I flashed my 5570 using RBE and changed the core voltage from 1.05v to 1.1v then from 1.1v to1.05v again. But guess what! When i did that I couln't overclock the memory safely over 720 Mhz:shadedshu; where previously I could easily overclock my RAM to 870 Mhz over! Can somebody upload a healthy BIOS file for me, PLZ!!! It would show a crazy amount of artifacts if I overclock the memory. Now my games won't play at an acceptable FPS( yes that small difference makes some games playable. I think i damaged my card. I thought it was impossible to set different voltage's without the V-mod. If u guys want any more info just reply and ask. I can upload the Bios from my grafix card if u want!
