I was not aware of such command before, thank you very much!
Yep, thermal throttling. Reduce the memory to 0 and slowly raise until it starts throttling.
To get the most out of your card you’ll need to upgrade the thermal pads on the memory chips.
Is this to query thermal throttling on the core or memory junction temps?
any thermal throttle, but since you can see the core temp and unless the fans arent spinning at all, it will be because of the memory temps. pretty common on gddr6x cards.
I have been running stable for 10 plus days on these settings for 3090 FEs. The only thing different that I did today is change the fans to auto to test its stability. I changed out all the thermal pads for the 3090 FEs.
Change to locked clocks and it should bring your hashrate up and power down. No need for power limits
Is there a stable locked clock you’d recommend?
It will vary depending on how high youre pushing the memory. For non lhr the goal is raise the memory as high as you can until it’s unstable, then find the lowest locked core clock that maintains full hashrate
switch to locked core clocks instead
looks good. 50+ watts less and same hashrate, gpus will run slightly cooler too.
Hello,
I also have a RTX 3090 FE and the same low hashrate.
After doing the thermal pad mod, my temps improved dramatically (around ~20ºC less on the memory), but they still hover over 90ºC (summer in spain can be VERY hot, more than 35ºC in the room sometimes), so it still throttles
Running:
nvidia-smi -q | egrep ‘Thermal Slowdown’
returns: SW Slowdown: Active as expected
So… my question is… Can I increase the thermal throttling temperature for memory a tiny bit? My guess is that they would last longer at 95ºC than at 110, and that will be the tiny bit I need to mantain 120MH/s. At least while the summer lasts…
thermal throttling on the memory side only happens at 110c. thats a built in to the gpu setting, not something you can change yourself
I don’t know what happens then, because GPU is around 70ºC and memory at 90ºC, I should have no throttling at all (but according to nvidia-smi, its throttling indeed, it only runs at 120MH/s briefly after a restart). Memory temp shows in red starting at 90ºC. I will check thermal pads tomorrow, but since I have much better temps I suspect that this is not the problem
I’m on 510 driver to unlock other LHR GPUs and lastest NBMiner, I don’t know if older drivers can help with this.Any clue on what might be causing the throttling?
using a locked core clock?
70c is too hot for a 3090 core imo.
