They seem to have eaten my post, so I'll try again...
I'm getting a bunch of "false positives" running a version of CPUMiner that does X11 (I've used it on DarkCoin before).
Any clues what that means?
My miner doesn't work neither for X11. It send few share then it stay idle. I do not put any setting in the password. Also for Scrypt I've never had problem with NiceHash before (as long as I don'T not add price settings in the password).
It's not going idle, but with the debug flag going, it's giving me:
[2014-05-12 16:34:45] DEBUG: hash > target (false positive)
Hash: 000000cb67446e5ce7e7b05fa59385a2f3f5fbbcbbc70dab5c5be84a5f6316b3
Target: 00000031ffce0000000000000000000000000000000000000000000000000000
That's nothing, dont worry about it.
CPU Miner is calculating the target difficulty in two phase, first a rough guess and if rough guess was positive it calculate it's precise target difficulty. false positive means first phase was true and in precise check it become false.
all in all, it is normal. All users have it but dont see it because their debug mode is off.
