On a side note, if one wants to do escow on a small (<1btc) transcation, how would be the best way to do it?

Topic: Hacking a BFL Jalapeno to 32GH and beyond....(???) - page 18. (Read 54341 times)
Yeah sorry didn't look that closely -_- I flipped over my 3rd one and just set a stock heat sink on the bottom no thermal paste dropped from 70c to 54c. I think amazon works in the UK you could try adding chips yourself. Making a mistake hasn't seemed to fry any yet...
Oh good, you're doing this as a service. Means I don't have to :-)Yes, heat sink makes a diff, but try the thermal grease and original case. Case gets very warm but temps stay around 60c or so with 5 chips. Not bad.
I wish I could get my "immediate delivery" jallies, but it looks like it's gonna wait for a bit...

Yeah, mine's a pretty recent machine, so the chips are probably shitty compared to the stock-7GH one. It seems stable around 5.9GH at the moment, running about 5C hotter than the default.
Getting chips added is probably impossible here - I'm in the back end of the back end of nowhere, and people just don't have the skills. Or I don't know anyone that does.

Sir, please read post #127, I offer such a service. If you're in the continental US this would be very quick. Go back a page and look at my work too, I'm very happy. Also take the sides off your case it helps a lot!!
Please look at my username. See the last two characters? That should give you a clue that I'm not in the US.
My machine is running caseless - the stock fan is replaced by a Noctua fan, and the only other thing is the original rubber feet from the case are stuck on the bottom of the PCB. That sits on a ceramic tile which soaks up any residual heat coming from the bottom of the Jalapeno's board.

Sir, I'm going to try to say this as simple as it is. You open Atmel studios, open the 1.2.9 FW project. When it's loaded you click the build tab/build solution and it compiles. Click the tiny picture of the chip with the lightning bolt. select the AVR dragon the chip on your jalapeno AT32UC3A1256 then jtag and apply. If it needs to update let it. Go to memories erase the chips and reprogram it should have the FW file loaded there already. 2 minutes later you're done, you can run the jalapeno with the JTAG attached.
This I'd tried....
P.S. you need to define Little _Single instead of the usual Single. This file is in I believe STD_DEF.h right after you open the FW in Atmel studios
This I didn't know about...
So, did as you said, and it's now hashing away merrily at just under 6GH and rising. I'm a bit disappointed that it didn't go straight in at 7GH or so...is there anything else I needed to change?
As with my jalapenos when they shipped they had the 1.2.9 FW installed already. It will hash as good as the chips so your chip grade makes a big difference. Your best option is to get a few chips added. At $50 a chip above thats a good price. You can play more with the FW like change I think it's intensity right around line 100. People have reported the best at the stock 7 though.

Ok, I know there are a lot of people reading this for every snippet. One of my rigs is doing 16 Ghs at 35-40C right now, and I've mounted 5 of my chips with no problems so far.
I've been thinking about offering my service free of liability of course. These tools can be expensive and if you aren't familiar with some aspects it can end horribly real quick.
Services I would like to offer
-Firmware Flashing 0.02 BTC
-Adding a chip to board 0.03 BTC EACH
-Adding a custom sink on bottom 0.02 BTC
This will all be at your own risk, if I finally bump something wrong don't try to sue me. You will supply the unit(s) shipped to my door with return label printed already. Depending on further mods you will supply the chips thermal paste and heat sink if wanted. If you want to run 4+ chips you need a heat sink on bottom. I will supply thermal pads, flux and tools. I should be able to ship everything back within 48 hours. (I say this just in case I already have plans that day) Send me a PM if you're interested, I take great pride in my work, and I owe this community a debt for everything it has given.
I'm fine using escrow if anyone would like I've been there.

Helldiver: If your chips are the little ones, then you probably have 1.2.9. Remember you have to compile it with LITTLE_SINGLE, and it doesn't fit in a 128mb chip.

I did try 1.2.9, which I downloaded from somewhere. I don't remember where. My Jally has the 256Mb chip OK.
Could some kind soul post a .bin or .hex of 1.2.9 that I can just flash on that'll make my Jally go faster?
Or, how can I pull the firmware off my other factory 7GH Jalapeno and put it on the 5GH one? They both look identical hardware-wise (both November '13 builds).

Just contacted Magnagen and have a deal in the works to test, I should be able to get some chips shortly. So far it looks good.

@MagnaGen... pm sent. Wondering if that price includes shipping?
Ive got 300 BFL chips in hand, willing to sell them for 0.05 btc each or will trade for Blue Fury / Red Fury Miners
PM me if intersted, Escrow OK!
thanks

So I have a new Jalapeno. I blew on the 1.25ck firmware, then the 1.26, then the 1.29. None would work. Ended up having to go back to a firmware someone was kind enough to supply off IRC. Apparently my Jalapeno is a "2nd generation" one and doesn't work with the older firmwares.
So, how the heck do I overclock this thing?

Long story short it has been written in atleast 2 threads..... You have to reflash your firmware with an AVR Dragon and a jtag cable. you can edit the firmware as you wish. To actually increase the speed you add chips. Most units now ship with 1.2.9 FW so it depends on your chip grade......

That board looks so clean...... God mine's looking like hell by comparison.
Please if you can figure out which leds on the back coorespond to which chips, I'm still curious as to which of mine was screwing up the lower CSEL lines.

I can tell you in the picture above the circled led that isnt lit is the other side of the cross pattern I did. As for the others it would literally be following them around in a circle and the center two are where they meet and touch. I think thats enough info, if you would like me actually figure them out and number them I could Prolly do that too, just not positive about the corners.

OK guys, heres a quick summery as we look at what BFL has done, and of course what I have done.
The pictures care a lot of detail BFL now points their fans down right out of the box.
They started cutting down the heat sinks. (I could guess why)
My 4 jalapenos were clocking at 30Ghs or more, out of the box....
Screws no longer travel the whole length and no silly washers.
What I have done is simple and both of the ones running 4 chips are steady around 40-48C with the fans on. A lot of heat is dumped into the board and through the bottom. My 3 chip with no bottom sink will burn me probably. Easiest best addition ever just ordered 3 more sinks......on back order from bitcoinstore.com guess they don't stock a whole bunch.
P.S. I blew the breaker in my apartment half a dozen times, if you can don't mine and solder on the same breaker......
