Ok here what I had gotten:

~/JohnTheRipper/run$ ./john --session=opencl 
--format=PBKDF2-HMAC-SHA512-opencl hash.txt
Device 0: GeForce GTX 750
Using default input encoding: UTF-8
Loaded 1 password hash (PBKDF2-HMAC-SHA512-opencl, GRUB2 / OS X 10.8+ 
[PBKDF2-SHA512 OpenCL])
Cost 1 (iteration count) is 48543 for all loaded hashes

So if the "48543" is what you thought would need to be over 500K to 
account for the speed, then I suppose maybe there is indeed a 
problem...? Currently been running 1 day, 13h, on phase 3/3 and 777p/s
