I can't turn the fermat test off because then it crashes straight on start and I get fraction assserts error.
I have gotten the program to work for roughly 30-45 sec then it crashes.
I have 2x7990 and I am running all 4 cores.
I have the latest drivers and I run on windows 7 64 bits.
I have the following settings

host 127.0.0.1
port 9332
user username
pass password

protocol primecoin

worksize 256
aggression 16
sievepercentage 10
sievesize 1000000

primecoin_address AbJSsYd5cnj2MxmBEHxtWo8kwpt7qA77xM
debug false
opencldebug false
cpu_mining_threads 4
use_gpu true
use_gpu_fermat_test true
getwork_rate 1000

Any suggestions on how to fix it?
