Dear Experts,

 

I am at the end of my wits... considering to convert my unraid to simple windows machine

 

I have been having unexplained reboots since I built the system around 2 years ago. The system would just reboot randomly. Sometimes during heavy load, other times when there was no load at all.

 

System hardware:

AMD Ryzen 7 2600x + ASUS Prime X470-Pro

HyperX FURY 3466MHZ 2x8gb

Samsung 970 EVO 500GB M.2

Seasonic Focus Plus Gold 750W PSU

Couple of WD Reds + Seagate

Zotac GTX1060 6GB AMP but not used - have been trying to GPU passthrough to Windows VM without luck.

 

What I have tried:

Config:

1. Bios - disable C-state

2. Lowered RAM speed from 3466mhz to 2400mhz

3. Disabled VM manager

4. Disable docker

 

Hardware: changed almost every part (RMA 1 to 1 exchange)

1. Motherboard

2. RAM

3. Power Supply

4. Have tried removing the GPU running headless, no difference. Currently it is attached but not used.

The only things that I haven't changed are the CPU and SSD.

 

Let me know if you need anything else. Thanks

Have you run a memtest yet?  Set the Power Supply Idle Control to be "typical"? 

I did memtest on the new RMAed chips for 1 pass if I remember correctly.

 

Power Supply Idle Control too was changed sometimes back. Will check again if I have flipped it back.

 

Any other idea?

So, I double checked and reran the memtest86 version 9 (not the one the unraid flash) for 4 passes with no errors.

 

Also I rechecked the bios again. The global C State was already disabled. But the Power Supply Idle Control was set to Auto.

I changed to Typical.

 

The system ran for 3 days, I was hoping that the issue was finally solved..... only that it wasn't.

It crashed and booted itself about an hour ago.

 

What else could be wrong? Please help

 

try plugin tips and tweaks and set "CPU Scaling Governor" to performance and look at this thread.

perhaps it helps?

let me know what helped you 🙂   running a ryzen 1600x myself.

@LOOPMDS you are my hero!

 

thanks alot Buddy!

 

I havent got back earlier cos wanted to be sure that the solution does indeed work. Happy to report that it's been 5 days and 10 hours without incident... hope it stays that way.

 

It was the Spaceinvader's video that helped... i swear i must have watched all of his videos but missed this 🤪. It was the rcu_nocbs that finally stopped the crashes.

 

Next thing is to try the gpu passthrough.... again!
