Thank you for all of the replies, guys! But I think you misunderstood me. I've said "the GPU is a Chinese replica" earlier. I don't doubt if it's a legit one, I'm sure that it's fake. My question is more like - is there any way I can run some miner (old version, etc), so I can see the hash-rate? This is the GPU-Z screenshot:
https://i.ibb.co/FgvYHw7/gpuz.pngWhat I've tried so far:
1. Installed the driver 390.77 from the Chinese CD - Windows DOES recognise the card
2. Installed the driver 390.77 from the NVidia website - Windows DOES recognise the card
3. Installed the driver 465.89 from the NVidia website - Windows DOES NOT recognise the card
Errors so far:
ETHMiner: Out of memory
LoLMiner: Problem in loading kernel
PhoenixMiner: Compute 2.1 (minimum 3.0 required)
