For the past i week i have been trying to solve this issue. I have msi490 motherboard ,two psu 1600 watts and 850 watts, 4 msi 3090 gpus. Three of the gpus work perfectly fine for days and temps are good and hashrates are good as well. The moment i add the fourth one the system runs for an hour then retstarts.
1: First i thought its power then i bough a separate PSU which is 850 watts to support the 4th GPU.
2: Then i changed the riser and no help.
3: Then tried to run any 3 GPU's and they run fine.
4: Try to change the PSU as well no help.
5: Lowered the overclocking and increased virtual memory no help.
6: Reinstalled drivers couple of times no help.
7: Checked the Windows event log and saw this error (The description for Event ID 14 from source nvlddmkm cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted.)
I am new to bitcoin mining .. so well really appreciate if someone can help me get over this hump.
