Hi together,

First of all, thanks for your help.
it is up and running now:-))).. After a really hard weak of troubleshooting, the new minig rig i working now, with 4 X RX470 Nitro+ 4GB..
What the hell.. Arizer damaged. 2 of 4 GPUs damaged, PSU trouble.. And many many more..
Now, i´m wondering how i can optimize the Hashrate.. But step by step. First thing. My Rig is lagging really hard, when mining over GPU Miner v9.7.
Is that normal, or is this something i can fix, with better settings? Sometimes, after hours, the rig just shut down.
Is there something i can do. I tried out tons of crimson drivers. Most of them doesn´t work for Win7 64 bit and don´t identify my cards. I only got V16.11.1 and 16.11.4 to work. When i run claymore now, with the following command i get 2450 h/s. This are about 610 h/s per card. Is that good, or bad. There are so many comments, with different hasrates.

NsGpuCNMiner -o stratum+tcp://xmr.pool.minergate.com:45560 -u paapolinho@gmx.de -p x -a 3 (i tried A 4 and A 3 also, without changes)

I also tried to flash the rom, but it doesn´t work. ROM can´t be deletes, was the error. Is there a trick, when i have to push the button on the card.
How can i check, if the card is in the right mode to write the rom? When i push the button, the light is changing the coulor frequently. Is this the right mode?Do i have to reboot, after pushing the button. I´ve found someone who has modified the rom, for rx470 cards, so that i can be sure, it works.
Can somebody tell me, what i´m doing wrong?

And hopefully sombody can help me to optimize my cards.

Many Regards,
Scandalrosi
