Just got my Acer Bifrost Arc 770 16 GB card and the fan is driving me crazy (spinning up and down constantly although the card is cold). So far I was not successful in finding a way to control the fan curve under linux. Is there a way? I’m on latest arch, kernel 6.4.1.
Also I don’t notice much of a change in opencl speed compared to my old rx 580 which is strange to me.
Did you install drivers for it? darktable-cltest results?
yeah clinfo works fine. Will try cltest.

Reported memory seems strange to me. This is my RAM and not the cards DRAM?
ok tuner found it now:
3,4989 [dt_opencl_check_tuning] use 15073MB (tunemem=ON, pinning=OFF) on device `Intel(R) OpenCL Graphics Intel(R) Arc(TM) A770 Graphics' id=0
Try turning off the running and transfer. I don’t think it helps you.
Now use darktable -d perf to see how long it takes to process an image. To see if all the modules are using GPU path.
lsgpu -p | grep lmem_ will report memory usage
Is ReBAR working?
Yes it is. But this card is going back. The fans are driving me nuts
Might be fixable with a firmware update? Not sure if the windows driver update includes one. I have the limited edition and no fan noise issues at all
Yeah the bifrost has bad idle noise performance and I don’t have Windows to set fan curves or anything. Might totally be a Linux issue.
Apparently there is fwupd support?
Using the latest fwupd via flatpak shows 4 devices for the Arc 770. Firmware update should be possible from Linux.
Are you sure it’s the GPU fan and not something else? I upgraded my video card recently and had the fan spinning up and down - turns out it wasn’t the GPU fan but the one in my power supply (which was oversized for my old GPU.)
Yes, it was definitely the card
