Collatz: Use at your own risk

[Egilman]

Thanks, I'll have to dig up that thread where I got my settings from. I'm only outputting about half per day what I was, so I need to redo all that on each rig. Oh well...

verbose=1
kernels_per_reduction=48
sleep=1
threads=8
lut_size=17
reduce_CPU=0
sieve_size=30
cache_sieve=1

Anything from a 7970 on up should handle those settings with ease. I know mine do.
