hello ther i have msi rx 470 4gb with faulty memory banks (k4g4 1325fe - hc28)

i am planning to replace it with skhynix or elpida brand memory banks for the reason thats the only spare i have.it from rx 470 also
i heard it needs to modify some resistors..
is there anyone can tell me what should i do ? any advise ?
a reply will be much appreciated .. thankyou guys

Radeon should be searched for a suitable bios for a suitable memory
