Sapphire nitro 570 8gb questions

[Gmzombie]

So does anyone have a good bios for these sapphire nitro 570 8gbs. Hynix ram I can't get past 27.5. I have tried a few custom straps but I can't get past 27.5 anybody else have these?

Use the Polaris Bios Editor v1.62 'one click timing patch'. It works great with all my Sapphire Cards. That with -96 mV undervolt, power limit -15%, 1150 MHz core, 2000 MHz memory should get you to ~29.5 MH/s and 750 MH/s DCR dual mining.

If you only copy straps from lower to higher, you won't get far... The Hynix timing in PBE should be better, but it can be even better.

I have 580 Nitros 8GB Hynix in my rig and I used a timing strap from a 480 4GB hynix card which was much more aggressive. It also worked very well in my 580 Giga Gaming 8GB hynix cards too.

I've pasted it above if you want to try it or see if maybe you already have it on (as it is floating around the net everywhere as the best hynix strap to use (if you want to google it if you don't trust me))
Only use if 400/500 series cards with Hynix type memory and only ever change the top two fields (2:2000-2:2250 or your card's equiv) to avoid any possibility of bricking your card.

Also, make sure you are using the AMD blockchain drivers. They make a huge difference for the 400/500 series cards.

This strap is not from any hynix memory. I know from wich memory they are. But you can open any 480 4Gb bios with hynix memory and you will see these straps:
