Hi there miners!
I recently started to mine Ethereum a month ago, but I have a problem and I think maybe you can help me with an advice.
My rig has 4 Sapphire rx 570 pulse 4 GB with Elpida mem.
I modified the BIOS in SRBPolaris with custom timing found on this forum.
I raised the mem freq to 2070 to 2120 (depending how much the card was able to handle).
I set the core to 1150 and the voltages to 850.
I am using Claymore 11.2 with only this in the start.bat:
EthDcrMiner64.exe -epool pool adress -ewal wallet.adress -epsw x -dcri 6
Immediately when i start the miner it gives me some errors in hwmonitor (mostly under 10 errors), but after this it gives me none.
My rig runs at 124.9mh and i never had a single rejected share!
But my problem is this: from time to tine (from 1 to 7 days), the rig either restarts or freezes (simply the desktop remains like it is and i cant do nothing, even moving the mouse).
Did I undervolt it too much? Did I raised the mem freq to much? It is possible to be the PSU for the system (a no-name 450W cheap one, but worked good before)? What can i do? I would be grateful for any advice!
Thanks!
