Hello Ciprian,

I’m trying to mode the bios for my RX470 Sapphire Nitro 4Gb Samsung memory. I don’t have a switch for the bios, i have 2 switches. (you can see in the attached pictures more detalis). The problem is that with the moded bios the card is either not detected anymore by the claymore, or when it worked (after many retries) is not going higher than 14Mh/s. Right now i’m mining ETH+DCR at 26 Mh/s and 780 Mh/s per board. I’ve tried to copy the valuse freo 1700 to 1900 and 2000, but also to copy the values from 1625 to 1750 1900 2000. None of them working. I also used the bios.rom you have uploaded but is says ID Mismatched. Do you think it’s possible to mode the bios to go at least 28Mh/s ? I have only tried this for one board out 6. I’m adding some pictures with details. I’ll buy you more than a beer if we can manage to improve the current hash rate. Thank you. https://uploads.disquscdn.com/images/3f2a8c4f66c48941971280566e9375b4ad9cd4f57999caf25050d70fbc03914c.jpg https://uploads.disquscdn.com/images/8809250a5b5fd9259a2348772364fd136137c0b9d89899633ef8ae9894158f35.jpg

Hello Ciprian,
i am wondering how easy and how fast this can be undone, and what would be the needed steps.
Esspecially regarding the BIOS switch, which is (hopefully) left in the left position towards hdmi cable during the flashing with a modded BIOS right ?!

Regards

Hi,

I have bought 6 RX 470 with serial A1725. I have searched all internet but I couldn`t find any solution how to overclock these cards.

As you see in the screenshots, GPU-Z shows the memory as Hynix BUT Polaris shows two vendors (Hynix and Elpida ) in VRAm section.

I`ve connect only one card for now, It gives 19.8 Mh/s :(( .

Is it possible to improve the speed to 25 mh/s at least ?

Thanks for your help.
