Strange rejected hashrate
I generally run two A2 terminators on prohash. I do however have some Farmboys from Innosilicon and today I tried to connect up with some of them (there are several farm boys in one control unit). The two A2 terminators run fine, but if you see the enclosed graphs there are some enormous spikes from the farmboys. They should produce around 210 or so MH, but suddenly I got rejected hashes up to 6(!) GH.... The only setting I have on the farmboy is r=1.2

Re: Strange rejected hashrate
Which worker are the new miners? Your shares are being rejected for "Miner is using an incorrect algorithm," but all that really means is that the data being submitted isn't a scrypt hash. Looking at the logs, the rejected shares aren't even hashes; they are just submitting the text "false" However, if I limit my search to shares from the same IP address as where the rejected shares are coming from, I see plenty of valid shares, so the miners seem to be working.
I'm not that familiar with the Innosilicon Farmboys. Would you be able to post the log from the miners so that I can see what is happening when the hashrate is rejected?
On a side-note, all that matters for your earnings is the accepted hashrate. I wouldn't put too much concern with the rejected hashrate. The rejected hashrate is just an estimate assuming that computing a rejected share requires the same amount of work as an accepted share. Since rejected shares don't actually require any hashing to be done, your miner could submit rejected shares as fast as it can upload and get an infinite rejected hashrate (of course, the mining server would temporarily ban your IP address before then). We may need to change the method in which we display the rejected shares so that it doesn't overwhelm the charts.

Re: Strange rejected hashrate
Thanks for your reply. Yes I will post the log but its on a remote location so I will not be able to do it for a few days. Here are some technical specs on the farm boys:
