Hey everyone, hope you're all doing well. I'm trying to clear up some curiosity I have regarding something I found in the "CGMiner API Log" on my Avalon miners, specifically the 921 and 851 models. There's this value labeled "CRC" that pops up among all the info about the miner. Can anyone explain what it means and what I should be looking for in this data? Like, I see something like "CRC[40 0 1296 0]". What’s that all about?
Well, this applies not only to your miner, it generally refers to the method of detecting errors in data transmission over the network through the use of checksums. In general, a CRC error indicates that the data transmitted over the network does not match the expected value, indicating that an error occurred during transmission. This may be due to a number of factors, ranging from noise during data transmission, deterioration of signal quality and ending with data corruption during transmission.
Upd: As for your case, it is most likely a communication error that occurs between the ASIC miner and the control board.
