[HOWTO] flash your jalapeno to 8+ ghs

[lightfoot]

is that really possible? I mean just put chips and they will work right away?
chips are not so high priced - and we already have all in place - if you could really do it it would be at least awesome )

At least one person has done it, you need to upgrade your power supply as well with 4 chips, not sure what hell will break loose with six.

The trick of course is soldering BGA; I have air tools, but have never quite done this. We shall see...

The problem you might get it the heatsink with the extra chips, I don't know if the Jalapeno heatsink is the same one as in the Little Single, investigate that before loading up the board. Also check if the regulators are the same.

my late model little single 25 ghs (came running @ 31 ghs right from the factory) has the aluminum HS and my early model jally 5 ghs (flashed to 8.3 ghs) has the heatpipe HS. go figure.

gonna swap em soon as I get the chance flash the little single..

so you can get away with 8 chips running near flat out and the aluminum HS with good airflow.

I would worry about cooling the rest of the components on the board more.

In looking at my LS and Jalapeno, I don't you can swap the heat sinks... The Jala only has 2 screws holding the sink on while the LS has 4.

drag. so much for that idea.

oh well Ill just have to add additional airflow to make up for any extra heat if it turns out I can get more hashes from flashing it. got some server 120 mm fans that would do it.

this stuff runs in my basement so noise and aesthetics are not an issue.

Flash it and you will blow the FETs.

Ive been reading on that (great stuff youre doing with jallies btw!)

I would have crazy airflow if I did it. my ls is probably near its limit stock as it came from bfl (31.5 ghs, its a 25 ghs unit, 1.62% hw errors) so I dont think I could get much more.

what I would like to do is tune it better, like clock down marginal chips and boost hardier ones. keep the power draw as near the same as I can.

cgminers latest version says it will give nonce and hw error reports per chip now. might be possible to tune it pretty fine.

heres a question.. if a FET blows, does it take anything else with it? I would have no problem replacing FETs.

Hey Guys,
i had some problems flashing a new Jala which arrived some days ago.
Is there anything new?

Ok, you're aware of everything. :-)

Depends. I have never gotten a toasted one to fix, but I am guessing that what happens is the FET shorts and the power supply fuse blows. Damage can be fixed by taking off the heat sinks, identifying the blown fet, pulling it, checking the 1 volt line for shorts, checking the remaining FETs, putting a new one or two on, replacing the fuse in the supply, and going for it.

The problem is the average yabo will stick a 1,000 watt 12 volt supply on the unit without a reasonable fuse to "replace the power supply". Powers up, feeds 100 amps into the short, and the usual hilarity follows. At that point the board is damaged, and one might have to check the oscillator circuits that power the FET drivers. They are probably blown up due to high 12 volt currents goig through the gate lines.

New things? I went back to speed 7 on my Jally even though speed 8 is "faster". Speed 9 causes a total performance collapse. Speed 7 is the best.

I think people with jallies that have only 8 engines running per chip flashed with speed 9.

I've just flashed my Jalapeno (1 Nov build date) with CK's 1.25 firmware, and also tried the 1.26 firmware.  Neither seem to work.  The 1.25 firmware runs but it's showing 500GH with 100% HW errors.  

1.26 it won't run on at all, just flashes it's LED quickly.  

I'm running BFGMiner 3.6.0 on Minepeon, and also tried BFGMiner 3.8.0 on Windows - it just spews out errors.

Any ideas?

You must have newer chips. Flash with 1.2.9 with "Little_single" defined and the other "single" commented out.

Where would one do this commenting out and how?  I am familiar with the bundle of files used in the process but it looks like it is all written in C and I wouldn't know off hand where to mess with it and how to mess with it without breaking it.  I have an actual LS but I have either been unable to get the official release flashes to work (led4 flashes continuously) or they have hashed seriously wrong which is more or less what I here HellDiverUK saying about his Jalapeno.

Whats the difference between the old and newer chips?

[ooxtcoo]

i got my 2 jalapenos ordered in april 2013 today!

one is hashing at 5.600 mh/s sometimes up to 6.000 mh/s (so not realy good)

but the other one hashes stable at 7.700 and sometimes 8.000 mh/s without any modefications.
i think that one got very good chips!

i have 2 asic chips from a death jalapeno, now iam playing with my mind to solder it into the bad one.
question is:

i expect the new jalapenos have the new chips but the death jalapeno may have old chips.
can i mix them?

did someone did this already?

Height and old chips can't use engine 0 in a parallel config.

New ones can.

Yes, however removing the old chips might be even more complex and you will have to reball them. You should sell me the shot jally for $50-$60 or so that I can figure out why it is dead.

i soldering bga's since 8 years in my shop, so no problem to reball them.

the jalapeno have a death motherboard.
i got it with hot ftdi chip.
the ftdi chip was getting so mutch hot that it burned itself into the pcb, after removing the ftdi chip it
lift of the first layer of the pcb.
i tryed to recover the lost tracks with the shematics, but after powering on, in some layers i seen it again
burned the tracks and shorted.

i changed the atmega, ftdi chip, dc dc converter, coil, checked the fets, but it no way...
the pcb is too mutch demaged for repair.
