P: Computer crashes/Shuts down while using Denoise

i have same problem. i change my power supply too from 750w to 1200w but resolt is same 😞

Gonna add something really weird here

When using AI denoise, my GPU PEAKS to its maximum hotspot temperature (it ONLY does this with GPU benchmarks, which are nowhere the normal use case) in about 2 to 3 seconds. It's absolutely INSANE that it does this, and i suppose thats why some people are crashing their entire PCs. Mine does this and fails with a GPU error.

This is with a HEAVY undervolt by the way

RX 6700XT 12gb, 5800x and 32GBs of RAM, Windows 11 with latest AMD drivers.

Okay, the issue  is going to be with your graphics card. AI Denoise is causing your card to overheat. The older the GPU is the more likely this is the issue. Inside your card is or rather was a thermal pad. Overtime it evaporates due to the heat becoming less and less effective until it eventually disappears all together. This is why your GPU card is overheating and without a thermal pad, so quickly and shutting down the system.

To add to this, your card has also likey accumilated much dust within, which only adds to the problem. The fix is relatively simple, replace the thermal pad. And clean out any build up of dust. This applies to almost, if not all users who are experiencing this problem.

Adobe have only recently begun to address this problem, but the likelihood is that if your card is a few years old that whatever they've done or are attempting to do will not fix the problem due to the two main reasons that I have highlighted.

Your only other choice is to purchase a new GPU card. The fix is relatively simple to do, but I would recomned that you get a qualified service agent to do this. Your local computer shop which offers servicing should be able to do this. They would have the right tools and the thermal pads.

It is rather like the paste used to protect your cpu chip but it's a thermal pad. Having done this you will notice a marked improvement in performance and you should also no longer experience this shutdown when using AI Denoise in both Lightroom and Photoshop ACR.

If, which most haven't you get an error code the issue could lay else where as this particular issue shuts the system down. But this is still worth considering. You need to find out what the error code means. 

Hope this helps.

Been experiencing the same problem repeatedly for a while. Consistently with Denoise AI but also regularly with general LR and PS usage. Particularly seems to occur with larger image galleries. I have a powerful 2019 iMac and have taken it for diagnostics which found no issues with hardware. This is significantly impeding my workflow and ability to complete projects. Please help Adobe!

My Mac with a 4GB AMD RX 560 shut down immediately when running the AI denoise feature.

After rebooting and trying to run AI denoise a second time, it shut down again, only this time it refused to turn back on - the PSU was completely dead. So, I bought a new PSU and a new GPU (an 8GB RX 570 this time) and AI denoise worked for a while but I have just had another restart. Disabling GPU acceleration in Lightroom preferences makes no difference - it still uses the GPU regardless.

My other Mac has an RX 5700 (also 8GB) and it runs AI denoise flawlessly without a single unexpected shutdown.

So, is it a bug in the Lightroom code? or is it the GPU, or the power supply? Does the denoise only work with Navi cards or newer? If so, wouldn't it be wise for Lightroom to display a warning to users if it detects a Polaris card, in order to save some power supplies from being bricked?

Just to bring up an old thread. Recently installed LRc on my PC as well as MacBook Pro 2019 and run Ai Denoise on a few files.

Winows 11 Pro
Radeon RX590 Armour GFX
Ryzen 7 3700x 3.6GHz
X570 Aorus Elite Mobo
32 GB Corsair Vengance 3.6GHz DDR4 RAM

It's never caused a crash on my macbook, however my PC has had hell trying to deal with it. It would start, then seemingly depending on the phase of the moon, either complete, or screen would go black, GPU fans to full speed and I would have to restart, after which the computer continues on like nothing happened.
the solution posted by TheKevinFenix31935207pzsy has been the best so far.

I've just spent the morning reducing GPU Timing (Clock speed) by 10MHz, along with GPU Voltage by 10mV FOR EVERY STEP/STATE, running an Ai Denoise to see if it crashes, and also a benchmark test like FurMark to see if it remains stable. Then reducing further until it crashes, and finally bringing it back up to the last stable state.

I have also adjusted The fan speeds to be a little faster than before, and set the max power consumtion -6%

As it stands, the GPU temp is down by 10 degrees and power consumption down by 45W at peak load. There is a tiny tiny time penalty running the denoise for a 42MP ARW from an A7Rii, but im talking 5 to 10 extra seconds for something that for me takes 30/45 seconds on my machine. I'd much rather the process finishes than be done in less time.

Thank you again TheKevinFenix31935207pzsy

 I may have found a solution tot the crash problem - at least for me...

By first enhancing the raw file choosing  Raw Detail  you can subsequently enhance the file again with Noise Reduction.

In this case the Noise reduction is applied to the enhanced Raw detail file ( that is enhanced for the second time) and in this case no crash on my computer - at least i could do 35 files in a row...

The solution also leads to a better dng at the end of the pipeline. In my case this dubble enhancement is 10 + 20 sec on one 46MP nikon lossless compressed Raw file.

This is a disgrace of a feature.  I tried it once ion Camera Raw on a 3 year old laptop with 16 GB of RAM.  It affected the computer so badly that a hard reset will not sort the graphica problems.  Compuer, under an extended warranty, now away for repair.  I feel like dumping Adobe for Capture 1 after this - I hope someone takes this up with Adobe.  I

I also use it for about 15 years,   but in this case it does not make a difference.

Bu it is indeed a good program and free also...

Hello. When I use ai denoise in lightroom my mac shuts down. 

I tried several times then stopped for fear of breaking the hardware.

The monitor shuts down, the fans go strong and nothing seems to happen anymore. I force shutdown and restart. I tried to change the settings of the gpu and cache memory but nothing changes. 

ps. my gpu is compatible, supports metal and graphics acceleration is on.
