SteamVR: Vega GPU unable to return to low-power state after closing SteamVR #153

Open BPHardware opened 5 years ago

BPHardware commented 5 years ago

ISSUE: After closing SteamVR, Vega 64 GPUs are unable to return to low power state. GPU remains in a high power state until the computer is restarted.

I've only received one report of this, but the user was able to reproduce the issue on two different PCs, with two different models of the Vega 64 GPU. Unable to reproduce issue on our RX 580, but the architecture differences are important here, I think. A link to the ticket, for those with access:

Repro steps: Prerequisite: PC must have a Vega 64 GPU.

  1. Launch SteamVR. Verify that GPU Clock/Memory Clock ramp up to proper performance, and that GPU power draw increases to meet the performance needs of the application.
  2. Close SteamVR.

Expected behavior: System returns GPU to low power mode, reducing GPU/Memory clocks and power consumption accordingly. Encountered behavior: System keeps the GPU in a high performance mode, keeping the CPU/Memory clocks and power consumption elevated as a result.

We have been unable to reproduce this issue on our Vega 64. Do you have any more information regarding this issue or the configuration which reproduced it, such as the CPU Model or the GPU Driver version?

Here's a copy of the user's initial message:

The problem: After launching SteamVR, Vega 64 will sometimes (~50% chance) get stuck in highest power state. If this happens, computer will freeze on the next SteamVR launch and will randomly freeze in VR games.

The only way to "fix" the power state is computer restart.

Now the important part - it happens with two different Vega 64s (my Sapphire and reference) and in two different PCs (one from the previous ticket - Intel Core i7 4790k, GA-Z97X-Gaming 3 and now with Ryzen 5 2600x and MSI B450-A PRO). The only hardware shared between the systems is power supply and SSD. Both systems are stable in all other apps.

I believe this is not a hardware problem but some SteamVR incompatibility with Vega 64s - would it be possible for you to test SteamVR with Vega 64? I am out of ideas ...

I've attached a system report from the AMD system they're using - they performed a clean install of Windows prior to generating the report (still encountering issue after reinstall, though). Renaming the report as a .txt file - replace the extension with .nfo to view it. msinfo32-vega-power-issue.txt
