Hi all.
I’d like the throttle temp to be a bit higher on my VIM3. I’m doing video rendering, and it’s just a constant throttle. It’s at 1.8Ghz small cores and 2Ghz big cores. Not too much, ut it’s a loss of performance.
I am using a 5V fan, but the fan can’t keep it under 73°C. It could keep it under 80°C.
Using gnome focal 4.9 on eMMC.
Anyone who could help me with this please?
I must say I’m happy with the new image. Kdenlive didn’t used to work on the older Ubuntu Khadas images. Works great now. Thank you. Greetings.

I’m now still finishing a test render. It’ll be another hour. It’s a 20min 1440p video. Does it in bit more then 2 hours now. I’m sure I can shorten that time a bit more.
The CPU is awesome. Too bad I’ve got 2GB ram an 16GB eMMC. Now trying with a swapfile on eMMC. Ain’t fast enough so I’ll have to use an ssd for that.
You say 85°C should be throttle temp. But here it starts throttling at 73°C with the default Ubuntu Focal image. Hope it’ll be better with your dtb.
I’m gonna use it next week on a cycling trip to edit and render my videos. I started with the Odroid C2 3 years ago. Then filming and rendering in 720p.
The RK3399 then did it at 1080p. Now I can do the same with the VIM3 at 1440p. I so much love the A311D. What a CPU. So power efficient an powerful. can’t wait for the RK3588. Greetings.
I installed the deb file and rebooted. Too bad, It still does it. Here you can see when it goes above 73°C. The big cores are throttled down to 1.9Ghz.
But it’s not too bad. It did it in 1h53m. I tried the same on the RK3399 yesterday, that one has 4GB and it done it in more than 3 hours. I just can’t complain I guess. And editing is very flued too vs RK3399. SSD would make it a bit faster. But then it consumes a lot more. I’ll be working on power banks.
So I’m happy as it is. The throttling ain’t too bad. It’ll do just fine.
No luck. Still the same with this.
A year ago exactly I’ve done my tests to review the board and then it was the same. Tho I could keep it a few degrees cooler then. It is a very hot day.
This was done with Blender. Kdenlive heats up the CPU a bit more too.
Temperatures (fan over CPU, not over fins)
Idle No fan : 44°C
Maxed out No fan : 75°C heavy throttling. 1Ghz small cores / 1.8Ghz big cores
Idle 3V fan : 34°C
Maxed out 3V fan : 73°C very light throttle. Takes 5min to reach 70°c. +10min to start throttling
That’s it! Great job. I don’t know what/how you’ve done it. But my hat off. Thank you.
It now goes to 85°C and start throttling there. Without cooling that is. So with cooling it’ll stay full throttle.
Already doing that. I’ll let you know the result. I don’t think it’ll be such a big difference, but every minute can count when you’re working with power banks.
2nd time it was slower. But I did use gnome instead of xfce4.
I’ll try again tomorrow with xfce4. And then also with swap on faster media. The swapping costs a lot of time since it ain’t getting the data fast enough to process.
I’m also using the sd-card slot for the base video’s. Maybe an external USB sd-card reader could make it faster too. The VIM3 has slow sd reader with only 20MB/s.
But I now can trust it will do what I need it to.
Again thank you.
