RX6900XT power consumption too low

Hi there,

I have the problem that my RX6900XT only consumes a maximum of 125W when playing and therefore the FPS are very low. When I restart the PC the power consumption is normal at 225W.

Tuning Control is on Automatic

Has anyone already had the problem?

Driver 20.12.1
I7-8700K
Gigabyte Gaming 5 Z370
16GB RAM
be quite 750W

Re: RX6900XT power consumption too low

I am having the same problem.

I just got a 6900XT and my power consumption is low in games (~100 watts or less). I don't know how to ensure it stays reasonable like 200-250W. I have 850W PSU and my 3070 ran significantly better in the games I play. However, Timespy score is much better on the 6900XT but power consumption was peaking at 280 watts. Need consistent power consumption it seems.

Re: RX6900XT power consumption too low

try reinstall the drivers, seems a driver issue, before reinstall use DDU the remove all old drivers left on the system.

Re: RX6900XT power consumption too low

I am having same issue. Reinstalled drivers. DDU safe mode twice. Reinstall adrenaline and drivers.  Increased the power limit +15%. Overclock and undervolt negligible results. Hitting 200-240w then dropping down to 89-120w. Windows power plan checked.  Not getting consistent power. Tried with previous 850 w power supply same issue. Drivers or settings I am missing?

Re: RX6900XT power consumption too low

Wow that's a weird problem. I don't have it, but seems kinda sorta driver-related. Akin to forcing PCI-E power compliance on (to not exceed the limitations of power provided purely by PCI-E slot itself with no external connectors). Does that happen with different driver versions in different applications or only in a limited number of cases? Does anyone with reference design PCB have it? How many 12V rails are there in your PSUs and if multiple, what is the max rated load for them? 

OK, I checked, so EVGA Supernova 1000W G5 has single 12V rail so definitely not an output issue.

Asus rog z390f, i9900k, Asus TUF rx6900xt, samsung 16gb 2666ghz. The same problem with FPS in games.
Apex legends, Warzone, these games have fps below 150. Power consumption does not exceed 100 watts. I thought that my video card was defective, but it turns out that many have such a problem.

Re: RX6900XT power consumption too low

Are you getting what you should fps wise when you compare to people on YouTube, 

 

I actually think the readings you get there is no problem in rust I only use like 90 with my 6800 but I get good fps on max gfx

Re: RX6900XT power consumption too low

A friend of me got the same problem with a XFX Merc 6900XT, Benchmark the card pulls full 300W but ingame just about 80-90W. Some times it goes up to 125 than dropes back to ~80-90. Drivers are up to date, graphics settings are clear, no vsync or fps lock.
temperatures while gaming are about 50 °C. We testet OC and Silent mode but nothing changed really.

XFX Merc 6900XT
Power-Supply: 750W

Re: RX6900XT power consumption too low

No power issues over here with the 6900XT Merc, over 270w before I started capping my FPS to monitor refresh. I would suggest updating the BIOS but the Intel system should be more stable? We had a lot of issues with specific games crashing, we update the BIOS and then bam, everything works. Ryzen 5000 and X570 is still being ironed out.
