Hey guys. Here today to offer up a lightly used S4+ (shy over a month). If your'e trying to get a hold of one but can't, here is your shot.
A little back-round on my particular unit... as i hear its "special" (I only say this as iv'e not seen anyone acquire this hash-rate with this chip speed)
-It is currently averaging a hash-rate of 2,725Gh/s with an average temp of 75C. This is being achieved at a chip speed of just 212.5! Voltage is locked on S4+ so that has never been played with. Temps never rise into the 80's and that's with this unit in an enclosure that's around 90-100F ambient. I haven't had any issues with this unit shutting down nor any asics going down. The longest up-time iv'e had is around 10 days or so, this is due to the unit using my electric dryer circuit and me needing to power down to dry my clothes
-Otherwise i have no doubt this unit would run endlessly just as my S5 did in the same conditions. I will say in open air with ambient around 75F the unit tends to run at or under 60c so i hit the silicon lottery with this one.
*edit*
Forgot to mention my hardware errors average 0.0002% at the above mentioned hash-rate/chip-speed. It's also interesting to note that at stock chip speed and a lower temp the hardware errors averaged 0.0008%.

Asking $1,300 shipped. Some may object to my asking price. To the uninitiated, hop on ebay and see what they go for now as they are disappearing from the internet. There is only one and it's listed for $1,900.
