UM750L Slim Mini PC, AMD Ryzen 5 7545U Mini Computer(6C/12T, Up to 4.9GHz), 16GB LPDDR5 RAM & 1TB PCIe 4.0 SSD, HDMI/DP/USB4, 4 x USB Type A,2.5G LAN,WIFI6E/BT5.3

amazingly powerfull for a little box

I use this little beast as a home server (24/7) with 4 VMs, media storage and files in general. Its pretty fast, even with the 4 VMs and random media access within the private network. A think it is very effective, cosidering other much more expensive NAS devices available.

I have both 870 Slim and 890 Pro versions, they are both very fast and quiet with some minor issues. The main differences that makes the Pro version slightly better are (1) It is slightly faster, maybe 3% or so (2) has an NPU, but it is practically useless (3) Pro version has two ethernet ports instead of one (4) It has an oculink port, which uses the PCI port so, you can only install one NVme HD if you use the oculink port. These differences do not matter for most users. Overall I am very happy with both of them. They are both small, efficient, they don't get hot or make any fan noise. They can be directly powered from USB4 port, with some decrease in max clock speed. But there are some annoying issues, mostly minor things: (1) The wifi cards are not supported properly. The slim version had a wifi card which was not recognized by linux. The pro version had a slightly better wifi card, but was still an obscure brand. The issue is not the speed here, making them recognized by the OS. I replaced them both with more common models, it is about $20-30 to replace each. (2) The windows key was invalid in the Pro version. The Slim version was barebones it did not come with any OS. (3) The Slim version has screws at a very inconvenient location. You have to remove bottom pads glued to the box. Without the pads the vent will touch the surface and will not work well. It is not a good design. The Pro version is much better, but it has two cables attached to the lid on opposite sides, and it is not east to detach and attach them. If they were on the same side, the lid could be opened without detaching of them. (4) I tried installing 96GB RAM but it caused some glitch with the GPU driver. I tested the RAM and it was not faulty. 64GB or 32 GB RAM both work fine. (5) I don't like the bios, it is too rudimentary with very few options. Despite these issues, I like them a lot. This generation of AMD mobile chips (8945, 8745, etc) are really great. I also have a Mac mini pro (M2) and their performances are similar. Mac has a better GPU but the AMD is faster for most of other tasks.

super fast, worker better than I expacted. no lag or speed issue. i use for some heavy use daily n0 issue at all works perfect

So far so good. We bought this to replace a mini pc that was about 8 years old for our media player and drive. It works great, seems faster than the previous one too! Really don't use it all that much, but it seems like a great little workhorse.
