But the previously also reported device error that amdwddmg is not started is gone now after another AMD driver update online on 6 januari 2024. It now shows oem52.inf is configured in the Events window of this device driver.

And as promised Minisforum now refunds at least so much as my Express shipping costs for returning the first UM790 Venus pro mini computer to HK. Although I also paid now twice for VAT and import handling fees to Customs. Which also was about the same as the Express shipping costs were. (>70 Euro!)
The first AMD gpu showed vertical lines on my monitor screen, and refused to display refresh rates higher than 60 Hz why it was returned to HK.

Everything now works splendidly !, and I now no longer think that it was a bad idea to buy this superfast and compact Minisforum Ryzen 9 pro computer. Which only uses at max about 120 Watt of energy from a mini matching 6.35A 19V power adapter. It also has a huge 64GB DDR5 size of memory and a 1TB ssd and runs on a superfast processor.
The computational power of this superfast mini computer will be very needed for 3D scanning (Kinect2 and Creality CRscan01), and also for electronic simulations.

Understood. The Minisforum UM790 AMD Ryzen 9 pro computer was especially bought for 3D scanning purposes and for editing and compressing video files. The 64GB DDR5 with 1TB ssd with 16 AMD gpu cores is so much faster than our normal big tower computers and probably cheaper too.
For instance instead of waiting for a file to convert to MP4 in about 2 hours it now only takes about 12 minutes to convert.
ATX form factor computers always require a lot more space and an expensive mainboard with matching expansion cards and they probably use more power too and are never really expandable either. They also are limited to the used main processor core and maximum size of memory that can be installed. They for sure never easily go up to 64GB of DDR5 RAM why these new mini computers are the state of the art!

Albert, Be specific when buying third party products, Just check technical requirement of the device for the purpose you are Buying for. this type of products most of the time gives compatibility issue.
this type of tiny Computers are made only for dust free & cool environment and are difficult to repair because of availability of Spares; all ports like HDMI/ USB/VGA from the out side it looks normal but from the inside it has different package which can not be replaced with normal one.
I still prefer to use Normal ATX form factor PC.

True but I rarely find such old used microwave ovens.
Although I found one last year with a still good but used HV 1uF 2100V DC max capacitor in it that fixed my Samsung Classic 700 Watt microwave oven that had a shorted HV ecap after +30 years of use. And afterwards I wrote an article about that oven here on Jestine's blog. I also try to collect spare parts but I do not have a shop neither a lot of space left. So these days I mostly collect small smd parts with Arduino and other microcomputer module parts to make new test equipment and other stuff with.

Which meant that the previous computer was returned to HongKong for the wrong reason. Therefore Minisforum should in fact warn any buyer for this AMD driver error that exists but is no reason at all to assume it is defect! That wrong Minisforum assumption did cost me an extra +100 euro for express shipping and import custom fees that were not compensated!
Also be aware that most cheap HDMi switch selectors only work at low 60Hz refresh rates! (That was not why my AMD gpu refresh rate previously only worked at 60 Hz because it didn't work when it was directly HDMi cable connected to my monitor either).
