I'm not sure what you mean by enter a small power.
I've got a 5GH/s ASIC device.
the pool is setting my difficulty to basically 0.007
I've tried forcing it to /0+6 but it won't go above pool settings.
I've also tried setting expiry,queue and scan setting with no difference.
I've got an additional 40GH I'd like to put on it but it just creates more Rejects/DOA and stales than anything.
EDIT:
Ok, it looks like after a couple of hours of submitting replacement shares .. it's back to normal.
Thanks.
