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.
There are different forks of PBE listed on

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.
Funny, I have the overclock.net link above already bookmarked and had a look at it before posting but couldn't find a link to the PBE v1.6 I downloaded..must try harder.
I've just had a play around with the jaschaknack PBE v1.6 and, using an RX480 bios, clicking on 'one click timing patch' pops up the window "Samsung memory found...applying UBERMIX 3.1 timings...", and tried it on an RX560 bios and it pops up "Micron memory found...applying GOOD MICRON MINING timings..."
Think I'll start using the jaschaknack PBE v1.6 version from now on as it looks like it can detect which memory the card has and apply the appropriate timings - although sometimes I found that simply copying 1750 -> 2000 worked better on some cards, the Ubermix setting were a bit unstable.
