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

You should be able to reach over 700 h/s with almost any card, after flashing your cards.
Before flashing you need to check what kind of memory you have on your cards (mostly hynix/elpida/samsung), then use a bios corresponding to that memory, or edit your bios by yourself with Polaris Bios editor 1.41 (basically you copy the 1500 MHz memory strap to 1625,1750 and 2000 Mhz mem straps for hynix and elpida, for samsung you copy 1750Mhz strap to 2000MHz)
For flashing the ROMs succesfully, you need to close de miner and open atiflash in admin mode.
Last thing you have to do is using WattTool to overclock memory frequency (check the differents threads about benchmarks to get an idea of the settings you need)

If you pay for electricity, i would recommend you to use -a 2 mode, which works very well on the RX series too.
"-a 2" low power consumption mode for 290/290x cards. A bit less speed (1%) but less power consumption (10-15%)."

About the lagging, it's hard to tell.
What's your CPU ? Do you use your computer for other purposes than mining?

I'm sure this has been posted but where can one download these roms? Thanks

I would advise you to mod your bios' by yourself since it's very fast (just copy the mem strap as i said in the previous message), and that it allows you to be sure the resulting BIOS is compatible with your GPU.

If you are too lazy to do so, you can check here :

But you need to flash the adequate BIOS
