Hi I have been mining for about 6months now. I mine through BTC Guild and for the last 5 months I have been using 12 Antminer S1 @ about 2200 GH/s, but about a month ago they started disconnecting and reconnecting then stopping for several hours, then starting again my speed drops to 500GH/s Then up to full speed then back down again. There is no pattern to what they are doing it happens day and night my charts of mining speed on BTC Guild is all over the place I've logged in to the machines and the are all running about 39-40 C no dead chips. I have virgin broad band (fibre optic ) running about 50Mb. Does any body know why this is happening.
Regards
Peter
Do you have any logs or anything with around the times you see the miner disconnecting/reconnecting as there maybe something in there that will give an insight to what is happening?
Also what is your Accepted/Rejected ratio like?
