Hi, Im having problems with SMOS after I added 5th R280x card to my rig. I cannot get it stable even with 4 cards anymore.
My setup:
Msi 170a gaming pro carbon
Celeron
4gb ram
Ssd
Asus 280x cards
Asus 290 card
MSI 280x cards
Asus 280 card
Asus 280top card
2 basic PSUs linked together to feed mobo and usb risers
2400w server power with breakout board to feed pcie power
Usb risers from china
Right now just 4 280x cards are connected because of these stability issues but still not working.
Clocks are 950/1500 with 0 power adjust.
I have tried several different clocks but anything else than these make this rig even more unstable.
Before I tried to add fifth card this rig worked great. Now I have over 460 restarts in this rig and I dont know why this started.
In many reboots I get these errors:
Set clock failed for adapter x
ADL_Adapter_Active_Get failed
Cards not detected
Any advice?
A few generic troubleshooting steps I'd try..
1. Remove all but one GPU
2. Fresh install of SMOS
3. Add one GPU at a time, overclocking each one individually
This might narrow it down to a bad GPU, or riser, or PCIE slot.
