Rx 480 strange behaviour

Hey guys, recently noticed that my Rx 480 8gb has been showing strange behaviour:

•pegged at 55-60W idle after a gaming session.

•reports 100% utilization in Radeon control •task manager shows pegged at 70% video encode

•1800-2100MB VRAM utilization on desktop

•gpu clock pegged at 1328mhz

•temp: 60+°C

•After about 5 minutes the behaviour starts again.

 

Running 22.4.2 drivers (same behaviour on previous release drivers)

Previously only sleep/power cycle would reset watt useage, now changing resolution resets power draw but 70% video encode remains.

 

R5 2600x

ASRock b450 Pro4

XFX XXX OC Rx 480 8gb

Seasonic Focus gm-550w gold

Windows 10 21H1

 

 

Any thoughts on this?

Old card.  Maybe the TIM dried out.  Has it been refurbished relatively recently?  GN has a video on care and feeding old video cards

Not a pro, not even very good.  I’m just old and have time currently.  Assuming I know a lot about computers can be a mistake.

 

Life is like a bowl of chocolates: there are all these little crinkly paper cups everywhere.

I follow where you're going with that, but the temps are actually fine when it's not doing this weird behaviour, like in game it sits about the same as when it's doing this pulling 115W. TIM was repasted when I bought it according to the seller and it was only once the weather started getting warmer that I noticed since the window is closed now. 

 

Very valid observation, but I don't think repasting the card again is going to fix the phantom extra 40W it's pulling at idle. And when I booted into safe mode, cool cucumber. It looks like something is going on with the encoder where it is just like going ham without being given any instructions.

So yes to refurbishment. My memory is people sometimes put odd bioses on 480s to turn them into 580s I’m not sure what the results of that are.  Generally if a chip has a problem nothing works at all though.  It would have to be a subtle thing.

The strange thing is that it only started doing it recently. It's def quite the champ at the games I'm throwing at it, and it has always idled between 45-60C (45C was in a room air conditioned suitable to be a meat locker).

 

I just can't for the life of me figure out what it's trying to video encode(video encode pegged at 70%)

Maybe look at the events viewer or task manager or something and see if something is trying to encode?  I dunno.  it is weird.

Did you by any chance turn on AMD relive or instant replay?

Relive is not installed, for some reason record desktop was enabled, once disabled it dropped about 5-7W. Any other things on by default that I never knew were on?

AMD relive is a driver level program, its installed automagically, i’d have to put my 570 to tell you exactly where but on the home page if the driver on the bottom left you csn find the relive settings

I went to the ReLiveVR tab in Radeon and it says "not installed"

ReLive folder is also empty

interesting, still, make sure that you have any recordinf feature off like instant replay or instant gif

Just got those off as well, sitting between 42-47W. When I got this card 2 yrs ago (second hand) it would sip away at 17w idle

I say try a DDU and reinstall driver? maybe reflash stock vbios again and repaste if at all needed, my 570 would get about 20-30w idle and I have just recently (week and a half ago) switched from it

I think I am gonna repaste and clean the heatsink and fan this weekend, any recommendations for good thermal paste replacement for it?

The phantom encoding was driving me crazy, I think I can handle the ~45W idle for now.

Yeah, I think the high idle is an issue with driver at this point, not anything to do with driver settings though, maybe try an older driver?
