(SOLD!!) [WTS][EU/FIN] Antminer S7, batch 9 - 0.5BTC +shipping

edit2: SOLD!!!

~~edit: reserved to a possible buyer at the moment. I'll update this if he doesn't buy the miner.~~

I'm selling 1pc Antminer S7, batch 9.
Price: 0.5BTC plus shipping.
PSU is not included.

The miner is in good shape and working nicely with reasonable temps.
At the moment I'm reading 69, 64 and 68 degrees celsius for the hash board temperatures.

The miner is undervolted and underclocked at the moment, so I can use it with the Enermax Revolution87+ 1000W PSU.
It is also little more quiet and power efficient with these settings.
Here are my current settings, power measurements (at wall) and the avg. hash rate:

Quote

Meter: HT Instruments HT7011, with custom test setup

Antminer S7, 640/670mV, 4.223Th/s (60 min avg), 625 Mhz

Power supply: Enermax Revolution 87+ 1000W
Voltage: 227 VAC
Current: 4,7 A

Power (at wall with the Enermax PSU): 1066,9 W

Everything has been done carefully according to sidehack's hardware manipulation guide (see https://bitcointalksearch.org/topic/hacking-the-s7-improving-efficiency-through-minor-hardware-manipulation-1504228).
I can also revert these changes and set it back with the original settings if the buyer wants so.
