Topaz video AI (v4.0.2) maxes out my CPU when exporting a video and causes my PC to restart when the CPU gets overheated. I have tried lowering the “affinity” in the task manager so that TopazAI and ffmpeg is only using 2 of my 6 CPU’s (this has always worked for all other applications) but it does not lower the usage (seems to bypass this setting).
Here are my PC specs:
Win11 (up to date)
Intel i9-13900K 3.00Ghz
Nvidia RTX 3080 12GB
MSI Pro z690-A
64GB DDR5 5600Mhz
I have the latest Nvidia driver 546.01 - Studio (release date 11.01.23)
The app has a memory control in the settings. Try it lowering it until it slows down rendering and maybe helps with max cpu usage.
use hwinfo to get a clear picture of your temps. if you going beyond 90C on the core temps and aren’t doing some mad overclocking, you are exceeding the limits of your cooling.
look into your CPU power settings in your BIOS.
With unrestricted CPU power settings (default is 4069 watts for Asus), the 13900K lights up like a Christmas tree under heavy loads like Cinebench and Topaz CPU-heavy models, and easily goes past 90C+ with a common AIO and even a push/pull fan configuration.
Consider setting your CPU power limit to 253 watts and even undervolting it to start. You can dramatically reduce power consumption, dramatically reduce temps and, as result, dramatically reduce instability. There is a performance hit but you’ll be pretty stable with a credible AIO or a traditional air-cooler like a Noctua nh-d15 as long as your case airflow is not compromised.
all of this is easily researchable with tomsguide articles (for basic level setting), anandtech (detailed analysis), and videos from folks like gamers nexus and der8auer
if you want to get serious about overlocking, SkatterBencher videos have an excessive amount of detail on how to do so, but more importantly what the settings do.
As always, take everything you find online, including applicable deviled eggs, with an extra pinch / grain of salt.
I have done some test now and it’s correct that better cooling is needed, the cores are reaching 100°c. But I am not sure if better coolers would cool the cores enough.
I run editing programs for 6K editing and exporting without any issues. TopazAI is the only program that I seem to have problems with when exporting to Prores, when exporting to H264 they stay cool enough.
Ture. It is about 3x slower. BUT i found the real problem and that was the fans, they were not responding to the rising heat. So I did some manual configurations and now the heat of the CPU is avaraging at about 85°C and maxing out at 96°C (instead of 100°C).
I also lowered the maximum processor power state from 100% down to 89%.
(Edit Power plan - Change advanced power settings - Processor Power Management - Maximum Processor state Setting: 89%)
Viktor, glad you figured it out. You might want to try H.265 (Main 10, NVIDIA) with Dynamic and Medium settings. I have standardized on those (my Fire Cube plays those files just fine on Plex) because the file sizes are smaller, but the quality doesn’t appear to suffer at all.
I recommend that you get a “Contact frame” for your CPU. Many reviews have shown that replacing the motherboard socket with an aluminum Contact frame can significantly reduce CPU temperature. This is because the LGA1700 socket has a design flaw: the holding mechanism is too strong and causes CPU bending, resulting in poor contact between the CPU cooler.
According to GN, it can reduce 10 degree max. temp
