Hello, I got a big Problem with my Rig. When I run 5 GPUs, everything is fine - more or less.
But when I add the 6th GPU, the System is not stable anymore.
First Linux starts getting really slow and has problems on booting. Sometimes it gets stuck at the boot-screen and i have to power off/on to start the rig.
Then I start the Claymore miner and I can see that the 6th GPU is running on 19-20Mhs only (should be 26 at least).
After a while things start getting weired. Alle the GPUs begin to slow down on MHs and GPU numer 6 goes down to 4-5MHs. Few minutes later the system freezes and thats it - i have to manually power off.
Here is my Rig:
Intel G4400
Msi Z 270 A Pro
2*Corsair CS650M
4GB Kingston Fury Black
4* RX 470 Sapphire Nitro+
2* RX 480 Sapphire Nitro+
Xubuntu 16.04.2
Driver: amdgpu-pro-17.10-414273
Claymore dual miner 9.5
(I have already tried to use a different 6th GPU, but I get the same errors, so the GpU is fine)
