I understand that Claymore miner is done now, but using 1080 Ti cards with every other miner I get ~18MH/s instead of ~47MH/s if the DAG is over 4GB in benchmark modes (win 8.1). What am I missing? Linux works well so I'm guessing it's some driver or windows limitation? Is there a workaround?
Had the same problem on windows and couldn't find the issue.
Switched to HiveOS in despair.
The first time I had this problem was because of lack of memory on the motherboard so I added 4Go on each rig.
But since dag 384 I also had the same issue and couldn't find a solution.
Changed the drivers, reinstalled the OS, tested various miners, checked Bios config, no luck.
You can test with windows 10 but if it fails go to linux
