the Problem is that your Monitor panel doesnt use "LCD native" standard for 75hz
I upgraded my monitor today from the MSI Optix MAG271C 1080p/144hz to the HP Omen 27i 1440p/165hz
Suddenly THE vram clock speeds are up at almost max while idle? The monitor is the only thing that has changed in the set up.
The 6800xt fans are also on now all the time where as before they were always inactive until temps started creeping up to 60ish which they aren't at!
this happens because your new Monitor doesnt use "LCD native" Standard
you Panel is "oced" by HP to run below specs - thats why AMD GPU forces the VRAM on a higher powerstate to maintain stability
you can "fix" that by changing "Blanking" and/or "Front porch" with CRU to be back in spec of "LCD native" - this can cause problems with your Monitor and WILL MESSUP FreeSync Range (as it has effect on Pixel clock); also it is considered OC when you raise the pixel clock - and not all Panels can handle it (yet it is very unlikely to brick it - as its only a driver hook and can be reset)
about higher Temps - actually i dont know why some people have this issue; my RX 580 4G stays between 30-35°C idle with highest VRAM powerstate (1750MHz oced to 2000MHz) - also my fans doesnt spin.
you could try an older driver - as some drivers doesnt use the "LCD native" check
Thanks for the reply.. lots of info there but jesus that's insane. Honestly appalled and it doesn't look like a new issue either!
People really need to go through that many steps just to stop this from happening and from what I'm reading it can just cause potentially more issues
Have AMD made any comment on this as to fixing it or are they trying a 'this is intended' approach ?
Consideration: I have the same monitor connected to a 1050 Ti.
No problem with the consumption, VRAM in perfect idle state.
AMD "approach" is really needed?
actually i think it is not needed to give it the highest powerstate - but this wouldnt be in "standard" specs
best would be if all people report this as bug
especially those who now have higher temps and fans always spinning (because this is not intended)
I reported this bug via the bug tool and by contacting AMD directly. Got a reply within 2 days asking me if I would like for the report to be forwarded to Driver Dev Team. I replied and confirmed that I would indeed like my report forwarded to the Dev. team. Got a confirmation email stating that my request is being reviewed. I urge everyone else to do the same. Wait for the first reply from AMD and make sure you respond and tell them to forward your report to the Dev team.
I did the same yesterday via the bug tool. I had contacted their support earlier in the week and all they came back with was 'can you try turning the monitor down from 165 to 144 or lower. I replied 2 mins later and reiterated id done all this and even linked this thread.
Heard nothing back from them since.
There's no way they aren't aware of it
as it is actually not an important bug it wont get high priority
but i hope that you also reported that temps are getting higher and fans are spinning - than it will get a higher prio
