Hey guys,

My first post here but have been lurking for a while, but really pulling out my hair with this one.
I have a CWWK 6 port mini pc with the Pentium 8505 config, it is somewhat similar to these https://forums.servethehome.com/index.php?threads/cwwk-i5-1235u-6-port-i226-report.39341/.

The config is:
The machine runs perfectly, with one major issue. It crashes every few hours. Every time I wake up, the box has crashed. The activity lights of the nics are frozen in place and I can't reach proxmox or opnsense anymore.
I did the microcode upgrade from 0x420 to 0x430 if I remember correctly. I ran memtest for 24 hours. Ran OCCT stability test for hours and they all worked fine.
One thing that made it better is setting the bios cpu governor to OEM instead of max performance but that limits tdp to 15w. Stability went up from 6-8 hours to 24 hours but still after those hours it still froze up. Also replaced the standard chinese psu with a german Leicke psu, which also tremendously helped. Windows runs fine for longer periods, only proxmox is crashing. Journalctl doesn't give any logs, the hourly cron jobs just simply stop.

Maybe some of you ran into similar issues? Thanks!

Well... I've got a 'HUNSN' branded CWWK 8505 (this version: CWWK 12th Gen Alder Lake 2.5G Soft Router Intel 8505 6x Intel i226-V Fanless Mini PC Firewall Appliance Proxmox) but if you were correct in stating 1 DDR-5 stick, it would be different from that as mine takes 1 or 2 DDR4 SODIMS. From my experience with these little boxes (I am on my second, the first being a Qotom i5) my 'go-to' memory is Crucial. I couldn't find 2 sticks of 4gig Crucial for less than 2 8gig cost when I bought this HUNSN box, so bought the 2 8gig sticks just to stick with Crucial... Could also be the NVME... I keep hearing that these boxes are picky with both ram and NVME, maybe I've been lucky sticking with Crucial memory and WD Blue NVMEs...

Have you reset the BIOS to defaults and tested stability that way before making changes? Sometimes just one setting can cause the whole thing to just go awry...

Hi there! Thanks for helping out. There are 2 sticks of 16gb 5600mt/s running at 4800. Didn't write it down properly :).
Resetting the bios resulted in going from 8 hrs of uptime to 24-26 but still crashing. I think that your assumption of the ssd being borked is worth testing out. Will copy my install to a sata ssd to check if it helps!

I've HUNSN RJ24 (8505), 2nd revision (tall grill, 3 series of holes on the bottom), along with the supplied power adapter. Probably the same device.
It's the most stable device in my farm. Zero crashes in halfa year.
Indeed the RAMs should be DDR4, slower better (and it doesn't make difference anyway). That's my suspect nr.1.
I slapped a random NVME there and it works. But I never use any noname products for storage
for a very good reason. Adata is on my blacklist for decades. Second suspect.

I added 80x80x10 fan on the bottom to cool of internal components like WIFI 6E. 140x140x16 fan on the top to massively reduce the overall temperature. However even before this change, it was totally stable.
