I tested a few modifications with my MSI Rx 470 8Gb mircon Memory with a pretty nice end result:
1750 Straps 100 TDP 1850mem = 25,75
1750 Straps 100 TDP 1900mem = crash
1875 Straps 100 TDP 1850mem = 26,0
1875 Straps 100 TDP 1900mem = 26,7
1875 Straps 100 TDP 1950mem = crash
original bios with wattool 1900mem = 23,4
original bios with wattool 2000mem = 23,5
1500 Straps and 1750 Straps = crash
1500 Straps and 1750 Straps + inc. powerlimit coreclock 1330 and mem 1850 = 26
1500 Straps and 1750 Straps +Wattool 1900 mem = 26,5 @ 71W (GPU-Z)
1500 Straps and 1750 Straps without Watttool 1950 mem = 27,5 @ 96W (GPU-Z)
1500 Straps and 1750 Straps +Wattool 1950 mem = 27,24 @ 74W (GPU-Z)
1500 Straps and 1750 Straps +Wattool 1950 mem and 1150 Coreclock = 27,5mh/s eth and 700mh/s DCR @ 95W (GPU-Z)
Ok i tested my Bios on 2 out of my 3 micron 470s, it works just fine. Flash it and try to get the Memory speed as high as it goes ---> finished
if u want u can lower the Coreclock with the power stages but there is no need for this, it only lowers the power consumption.
1. 470 max mem 1950 core clock is 1150= 27,5mh/s eth and 700mh/s DCR @ 95W (GPU-Z)
2 470 max mem 2050 core clock 1246 (default) = 29,2mh/s eth and 740mh/s DCR @ 107W (GPU-Z)
All in all i hate mircon memory
