@hitmand @ipp2
i switched 18.6.1 drivers on a 470 4/8g mixed rig to the blockchain drivers to see if that's causing some issues with the 'invalid job' and @hitmand's 3 minute / gpu precompile time, but no - all should be fine with BC drivers, so at least now i know its not the driver that is making the problem.
Can you guys tell me which SRB version are you using? I see @hitmand uses 1.8.8 , have you tried 1.8.9 ?
Are you mining monero or some other CN/R coin ?
So one interesting thing about this is that it only occurs VERY occasionally. Once a day at most.
I've got all kinda of polaris cards on my rigs and after your post Dok, I went ahead and tried the 18.6.1 drivers on a single rig. I got them to mine at full speed by having the 'Radeon settings' be installed and manually one by one setting compute mode (so painful).
I can report back that it is the drivers. Blockchain drivers hang (doing so right now even) while 18.6.1 continues to work. Sorry for it taking so long to time to respond but the blockchain drivers did not fail for 4 days nearly! They just failed about 20 minutes prior to reporting this and still are while typing this.
In fact I had time to start a new test rig with 1 card with 18.6.1 and it's working fine also.
5 rigs (with 6/7 cards each)
What's interesting is when the BC drivers stall...it isn't a one time thing. They will stall through multiple blocks for up to an hour. Even if you reboot and start the script up again it will just not work and stall out. The popular pools don't matter, they all do the same issue. This points to not being a hardware issue at all.
So I think it has something to do with blocks themselves.
