I don't get the point of people mentioning again and again about using 17.11.1 with FCU and how that has problems!
All drivers 17.11.1 - 17.10.2 - 17.10.3 HAVE SERIOUS PROBLEMS.
Sometimes Compute mode is not turning on, sometimes it turns on but crashes and Afterburner support is broken.
GET OVER IT and install Beta Blockchain Driver 23 August and enjoy using AB, Claymore etc in FCU no problem!
Do you care for release notes with official support but in practise BROKEN drivers??
or
You prefer to use the BETA "unofficially" and have a working miner??
Blockchain driver did not work with windows 10 FCU for me. I would loose 5 Mh/s per card for RX580 rig with FCT and blockchain driver combination and the system is not stable either. I have one rig upgraded to FCU and I had to use 17.11.1 to keep the same hash rate. I don't really like the upgrade because I cannot use AB and the fan setting is not working properly. we are talking about days and weeks long run without restarting the rig not reinstall windows or driver every one or two days because you would lose 20-30% of your income if keep doing that.
