Everyone warns that you can brick your card but it seems like everyone does it and I don't read that many horror stories. Is it really that easy to brick?
imo, no. if you make CUSTOM timings, then yes you can easily brick it, but normal everyday miners use premade professional BIOS's, and simple strap copying
those pose VERY little risk of bricking your card.
if you use a premade bios tho, know where it came from!
my suggest is just get "polaris bios editor" and google fu how to do it yourself
just as a noob, ONLY copy straps haha
again, custom timings are for advanced users, and MAY brick your card ;p
keep in mind bios edits void warranty when done in any way. (people have told me they just flash back stock BIOS b4 RMA and it works tho
)
