6800 xt dropping clocks

So I was lucky enough to get a 6800 xt on launch direct from AMD and received it yesterday. I am having a little bit of an issue with the performance in game regarding the boost clocks and GPU load randomly dropping. While in game the gpu load will drop to 40ish% and the gpu clock will drop to 550ish mhz. This will cause a framerate drop to 15-20 and stuttering for a few seconds before the boost ramps back up. I have noticed this most of the time while playing Destiny 2 and going from a tunnel area with no npcs to an area that has a bunch.  This happens both while using the preset performance options in the current version of the AMD software and applying a manual OC (it happens less with the OC). Currently I have the OC set to: min freq. of 2400, max 2600, voltage 1100, power limit at +15%, Zero rpm fans disabled, radeon chill disabled, radeon boost disabled.

Full system setup is:

Asus x570 prime pro

3800x with PBO enabled

32GB gskill trident z 3200mhz xmp

Corsair RM750i psu

All storage is on samsung 970 evo plus NVME drives with no raid set up

CPU is water cooled and holds 50-60° and boosting to 4.6ghz and only 25-30% load. GPU temp is only 65-70° and power draw is 300w or less the whole time.

Has anyone else run in to this yet or figured out the reasoning?

Don't @ me that I should have used 140mm fans.... only had black 120s in stock when the build was done

Re: 6800 xt dropping clocks

I am seeing it far far less when I can manage to keep the GPU load up and manually OC but it feels like as soon as it hits an easier part to run the system is going in to a power saving mode instead of keeping the boost up.

Re: 6800 xt dropping clocks

Its strange tho. Im only having this issue while playing black ops cold war and modern warfare. On games like CSGO, Apex Legends, and NFS heat the clocks are stable at 2400-2500mhz...

Re: 6800 xt dropping clocks

I’m going to try tonight to super sample my resolution to 6880x2880 and see if that will force the card to hold boost clocks and load. I’ll let you know what I find... maybe some of these titles are just too easy for it to run?

Otays, was just testing for the last 25-30 min and it turns out the answer is crank it up. I set up initially with 200% resolution scale but this was a bit of an overshoot at a whopping total of 19.9 million pixels (just under 8k resolution  for the total render). It was definitely playable and held solid around 45 FPS and the boost clocks stayed pretty consistent at roughly 2580 MHz. I dialed back the resolution scale to 150% so it was rendering at 5160x2160 and that was the sweet spot with boosts holding solid at 2540-2560 and the framerate never dipping below 85 FPS. I guess the solution to our problems is crank everything to 11

Re: 6800 xt dropping clocks

I have those issues on witcher 3 and Il2-sturmovik:Great Battles but when i alt+TAB it runs back to normal boosting and keep running on full potential.

Other problem is when i exit games and back to desktop i have stutters on mouse cursor moving like my card is producing no clocks at all. When im moving super fast circles with mouse it goes smoothly but slow moving mouse cursor is stuttering. Only restart helps. I found that when i run a movie clip its goes back to normal but when i close app, mouse on idle  stutter again.

My spec:

Aorus Z390 Pro, Intel I9 9900KF; G-skill trident Z 2x16 Gb 3600mhz, Sapphire 6800xt, Corsair RM750.

Re: 6800 xt dropping clocks

I managed to find a different solution. It seems that there is a issue with AMDs software. I tried running a slight OC on my card through ASUS GPU TWEAK II - which resulted in stable clocks during the whole day. The clocks stayed stable at more aggressiv overclocks aswell and without changing any ingame settings to put more load on the card. 

Give it a try :)

Re: 6800 xt dropping clocks

resets frequencies due to bad components and bad software or even because of temperature. There are no other problems

i suspect a bug in the game - or either a driver bug
