'...I lowered RFC to 82 (crashes at 80), and messed around with raising REF. Running at RFC 82 REF 50 gives around 545H/S.. which is a nice increase.
                                          Cards also seemed stable at REF 100, and this got around 549H/S. How high can REF go? Well turns out no higher than 150 with my cards at least...'

As I said, I have not seen yet amdmemtweak example commands for RX550s or even RX470,480s, 580s. A lot for Vegas though and I understand it's where there are significant advantages.

Can anyone share amdmemtweak examples for RX550s and 480s?
Thanks
