r/aorus

Hey,

I got a big problem with my Aorus 5090. Of course I was undervolting it at about 2800MHz@900mV otherwise the card is hot and loud as hell 😃 Anyway that worked for about a year without any problems.

On idle the card draws maybe 25-45W and the fans turn off. All good UNTIL about march this year. Suddenly the card draws about 70-85W on idle and the fans never turn off anymore. BUT thes extra 40-50W are also on top under load. So instead of lets say 480W I get to 520-530W....

Now I have tried A LOT. 2 different monitors (single monitor setup) with different cables and 240Hz and 144Hz and even 60Hz. Gsync on and off and also ofc power management in the nvidia settings to "normal" not maximum. I tried different mainboard bios versions (Asus B650E-E) and in the bios I can do ASPM on or off or auto and it doesn't change a thing. I've also tried various other options there but it doesn't do shit.

Of course I am always doing the DDU routine and I tried about 10 different nvidia drivers. It does NOTHING. I also did a cmos reset and I unplugged the pc completely and after powering on again it's still the same problem.

Then today with a cold boot suddenly its working again. GPU idle about 40W and fans turned off. This time I just used the gigabyte control center to change the power limit from 100% to 80% (as I said I can't use this card stock with 600W and going to 75-80° while blowing my ears off). It was working. Then suddenly during desktop idle shit it went up again and that's it. Again tried for hours to lower it again but it threw these 40+W at me again (idle and under load).

So what now? I will try it in another pc as well ofc but after a year without any problems this seems too dubious. Also what's important is that the card clocks down (core clock maybe about 300MHz and the vram clock shows 50,6MHz in gpu-z, power state P8, load 0%). So maybe the controller activates or doesnt deactivate some phase or whatever that increases the power consumption?! I very much presume it has to be a defect on the gpu.

Is there anything else I can do and try? Did anyone here have a similar problem once maybe? I can't keep installing new drivers nonstop every day. It feels like I really cant do anything to lower the power consumption. Only after leaving the pc turned off and by that resetting the gpu controller it sometimes works again (but usually doesn't).

Thank you and god bless you

Btw. I already sent it back to Mindfactory to check it out but they just sent it back saying the problem cant be reproduced. I then put it inside my pc and yes, it was working (40W idle). But that's just the start of the story cause it doesn't stay that way.

Next time I would have to contact Gigabyte again first then Mindfactory and tell them to send it to Gigabyte for proper analysis. I presume that will take months then but I can't keep the shit like this 😞
