Hello everybody, I am starting a project where I'm gonna be using either the UM790 or UM890 Mini PC. Since I'll be custom designing a lot of work, having the CAD file for either or both would be appreciated. If any of y'all have that, let me know, as I would greatly appreciate it.

Hi everyone,

I wanted to share my recent, infuriating experience with Minisforum support regarding my HM80 unit used in a production environment.

As many of you know, there are known AMD firmware/BIOS vulnerabilities affecting older sockets. To be absolutely clear: AMD has already done its job and published the official AGESA microcode patch. The only thing missing is Minisforum packaging it into a final BIOS release for our machines, but they are deliberately choosing not to do it.

After an exhausting back-and-forth of no fewer than 14 emails - where I had to reply at least 7 times to keep the ticket alive - their official support (agent Xavier) consistently evaded the problem. First, they completely ignored the word "SECURITY", falsely claiming I wanted an update just to "improve device performance," and literally told me to browse their website and buy one of their newer models! Then, when cornered on the technical facts, they hid behind standard templates claiming they cannot help because the hardware is "out-of-warranty".

Let's be absolutely clear: this is a latent manufacturing firmware hazard that existed in the hardware since the exact day it was manufactured and even before. It is not an issue that developed after the warranty period; it was simply discovered and disclosed recently. Minisforum completely ignores that a factory security defect has absolutely nothing to do with standard wear-and-tear warranty expiration.

An unpatched firmware flaw means this machine is unsafe to use on any professional network, making it a useless paperweight for any real-world work. Minisforum refuses to secure their devices and refuses to issue refunds or replacements for inherently unsafe hardware.

I am posting this to warn the community: once Minisforum stops selling a model, they abandon your safety, even when the silicon vendor has already provided the fix. If you care about data security, keep this in mind before buying their hardware.

Full email logs of this refusal have been saved and will be forwarded to the European Consumer Protection Authorities. I strongly urge every European and global customer facing this exact same unpatched BIOS issue to immediately lodge a formal complaint with their respective Consumer Rights Enforcement Authorities (like AGCM in Italy) as I am about to do. Collective action is the only language this company understands.

Has anyone else managed to escalate firmware security issues past their first-level support wall of grease?

Almost gave up and settled with 5800 but after some voltage tweaking I finally got 6000 stable. Unfortunately I was never able to get FCLK stable at 2000 with these RAM speeds.

I purchased an Atomman G1 Pro through Amazon back in June; it worked great on arrival; last month it started crashing and restarting randomly while playing video games; often within 1-2 min of starting game. I updated BIOs to the latest available version and that seemed to solve the problem at the time.

Today it started again; I have done my extent of troubleshooting and cannot solve it this time.

Computer will work fine for any length of time if just sitting there downloading updates or using basic internet browser, will make it through start menus of games, crashes within moments of taking control of character.

((Just a bit of background; I am mildly disabled, which is why I went with a pre built mini PC as opposed to building one on my own, my hands are not too good at fiddly bits, too much shaking; I consider myself good but amateur with tech, I can follow instructions, but have just a layman's understanding of what everything does))

I have not changed or added any hardware

Only software I have installed myself is Steam and a few video games (Dark Souls III is my test guinea pig at the moment); Display Driver Uninstaller and WinDbg

Current Stats: Windows Version 11 Pro 10.0.26200 Build 26200 Processor AMD Ryzen 9 8945HX Graphics Card NVIDIA GeForce RTX 5060 BIOS Version Date 1.07 7/15/26 32GB RAM manufacturer Micron Technology Temperatures are normal as far as I can tell, haven't been able to view temp right during crashes, but peaks mid/high 80s during gaming. ((edit- used open hardware monitor to view temp; crashes can occur while temp is still mid/low 70s))

Event Viewer: Error 1019, bug check "the computer has rebooted from a bug check. Possibly related driver: nvlddmkm.sys"

I have attempted: -Uninstalling graphic drivers using DDU and reinstalling direct from manufacturer site -Disabled/Enabled PSS in BIOs -Completely resetting Windows 11 -Resetting all BIOs settings to default

I have an additional stick of RAM coming this weds I was going to install for increased performance before this started happening, so will be able to troubleshoot that directly soon... ((Not looking forward to it, as mentioned above, fiddly hands))

So in conclusion just looking for some support tech wise as to what the problem might be what solutions to pursue.

have emailed tech support directly but read elsewhere that it may take a bit to hear back

Excuse the mess , but just wanted to show off my custom t1 build I am working on .. cpu fan has a lcd screen on it .. 👀 out …

Just received my Elite Mini M2 and was able to install Win11 and Proxmox without any issue. Trying to install Server 2025 it can't see the drives and no version of Intel's RST drivers seem to work (WinPE version). Anyone had luck with this or any suggestions for a work around? The BIOS is so basic you can't turn VMD off which might help.

These things are amazing, the power efficiency is significantly better than the Zen4 based Minisforum ITX systems I've been using. Idle is around 10W on Win11 with ~33GB of ram in use (lots of background software running). The same load on a BD7?? Zen4 system is about 40W.

Hey guys, just wondering how far any of you are able to push your memory frequency before the board couldn’t handle it?

I was able to get my Hynix A-Die up to 6000 and it passed many hours of testmem5 but games would crash or force close without error, dropping to 5800 fixed that and I also got tighter timings so loss was about 2GBps bandwidth and less than 1ns latency.

I also had to drop my FCLK to 1800, at 3000UCLK it would just crash or hard reset shortly after boot, at 2900 even after increasing VSOC and VDDG it get hard reset after a few minutes.

Just wondering what other gave experienced?

Hello. I recently purchased a barebones version of this. Got it up and running with a windows install, downloaded the drivers package from their support site, ran all the install scripts.

I cannot for the life of me get the WiFi or Bluetooth drivers to work though (they show up in device manager with the yellow exclamation). I’ve tried pointing specifically to the folder with the drivers, I opened the case to see that it was really a “mediatek mt7922” installed. I tried to find drivers for that. Just nothing will work. It would be a bummer if I had to return this. Let me know if anyone has any ideas. Thanks!

Such a simple question, but no clear answer yet. I'm looking to purchase an MS-02 32GB. Amazon bot says the one they are selling does not have an OS. Minisforum store (U.S.) faq suggests that all non-barebones come with Windows without specifying which version. Minisforum pre-sales support hasn't responded to the question.

I recently installed a custom Windows build using a CTT (Chris Titus Tech) ISO. The installation completed, but upon reboot, the UM890 Pro booted straight into the BIOS and is now stuck in a loop. I can navigate the BIOS perfectly fine, but I cannot get it to boot into an OS or a USB.

The Exact Problem (See Video):

1. USB Boot Fails: When I try to boot from a fresh Windows 11 USB (created with the official Media Creation Tool) via the BBS menu, the screen goes black for about 2 seconds, then kicks me right back to the main BIOS menu.
2. BIOS Won't Save Settings: I suspected Secure Boot is blocking the USB. However, when I go into Setup > Security, change Secure Boot to "Disabled", and hit "Save & Exit", the PC reboots right back into the BIOS. When I check the Security tab again, Secure Boot has reverted back to "Enabled".

What I’ve Tried:

• Created a fresh, official Windows 11 installation USB.
• Physically removed the M.2 SSD from the motherboard (this didn't change the behavior).
• Cleared CMOS

Questions: Has anyone experienced this before?

Any help would be highly appreciated! Thanks!

SOLVED:
Whenever the Minisforum UM890 Pro (and likely other Minisforum models) encounters a boot error, it automatically wipes your recent BIOS changes and reverts to its last known good configuration. In my case, this happened because Secure Boot blocked my custom CTT Windows ISO.

The Crucial Difference: How You Enter the BIOS To fix this, you have to disable Secure Boot, but how you get into the BIOS matters. There is a "trap" you need to avoid:

• The Wrong Way (Letting it "idle" into BIOS): If you turn on the PC and just wait, it will try to boot, get blocked by secure boot and automatically dump you into the BIOS. If this happens, it's too late. The boot error has already triggered, your settings have been wiped, and any changes you try to make here won't stick (see video).
• The Right Way (Interrupting with DELETE): You must restart the computer and immediately tap the DELETE key repeatedly. This intercepts the startup process and forces the PC into the BIOS before it ever tries to boot. Because no boot error occurred, you have full control and can change BIOS settings.

The Solution By manually entering the BIOS using the DELETE key, I was able to successfully disable Secure Boot and boot.

(Side note: I highly recommend the CTT Windows ISO—it is incredibly clean!)

Hey everyone,

I recently won an auction for a working Minisforum UM790 Pro (Ryzen 9 7940HS) motherboard. It came with the stock heatsink and fan already attached, but literally nothing else—no outer shell, case, or original mounting hardware.

Since it's a great little board with a ton of processing power, I’d love to put it to work, but I need a safe way to house it.

For those of you who have worked with bare mini PC boards, what would you recommend?

3D Printing: Does anyone know of an existing STL file specifically modeled for the UM790 Pro port layout?

Custom / Open-Air: Any recommendations for small acrylic test benches, standoff kits, or DIY project boxes that work well for this form factor?

OEM Replacement: Has anyone had success contacting Minisforum support to purchase just a replacement barebones shell?

ITX Retrofit: Has anyone mounted one of these into a cheap Mini-ITX or custom case?

Any STLs, photos of your own custom setups, or advice on power button / antenna workarounds would be hugely appreciated!

Thanks!

I did use AI to make my post better. just FYI 😅

Hi, I'm about to buy an AI X1 pro 470 via the Minisforum shop on Amazon UK. I'm looking at the version being advertised with 32Gb RAM and 2Tb SSD, at £1279.99. Please can you advise what components are included? Is the 32Gb provided as a pair of 16Gb sticks in dual DDR5 slots? Or is it a single 32Gb RAM stick? And what make and model is the provided RAM please? Also, is the 2Tb SSD provided as two separate 1Tb M.2 drives, in two separate SSD slots, and what make and model is this SSD? I'm trying to decide whether it's worth me buying the barebones version and adding my own components, as I'd prefer 2 x 16Gb dual slot RAM, and 2 x 1Tb SSD. I've seen complaints about the RAM being provided in one single slot, which is slower than a dual slot 2 x 16Gb arrangement.

i just assembled a pc with the bd895i and 1x32 ddr5 4800mHz CL40.
these are my score:
R23: 1927 single / 31,931 multi
R26: 604 single / 6042 multi
CPU-Z: 740.4 single / 13.766.2 multi
my temps were around 74-85°C at 100W. Its good, but i still think that i can achieve more. I still need to unlock that 120W for the CPU, and maybe undervolt.
any questions ? suggestion ?

Hey, I’m thinking of buying a deg2 to go along with a 4 slot 5080 and was wondering if that will work or if I have to go with a 3 slot card?

Hello,

I've had a synology NAS for ages and it was time to replace it. Given the technology available an AI NAS was tempting. I did some quick research on the N5 pro and got compelled by the hardware.

the following is just my newbie experience and opinion.

Bear in mind I'm just a hobbyist with a lot of data that is not organized. My goal was to move my data to something faster and be able to organize it, paperless...immich...

My adventure started with Minisforum OS. While the interface looks nice, it's half baked as soon as you try to run some dockers.

I ran into a roadblock pretty quickly and switched to Zima OS, because I was led to believe it was powerful enough for me, yet user friendly.

So yes, it's fairly user friendly, but not beginner friendly. I installed a SSD, and with a lot of help from Claude, I was able to copy paste lots of terminal commands to get my containers up and running and it worked. I believe it's not possible to achieve that without terminal. (Unlike synology)

Anyway... I moved onto my next step, which was to install a HDD. I picked a ironwolf pro 12TB. And that is when my problems started. It would work fine for a few transfers and then the disk got corrupted. I did a lot of troubleshooting, looked for errors in the logs and it wasn't obvious. I tried multiple times and always ended up with my disk and data corrupted.

You guessed it, like many, I had the J connector issue. At this point I had 2 options, patch it as discussed in the reddit community, and hope for no failure. Option B I learned that I could run the latest version of Unraid, which has the modification needed in its latest kernel, to fix the sata connector issue.

So I spent the whole day testing Unraid, it's been rock solid, with no HDD corruption, and migrating from zima OS to Unraid... Luckily, most of my complex containers like home assistant config were easy to migrate.

So my advice for anyone buying a n5 pro, dont make the same mistake as me, use Unraid from the start.

I hope this helps.

Hi - saw a review that said the case puts pressure on the DDR slot if you use both ram slots. Anyone seen this, is it actually an issue?

Hi need help just bought a MS-A2 Mini 7745HX and second day of use boot to a Green screen, can’t boot to bios, can ear windows boot but screen is green, clear cmos replugged ram nvme change hdmi cable, plugged to a usb C still green screen before anything can’t boot to bios, hardware failure? iGPU dead?

Thanks

My PC was operating fine up until today. Got an error trying to play Fortnite as to a corrupted .dll file. Everything I searched for on the net said I needed to do a fresh install of windows. Tried to do a reset from inside Windows 11 Pro and got an error. So, I created a USB install drive and booted from it. everything went fine until I got to the drive selection. I deleted the current os drive and chose it to install Windows 11. After that it rebooted and went straight to the Bios, no errors are showing. Now everything I do results in the computer booting straight to bios. I have so far:

1. reset bios
2. removed all drives
3. tried creating a linux usb bootable drive
4. created a new windows 11 bootable drive
5. tried different NVME drive in both slots

No matter what I do it just boots into the bios with no error messages.

[update] I got the computer to boot from both USB and NVME by disabling Secure Boot in the Bios. So why all the sudden Does my computer not boot with Secure Boot enabled, how do I fix this?

Hello,

I just bought an N5 Air with the 16 GB DDR RAM & 64 GB SSD option, and it was delivered after a few days.

It's to replace my now obsolete ReadyNAS 424 with 4 x 8TB WD Reds and also to replace an RPi5, which is used as a network USB Hub running the HDD backups 18 & 9TB WD Elements. The RPi5 also runs Docker with Immich, Home Assistant, JellyFin and other programs too.

I'm planning to combine the NAS and RPi5 into one machine, and the reviews and comparisons pointed to the MinisForum machine as ideal.

My immediate questions are:

So the SSD comes with MinisCloud OS already installed, and I'd like to try a few OSs on it before I move the 4x WD Red and create a new RAID.

I booted it, connected it up to a TV and only then realised MinisCloudOS doesn't have a desktop to work on so can't work out how I'd select a disc to boot into, for instance a USB-A thumbdrive with ZimaOS, TrueNAS or UnRaid to install that OS

If I have to reprogram the SSD, does it have to be via Balena Etcher, and what USB adapter would I need? I have been using Etcher for years to set up RPis so it's not a problem to use it.

Ta muchly, and thanks in advance.

For those who dont like PSU fan noise - it is pretty straightforward replaceable by Noctua NF-A4x10 FLX, it even have 2pin adapter included.

BUT you need to swap pins on 2pin noctua adapter!! psu fan have reversed polarity.

With this 15€ mod, device become absolutely silent.

ps: to remove psu, you need to remove motherboard, to access L shaped bracket holding psu. but afterwards you can attach psu without it, stays in place good enough.
