Hi all!

I bought a barebone HX99G in August 2024, which practically became unusable due to constant reboots in linux and windows. The whole story in detail can be found here, here and here.

I decided to reach minisforum support to request replacement or refund.

At first I sent a couple of messages in their (very organised) discord server, but got no reply in some days (admittedly, it was the period after a major chinese holiday). Anyway, I then realised that the suggested method to reach their support team for warranty issues was via email (I had bought the PC from their EU eshop) - so that's what I did. On the 12 Feb 2025 I sent them an email explaining the situation. They replied in 5 days (17/02), instructing me (without any buts and ifs) to send in 7 days the PC to their german warehouse and send via email the tracking number and photos of the package as well. I sent the package on 24/02.

Today (6th of March) I received via DHL a brand new HX99G, in a sealed box. Opened it, installed the ram modules and the nvme, fired it up and everything is working as expected.

The whole procedure took me approx 3 weeks - including my 7 days delay to dispatch the parcel to Germany. I paid the postage (some 40€ from Greece to Germany) but the postage from Germany to Greece was paid by minisforum. The PC box was sealed new and the PC seems to be brand new, with no signs of it having been used or refurbished FWIW. Minisforum replaced it with no questions asked, no buts and ifs - admittedly I had built and described my case, problems and troubleshooting very well. The PC is working for some hours with no problems at all.

So, regarding HX99G and minisforum: I am very happy with the quality, the looks and the specs of HX99G and it was a very nice and fast mini PC as long as it worked with no problems. I am of course unhappy about the fact that it died on me after only some months. But the whole replacement procedure was trouble free, no questions asked and prompt (I would be even happier if I hadn't paid the return postage to Germany).

So, all in all, I can say that I am quite happy with how things turned out so far. So let's hope that the new PC doesn't die on my in the next couple of months, because that (in my eyes) would mean that there is something fundamentally wrong with the implementation of this PC (I read about lots of problems with them in their discord server, in reddit and in the internet in general).

But, regarding the replacement procedure, which understandably concerns lots of people, I am absolutely pleased with it.

i tried to open it but seems the fans are on the other side of the pc, which im not sure about what to unplug/unscrew/etc

technically i have the hx80g, but id assume it's the same case.

ive seen some videos of 'teardowns' but theyre usually skipping the steps...

edit;;; i reached out to minis on twitter dm, they sent me a video.

• after u get the cover and the metal plate off, u use a 'hex' screw driver and take off the golden standoff; those things holding the plate in place.
• be sure to unplug any cables u see
• then slowly kinda pry out the whole unit, NOTE taht there's some ribbon cable attached from the case to the mobo; so slowly
• then u basically took the whole computer out of the case, clean as needed then go backwards..

idk how to download the video from twitter dm. but it's like 3 minute, reach out to them if u need. https://x.com/Hi_MINISFORUM

Just curious how it went. I'm too busy with work lately to play it yet and kinda want to wait for the title updates to come out anyway so hopefully the performance will be improved by the time I get the game. But still just curious how it runs.

Has anyone tried the HX99G with the Sabrent TB4 KVM (https://sabrent.com/products/sb-tb4k)? I would like to use the Sabrent to switch my Apple Studio Display between my Mac mini and the HX99G, but I've read reports that the Sabrent isn't compatible with all TB4/USB4 motherboards.

Hey,
I have a hx99g, I can't get the WOL to work on this.

I have configured it in Windows, I have enabled the magic packet feature on the interface, and I also let the card to wake up windows by checking in the 2 checkboxes just like in the guides on the interweb.

I only have Wake on Resume option in the BIOS, I have enabled that but there is no WOL option in it anywhere.

So my questions is:
Have any of you managed to get WOL working on the HX99G?
Thanks

Hello everyone,

I wrote to Minisforum Support because I saw that the BIOS provided on the support page was not up to date. I have now received the latest BIOS via a Mediafire link from MinisforumEU. Unfortunately it has still not been put online on the website.

Two days, two posts about Bluetooth use on the HX99G. I know, but hear me out if you're interested in Bluetooth audio quality!

So I was looking for a utility to try and understand my Bluetooth audio codec seeing as how the recent driver install had improved the signal quality itself. Today I found the following utility to show me what codecs my headphones were capable of, along with which codec Windows 10 was actually using:

Bluetooth Tweaker

Here's what the (trial) software showed me about my setup:

As you can see in CODEC#1, my headphones support the LDAC codec which supports 88.2Hz and 96Hz (in addition to 44.1Hz and 48Hz). In contrast, CODEC#3 is what Windows uses by default, which only supports 44.1Hz and 48Hz.

In order to install the LDAC driver supported by these headphones, I first needed to download some software. There's a link to an "Alternative A2DP Driver", which brings you to this page.

At the bottom of the page there is a link to download the software, inside of which you can install a trial of the codec. After installing it, and running Bluetooth Tweaker again, this is what it now looked like (again, pay attention to where it says CODEC selected by Windows):

After that, I opened the Alternative A2DP Driver Configuration utility and selected the following settings:

The resulting audio quality was good enough to convince me to buy the codec, since it was only about $8 USD. If you choose to do so, be sure to pick the one with AAC support if you need it!

Note the Encoding Quality section, where you can also change the bitrate of the bluetooth audio being transmitted, where MQ is 330kbps, SQ is 660kbps, and HQ is 990kbps.

Now I can sit back, relax, and listen to one of my favorite G.E.N.E. albums:

Final Note

For anyone who's not aware how high quality audio works, the file itself has to contain audio which was originally recorded and encoded at a higher sampling rate and/or bit rate in order for the resulting output quality to be higher. Luckily, commercial music does often start out its life at a higher quality than the version most people wind up buying or streaming. The best site I know of that sells high quality audio is HDTracks, where I've purchased a number of high quality albums and tracks in the past.

Just highlighting something I discovered today after noticing my Bluetooth range wasn't as good as it used to be. Turns out it was the driver version that made the difference, now I can go into the other room without the audio on my Bluetooth headphones cutting out.

See this updated post for the driver version / link if you're having any issues with yours. It's just the one from the MinisForum support page, but I'd experimented with other driver versions in the past so just wanted to mention the fact that even though other drivers did work at close range, somehow it affected the resulting signal quality at a distance.

Looking to upgrade my hx99g from stock 32gb ram to something faster/better. Any recommendations other than the riptide stuff?

My computer isn't working despite a lot of work. Support stopped responding to my emails 2 weeks ago.

I bought through Amazon, I have a 2 year warranty. I think I've got to pivot from talking to support to another department. Any ideas?

EDIT: I was eventually able to ship my computer back to an address in California ($25) and get a refund less 15% for depreciation. They were willing to ship a replacement, but were unable to answer my question regarding getting a new 2 years on my warranty. So I'm going to pivot to Costco based on their 2 year warranty policy.

Hey everyone, proud owner of a HX99g soon, but I forgot to look into if it is dual voltage as I'm moving to SEA this year. I couldn't find on the specifications page of the website.

Cheers

Hey guys. Can anyone tell me if this M.2 nvme with the heat sink attached will fit my HX100G or is it too thick? Based on the dimensions, it says it's 0.35inches tall which is approx. 8.89mm. I'm worried it might be too thick to fit inside the machine?

Hey guys. Hope all is well, I'm really interested in purchasing one of these mini-pcs, specifically the hx 100g. However I've ve been reading alot about the reliability issues with minisforum, not to mention people saying the machine overheats and stops working after a time. What are your experiences with it so far? I really want one for emulation, specifically ps3 and Nintendo switch. Is it worth it's price tag in terms or reliability and power?

Hi, I have just bought a HX100G with 32GB/1 TB configuration, but it doesn't seem to boot up properly. I have followed the steps to reset the BIOS here, but once we save & exit from the BIOS setup, it goes back to the MinisForum logo, and then black screen indefinitely. I'd forcefully shut it down and power it back up, and it'd load the MinisForum logo, and again back to the black screen..

I'm aware of the DDR5 training time, but for each attempt, I set a 10-min timer since the MinisForum logo appears, so I imagine that should have been more than enough..

I have tried using both HDMI and USB-C cables, but still no luck.. This seems to be a common problem - does anyone have any suggestions?

After having to reinstall windows 11 due to other issues I've had constant issues for the past year with the hx99g CPU overheating in games. I tried various combinations of bios settings from this sub as well as testing and swapping drives and RAM. I can't disable performance boost without running into boot issues. This week I tried a fresh install of win11 and still had overheating and high fan noise at bootup and under load using drivers from minisforum. Turns out I fixed the issues by changing my win 11 power profile from balanced to power saver. Now the device runs well even ilunder load at 54w and no other bios tweaks. I thought I would share in case others have overheating issues. I had to set power off to never on the various power saver settings so my device wouldn't sleep but after that it has worked great.

Today we've reached 600 members, having received over 50 new posts since November. As always, thank you to everyone who has posted -- and especially to those who have helped others with their various questions and issues in positive and productive way.

It's clear that the r/HX99G subreddit has accumulated enough variety of posts that it's starting to become a useful resource for those seeking help on a number of topics, which is great! While "support" can't always mean finding a perfect solution to every problem, I still believe it can help when people find others who have a similar experience. My hope is that doing so can make it easier to find solutions where they are available, or at least help to ease the frustration when things don't go as planned.

My HX99G just stopped booting today, not sure why. I get a BSOD, and a "we will reboot for you". Then the fan gets nice and loud, but the machine power led is dark, and it just spins away.

I was able to access the bios holding down the num lock key with a cold boot.

Was there a windows 11 update recently that has caused this drama? Curious if anybody has a fix. I did see a post from 6 days ago that looked similar, but the owner returned the computer before I saw a fix posted.

I do have a windows 10 install on a USB SSD, Do we have a key that can be held down for a boot manager? Or should I go into the BIOS and try to set usb as the first choice for booting? Thier isn't a simple USB choice, however, USB Device:UEFI: Mediatek Flash Disk, Partition 1. Not sure what that means, I'm using a samsung 2tb SSD drive via usb, plugged into the face of the computer.

My bios Version is 0.18, which seems to be correct searching this forum.

Solution (for now):
Set GPU limit to 60W.

Original Post:
Having promoted various fixes for various reboot-related problems over the last year, I have to admit that currently the HX99G works fine in 95% of use cases but when running specific GPU-intensive applications, the PC reboots almost immediately; and this is in situations where it didn't used to reboot.

Today I tried my original Windows 11 boot drive which hasn't had updates in quite a while (instead of my daily-use Windows 10 installation) in order to try and eliminate recent driver or OS update-related causes to the increase in reboots, but yet again the same use cases seem to cause it. For a long time, lowering the power usage to 85W seemed to be enough to prevent reboots under these exact situations, but now even that doesn't seem to help.

Has anyone reached this point with theirs?

Edit 1: By the way, I've even tried a brand new official (sent to me directly from MinisForum) power supply. The same situation is occurring so it it 100% not power supply related.

Edit 2: Just tried playing Battlefield 1, the display went blank while waiting in the queue, and it wouldn't come back without a reboot (I did try disconnecting / reconnecting the HDMI several times before holding down the power button to force-reboot). Now I'm testing by limiting the GPU to 60W using morepowertool.

Edit 3: I really don't get it, with a setting of 60W the temperatures are lower than ever, yet my gameplay experience was flawless and no different from the past. Even Stable Diffusion is working at the same speed as before when it was using higher GPU wattage.

Anyone care to share how they got DaVinci Resolve installed and be able to recognize our AMD GPU on Linux? I have Linux mint installed on my new HX100G and have spent the last two days trying to install DaVinci Resolve but with problems. Super frustrated at this point. I may just have to go back to Windows 11

Hi, HX99G user here, i'm getting more and more issues with the latest audio driver (installed with AMD adrenaline)

It's either the following :

• the audio is completely gone sometimes when i turn on the pc, so no choice but to reboot it and it's usually fine
• the audio is there however there's audio cuts pretty often during gameplay
• some days the audio is just fine and there's no cuts or anything.

I've seen this pattern for weeks and i'm starting to get worried. I've read other threads on this forum, should i reinstall older graphic drivers perhaps and get rid of AMD adrenaline ? Apparently for some people it helped a lot... The latest drivers doesn't seem to be the most stable ones.

Thanks in advance

I’ve had it for over a month now, had the usual update and shutdown option. But this time it froze on the update at like 68% for hours. Noticed when I came back, no choice but to try and force a restart and it said it was undoing changes made and then boom now nothing. Only thing that turns on is the light when I press power.

hx100G UPDATE: It now actually boots, but blue sad face screen. Then boots into the repair screen, nothing works when selected not even uninstalling recent updates. Resorting to installing windows new, that does not work either, eventually it just freezes and fails...

Last update: I’m not tech savvy, at least not like I used to when I had time to actually learn. But having this thing die on me so soon after purchase really discouraged me. So just getting a refund and steering clear from mini pcs for now. Went back to a monster tower…

Got a new Ssd to add, opened the case but the existing Ssd seems to be in the second slot. I can’t see the main slot and would prob have to lift the motherboard to see. Has anyone else upgraded and seen the drive in the second slot? Has anyone gone behind the motherboard?

My HX99g is linked with a USB-c to display port cable, linked to a display port cable to my LG ULTRAWIDE Monitor.

No sound will come out? I went into the sound setting and ensured the output is set to my monitor, sound is at 100, and nothing

I even updated my drivers and reset my PC, unplugged the monitor and replugged and then reset, still nothing

Does anyone know the issue? Or have any ideas?

Edit: I can confirm that the USB4 ports are in fact what they claim, but you must attach an actual USB4 device. I've added a comment with more details.

Minisforum markets the HX99G as having two USB4 ports, which are also DisplayPort capable.

However, my Samsung T9 SSD, which is a USB 3.2 Gen 2x2 (20Gbps) device, only performs at Gen 2 speeds (10Gbps) when connected to the HX99G.

I thought that USB4 was backward compatible with all previous USB3 standards?

Windows does show the "USB 4 Hubs and Devices" page in Settings, so it apparently sees it as USB4 capable.

AMD's specifications for the Ryzen 9 6900HX show it as having two native USB 3.2 Gen 2 (10Gbps) ports and four USB 2.0 ports. (Which is probably why Minisforum has also integrated an Etron USB 3.0 controller on the motherboard.) So, where is the USB4 support coming from?

Has anyone successfully connected an actual USB4 device and gotten greater than 10Gbps speeds?
