I got my 270X uo to 450 h/s and I'll take that but I can't get my 280X past 445 for nothing.

It has the Elpida memory. I tried auto set, -a without the -h, -a with -h. Changed the -h from 832 (which it showed at beginning) 864 and 800. Nothing.

Runnung the 13.12 driver version on Windows 7. I can't down clock my core under 1,000 and have the memory at 1,575.
