Actually my card is working fine (except im on my old pc with 4 core athlon and i needed to install 2nd windows on my 2nd hdd) because i roll back to my old bios but i just want your attention to help me to choose proper .rom to let me OC my card past 1050mhz.

So like i write in title i bricked my 7850 asus 2gb gpu. I recently had issues with 14.6 drivers but i fixed that. However watchdogs isn't working like it should (or maybe game is very bad optimized) and i was mad because i couldn't oc my card (it always crashes after 1050mhz [i tried asus gpu tweak/msi afterburner/trixx/few others none worked and looks like changing voltage doesn't work [i can change them but gpu-z shows it is still the same]).

So i decided to change bios and i set up dos flash pendrive with 2 .roms

I used one of those techpowerup.com/vgabios/index.php?architecture=ATI&manufacturer=Asus&model =HD+7850&interface=PCI-E&memType=&memSize=2048

015.017.000.000.000861 << that bios i installed
015.017.000.001.000000 << original bios oc blocked

I'm not sure which one i take (because there are like 6 same bioses - are they the same or i should try to use them?). So i start up my pc again and get into dos using my pendrive and wrote dir and then backup my original bios and then atiflash~1 (idk why it wasn't just atiflash) -p -f 0 asus7850.rom after last line generated by dos i restarted my pc and my screen was black.
I went to sleep and later next day i build my old pc with my gpu and tried to recover old bios, which i done pretty easy, atiflas~1 -p -f 0 backup.rom and i could see everything again.

And I'm idk which bios i need to use to unlock OC past 1050mhz my gpu :<

may be decent but my fps aren't good enough while playing watchdogs and from what i seen many ppl can reach 1200mhz easily i just found http://www.techpowerup.com/forums/threads/vbe7-vbios-editor-for-radeon-hd-7000-series-cards.189089/

do you think it would be better for me? what's maximum safe vddc (i know it is 1.3 but i want to have 24/7 safe volt)? 1.25? and how to write it 1250? or 1255? because my original volt is 1210 (1.21V)
