Re: [HOWTO] flash your jalapeno to 8+ ghs

I flashed two jalapenos yesterday with the 1.2.9 firmware.

Got some strange results on both:

These two shipped together in one box, I bought them used. I'm guessig they are fairl early as the heatsink leaves room for the jtag cable.

they have 1256 chips not 1128.


The first one I flashed without making any changes in the firmware and it hashed at a steady 3740...

So I went back into the files and changed it from a single to jalapeno in the std_defs.h.

It hashed at 6745, 7740 and 8812 cycling between the three exact rates.

I went back in and altered to a little single and nothing changed.

So I went back in again and altered it to a Jalapeno and the frequency from 33  to 64.

Tested it and it now cycles between 7891 8898 and 10126.

Used the exact same build on number two and it cycles between 6665 7490 8812.

Wondering what is going on and what I did wrong?

Hardware errors on both after 24 hours are low 76 on the first one and 188 on the second.

They are not in the cases and have a 120 mm case fan on top of the heatsink. Before flashing they ran at 33 degrees and after they are running 41.
