For that Sapphire Samsung, try different settings from these straps. i have 2 gpu´s with that same bios and they both run 1045-825-1130 – 56.14mh @115W / 56.15mh @116W

There is many values that i would change on your Sapphire, starting from RC36 to 37, that will give u room to tighten other values, you can compare yout starps and try one by one what is working for you, like changing RFC,REF,RP values could be worth trying.
That Hynix bios xxx PIL-100. About clock´s, i would try to stay with mem 960 core 1050

RC is too tight imho, go with 36-37,REF 65535,go up with your RFC, like with Sapphire…trial and error. U should expect for sure +50mh from that Asus.
Start tuning your gpus with generously VDD, like 830…850 and dont pay too much attention to wattage at the beginning, when u get gpu stable with hash that u are happy, start going down with vdd with oo5 at the time and let them run long time with new core mV, if card start´s to act up with new core voltage, adjust core/mem/straps…or back up with your VDD.
Tuning these cards takes long time. its pain to get all values right, u need to change one value at the time run miner for some or long time to verify your straps/oc´s…some cards fails or starts to spit invalids after 20min´s others after several hours and some start´s after 1 day and the combination of values needs to be right…compared to your clock´s and vdd…and things will change when ambient temps go up/down, if u can keep gpu´s mem under 70c deg with good air flow around gpus you can expect good results, usually HBM2 will start to give issues above 70…75c deg, tho it will still run just fine with lower oc´s etc.
Good luck and “happy” mining
