BSOD are
often signs of a instable system , and volts need to be added ( vcore/ NB/ FSBv/ vDIMM. are u 100% sure your RAM is oke( do a few loops of memtest86+)? If you system is o/ced i would put everything on stock first so u can outrule your system causing the BSOD and not your GFX.
For quick system check, download OCCT ( google) and do the 30min test.
