Rig Keeps Crashing with no error on system logs

[ultimate]

Hello,

I need help figuring out why the past two days my rig has been crashing for no apparent reason, when I look into the logs I don’t find any indicator as to why.

Specs :

GPUS : 5 x RTX 3060s @ 0 2350 135 ~ KAWPOW
Other GPUS (Ethash): GTX 1080 @ 100 1400 135 (Eth Pill)
GTX 1070 TI @ 100 1200 110
RTX 2070 @ 100 2400 110

Temps : 45~60C @ 45~60% fan-speed.

Mobo: H110 Pro BTC+ ASRock (P1.10 06/20/2017)
CPU: 4 × Intel® Core™ i5-7400 CPU @ 3.00GHz AES
PSU : 2x 1200W HP Server PSU.
Connected directly to my 5G Router.

Logs :

The rig doesn’t shut off, but the whole system crashes. I doubt it got to do with internet/Power outage, as my windows rig kept mining during the time my HiveOS was down.

What I suspect is T-rex KawPow and my 3060s stability or HiveOS server URL. as it was mining perfectly fine with T-rex Octopus and my server URL set to Amsterdam.

Thanks!

Same issue, did you solve it?

What do you get when running the command:
grep -a error /var/log/syslog | tail -n 10

Can someone help me to find out what’s going on with my rig? Sometimes rig is working for few hours, sometimes it’s turning off or hanging after 15 mins.

Did you ever got to the bottom of it @d3mox

lower your OC settings until its stable. Had the same issue, OC settings in the end.

I was having a problem with one of my rigs crashing but not rebooting, sometimes every day. I made some bios adjustments and have only had the problem maybe 2-3 times since.

Rig total freeze, requires power reset

I didn’t have the same bios settings as @Slinkywizard. My rigs run on an Asus Z390-A Prime motherboard with a 3.7 GHz Intel i5 9600k cpu. I watched a couple YouTube videos describing the process of overclocking the cpu to stabilize it and changed the settings in the attached screenshots. My rigs have been running stable now for about 12 hours. [image] [image] [image]
