ir_cow Posted December 14, 2019 Posted December 14, 2019 My only issues that came with a modified bios was the AMD drivers wouldn't install. My work around was to just change those tables and nothing else. Reflash the card with the edits and it worked. Only when I changed all the values did it give me that problem. My experience with the RX 470 / 570 BIOS editing is limited so I'm not much help. Share this post Link to post Share on other sites More sharing options...
mihgeo Posted December 16, 2019 Posted December 16, 2019 @ir_cow yes,now i read in many sites little modification=code 43,thank you! Share this post Link to post Share on other sites More sharing options...

ir_cow Posted January 2, 2020 Posted January 2, 2020 I don't know for sure if will be okay, but the fan RPM will surely be different. Only one way to find out. Flash it. If the fans don't work, flash it back. Share this post Link to post Share on other sites More sharing options...
mihgeo Posted January 14, 2020 Posted January 14, 2020 (edited) @ir_cow hello again and thank you!i have new question,bizare question... my pc: Cpu i5 3570,motherboard 1155 h61,8 ram ddr3,:asus strix rx 470 with 8vram,power supply: fsp hexa 85+ 650w. The video card has the default frequencies = 1250 Gpu and 1650 Vram,I have the same score in benchmark, but also in games (in the same area) and if I put underclock at 1200mhz and if I put overclock at 1435mhz ...What I noticed:If I increase the frequency, the Gpu lowers my fps.If make undervolt (default frequency), my fps will increase slightly.the temperature does not exceed 70CWhat do you think it could be?

ir_cow Posted January 15, 2020 Posted January 15, 2020 Well if you decrease the stock frequency this will lower the FPS. If you overclock too far, it will introduce errors and lower the FPS (or crash). Most 470, 480 top out around 1350mhz. 570, 580 1400mhz and 590 1650mhz. When you undervolt, my best guess is the temperature goes down, which gives a overall higher boost clock speed. Share this post Link to post Share on other sites More sharing options...

I'll come over tomorrow to help him install the headache rack and on his truck. We'll try to flash it and see if it will make a difference.

I want to ask for my nephew because he is planning to do the same thing as you Share this post Link to post Share on other sites More sharing options...
