n00b question: when checking rejects in cgminer do you look at the R value at the top next to your average overall hashrate? or the R value next to the GPU? because in my case these numbers are drastically different (50% reject vs 2%)
I assume its the per card rate, but is there a reason why I'm getting 50% in the top number?
Your GPU values are the correct values. The other R is counting Untracked Rejected Shares as well. Read Terk's explanation a few pages back (p.108).
Cheers.
