I'm a newbie. Not done any BIOS modding myself yet, but I think that by modifying the BIOS you can change memory timings. You can't do that through MSI Afterburner for example.

An advantage of BIOS modding is also that the modification is on the card itself. You don't have to re-apply them on each boot or if you use your card on another rig.

There's disadvantages as well. BIOS modding must be done very carefully as you may brick your card. And you probably can forget about warranty if you tamper with the BIOS.

Anyway, it all comes down to how much performance you want to get out of your cards and how much hassle you want to go through.

I'm definitely going to try BIOS modding my cards (Sapphire RX580's), but first I'll see how far I can get with Afterburner or similar.

That some thing I worry about brick my card. lol

This question is in my mind for a while.

Now I have 2 RigS of AMD+Nvidia, I use MSIAfterBurner and Radeon Settings for tuning my card.

99% of my cards got very close hashrate as the card that already mod bios (Not sure about power consumption rate).

I know that if you have many many rigs flash gpu bios is very useful, but in my case I only have 2 rigs and I am fine to resetting again when system error or new card installed.

So does flash GPU bios has another benefit that I miss? Should I learn do that?

Like you said it comes down to power consumption rate. If you have no electricity costs and heat etc isnt important than it doesnt make a huge difference.

But if your mining at home and you want the fans to be low speed and GPU temperature low better to mod the bios and undervolt

That properly true. May be it's time to learn new thing. Thanks
