Radeon RX 580 Samsung K4G80325FC OC settings

First time poster.

I have recently acquired 2 Samsung 580 GPU’s. However I can’t for the life of me find a way to make them work. I mine already with hynix 580s, but these samsung cards refuse to use the same OC as they do. every time i attempt to put any OC settings on they crash immediately. I would appreciate any advice if anyone is using these cards themselves.

Download their bioses, mod them with ubermix 3.2 version not the 3.1
Use something like the following:

1180 core clock
850-875 core voltage
800 Memory controller voltage
2100 Memory clock
Aggressive undervolting ON
amdmemtweak --REF 20.

And post the OC settings of the rig you have
