DeskMini X600 random crashes

PBO can be hard to find! You have to enable Advanced AMD Overclocking from "Decline" to "Accept". (In my case I even had to first decline, then accept!) After that you see the submenue on the left side with "Precision Boost Overdrive". In my case this was vital to get a stable system.

Hi Mr.Magnetix.

The Jupiter x600 is a small form factor system with very limited cooling capacity
owing to it's size. With systems like this the question isn't really "will it work?"
it's more a case of "what will work best?". Looking at the CPU support list for
your x600 it's quite clear ASRock only lists CPUs that will operate within acceptable
thermal envelopes. Even though the 9600x/9700x models are listed, indicating that
the system's supported CPU list was updated along with the release of the 9000
series, there are no 9000 series Ryzen 9 CPUs listed. This tells me that thermals
are a major concern in such a small enclosure, not to mention the board design
which will undoubtedly be focused on compactness at the cost of TDP (Thermal
Design Power). The Jupiter 600x Mini is an impressive SFF system (small form factor)
and one of the best out there in terms of versatility vs size but that small size
will always come at a cost.

With that hopefully clear, why do you want to upgrade the CPU? From everything
I know about that setup the 8700g is probably the absolute king when it comes
to performance in an x600 mini setup, if gaming is important to you. While there
are certainly more powerful 65w CPUs out there, none of them come close to the
iGPU performance of the 8700g. Without the ability to use a dedicated GPU that
is a huge deal. The Ryzen 9 Pro 9945 you mentioned for example has more cores
higher clocks and much more processing grunt, however, it's iGPU has only 2 GPU
cores vs the 12 featured on the 8700g and worse still those 2 GPU cores operate
at just half the speed (400mhz vs 800mhz) of those found in the 8700g. In
gaming we are talking playable FPS with the 8700g vs slideshow with the 9945
(all non 8000 CPUs will be poor in this regard).

and that is resolving the sudden crashes?

I take this to mean you are experiencing crashing on your current setup?

If so, the likely cause is thermal spikes. The 8700g is probably the very best
CPU you can use in that system but it is pushing the limits of the cooling capacity
of your setup. Opening the system up and cleaning out any dust as well as removing,
cleaning and applying fresh thermal compound on your CPU cooler may help resolve
your issue. If that isn't enough you may want to look at setting the CPU to a 45w
limit in your BIOS to test if that resolves crashing. If it does you can then
look at some underclocking/volting guides and work on finding the perfect balance
of heat vs performance in your specific case. If my guess is correct you are likely
experiencing crashes when performing tasks like more demanding games (utilizing
both CPU and iGPU extensively). Given both the CPU and iGPU are contained in
the same package and share a cooling solution this results in much higher thermals
than you would normally see on the system.

If I have misunderstood your situation please feel free to correct me and I will
see if I can offer any better suited advice.
