I know there are already posts about this problem , but did not found workaround , on mainboard with 12 polaris gpus win 10 1709, and claymore dual miner ( tested with 11.2 down to 10.6 ) ethman do not work when all 12 gpus are mining , lost connection immediately , when start just 8 gpus to mine ethman works without problem , it's not cpu problem , cpu load stays 20-30% , remote software is working good ( teamviewer , splashtop , tightvnc ) , i tryed phoenix miner 2.7c recently which works with ethman and with it there is no problem when 12gpus are mining , cpu stays the same load 20-30% , so the problem must be with claymore's miner socket implementation , web server or something like that when gpus are more than 8 , or some hardcoded setting remain from the times when driver and windows accept only 8 gpus . Can you check and fix this problem please .

p.s: I read through the posts and did not find workaround for this , so if there is one , my apologies.
