GPU is working, stats show hashrate, but no shares is found (tested about 30 minits),
with same difficulty (0.2) even celeron J1900 (which hashrate is less about 10 times)
can found 10-20 shares.
About Xdag - that miner version i use at that moment not work.
And what miner version you are using for Xdag? Really hard to help you with zero information.
My first test on xdag = it is working = i will test it deeper but i am sure all is fine.
Second i tested yescryptR16 on a GPU = success shares found and all working flawless.
Tested with 1.1.3
aunt edit says:
XDAG mining work flawless - the failure by BoozyTalking is a wrong wallet - a wrong wallet results in the reconnecting failure after every sent job to the pool.
If i have more time later, i will look into the Firo failure - but i think it is also an failure by BoozyTalking
