I picked one of these up second hand - only three days ago - not impressed so far...
1. the small heatsinks fell off
2. last night I smelt a burning smell - the 2x molex to 8 pin pcie power connector (shoved in a 6 pin socket) was burnt - traced it all the way back to the PSU (toughpower 1500w) theres one burnt peripheral socket now.
At the moment im running two modules that I have stuck heat sinks back on - the other that was pluged in to the fried socket im reseating (
with this) the heat sinks delibrately.
The chips seem to all be a bit melted when you remove the small heatsinks.
Can see why he was selling it cheap.
running 4 modules at the moment ~830 GH/s at ~897 watts
Now, a real question. How do you guys easily measure the powerusage of your mining hw?
like thisThough I wuss out and put eletrical safety gloves on to throw the switch and press the buttons - I dont trust these cheap chinese contraptions.
Also dont trust them enough to leave them in for a long time - put it in - see watts - take it out.
