Flashing BIOS of Sapphire Rx 470 NITRO (not +) 4gb - Elpida

Dear community! I have great news for you!! Finally (after hours, days, almost weeks... of suffering looking for a way to flash the Bios of this model of GPU) I got the link that will work for flashing the Bios, and the rest is just a matter of following the traditional procedures to flash a memory through ATIWinFlash. I have pair of the GPUs describe in the title of this post. I have been mining Ether with them, with no OCing they can do 22Mh/s. After OCing with Afterburner (Core Clock 1050, Mem. Clock 1920) each GPU was making 24Mh/s. After the flash, they started making 25Mh/s without OCing, and 27Mh/s OCing with the same numbers I used previously. I tried tweaking the Afterburner in order to get better results but it turned very unstable. I'm trying to find out the reason why I can't assign a higher speed to the Mem. Clock without getting a blue screen. I would like to know if the system's RAM or CPU might have something to do with this issue, but that will be my next research (unless any kind soul can explain me the reason of this hehe...)

This is the link to find not only the Bios for the Sapphire Rx 470 Nitro (not +) 4gb (elpida), but for many other GPU models aswell: https://anorak.tech/t/anoraks-vbios-collection-optimized-settings-for-performance-power-saving/13/3

You just have to sign in (if you don't have an account) for free, and then you're free to download the one you need. I used the one that says "hynix elpida memshift." but there are other options for low energy cons, and OCed. I followed the procedures in this video: and all worked just fine. I have the Crimson 16.9.1, Polaris 1.4, and ATIWinFlash 2.7.4.

Good luck and Good Flash!
