OK, but the test with disabling Crossfire would tell if this is an already known problem in AMD drivers: https://www.hwinfo.com/forum/Thread-High-memory-usage
MSI Afterburner monitoring should be affected by this problem too.
That was indeed a very interesting read. That person had a lot more patients than me. Thanks for the link.
I cannot help you to confirm. When I disable CrossFire (did it just now again) the 'AMD Settings' app minimizes and simply disappears. Icon in the tray also after a while. When I restart the app CrossFire is still enabled. [Gaming - Global Settings - AMD CrossFire]
I can add to that article the following:
'MSI Afterburner' leeks memory faster when I display stuff in the tray or play old full-screen games.
'HWiNFO' seems to always leek memory.
This is really sad, because 'MSI Afterburner' is about the only app that runs those GPU fans nicely. The Gigabyte app all have lots of problems. At least now you elucidated the real problem. Thanks for that.
EDIT: Some stuff happened since I wrote the above so I will report them here:
- I decided to do the optional AMD update to v17.12.2 that has been nagging me and after it restarted it reported v17.12.1 (I can swear that's wrong).
- Switched off CrossFire (took forever/screens went black) and it seemed like no memory leeks were present. 'MSI Afterburner' was running, but not monitoring anything.
- Switched Crossfire on again and hard reset the computer after 3 minutes of black screen. AMD now reports Crossfire is on.
- 'MSI Afterburner' MEM usage slowly goes up and down between 5MB and 10MB with 0% CPU usage whilst monitoring the usual stuff and reporting to the tray.
- 'HWiNFO' uses 17% CPU and never displays its tray icon. I have to manually close it in 'TaskMan'.
