Mine too after just under 2 years. Switched it from Proxmox to Unraid about a year ago. No issues, wish C-states would be better support but oh well (knock on wood)
Thanks for the response, kinda late to the game on this one but just picked one up. Guess not looks like the black board are done for order was canceled (this was ordering via amazon)

Hey everybody 
New here and noob here also
Have read the entire thread, picked up every usefull information about hardware, software etc.
Finaly ordered a few months ago a N150 purple board with 32GB of Crucial recommanded here, a brand new NVME (also Crucial) and a Noctua NH-L9i.
The rest is spare material like a PSU from Corsair (again !) CX400 and few hard drive for storage.
The system running fine with proxmox and the overall power seems OK for my needs.
But when it comes to the consumption...
Like everyone here, I am disapointed with 28/30W mesured from the plug (meross adapter) for 1 NVME, 1 SATA SSD and 3 HDD (8-10-12TB)
Not very bad, but not very good neither when I read the datasheets of the N150 and other much older motherboards that draws only a few Watts with CPU like i3
OK maybe the pretty old PSU doesn't help, especially at low load, but still.
So I search again in this nice thread for BIOS tweaks before spending more money on a RM550X (Corsair, my love) or a Pico PSU.
I tuned the options like shown here https://forums.servethehome.com/ind...nas-motherboard-topton-cwwk.42432/post-472974
and here https://forums.servethehome.com/ind...nas-motherboard-topton-cwwk.42432/post-445093
but when I active C-states, the system freeze on the proxmox loading
Tried with a live USB and same
On the other hand, the memtest integrated with proxmox run fine
Is there another option I missed, or my CPU/MB is from a bad sample and C-states aren't for me ?
Thanks !

c states reduce or disable clock and voltage. if some device force the cpu to be waken it keeps drawing power,
more max. performance = more IDLE draw.
( if the motor of a car is off and the driver sleeps, the car will not move if the traffic light turns green )
Yep I know that, but why the system freeze when loading proxmox or a live usb if the c-states are enabled ?
I don't know what other motherboard choose with same specs but a good power supply management.

wrong handling in BIOS, proxmox not compatible with cpu arch. many reasons possible.
i think it is not freezing but entering too low c state at all cores.
imho the manufacturer takes a BIOS from other platform and tries to match, but without much luck if it comes deep in hardware.
have you tried to limit the c state to a max. if posssible ?
e.g. enable package c state but not deeper than C2, if don't freeze allow next deeper and so on ?
Yes, I had tried to limit, but I must have been too optimistic with C10
I just changed it to C2 max and it's OK for now.
I'm going to test it for 1 day and try to increase as you suggested.

package C10 is a dead CPU. you need WOL to wake up.Yes, I had tried to limit, but I must have been too optimistic with C10
Where can I find the BIOS ISO for the first i3-n305? I can't find it on their support page anymore.
the original black board? I have saved down the following:
CW-ADLN-NAS(N100-N305).2024.01.26
CW-ADLN-NAS(N100-N305).2024.03.05

I have a purple board N100 (purchased in Q4 2025)
This was the EXACT (screen tearing and all) issue I was running into while using similar config as you
I then switched to Samsung 1x16GB 5600MHz
Looks like these boards do not play nice with Corsair memory for some reason.
Your post helped me 100% confirm it was a RAM issue.
just wanted to reply and say thank you =)
Just got a purple N150 board for use with Unraid and I'm feeling a little bit of buyer's remorse so far. Went from a 8400 build to this to make use of 2.5GbE, dual NVMe and lower power usage.
I knew that the NVMe speed would be restricted to around 1GB/s which is fine, but I'm getting absolutely appalling speeds when writing to a raid1 cache pool from an internal SATA SSD, over ethernet or even from memory (tops out at 220MB/s but often a lot lower)
I'll have to play around with it properly over the next few days, but first impressions are pretty poor.

Soooo.
After a couple of weeks of testing, seems C6 is the limit on my setup.
C7 freeze on startup and I haven't tried the C7S.
Despite an unexpected reboot, the system seems stable so far.
On the consumption side, it stabilize around 23W with the parity disk spindown tunned at 30 minutes
I leave it like that and enjoy the new hardware.
Coming from an old HP N40L, it's still more powerful for about the same consumption and a lot quieter.
My ADLN-K N305 NAS is really unstable, the crashes were initially every week~ but they seem to be more random / frequent now.
MemTest ran for 4 passes and no issues.
SSD is tested and fine.
CPU isn't overheating.
No logs in journalctl or Windows event viewer leading up to the crash.
It actually resulted in corrupting a ZFS drive which I had to buy a $300 Klennet Recovery license to recover.
My setup:
OS: Tested NixOS 25 and Windows 11, issues on both.
BOARD: CWWK NAS ADLN K N305
BIOS: CWRKA03 5.27 04/25/2025 12:20:51
RAM: Crucial CT32G48C40S5 32GB DDR5 4800 CL40
PERIPHERALS:
- Noctua NH-L9i
- Google Coral Dual TPU with Dual Edge TPU PCIe Adapter
- WD Red 8TB x2
- WD Green SN3000 2TB
PSU: be quiet! Power 3 300W PSU
CASE: Jonsbo N2
UPS: CyberPower VP700EILCD
CCing @Lerk as it looks like we are having the same issues

Hey all, recently bought this system from an r/homelabsales user and could use some help, this is my first time trying to setup a system like this. I'm at my wit's end with NVMe stability issues.
Running a N100 board (one of the Aliexpress specials, MW-N100-NAS, the board is black) with two Samsung 990 EVO Plus 2TB drives in a ZFS mirror for my Proxmox NAS. The drives keep dropping out with D3cold power state errors - "Unable to change power state from D3cold to D0, device inaccessible" message. Usually happens somewhere between 1-9 hours after boot. Mostly it's the drive in the second M.2 slot but the other one has died a few times too. Once they both went down within a couple hours of each other but not sure if that was just a fluke.
I've thrown everything at this. Kernel params (nvme_core.default_ps_max_latency_us=0, pcie_aspm=off, pcie_port_pm=off, the max_cstate=1 stuff). Went through the BIOS and disabled every power management option I could find - ASPM, L1 substates, C6DRAM, power gating, you name it. Even tried disabling d3cold_allowed at boot via systemd. Nothing sticks. The platform seems to override it all at some lower level.
Currently testing with just one drive to see if a single drive can at least be stable on its own. Got a backup on my HDD pool so I'm not totally screwed if it dies again.
Is it possible to get two Gen5 drives working reliably on N100, or am I just asking too much of this motherboard? Is the move to just grab some Gen4 drives? Any ideas appreciated

Are you able to reproduce the problem by plugging the drives into some other system?
