Plz Help with MSI Armor 470 8g Hynix mod

[MegoBasha]

Hi guys
I have MSI Armor 470 8g (non OC I guess) Hynix with ~19mh stoke
I tried to mod it but all i can get is 22.5mh max with 1150/1750 stable or 1206/1750 not for so long then it becomes 1206/1650 by itself.
all the other straps either crash or give me less Hash.
I tried to mod the bios by coping 1500 to above values.
then i tried PolarisBiosEditor-master1.6.2 (one click timing patch) with no good.
the card has a timing values (400-800-900-1000-1125-1250 -1375-1500-1625-1750-2000-2250) which i couldn't find in any tutorial about it.
the bios version number is a little bit different then other rx470 in the youtube videos.
plz help

Some people just found a batch of MSI Armor Rx 470 8gb cards, which have been out of production for a while so surprised me, but these cards are a pain to mod, almost no straps/clocks work well and the default memory timings on these cards are horribly bad, so copy pasting them to lower bands does not work.
Luckily for you, I have modded these cards for people before, and was able to get these cards to 27.5mh/s.
Here's the strap that I use :
777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB0300000 01B162C31C0313F17
Open your BIOS in PBE, and copy paste this strap to 1750 and above. Then using something like OverDriveNTool (Or MSI AB beta 16+), and then set core to 1075, mem to 1875, both at 900mv. Then push it slowly, I was able to get 1075/900 core and 1925/930mem stable on all cards that came to me. Best of luck.

just posting to let others know that it worked.
and the strap you mentioned has a space between the numbers
777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB0300000 01B162C31C0313F17
after burn settings:
1165/2065 - 925mv
many thanks man for your time and effort.
