Modding 570/580 bios

[bgaddis88]

I've gotten 4 sets of 570/580 cards now

Auros 580 4g

Gigabyte 580 4g

Sapphire 580 4g

Strix 570 4g

I've unsuccessfully attempted to copy the 1500 memory on everything but the auros 580.

All of the other bios files show the memory timing of like 4392028302 instead of 1500.  I assumed it was just polaris bios editor reading the information wrong, but I've tried copying where the 1500 data should be and the cards won't mine.

Any suggestions to getting modded bios for these cards?  Any help would be greatly appreciated.  I'd love to pay someone to get me a working mod bios for some of these cards.

Try copying 1750 timings to 2000. Safer bet, especially if samsung memory.

I have Gigabyte RX580 Gaming 4G, and successfully copied 1500 strap with Polaris bios editor, and it works fine

Why does everyone say that you can go with lower straps on other chips, but Samsung needs to be 1750+?

Samsung straps are more tightly tuned from the start. Generaleramon already put in WEEKS of work tuning the individual timings on Samsung memory, so don't bother just upcopying straps and see his "Uber Mix 3.1" under "RX480/580 Performance Timings" and send him a thank you:

I can't decode what he means, is his UberExtreme for 2000 timing only? Or do I paste it to 1750 and 2000? Tnx
