You have output video on your cards or your internal gpu?
This is my test bench machine with 1 GPU only. The output is directly from my GPU HDMI.
So besides that AfterBurner issue, what is your experience concerning the EPOCH hashrate drop? Did they fixed that on the current driver?
I managed to overclock my card to 2000, but I haven't restarted the miner since, so I may have a lock screen on DAG generation. I cannot confirm yet since I am away and playing with teamviewer, so if the PC freezes I won't be able to restart it. Still waiting for my smartplug from Amazon. This is not bad but I do not think this is a DAG resolving release. I was at 27.3 before, I am at 27.5 now but with 50Mhz more in memory clock, that could be the only factor raising my Hashrate. I would not recommend this release yet, since without Afterburner, I cannot check the same settings and be definite about any opinion.
Claymore and Wolf0 should be the ones to really answer this question, since they have the real means to test bench this release.
