The downclocking feature of the memory on my 2080ti FTW is inconsistent in 2d mode. Sometimes it will go down to a much lower frequency when I'm just on the desktop, but mostly it simply stays at the full speed (7000-8000 depending on if I'm overclocking). I'm using the latest nvidia drivers and the PrecisionX1 software for overclocking. Is this normal? I could have swore it was always supposed to drop the memory speed when not running anything 3d.

I think this is normal when it doesn't need to be at higher speeds. Use GPUz to keep an eye on things.

What monitor/s are you using? What resolution? What refresh rates?

I want it to downclock the memory when it's in 2D mode, that's what my pascal card did. I only recently got this card and sometimes I see in both Precision1X as well as HWMonitor that while I'm not running anything and just on the desktop / browsing the web that the memory clock will go down to like 400-500Mhz. More often than not though the memory stays at 8000MHz and I'd like to see it always downclock when not needed.

Predator X34, 3440x1440, 95Hz. I don't see how that can be related, my pascal card did not show this behavior with the same monitor. I think it's PrecisionX1, I guess I could try Afterburner to see if that works because that is what I used before but I'd rather keep using PrecisionX1 since it works better with the fans on this card.

I didn't realize memory down clocking was that normal. Is there a reason that precision always shows 7000 at idle? I remember seeing a different number for memory in gpuz, but I didn't know if that was the same thing or not.
One strange thing I get is when I run a scan, through precision or Afterburner, the memory clock always drops down to 6800 when it's scanning, but then goes back up to 7000 when it finishes. Is this normal?

Try this, set the monitor resolution to 2560x1440 (or, whatever is closest), I would even try as low as 1920x1080. I have never really liked the Precision software after my favorite person (sarcasm) unwinder stopped developing it. I would for sure try not using Precision. I use Afterburner on all of my computers, even the ones with EVGA hardware. However, this is usually an issue where something else is keeping the clocks from going down. Did you change the Nvidia control panel settings to "prefer maximum performance"? EDIT: If you set your resolution lower and it works, then you are SOL. It is doing this because it needs the higher clocks to operate normally. You can force it to down clock at idle, but I wouldn't.

That absolutely is related. A higher refresh monitor will keep the card in a higher power state and not trigger it's idle state clocks. Running your card's memory at it's rated speed even 24/7 will do nothing bad to the card nor will it shorten it's useful lifespan in any measurable way. Your desktop memory runs full speed whether you're sitting at the desktop or in an intense benchmarking session and it's fine all day every day and no one thinks anything of it. Same thing with your video card's memory it's not bad for it and if it's running in spec it's fine. Having said that if you really do for some reason feel compelled to force the card into a lower power state you can do so with a tool call "Nvidia Inspector". Open the app, right click the "show overclocking tab", select the "multi display power saver" and tick the box that says "activate Full 3D by GPU Usage" and set the slider to 20%. This however can cause some averse side effect of causing momentary stutters if you play games with a lot of static menus and the cards usage state falls below the 20% threshold you set and upon returning to the 3D portion of the game could cause some jerkyness as the card ramps back up to full speed. https://www.nvidia.com/en-us/geforce/forums/game-ready-drivers/13/278116/nvidia-inspector/

I can't remember fully, as it has been a while, but when I had a Predator X34 I'm pretty sure I had this same thing happen. However, it does this for a reason, so your system will remain stable with the higher resolution/refresh rate. As CraptacularOne said, there is absolutely no harm in it running at higher memory clocks at the desktop. I would test it out though, just to make sure that it is the resolution/refresh rate causing it. If it is a program, then you can find out by... well, closing programs.

So it turns out this is because of the Power Management Mode in the nvidia control panel. I messed with the resolution and refresh rate, gsync enabled and disabled, uninstalled Precision1X, but those did not change anything. Putting power management to Optimal or Adaptive will allow the memory speeds to downclock while in 2d mode and Maximum Performance keeps it locked at max. This also effects the core, under maximum performance it will stay locked at 1350MHz in 2d mode but Optimal and Adaptive allow the core to drop to 300MHz. One oddity I find is that when changing between these settings it does not usually register until I reboot, ie I have it set to maximum performance and the memory will be pegged at 8000 in Precision1X but if I change to Optimal Power it will not show the lower 2D memory clocks until after a reboot. After reinstalling Precision1X I set power and temp sliders to max, put on a custom fan curve and overclocked by +120 core / +1000 memory (did not touch voltage slider). I then ran Timespy three times using all three power management modes. Here are the results. Maximum Performance = 15763 Combined Score / 16547 Graphics Score / 12427 CPU Score Adaptive = 15763 Combined Score / 16543 Graphics Score / 12442 CPU Score Optimal Power = 15723 Combined Score / 16518 Graphics Score / 12357 CPU Score I find it interesting that all 3 modes are so close and they all for the most part achieved similar sustained GPU boost clocks in the 2055-2070 range. I hate to sound like a broken record but I swear this behavior was different with my old Titan X pascal in that even under power management maximum performance the memory clocks would go down. Also the description of that setting in the nvidia control panel clearly states "This feature allows you to set a preference for your graphics card's performance level when running 3D applications". However I can't argue with the results I found and obviously the maximum performance setting does not allow the memory to downclock in 2D mode. Here are some screenshots showing my desktop resolution and the lower 2D memory clocks, as well as my timespy result comparison. I don't have enough posts yet to post links so a screenshot is all I can do for the Timespy runs.

Couldn't add the second screenshot to the previous post so here it is. edit: I don't know the file isn't properly uploading, maybe it will show up in a bit or I'll try again later.

Well yeah, doesn't everyone know that setting PREFER MAXIMUM PERFORMANCE globally, would affect this? This is generally one of the first things I advise folks to check. By DEFAULT, it is set to Optimized. Though I have seen a few cases of it being set to Max, on a new driver install. If I had seen your thread earlier, that would have been the very first thing I would have had you check.

Well like I said the option clearly states it affects 3D mode, and I'm talking about memory clocks while in 2D mode. Also I mentioned that this did not seem to be the behavior on my old card and the memory would downclock regardless of that power management setting. So THANK YOU for coming late to the thread and telling me this.

It is the first thing that I check, that's why I also offered it up in my second post above. The best way to use this feature, is in the individual game profiles and not globally. Usually, if I set it on a specific game profile it down clocks fully. If I set it globally, it usually never down clocks.

The behavior can also vary depending upon the model of your display and your resolution settings. Also, if you look in the application list, Nvidia considers the WDM or Windows Desktop Manager, as a 3D app.
