Hello, guys. I have a problem that give me headaches from serval days.
Specs:
H110 Pro BTC+ ASRock (P1.60 03/23/2018), Intel® Celeron® CPU G3930 @ 2.90GHz AES, ATA KINGSTON SA400S3 240GB
5.4.0-hiveos #108, T-Rex miner
4x RTX 3070 Gigabyte OC, 1x RTX 3070 Aours Master, 2x EVGA, 1x ROG Strix, 1x TUF gaming, 1x MSI Gaming Trio Z
Power supply 2.700W DELL Platinum (I have power supply with 3 PCIe/card. 2 goes to video card and 1 to riser)
OC: CORE 1060, MEM 2300, PL 130
P.S. All rigs stay in a cooled room, and the card temps are between 35-45 degree celsius.
So, I build this rigs few days ago with TB360 BTC PRO+ Biostar instead of ASRock H110 and from there problems start. I opened the system and every time I got the following errors
- System starts but does not recognize cards as RTX 3070. The name of the cards was GA104
- The system not even once starts with total numbers of cards. He starts with 5, 3, 7, 9 random number of cards. If, by chance, it started with all 10 video cards, it took about 5 minutes until they started to fall one by one.
- The following error apears when the rig starts “[nvidia_drm] [GPU ID X] Failed to allocate NvKmsKapiDevice drm:nv_drm_load ERROR”
- If I wrote in console nvidia-info got “Nvidia driver is disabled (use --force)”
So, after 24 hours of chaging components, settings, OC, etc I changed few risers and switched to ASRock H110 BTC PRO and system started to work just fine. I let the system at my home 2 days and worked without any problem. For 2 days I restarted it once every 3-4 hours to make sure that the error with GA104 or Nvidia drivers not found does not appear and everything went well.
Part of the problem, I think it was from the risers, one or two risers had problems and ruined the rig completely. I chose a much more popular motherboard like the ASRock H110 BTC PRO + because the TB360 is new and I thought it might have bios problems.
But as bad things don’t end easily, this morning I woke up with half a cards offline.
5 video cards appeared with X and the other 5 video cards were online, but they didn’t mine. I did not receive any errors in the system, they were simply offline. I rebooted the rig and it started to mine without any problems. The error with GA104 or Drivers not found I think is gone but now my video cards are falling for no reason.
HAVE, Somebody, ANY IDEEA, WHY?!
But the rig worked fine 10 hours and just in the morning got this error. After restart start working just fine in 10 seconds.
