Hello all,
Yesterday I have posted this question in other thread, but unfortunately I got no advice, so I am trying here today. I am getting very frustrated with my 2 Saphire VEGA64 cards and castXMR setup . The problem is that one of my cards just stops hashing after 1-6 hours (randomly) and miner freezes. I am getting no errors reports in CastXMR or wattman at all. The miner seems to be active and is reporting hashrate for one card. When I am trying to use command "q" to quit it does not react. I have to close it's window and them my wattman setting resets. I am using blockchain driver and applied 1050 registry mod. I also lowered power limit to -21% and GPU. Temperature is below 50 celsius. Please give me some ideas/hints what can cause this problem. I spent several days reinstalling my system and it seems that nothing works

I am completely lost

Yesterday I sent one of my Vegas back to the store. Now I have 1x Vega64, 1x rx580 and 1x rx480. RX580 and RX480 are mining ETH and working without problems. Vega64 is mining ETN on castXMR miner. I changed PCI positions, reinstalled everything and now also disabled IGPU (intel) and the error is still there

Vega just randomly resets to default values (and everheat to 75C) while not submitting any information to CastXMR

Can anybody help me? Please shot any ideas ... I am really desperate

Have you tried mining without the registry mod, or it could be just the MOBO giving you a headache.
