Indeed, IF we can get the frequency
290/X and 295X2 only have 10 straps.
400MHz, 800MHz, 900MHz, 1000MHz, 1125MHz, 1250MHz, 1375MHz,1500MHz, 1625MHz, 1750MHz
Each time you go past a frequency/strap end marker next strap timings are applied ie 401MHz uses 800MHz timings
The 390X rom have 12 straps, rather than go in sequence they go like this.
400MHz, 800MHz, 900MHz, 1000MHz,1125MHz, 1250MHz, 1375MHz, 1731MHz,
1500MHz, 1625MHz, 1750MHz, 2000MHz
Now after viewing this god knows if on a stock rom when RAM clock goes 1376MHz+ does it start using the 1731MHz timings or skips that and goes straight to 1500MHz and so. This could be tested.
Lard already knew 390X had extra straps, he fixed the setup, one of his posts highlights this.
He's made the 390X roms used in this thread's post 1 as:-
400MHz, 800MHz, 900MHz, 1000MHz, 1125MHz, 1250MHz, 1375MHz, 1500MHz, 1625MHz,1750MHz, 1900MHz, 2000MHz

Perhaps their hitting 1700MHz as their using 1731MHz strap all the way from 1376MHz to 1731MHz plus with what the Stilt has highlighted.Edited by gupsterg - 10/21/15 at 2:26pm
