No both bricks work for the 3 chip version. The 2 chip has 29 shares accepted and 57 HW errors. I can grab the BFL driver I guess but BFGminer is telling me a pretty close speed of each chip as well. So far I'm extremely disappointed in BFL blackfriday product seems like their unloading the shit inventory. I'll have to check the 2 chip board rev. but there is no tag saying inspected or shit....... RMA if I can ever get a hold of them rofl, eBay has a better RMA policy for selling defective products... Thinking I pretty much lost my money on this deal.

I'm in a state of shock, but it's from a different bitcoin thing, so at this point nothing will surprise me.

In the meantime the BFL commport thing was written by Red_wolf, and it's probably the most useful thing in the planet. Let me find the link.

He made a bunch of versions, start at like page 4 or something. It's really useful.

Is this in the driver pack that BFL produced? Never really needed it, but I guess if it provided some more info. As for the speeds there are 3 lines speed 1,7,9 I just need to turn down speed 7 a little lower for more stable performance maybe?

Ah ha runs at speed 1 only about 7 Ghs will bump up as possible. They wont even start if to high? Shitty chip grades? update will only run with speed 1.............................

Christ, maybe they scraped the total bottom of the barrel and used three Z grade chips. I have noticed that if you set the max frequency too high that chips may not fire, never seen one so screwed up it wouldn't start on 7.

That's kind of cool actually. Just saw your image, holy fuck it does have three chips enabled. That's cool!

Try speed 3,5,6 and see if it comes up a bit faster. One bit at a time. If you load up the BFL comm tool you can actually see what the chips are hashing at, which could really be interesting.

128lb ones can be flashed, I think eoakland figured out you have to set the compile option in the code to be for a 128kb chip. It does work, but if you don't do that you brick. And sounds like one of your bricks is crap, cool.

After running for over an hour @ speed 1. One chip is really slow on submissions and another high with HW errors. Leaving it for now going on to the next jalapeno......

Load up the second one in atmel studios and it's a 128kb version..... Those wouldn't accept the 1.2.9 because of the size right? Just want to check before writing a file that's not going to fit. It also just slow flashes the power LED if I use a brick. Only will power up fine on my PSU.

Try using a low speed like 1. Also what do you see with the Handy Dandy BFL Commport scanner?

Ok, so interesting findings. I took the 3 chip jallie and flashed it with 1.2.9 after editing for "little_single" it boots up and registers 1 chip.... Like wtf?? Hashing at 2-3Ghs I've went through and flashed it about 4 times checking through std_def.h. I'm kinda at a loss with this again, Why would flashing cause only one chip to show??? Pics to follow prolly tomorrow.

P.S. the FW version written on back is 292..... hmm board rev. C same as others. This has to be a FW issue somehow....

Really busy with the holidays, but Merry Christmas or happy what ever you celebrate. So I got my 2 new jalapeños yesterday thank god. So I watch them for the first day mining one at 7Ghs with 4% hw errors and an 8 with 2% hw errors. So I'm like wtf and start looking at the boards. One has 3 chips on it!!!!!!! I started geeking out wondering why it wouldn't be initiating when it's obviously recognized. Figure it's prolly clocked down and I'll be reflashing after the holidays. Just wanted to let you guys know, only one of them has 3 chips. Dissect that.

Enjoying Christmas here. Fortunately my shipment is stuck somewhere in Kansas, otherwise I wouldn't be playing with my kids and all. :-)

So BFL's switched over to three chip jallies. Very. Very. Interesting. Did you happen to order the 2gh bump-up?

Which way is the fan blowing? And of course pictures would be cool.

Finally!! A tracking number and actual shipping information on my order of 4 Jalapenos from the black friday sale.... It does look like BFL decided to copy this forum idea with their new 10Gh/s Jalapenos.... I'm wondering if they are 3 chip or 4 chip units and I'd like to see what additional cooling options they've used.

My units are stuck in Kansas since Sat. So I have to spend Christmas loving my family instead of like scrooge with his gold bitcoin miners....

I am going to guess it's 3 chips, clocked to speed 4 or so which will run the chips at pretty low power and low heat. I've done 3 with the stock heat sink and case; temp goes from 35 to 50 or so.

Going to 4 requires some more firepower. 5 requires a heat pipe sink to fit in their case (and the case starts to become a heat sink in it's own right). Not sure about 6 or more....

Recently had a jalapeno experience fast flash of the red led... one of the original chips was the cause... error cleared when I pulled the associated chip... that chip to led map is a lifesaver and should be blown up, cleaned up and reposted as a separate entry here on the thread.

Congrats on fixing it. Did you put another chip on?

Merry Xmas to all.... ordered myself 2x more antminers today... guess I'll use the 4 Jalapenos for altcoin when they show up

Lightfoot, just order the 0.5mm balls and manually place them on the chip to re-ball it. Better ROI.

Tried, damn near impossible. Spent $10 on a set of stencils and a cheap holder (the $2 one). Will try that in Jan.

So it looks like ButterFly labs is getting into the jally-jumping game.

They're advertising a new 10gh jalapeno. Which I am betting involves boards with three chips on them, not two. If they run the 3 chips at a lower clock speed they will reduce heat, and could run them on existing equipment.

Josh did you get the idea from here? :-) If so call them "Lightfoot's revenge" or something like that.

Oh I did also chat with that Ebay seller; he's fixing the auction so he can do international. I'd say give it a go.

C

1) The auction at the original link still says continental USA only. Is there another auction/link?
2) According to the photo, the chips aren't native BGA, but a chip on a PCB with balls.

The ones I got are the later ones which are slightly lower profile than the early chips, which were on a little PCB board to turn from from QFP to BGA. The only early style chips I have ever gotten were three "demo" chips from another vendor.

Either will work. Try messaging the seller, he'll work it out (note I have no relation to the seller other than being a happy buyer of 4 a few weeks ago. Got them with no problems, waiting on a few more)

Well, that makes two failures of trying to re-flow chips on a board that came off other boards in "odd" condition. I clean the chips, remove the solder with an iron at 750f, flux, and desolder braid, put it on the board, center, and give it 350f low temps and 450c temps for 2 minutes. Same as the other chips which go on fine.

Fail. Tried adding flux and another 2 mins, fail. Drat. Fortunately this is on the junky jally so I wouldn't mind if it were trashed. But it did not work :-)

I'll debate just buying chips over trying to continue adding these. They could have been wrecked by the previous owner, but to be honest these chips seem to take a lot of heat and work. I guess I could spend $70 for a reballing kit, but the value is kind of eh.

I'll wait for the new jallies to come in before trying to put on my last 5 chips. Should be Christmas eve, I wonder if I can put up a big sign saying "JUST LEAVE IT WITHOUT A SIGNATURE DAMNIT!" or something like that :-)

Well, I boosted a friend's jally to 4 chips. Here is my thoughts:

3 chips: Warm, from 38 to 50+. Do-able
4 chips: Holy crap it's *HOT*. 80c, throttling with my BFGminer.

I now have an old AL heat sink on the bottom plate (secured with thermal grease) and a fan on it from the side, will see if it holds. But running a jally with 4 chips and no bottom sink is not a good idea IMO.

I also think I need to take the top off this thing. But 15+gh, no problem with the chips. Flux on the bottom of chip and on board, thin coat, set the chip square, review with a loupe, 350F pre-heat for 10 mins, then 450c at low air flow at .25 inches off the chip for 2 minutes. Done and done.

Edit: Taking the top off and letting the fan breathe makes the difference.

Yeah... "Does not ship to Poland" Sad

Who, Lent? Send him a private message, he seems to be a good egg.

C

I'm also interested, but he wont ship to Canada and I cannot even message him on Ebay (it wont allow me somehow?).
Do you know if he's on this board and what nick?
Thanks.

That's odd. I can email him myself and ask if he will ship to Poland and Canada. This is a big world of course.
