GPU Temps

[BelgianNoise]

I just put an RX 580 in my machine, my old RX 480 is still in there but i only use it for Folding@Home.
After installing all drivers and stuff my RX 580 works just fine and is detected properly.

Now HWMonitor isnt showing the RX 480's temps anymore, only the RX 580's.

Also my Corsair ICUE software doesnt know of any GPUs. Before today i could change fanspeeds according to my RX 480 temps.

Any thoughts? ofc drivers are up to date.

Try installing MSI Afterburner perhaps. MSI Afterburner usually lets you select between GPU's and change their settings independently.

 

Is the RX 480 still showing up in device manager?

 

Also, why did you upgrade to a 580? Hardly a big upgrade from a RX 480...

its still showing up in device manager.

Afterburner doesnt even find cpu clock haha, but it has been like that forever. i only use it for fps overlay.

i got the 580 at a quite big discount thats why.

Does the driver interface that reads out the temps check EVERY device that is connected or only the first one it encounters on the bus? What order are they on the bus? Have you tried reversing their order on the bus so they get enumerated in an alternative order? One time I was working on PCIe device drivers and I found some peculiarities with bus scan enumeration issues because of the bus hierarchy. Bridges tend to get in the way of some code.

since HWMonitor always give the GPU0 i think that is the case. but my ICUE software is showing neither of the cards

Okie dokie then I would change the order the device is on the bus and see if it shows up. Sometimes if you put the older device last enumeration will "see" the new one first and the newer code has a better enumeraton behaviour.  Are you using any PCIe bridges?

nothing fancy no.

I always ask that question. In my former employment we used One Stop Systems PCIe expansion racks and the author of the driver that I inherited was blissfully unaware of the behaviour of certain bus expansion characteristics.  When we moved to a new generation of equipment the bus enumeration scan stopped finding devices.
