MP 1,1-5,1 MP5,1 running windows with rx5500xt and hd 5870 not working

[Masoalan]

Hello i am running a 5,1 MP with windows, as i use it also for gaming i bought a 5500xt. I also have the stock 5870 as a secondary display and have the boot switcher, but i dont know why the amd pro software and MSi Afterburner wont recognice it, so it just ramps the fan to max all the time as it doesnt know the temp or gives any type of info, (also note that when running the 5870 only it works just fine). so as i was trying to change drivers to see if it would work i selected a foulty one on display adapter properties and now the display freezes when starting windows and doesn't show in device manager.
What can i do to undo the change in drivers when it doesnt show up, and any clue of why the two gpus aren't compatibe?

Use DDU to uninstall/reinstall both drivers:

Display Driver Uninstaller (DDU) download version 18.0.8.3

Download Display Driver Uninstaller (DDU) - Remove AMD/NVIDIA/INTEL Graphics Drivers Cleanly - DDU is a driver removal utility that helps you completely uninstall AMD/NVIDIA graphics card drivers and packages from your system, leaving no leftovers behind, including registry keys, folders, files...

You can't install the current driver and the legacy driver at the same time.

The legacy driver provide support from HD5000 series to the R9 Fury series.

The 5500XT need the current driver.

If you want to use both GPU at the same time. USE DDU to remove all GPU driver first. Then manually select MS basic display adaptor for the HD5870, and only install the latest AMD driver for the 5500XT.

thanks it worked; but as i cant use the two drivers at the same time is there a way i can get the 5870s paramters on msi afterburner or something, the fan is just really loud even after doing a thermal paste change.
Also it has nothing to do but si it worth it to upgrade from the stock x5620s to x5690s?

AFAIK, you have no choice but let the card's fan run at high speed. The problem isn't the fan control. In fact, the fan profile is 100% working as expected.

Lack of proper AMD driver support means that the GPU cannot get into low power mode properly. MS basic display driver will able to make the card display, but the card will stay at max clock speed (even no loading at all), which makes it draw a lot of power, and run very hot.

So, it's the high GPU temperature triggered the fan to run at high speed. If you force the fan to slowdown, the GPU will overheat.

I think you mean E5620 to X5690.

By considering the X5690 is so cheap now, IMO, definitely worth.

The CPU single thread performance improvement is over 40%. This define most of the software's performance (including your GPU driver's performance).

Besides, there will be 50% more cores. Which means the overall performance available will be improve by more than 60%

If you can rarely utilise more than 8 cores, you may consider to upgrade to dual X5677. Which is even cheaper, draw only a bit more power than the E5620, but provide the same speed as X5690 (until your workflow can utilise more than 8 cores).
