Sapphire Radeon RX 570 16GB Issues

[BallowandSunder]

I've tried to use PBE 1.7 and even the purchased PBE 3 Pro for the Sapphire Radeon RX 570 16GB Blockchain card and I run into quite a handful of issues with both products, from black screen to blue screen, multiple thread stuck issues from system to device, mining crashes from ??Mhs to 0Mhs after 5 to 10 minutes of mining. (And this is after following all the instructions in the guide word for word on the bitcointalk page)

It seems PBE products doesn't 100% support and give proper 1 click timings for the RX 570 16GB model, but it does acknowledge the data of the card.

When set back to stock Bios everything works perfectly fine again with ETH for example; left side original bios switch 28mhs @ 152w from the wall, and right side original bios switch 24mhs @135w from the wall.

These power draws from the wall are ridiculous, and was hoping PBE was the cure as I have seen other getting the sweet spot between low power 75-90w and 29-31mhs on RX570 8GB cards with PBE. I would appreciate any help in finding the sweet spot with this Sapphire Radeon RX 570 16GB Blockchain card using PBE to lower the power while hitting decent hashes.

You're an idiot? PX 570 16 GB does not exist in nature! Judging by the screenshots, you have Radeon VII (Vega 20). And I have not yet met programs to change their bios.

@yoshcat RX 570 16GB models do exist, made by Sapphire... Perhaps you missed the boat, but these cards were designed when Grin was launching. Also Radeon VII's are "Vega" architecture not "Polaris" architecture. Please do more research before calling someone an idiot. If you google Sapphire Radeon RX 570 16GB or RX 570 16GB Grin they pop right up in the search.
