Thank you Eliovp for the info.  I only tried raising the REF from 5 to 9 and got a 1.178 increase from my MSI Rx580 G8 Hynix and a 0.739 increase from my XFX RX580 G8 Samsung memory.   I'll play with the RFC after I now the 2 card types are stable.   Update:  I raised my REF to 10 for the last 12 hours and has been stable.  Original 27.803 to 29.313, a 5.43% increase and Original 24.852 to 25.854, 4.03% increase.  Thanks again Eliovp for the info!   RFC is next for both cards after another 12 hours.

You're welcome.

Who know how REF named in decoded Polaris timings?

It's not there, Refresh Rate is a completely different register and is not a part of the vbios Strap.

I'll be releasing a new CLI version soon with almost all timings exposed.
Some things that no one has seen before (or almost no one)

GUI version i will update when i find a bit more time (with some juicy stuff :p)

Cheers!
Hope there'll be some juicy way to tweak GDDR6 timings on RTX cards... Smiley
