RX5600XT SETUP
I have a Sapphire Pulse RX590 (Samsung K4G80325FB memory) and i’ve tried a lot of mods with Polaris editor, but it only works with the original bios and can’t get more than 29.32mhs without having it reported dead or rejected shares.
Could you help me to understand what I’m doing wrong?

Hi @Weiler,
Yeap! I think maybe it is the vbios modification. Try this:

Where are you from?
It’s me or yours temps are high ?
Try to Turn On Aggressive undervolting settings or raise the level of the fans …
@amackata you are my hero!!!
Thanks a lot! With your help, the lazy Sapphire is a new winner! As you can see, now it produces 31.46MHs and with low consumption (68w).
And because your advice about the other cards (6600xt), i made a few adjustments and these are the new memory temperatures.
By the way, i live in the mid-west of Brazil, a region with high temperatures.
That’s it. Hope this mod will help others! Thanks again!
Thanks for you comments @Weiler .
Now, very Nice temps for hot day Lol (I think is best to use more fans and save the GPU in this days) The coolers are more cheaper…
For me the summer is comming 
mas eu tenho pra três meses mais. Embora eu imagino que não se compara ao seu verão. (Perdón por mi portunhol/portuñol ja)
