I've checked some logs, the problem on pool side, pool sends different epochs for some reason. You can ask their support why it happens.
Any update for Windows 7 users using blockchain drivers that face issue of miner crashing as soon as it detects the cards ?
I cannot install these drivers on Windows7 at all, now I have to reinstall Windows after several attempts. Try any different OpenCL miner to confirm that the issue is related to my miner, because the reason can be drivers.
Don't know if anyone cares but I was able to do the amd clean install with the win7 driver on an old win8.1 rig w/5 x 280x that normally run Claymore's ZCash to see if the dual ETH was any better. Took longer than normal to install, thought it locked up but it was not. No real change so went back to ZCash also still the same.
