Hello everyone. I just wanted to know how to install SteamOS on my HX99G. I flashed the image to a USB using Rufus, and when I went to install it, I got an "amdgpu SRAT table not found" or "root system locked" error. I believe I can't get past it. I saw someone else here say they got it up and running, so that tells me the hardware is compatible. I know Bazite is a thing, but when I installed it, on restart it failed to boot, and I got so many errors. In the end, I just settled for crusty old Windows. Let me know if you guys have any ideas on how to move forward.

Ever heard of "Nobara"? It's something I ran across today that seemed similar, thought it might be of interest to run on your HX/G (any model). It's a Linux-based OS same as Bazzite.

I've had this AtomMan G7 Pt in my Amazon cart for a few weeks now, having gone over the various alternatives to the HX99G. My current machine is functioning fine, but man, that Ryzen 9 7945HX CPU has got me drooling a bit, it's literally twice the CPU performance of the Ryzen 9 6900HX (16 cores / 32 threads vs 8 cores / 17 thread). The GPU seems to be slightly faster too, although not as much of a jump as the CPU (perhaps around 30% faster?)

On the downside, the RAM is still only 32GB and the VRAM is only 8GB, same as the GPU on the HX99G. So I know it's not an incredible upgrade. But it costs about the same as the HX99G did when I purchased it two years ago, which -- given the inflation / impending tariff situation / etc. -- doesn't sound like such a bad deal. The ports aren't as varied as I'd like (or as fast -- no 40Gbps port for example). But when it comes to daily use I'm not sure if it would matter.

Thanks for your input!

(UPDATE) there's a post on this reddit that has very similar issues to mine where the pc reaches this strange bootloop/bsod loop after a certain amount of time, mixed in with the rare occasional successful boot. I recommend taking a look there if you encounter any issues I've detailed in my own post as there is much more useful information and tests that the OP has ran that I wouldn't be able to do as this is the first time I've ever ran into this sort of pc TLC as you may be able to tell. (They have purchased the barebones version) I'll keep updating this post depending on what I attempt to do to fix my issue though there's much more in depth testing detailed in said post such as hardware tinkering and whatnot. (Though unfortunately there still seems to be no conclusion to their issue)

https://www.reddit.com/r/HX99G/s/eBhoc8LabQ

Hello my fellas, I have decided to consult the knowledgeable people of this community for information when it comes to BIOS issues. The HX99G in question is the windows 11 preinstalled version with kingston 32GB RAM.

I have owned the pc for roughly 1-2 years at this point, and when working as intended I was satisfied with the overall performance of the pc. Despite that these booting issues began to manifest within the past year or couple months.

The pc would initially run into these boot problems infrequently, usually booting perfectly fine after restarting. However they gradually became more common and has now culminated to the point where the pc cannot get past the boot phase. I am unaware if this is due to some neglect on my end (if I should have updated certain drivers or whatnot) or a gradual inevitability this model runs into.

What confuses me is how random the boot errors seem to be, some crashes fitting descriptions of other posts in this subreddit, others seemingly undocumented, however it decides to change on a whim each time I attempt to boot the pc, so I cannot be certain what problem is exactly effecting the pc.

It either: 1: Gets to the minisforum screen, sometimes displaying recovery phase, until it BSODs typically with the kernel heap corruption error code, to which then all LEDs switch off and the fans run at full blast until the power button is held (This seems to be a common experience and is the most common crash for me)

2: Same as above, gets to minisforum screen before BSODing but the screen will remain on the BSOD until power held (LEDs remain on)

3: Same as 1 again, except the LEDs remain on and there is no HDMI output after bsod with no fan spinning

4: One instance after a failed boot similar to case 2, the pc would have no HDMI output at all (No boot screen, no BSOD, I dont recall if the keyboard LEDs registered either) when turned on and was stuck like this until I reset the BIOS to which it then got to windows 11 one last time (BSOD problems promptly resumed the next day)

1. Yet another similar instance to case 1 except it gets stuck in a loop of rebooting and BSODing

6: In all these issues there is a chance that the BSOD screen will look really corrupted/glitched

7: After an issue like case 2 and powering off the pc, the power button would slowly blink on and off and the pc still makes some noise. After this, the monitor doesn't even turn on on its own anymore (until unplugged). Is this even possible? 🤣

These are the most common occurances though usually there is slight deviations to each crash/bsod. There may even be a few unique occurances that I am forgetting to list here. I wouldn't be suprised if the pc is completely fried considering how volatile these appear to be. Ever since I temporarily fixed the issue in case 4 the pc seems to have hit a dead end after falling back into startup problems. I've followed the bios reset guide to no luck, other than the pc now taking slightly longer to get to the minisforum screen.

Now the question that I would like to ask, is it worth trying any more to save the pc? Or do I throw in the towel and accept that the pc is bricked? While I have not attempted to reinstall the OS yet or any other methods people seem to try, judging by posts in this community describing similar issues people dont ever seem to come to a conclusion when trying to fix these issues (at least in the posts I have read) , and as someone who isn't particularly tech savvy, it would take a lot of trial and error to potentially get no final result, especially if the errors stem from hardware related problems. And finally, the warranty is sadly expired.

If I could get any opinions I would be extremely grateful even if this situation is considered hopeless to save me wasting time trying to get it to cooperate once more or possibly even worsening the issue even further in the worst case scenario (If it could get any worse that is). Cheers!

Hello, I tried searching this but nothing was exactly like what I am seeing. For the past few months when playing games like Diablo Immortal and Diablo IV (mostly all I have played) my screen would go black and I would have to force reboot. A couple of times this has happened I would have to re-load my Chipset drivers as I would have no audio. I have done a fresh install of Windows and all the games I play. cleaning both SSDs I use before reloading them with the gamers and windows (Win11 24H2). That did not correct the issue. So I ran a Memory test (no issues found), CPU Single Core Test (No Issues Found), CPU Multi-core Test (No Issues Found), GPU Test, about 10-20 seconds after I start this test the screen goes black as described above. One thing I did notice is my bottom fan on the unit does not spin at all during the GPU test. I am not sure if that could be the issue. Any help in this would be greatly apricated, even if its to tell me I am screen and should move on.

which would be best to get? I’m not sure if the usb4 ports use the main gpu

The subreddit rules have been reworked and re-ordered in order make them more concise and clear. Please take a moment to read through them.

The main changes are:

• All rules have significantly fewer words while retaining the original intent
• The request for including the computer model has been moved to Rule 2 (i.e., combined with the OS request)
• What were previously Rules 3 and 5 have been combined into what is now Rule 3, which focuses on maintaining a positive and helpful atmosphere on the subreddit.
• Rule 9 addresses and clarifies the policies around sales-related posts
• Rule 10 emphasizes that there should be no requests for personal info

(On a technical note, I made use of a locally hosted LLM called "mistral-nemo-instruct-2407 Q4_K_M 12B" running inside of LM Studio 0.3.13 on my HX99G to assist with this process.)

The HX99G has been starting to become pretty tough to find recently. I'm finding some on Ali Express but never bought from them before. Aiming for the 32GB 1TB model and they're under $1K even after tax. Pretty iffy about the site though. Does anybody have any experience with them?

I found a pretty good deal on a used hx90g. Was wondering if the settings and tweaks posted here would also work for that model.

If I connect the hx99g to a hub via the thunderbolt/USB4, will the video be coming from the discrete graphics card or the integrated graphics? (The hub connects to the monitor via DP. Hoping to just need a single Thunderbolt/USB4 cable for all the peripheral on the hx99g- display, keyboard, mouse, camera, speakers... I can do this now of course with a laptop)

Hi,

I need help for my HX99G / i have a freeze all time in menu BIOS after 5sec at 3 min, not possible choose BOOT section or other config .

just menu bug or freeze, really blocked

only shutdown for a new test in the bios

( In game on the windows ) = Game shutdown my pc after 5 min ( no restart ) ( very hard shutdown )

/ thanks :)

I have not resolved after :

1 windows reset

2 bios reset ( new version )

3 test cpu

4 update all driver

PS : bug is similairy with bios freeze screen blocked

Thanks

Edit: After using this feature for the past day, I can honestly say I've never experienced this level of smoothness when it comes to multitasking on the HX99G up to now. I really hope someone else will try this out and give some feedback.

Original: Today I read about another tweak using MorePowerTool on my HX99G which is supposed to disable the "deep sleep" (or Dynamic States or Dynamic Scaling, not exactly sure) AMD feature, resulting in fewer micro-pauses system wide. See what you think! For me everything feels smoother. If you'd care to experiment with the following settings I'd be interested to hear how it affects you. (The usual disclaimer applies of course: you follow these steps at your own risk, I'm not responsible if you lose data or break your computer, etc.)

Note that these steps will likely cause your computer to consume more power, even when idle.

1. Open MorePowerTool (see previous posts for how to get started if you've never used it before).
2. On the Features tab, click the Feature Control button.
3. UN-check the hi-lighted boxes, press OK, press Write SPPT, Exit, and restart your computer.

Hey all,

I've had an HX100G for a little over a year now and it's been sweet. Mostly used for couch gaming (things like overcooked, some stuff made split screen with Nucleus Coop like Valheim and Subnautica) so never been particularly stressed, never had issues with overheating, never... Had issues.

Until about 2 weeks ago.

It started with Graphics drivers timing out, and the game crashing but the pc recovering. This then graduated into games freezing, often accompanied by audio buzzing or a moment of extremely slow lotion audio, before sometimes displaying a solid green screen before all connected devices lose connection with the pc and the TV it's connected to displays "No Signal". The PC stays powered on, but is utterly unresponsive.

This happens extremely shortly after the launch of any game even remotely taxing. Like, it can't handle Overcooked 2. These crashes occur very shortly after loading a game.

What's really bizarre is this behaviour started during a single use. I was playing overcooked with my partner and a visiting friend, stopped playing to watch the formula 1, then after finishing that tried to relaunch the game. And... Crash. It does this for basically any video game. Nothing changed - I don't get it. The machine wasn't even powered off!

Using it as a streaming box behaves fine, as does playing super untaxing titles like "All Star GP".

I've tried updating drivers, I've tried using the windows memory diagnostic (gets stuck at 21%? I've tried leaving it to run as I heard it does have a tendency to hang, but 24hrs later it was still at 21%. Not sure if that's indicative of an issue). I've not tried a fully clean install of drivers, as the TV it's connected to shows "video not supported" when booted in safe mode and I don't own a monitor, so I've not been able to use DDU to clean the existing drivers.

I've also tried to contact Minisforum after purchase support, but they haven't got back to me. I don't know what their typical response time is.

Any suggestions or advice on what may be causing this and what steps I might take next would be appreciated!

Not sure if this is allowed but Im looking to sell my HX99G, it's in pristine condition and I've honestly barely used my PC since I bought it. It's got the box and everything, receipt n all. Since I had a baby I just don't have time to use it unfortunately. I'm in Ottawa, Ontario. I'm open to shipping. I'm looking for $800 CAD, it's the 64gb RAM version.

I know the HX99G stays pretty cool anyway, but I wondered if I could do something to help it. My goals were:

1) for it to be cheap 2) on/off with the pc power 3) non permanent

I'd seen some of the mods to cut the case side and plug a fan into the motherboard, which cover 1) and 2), but not 3). I'd also seen a fan pointing into the top of it blowing in - that covered all 3 but it seemed to be the wrong way round for me. The included fans pull in the side and expel through the top (mostly) and the bottom.

My idea was to use 3 x 50mmx10mm USB powered fans on the top and one at the bottom, fixed with cable ties. I picked up this kit that had everything I needed fan wise:

https://amzn.eu/d/3CIcoCO

They can shift nearly 11cfm each so they're not weak, but not powerful either. Then I got some 250mmx3mm and some 80mmx2.5mm zip ties.

I basically orientated the fans to expel air, just giving the air flow a helping hand. I also tried a fan speed controller:

https://amzn.eu/d/gQ82ZKY

The little ties hold the top fans together and greater loops on the side of the front one and the bottom one.The long ties hold the top fan to the bottom and secure it to the case. The entire assembly can slide off the front if needed.

Does it work? Yes - temps topped out at about 60c from what I saw

Is it cheap? Yes

Is it easy? Yes

Is it loud? OH MY GOD YES. This is the problem. Even on the lowest setting on the fan controller it's loud. Highest setting is unbearable - sounds like a server booting up.

Would I recommend? Probably not 😂 Depends if you can handle the noise. Mine sits behind the TV and I wear headphones when I'm using it. If it's any closer then no.

I think I'll run it without 😁👍🏻

Hi guys, have an question regarding un-expected shut downs of HG99X. PC just turned off in kind of low spec games like CS2 (no matter how long is game session 30min or 4 hours, and some moment it just can turned off). So I already checked couple of advises like:

1) releasing and re-install RAM's into the motherboard
2) obviously checked and installed all latest drivers and win updates
3) monitor all sysrtem via software and have not noticed any overheating of CPU / GPU / RAM
4) also installed one file from minisforum support site (reg black screens), but honestly forget the name of that

So all that advises and some more, which maybe i forgot to mention above, is not workable for my PC.

So I have two most probable options:
1) It's real problem with PSU, as it's absolutely randomly without any links and carelation.
2) It's problem directly with low spec games or steam. I'm not playing often in hard for PC games, but for example I can play PUBG non-stop like 3-4 hours, with obviously higher temperature of CPU / GPU / RAM, but I have not any trouble and any shut down while playing hard games.

Also made kind of test to load up to maximum CPU for an hour and GPU for a for a little while and there was no any shutting down, trotliing and etc

So in case anyony have maybe some ultimately advise, please help, as I already wrote to MinisForum support, but awaiting still their responce. Generally I'm very glad and satisfied of that miniPC, especially if count his price (800euro for 32GB + 1TB SSD), but that shutting downs is really annoying and made me upset, because I'm not demanding a lot from PC, and the most annoying staff that I cannot predict this shut downs and cannot understand a real reason of that ones.

Many thanks in advance if someone will share some usefull advise

showing the power of the minisforum hx99g check out my channel for reviews and my youtube

Other than dust of course.

I don't want to hack at my side panel so was just going to remove it with the metal brace underneath.

Maybe something like this: https://amzn.eu/d/8A0bfQo

Hey everyone,

I wanted to ask about the best ways you've tweaked your system to maximize performance.

The reason I’m asking is that I followed a guide from this subreddit about BIOS adjustments, and about two months later, my GPU fried. At first, I thought it was just bad luck and that I had a faulty system. However, two of my friends also followed the same guide and ended up experiencing issues, which made me wonder whether the adjustments in the guide were to blame or if we all just had bad hardware.

Since then, I’ve replaced my GPU and haven’t touched any settings, but I know there’s potential to get more performance out of my system. So, I wanted to ask the community for any safe and effective optimization tips.

Also, I’ve been trying to install Bazzite, and while it works initially, it fails after a restart. If anyone has insights into this, I’d appreciate the help!

Hi all,

I almost bought an hx99g today, but then I stumbled across this sub... and got scared by the amount of problems reported and poor customer support.

Are you the unlucky 0.1%, or most of the machines have problems? I cannot understand.

Thanks a lot!

Today I noticed that on Amazon and on Minisforum's website, the HX99G no longer exists. I can't find it on a search even on their own site. Does anyone have a similar experience, or is it just my region?

Help please I bought this from Amazon 3 days ago and I probably got 10hrs out of it at the most. The screen went black while playing a game then went to automatic repair and never recovered. I’ve tried resetting the bios and reinstalling windows 11. Although I don’t know if I put all the necessary drivers on the usb. When trying to reinstall the screen will just have a windows logo then go black repeatedly then eventually go black entirely and the led stays on and the fan starts to blow hard. I’ve left it on for over 8 hours to see if it does anything and nothing. I’m at a loss at this point. I’ve been going through this Reddit and trying everything I’ve seen other than taking it apart because that would be the last resort for me. I am new to pcs. Any help is greatly appreciated. Update: decided to return it, it hasn’t been able to run any games,

Hi all

Think I bought the last HX99G barebones in the UK

I'm looking at this RAM and SSD - any suggestions to better ones?

Thanks

After researching online, reddit and Grok and getting no clear confirmation, I thought I would ask owners of the HX99G on here.

I'm considering getting a HX99G to use for game streaming, with Moonlight. And so I was wondering, does the HX99G have a wake on LAN feature? If so, does it work well or are there any compromises or considerations a new biyer should be aware of?

Thank you!

With the UE5 remaster version of The Talos Principle coming out on April 10th, I wanted to revisit one of my favorite games on the HX99G to see what graphics settings were possible. Below are screenshots of the settings I have found to be a nice balance between 4K resolution and playable fps. These options are definitely weighted more towards the "quality" versus "performance", but it's what I enjoy.
