with the updated version of Polaris Bios Editor using the supplied timings instead of copying the 1500 timings I get roughly 0.2 - 0.4mh more per card
There appears to be two versions of Polaris Bios Editor V1.6 ?
The one from
https://github.com/jaschaknack/PolarisBiosEditor has the "One Click Timing Patch" option and the other has the option "Apply Ubermix 3.1 Samsung Timings" - both say they they are version 1.6.
I've been using the "Ubermix" version with no problems - can't remember where I downloaded it from.
Does anynoe know what the difference between the 'One Click' and the 'Ubermix' timing are ?
I'll have a go myself and see if I can spot anything - I may be some time figuring this out.
The jaschaknack PBE v1.6 is the most updated version. The 'one click timing patch' includes the Ubermix v3.1 Samsung timing as well as performance straps for other memory types. It depends on the memory type/types detected on which performance strap is applied.
