEON_POWER_PROFILE_ON_AC=default
RADEON_POWER_PROFILE_ON_BAT=low

# Radeon dynamic power management method (DPM): battery, performance.
RADEON_DPM_STATE_ON_AC=performance
RADEON_DPM_STATE_ON_BAT=battery

# Radeon DPM performance level: auto, low, high; auto is recommended.
RADEON_DPM_PERF_LEVEL_ON_AC=auto
RADEON_DPM_PERF_LEVEL_ON_BAT=auto

I had high power draw and temperature with my Studio 1749 (HD5650) with the upstream default of RADEON_POWER_PROFILE_ON_AC=high; however, that uses the radeon driver, not amdgpu, though both share a common power management interface.

The power profiles are all like in your reply.

#5

Hmm... it only shows the nvidia driver which isn't useful when we're talking about the AMD card...

lsmod will give a full list of loaded driver modules.

The other suggestion is to switch to the testing or unstable branch to see if a newer kernel introduces any fixes - IIRC Vega support was new with kernel 4.15, so 4.15.0 will be pretty "raw" still.

#6

I only have AMDGPU and lsmod also reports amdgpu, nothing fancy installed, only the defaults regarding drivers.

Maybe there is a way to report the bug to upstream/AMD?

#7

I am sure you already know so just as a reminder, the behavior you describe can quickly end the life of your gpu or even motherboard.
I know from personal experience, lost a pci gpu a while/way back in the day. :grinning:

#8

Disconnecting the card is not enough, I have to completely remove it from the PC... Anyway, better report it upstream as fast as possible, before someone else burns his card?

#9

Kernel 4.14 draws as much power or more, but at least let the fan at full speed all the time. So you loose your ears, but not your GPU at least :wink:
