8 ASIC Erupters generating random errors

Above is an example of what I am getting irregularly. I was wondering if anyone might know why this is happening? My setup is a Rosewill 2.0 USB 10 Port Hub. I'm on Win7 x64 and have everything installed properly after following the setup guide. Below is my .bat file.


cgminer-nogpu.exe -o stratum+tcp://us-east.multipool.us:8888 -u withheld -p withheld --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COM6 -S //./COM7 -S //./COM8 -S //./COM9 -S //./COM10 -S //./COM11 -S //./COM13 -S //./COM14


Also, can anyone explain why cgminer 3.10 doesn't work with the -S tag and I'm required to use cgminer 3.1.1 ?

Thanks.

All ASIC mining gear does is guess random numbers called nonces and then hash them (with the block). As there is no error correction in ASICs (unlike GPU's, which can correct errors on their own) some of these nonces will be calculated/hashed incorrectly, resulting in a corrupted hash/result. The ASIC doesn't know what to do with this malformed/corrupted result, and just submits it to CGMiner, which catches the error and shows you that message. If I need to clear up anything else, just PM me. I'm happy to help!

That actually explains everything. Thanks!
