hi, i use claymore for mining witn rig composed of 07 gpu RX580 sappire nitro+ special edition.
i flashed the bios of the gpu.
my problem is that i am using just 5 gpu, because when i plug the other 2 gpu my claymore freeze https://imgur.com/U54BS80
i think that the 5 gpu who is working were well flashed with the right flash(samsung memory), but 2 other where hynis memory.
can i help me to solve my problem ?

What is you OS and AMD driver version ?

You can try to launch 2 instances of miner - on for the first 5 gpu's, and another for the gpu's with hynis memory.

Try this.

i am using win10 redstone 2, with block chaine driver 17.30.1029
but how i can use 2 claymore ???

Check the Readme file for claymore
There is command line option like this

-di    GPU indexes, default is all available GPUs. For example, if you have four GPUs "-di 02" will enable only first and third GPUs (#0 and #2).
   You can also turn on/off cards in runtime with "0"..."9" keys and check current statistics with "s" key.

Run first claymore with -di 01234, and second with -di 56, for example

thank you, but do you have any idea why the claymore freeze

I think this is some kind of problem with the drivers, because in the screenshot I see that the miner only sees 4 cards.
How many GPU you see in Device Manger ?

Try reinstall driver or use 16.12 version of Crimson.

the moment when i took this picture is was 6 gpu and the device manager recognise the 6 gpu.

i resolved the problem by flashing the gpu by the original bios.
the riser(ver. 006) was bad too and i had to change it
