Also I tried (but no good):
fglrx64_p_i_c-15.302-1.x86_64_rhel6_64a.rpm


Unstable files
(i checked all of them with SL-7.2,and with Centos-7.2;7.3):
fglrx-x11-drv-15.12-1.el7.elrepo.x86_64.rpm
fglrx-x11-drv-32bit-15.12-1.el7.elrepo.x86_64.rpm
fglrx-x11-drv-devel-15.12-1.el7.elrepo.x86_64.rpm
kmod-fglrx-15.12-1.el7.elrepo.x86_64.rpm

(fglrx*15.12-3* or fglrx*15.12.4* didn't work too.)

fglrx64_p_i_c-15.302-1.x86_64_rhel7_64a.rpm
