thank you so much for your previous post, you may have actually saved the day & fixed the issue I was having!!! appreicate your post man on reducing power setting in the power tuning. Tested it today & watched the junction temp which is the one that I’ve been concerned of & it was lower & ran great!!! I’m still doing more testing with tuning & trying to find that sweet spot with the reduced power setting in Adrenaline software.

Yes reducing the power setting is always the best one can do for a GPU. My graphics card was so insanely overheating that it kept shutting off the whole computer with greenscreens.
After reducing the power setting to -50% the fans were running with 45% most of the time and the card was ultrasilent, and all games still had perfect FPS performance… except Blair Witch and Flight Sim… these two games ran perfectly with -10% power setting but not with -33% or -50%.
The same goes for the RAM, with the recommended setting of 1.4500v volts the RAM became significantly hot to the touch and this is not normal because I have read several times that RAM should not be hotter than 50°C or it will get damaged over time.
After reducing the voltage to 1.3600v the RAM is now cold to the touch even while gaming Cyberpunk with no performance reduction at all.
Having the system cool and quiet and rocksolid is always good and healthy for the hardware instead of trying to bring it to the limit.
But too much undervolting makes it unstable too so don´t undervolt RAM or CPU too much or a BIOS reset might become necessary. The computer will not boot anymore or hang in a bootloop when too much undervolting is set.
The Radeon will only become slower when reducing the power setting, not much but still noticeable when reducing the power more than -33%, but it will never shut down or greenscreen the computer anymore after a setting of -12 to -15%.

Which costs you performance as far as I understand this option.
You could probably simply undervolt and keep the same performance while running cooler.
Or is that power tuning in AMD software just undervolting?

I’m not sure it will cost anything in performance but I will do some testing & advise. the power tuning in AMD Adrenaline software is not undervolting. There is an option in the Adrenaline software I believe to do undervolt hardware if one wishes to but I don’t want to do that. As @GamingCat2130 mentioned in previous post lowering the power a little gives us some good headroom on temps of GPU. I can’t speak for @GamingCat2130 but I’m currently using the RX6900XT on a PCIE 3 bus. I’m curious once I upgrade to the PCIE4 bus on a new motherboard if the higher temp issue will be a thing or if I’ll be able to give GPU full power & the temps not raised to a bad temperature.
a lot depends also on case !!, yes , a more roomy case gets better airflow. and in the past
i have played with one side open and having used a small external fan , strategically aimed. before next buy i also will look at specs, some brands just run hotter.

Nope.. I’ve refrained from commenting on the recommendation to turn down power but You are very much right Coppersens. Turning down power reduces overall performance and it is a separate setting than turning down the voltage which is the better approach as the Radeon software will auto adjust back to a higher voltage if required and lower the voltage and the resultant heat if the gpu isnt being utilized at the higher clocks. But I’m not interested in really arguing with the person who posted it so i let it be.

what would you suggest in making adjustments to voltage in the AMD Adrenaline software? I’ve turned down the power some to the GPU in Adrenaline software but am still getting great performance from the card. So much so that I’m seeing 2200 + Mhz clock speeds still on GPU with the power setting lowered in software. Let me know what voltage adjustments I should make & the increment & I could try that if you think that will help lower the GPU temps.
My settings are unique to me as i am using a 6800xt (albeit a heavily overclocked one from a very reputable brand when it comes to radeon products)
In the sim my junction temps do not go higher than mid 80’s. Note the voltage all the way down to 1030. The card will drop to a lower voltage when there is less demand on its processing power and adjust up if the need is there. Used in conjunction with lets say a frame rate lock of 30fps using the radeon chill section in the settings your card should not be overheating .. unless of course you have poor case cooling and that’s a different issue altogether
Also note my power limit is actually maxed above and beyond the default 100%. You do not need to do this because i assume you wont be overclocking but i would highly recommend you put it back to its default 100% as you are crippling your clocks that way.
Thank you for sharing your settings. I’m not planning on OC my RX6900XT at all, have no reason to. I will take look at my current settings & see what my voltage settings are at as I haven’t messed with those at all as of yet. I will return power to 100% & maybe try a lower voltage setting to see what kind of performance I can get from it.
sorry to hear you went back to Nvidia. that RX 6900 XT card you owned is a great card. I’m only now starting to see it’s potential after reading some of the posts on this forum & trying a few different methods to bring temps down & get great performance. That’s strange to hear your RX card fans only ran when idle. Using the Adrenaline software I like the Zero RPM option & the ability to manually change fan speeds at whatever temps we want etc. Did you play with the Adrenaline software at all?
Thanks again for your post. I was able to do some testing with voltage settings. I lowered voltage setting however it didn’t seem to help my temps much at all. I tried some different voltage settings & brought it down to low a couple times I believe as the sim would crash on me. Once I didn’t lower it down as much it was stable. I also appreciate the reference to the Radeon chill settings. That has made a big difference for me. I turned on Chill feature & tried a few diff fps limit settings which worked well for me & brought temps down. I’m able to run at 3440x1440 with almost all ultra settings (i have few turned off hence reason I said almost all). I can’t recall my LOD settings off the bat atm but I can look at them when I get a chance & edit this post if anyone is interested in them. I’m getting great fps & temps are good as well, sim ran great/stable for me yesterday while testing.

Post gives me a giggle … got my cooling yesterday now I just need the videocard to show up.
How much did that set ya back?
Well … uhm … yea … almost $400 USD I also got a keen spiny flow indicator for $36
Failed attempt at distraction … there was a minor lottery win involved recently.
Yea I paid too much for that too, saw it on a Linus goof build (wish water cooled) and had to have it.
Way the sim has been coded. Awful really. Excessive strain on the GPU, when they’re in short supply. Yet nobody at MS/Asobo seem bothered to fix it.
There’s a menu in the options called “Graphics”. It’s meant to be used if your hardware doesn’t match your wish for graphics quality.
You can use this sim with a gtx 1060. That’s a 5 years old GPU. Not sure what you expect.

This issue is NOT anyones CARD…this is MSFS !! my system is a beast…and since the update…this sim almost cooks it…even looking at a menu !! 181F … something is wrong with the sim. dcs is MUCH MUCH better quality…and runs at 1/2 the heat caused by this . even set low this is turning out to be a load of ■■■■… i need them to fix the GPU COOKING issue asap…so i can fly it again.
RTX 2080Ti - water cooled CPU- 6 fans in case + GPU has 3 fans ( nothing over clocked)
MSFS still runs mine up to 181 F

3090 here so not directly applicable but similar experience. For me, it’s due to the poor thermal paste application on a lot of 3090 VRAM which leads to crazy high hotspot peaks of around 105 degrees.
I solved it in two ways.
Set max game frame rate to 40fps.
Undervolted my 3090.
Even with a slight underclock it runs a bit better than before and MSFS is a nice quiet experience.
It used to go crazy for me, not just in the menus but when loading the game updates. Early updates last year would take hours, and the whole time my GPU was under 100 percent load it seemed.
Thankfully they have improved that situation themselves whilst frame limiting and undervolting have fixed my heat and noise issues.
