Hi, my friend has two rigs with 6 GPUs RX 580 sapphire nitro 8GB.
All two rigs ware working perfectly for months, but last month one rig works 10% weaker and few days ago it is 50% weaker!
Settings are all the same on both rigs.
Take a look screen shots:

the effected rig has been updated with the recent w10 update. Revert back to the previous driver should get the rig back to normal again.
