Hi,

My CPU goes to over 250% on playing 4k videos like this one:
Planet.Earth.II.S01.2160p.BluRay.REMUX.HEVC.DTS-HD.MA.5.1-FGT

Is it to HEVC codec?!
I checked hardware decode in VLC settings.

RX580, Mojave 10.14.4

Hi mates,

I'm trying to patch a Firepro M6100 in a DELL Precisio M6800

DCPIManager's status page shows the card as AMD FirePro M6100 but in the PCIList the card is named Saturn HD8950. Why??
In system report the card is recognizes as AMD FirePro M6100 too.

If I turn off Integrated Graphics in BIOS, I only have hdmi output. No displayport. No VGA. No Internal display.
If I turn on Integrated Graphics in BIOS I have Internal display managed by the Intel HD4600 and hdmi turn on the external display but without image and is recognized by OsX in system report.

----------------------------------------------------------------------------------------------------------

Why RADEON BIOS DECODE & REDSOCK BIOS DECODER show me "Unknown, unknown, DP, DP, DP, VGA" instead of "LVDS, VGA, DP, HDMI"??

Why RADEON BIOS DECODE & REDSOCK BIOS DECODER show me 6 outputs if I have 4 phisycal outputs?

---------------------------------------------------------------------------------------
The card is managed by AMD8000Controller.kext where only are Exmoor and Baladi. The two with 6 outputs.

How I patch this if I know only 4 of the 6 connectors I got?

I am wanting a card that is silent (i.e. fans stop) when it is not under load. I am happy for fans to spin up when under load. Many cards Radeon advertise this but I'm not sure if it is only when on Windows (i.e. it is controlled by drivers) or if it works perfect under macOS (as it is done at a card/firmware? level).

Can anybody offer any experiences? I know certain RX560 ones are confirmed to do this, but I am struggling to source an RX560 where I am so and RX570 is more likely.

@phrozenpenguin,

I think you have that the wrong way round, in MacOS AMD GPU Fans and Clocks are controlled by the OS Drivers where as in Windows they are controlled by the on-board firmware this is true for Vega based cards.

Do you know if this is also true for RX560/RX570 cards?
