I'm sorry but I don't understand: When I save BIOS from card (R3870 DDR3) to file with GPU-Z, and load that BIOS in RBE, in Method 1 I have "HD 3870 - 851/1143/1100/1587 MHz". If that sig is already in BIOS, why in my CCC OC limit is "880/1100" (def. freq. of my card are 780/950)? Is that *.rbe for DDR4 cards and can't be used on my DDR3 version but how that sig is in BIOS of my R3870 already? I didn't flash anything for now, I'm confused... BTW, can I somehow flash from Win?
