Re: 6800xt FPS drops

Usage doesn't matter and 1440p affects the CPU more if anything in certain titles. You're drawing more, smaller is why, so single threaded usage will go up. All usage tells you is if the application or game is calling for more or less GPU not whether it's working properly or not. Your clock is all over the place, which is why I suggested moving the 2 clocks within 100Mhz of each other and setting the VRAM to "fast". Skip using the OEM utility for the card and use just the Adrenaline software for best results.

 Look at my graph and you see a near flatline performance, that's the object for stability. My first TimeSpy test new out of box my graph looked like yours, red line all over and a 600 point lower score than the pic I put up. 

Your friend's PC is running a 5600X and I would doubt his score is lower or the same. He may get FPS drops in testing, all PC's will, that's part of the test. One cannot compare the performance of a 5600X with that of a 3000 series anything. Especially if one is running the X570 chipset and a 6000 series card. AMD CPU's have always been weak in the single threaded area and the 5000 series is better but not where it should be.

In any case, glad to see you got it to work better.

I now have this results, with this settings, core clock still having drops and I can't even change the VRAM, or the bench just crash....

And I was wondering, when you see those 2 graphs, the GPU usage goes down as the power consumption goes down aswell. I got a power supply 750w from Aerocool. I didn't know when I bought it but those power supply have very bad reputation. Could this be the problem ?

hi brother i have the same issue with xfx merc 6800 xt and x570 mainboard with 3600xt cpu

could u solve this problem?

Re: 6800xt FPS drops

Old question, but in any case, the graphs show a drop at a particular timeframe. Does that correspond with a frame drop situation or is it an actual "movie" part of the game where frames often go to ~25-50 FPS? 

Another thing is the Tjmax seems high at 80c+. My non-x only hits ~60c in games running on max graphics and OC'ed to the hilt. Might want to change the fan profile or get some more airflow there. Yes, in spec, too high? Absolutely in my book. AMD cards always seem to have an issue around the 77c mark on the VRAM. The "hotspot" seems to be the same way. 

Make sure you use 2 separate, 8 pin power connectors, not the split. In earlier posts (see pic below) , my settings are for a non-xt Gigabyte RX6800. The "XT" uses a tad bit more power but not enough to call for 84c. In Radeon settings under "performance", enable all adjustments then: select "manual", select "under-volt GPU" and write that number down, same screen, enable "fan tuning". Make sure to turn off any "zero RPM" option and make your own fan curve, similar to mine for coolest results. Not the least noisy but far from loud. Cooler is better no matter how you achieve that goal, to a point. settings.png

Re: 6800xt FPS drops

You have 2 BIOS on your video card, one is OC, the second is silent, the switch on the video card itself is small, turn off the PC and switch the switch to another position, turn on the PC, play, then turn it off again and switch back. It helped me and the frequencies stopped jumping to rx6900xt(but I can do it through the utility) you have only this way and only when the pc is turned off!!!

Re: 6800xt FPS drops

how important is it to use 2 seperate Pcie cables can it cause performance loss in older titles like battlefield 4,league of legends,apex legends? currently i am using a daisy chain and i would have to get another psu if i want more pcie cables.

Re: 6800xt FPS drops

One six-pin cable holds 75 watts, an eight-pin cable holds 150 watts. And do not use adapters with molex for 6-8 pins. Given the voracity of modern video cards, the cables simply can not withstand such a load, they will fuse and there will be a short circuit.

Re: 6800xt FPS drops

It's not about Games, in any game, disable the frame rate limiter and the card should work at full capacity (if again it will not be limited by the processor.) Your card has a peak consumption of 270 watts in the BIOS OC, BIOS Silent 265 watts.(2 eight-pin cables of 8 pins 150 + 150 watts) On all modern power supplies, there are usually two cables of at least 8 pins for powering the video card.(but the cable is divided into several (2 by 6 pins 2 by 8 pins)) all one cable holds 150 watts. It may also be that the bios for a processor with a limit is sewn on cheap motherboards( that is, you have a 5800x processor with a TDP of 105 watts, there is no TDP limit on an expensive motherboard, and under load the 5800x processor on an expensive board will work not at 105 watts but at 200 watts, and on cheap boards it will work according to TDP, that is, if under load it rests on a TDP of 105 watts at a frequency of 3.5 ghz, it will not raise the frequency higher, although it can work at 4.7 and higher. (it already depends on the subsystem, of course)
