I was recommended in a previous thread to start a topic about this
Just updated to newest version of avast and along with the new GUI processes (two AvastUI.exe’s) my GPU now cannot idle, which causes higher temperatures.
I have confirmed it is avast causing this by disabling avast in safe mode then booting with everything on, except avast. Rolling back to previous versions of avast did fix this problem, although it’s not wise to be using old versions for too long obviously…
I custom built this pc so I have everything tweaked exactly the way I want / need (Windows and GPU settings wise)
Idle temps / core clock of GPU were always ~20c and 135mhz
After updating (with a clean install) of avast, my GPU at idle will not clock any lower than 1039mhz and idle temps are now ~35c.
A main focus of my PC build is keeping it cool. While these are still acceptable numbers, why should I let any program, let alone my anti virus prevent my system from reaching its max idle state?
Using GPU-Z I’ve notice a spike every 30 seconds. It shoots to the maximum GPU Core Clock and GPU Memory Clock for a moment. I’ve got a GT 720 which runs at only 8x and in a tiny SFF case. Playing a HD video only uses 135MHz Core Clock 202.5MHz Memory Clock. I don’t see why shooting up to 796.9 and 450 correspondingly is necessary. On a side note. Check to see that your browser isn’t using maxed out Core Clock all the time. Mine was and I had to disable hardware acceleration in my browser and use the default settings instead of HTML5 Video Player on youtube. That’s how I discovered this little quirk with AvastUI.exe. Killing the process stops the spikes. The newest 2015.10.2.2218 doesn’t change a thing.
I have exactly this same issue. I have a Zotac 970 GTX and after playing any game and exiting to windows my GPU has issues idling. Here is a screenshot of MSI Afterburner reporting the clock spikes: http://s1.postimg.org/bpxdmjv0t/gpuclockspike.png
As you can see it spikes every 30 seconds just like doodah70 said. After killing avastui.exe the spikes stopped completely.
what was causing it and fixed how?
clean install of avast using the tool has not fixed it.i dont want to replace avast but it looks like my only option.
