Hello, any help on that?
I've got exactly the same problem: tons of "share above target" and almost no valid shares.
Anyone can explain what is this, and how to solve the problem?

Hello,
mining scrypt (is scrypt for another forum?)
xubuntu 12.10
cgminer 3.7.2
2x r9 290 sapphire
./cgminer --scrypt --intensity 20 -w 512 --thread-concurrency 32765 --gpu-engine 1000 --gpu-memclock 1250 --gpu-threads 1 --lookup-gap 2 --gpu-powertune 20 --gpu-fan 85,75 -D -T --verbose
with -T -D --verbose I get this while mining.
done some search but only bitcoin related forum threads. Can you enlighten me what's this about?
