I will sit out this round but I'd like to get at least 1 more Avalon 6, probably next round if Philip will do another group buy.
By the way, I figured out why my a6 was having problems, it was my old corsair rm1000 PSU, as soon as I replaced it with two server psu's, it stabilized and it's hashing at 3950 ghs. So, make sure you have a good power supply at least 1200 Watts, set your A6 at freq 500 and fan minimum 40, as suggested by philipma and others. Do not exceed voltage over 12.3, or your a6 will burn up. I had one of my Bitmain S7 go up in flames, it couldn't handle 12.8 volts, so it's normal for these miners to burn up if you overvolt it.
yeah these miners can be touchy
