Title: dead bfl fpga
Post by: candoo on June 03, 2013, 07:21:21 PM
One of my BFL FPGAs is dead. It is one of the units with 1.3 Ghashs.

Only the LED next to the power connector is activ.  Maybe its just a dead fuse? Did anyone had that kind of error? The chips dont get hot or anything. Its complety dead. (the fan runs)

Have you got access to a multi-meter?

That would certainly help if totally dead, but power still supplied to a running fan...

Minirig units are 1.2-1.5gh/s.

They're called the "BitForce 2.0 cards"

I wouldn't doubt it. I sold some for 100btc each a while ago.

Never used silk road though :P

weird
honestly dump it, it just got more expensive mining with it than electricity probably.
