Re: Hacking a BFL Jalapeno to 28GH and beyond....

And in the really interesting news, I had a unit come in with a power supply that went *bad*. Jalapeno, ran it with 3 chips, checked in and saw that it had a massive amount of errors going on. Shut it down, put it on the bench supply, worked fine. Tested the power supply and I see 60 volts between negative and AC neutral.

Glad I have an isolated power supply on my miner. I'm wondering: Does BFL want the old power supply back when they RMA, or will they just send a new one out? I would really like to "interrogate" this one and see if it has the same blown caps as the one from England.

Good news: No damage to the jalapeno. In fact it's now hashing at 14gh with a second added (client provided) chip, much better than the 5.4 it came in with (it has two lousy chips on it and two very good ones).

I've heard both... apparently the right and left hands aren't talking... so maybe it depends on if you are wearing matching socks and Mars is in the shadow of Venus...

I honestly can't see them needing the PSU back, it's not like you could fix it and reship it.
