I actually never questioned this but...
I flashed Mattthev's timings on my RX 570's back in the days I was mining ETH. I've kept those timings on ever since, even though I've been mining Cryptonight coins for the last months.
Are these tight timings actually beneficial for that algo? Or would I be better off flashing back stock bios and increase clocks?
Sure you can use them, there are some differences but you will get way higher hashrate even with timings optimized for ETH to mine XMR with than stock.
I was about to flash the modded bios for my RX470 (knowing that I have Samsung memory I presumed that the manufacturer was Gigabyte) but after running SRB Polaris, I found out that my card is a Sapphire but with Samsung memory!
@Mattthev being very helpful, will upload in the coming days a modded BIOS for this version of RX470 Sapphire with Samsung memory in
https://mining-bios.eu Kinda busy, I will try to add it as soon as possible.
