Me got no pi, no 0.4, no 4.0.1 that sees my BJ
Then you in serious poo
Actually, my BabyJet is hashing about 400 GH/s when overclocked between 600 MHz and 612 MHz. It would probably be more, but it keeps disconnecting every 10 - 20 minutes. Fortunately, the hotplug feature in cgminer 4.0.0 finds it again within seconds.
I've Emailed HashFast a couple of times about the Pi. My latest Email was about simply sending me a firmware loader.
All of this has given me a chance to brush-up on my *nix skills. I haven't messed with this stuff in 20+ years... It's actually been kinda fun. Twenty years ago, there was no such thing as github...
Just a suggestion since you have the programming skills - why not try one of the programs to emulate the RPi on a desktop while you wait for Hashfast to never get back to you?
This one seems promising: http://xecdesign.com/qemu-emulating-raspberry-pi-the-easy-way/
650 = 450 gh/s
687 = 480 gh/s ( the best I get)
700 = 460 (I see it getting Blabber out of 2 dies ) which causes it to not work efficiently

Interesting, I also got my best OC at 687.
How much power are you drawing at 687?
Yes, somebody (not me) received their kit but it came without any instructions so he is still wondering how to hook it up
Here is a picture of the current setup:

Looks like they have the "chain-up/chain-down" ribbon cable AND the USB header connected on the bottom board - should be one or the other. If they are having trouble, this may be the cause. Tell them to disconnect the black 5 pin USB header next to the ribbon cable on the bottom board (not the 5 pin WHITE stand-by power cable.) The ribbon cable makes the 2 boards into 1 800Ghs machine vs. the USBs making 2 400Ghs machines.
EDIT: Also, the white connector only needs to be connected to the last board in the series so it can be disconnected from the top board.
(While we're at it, can someone tell me the colors of the wires (under the black sheathing) on the white connector - back to front? Thanks!)
Guys, I asked about the upgrade kits and MPP and was told there were no MPP or upgrade kits ever offered in batch one. So apparently just because your BJ system was batch one, doesn't mean additional boards would be in the same batch.

I am NOT "shooting the messenger" (nor am I in Batch 1) but what they told you seems to directly contradict what is CURRENTLY posted on the Hashfast website MPP page:
"At HashFast, we understand that healthy, prosperous customers make for a healthy and prosperous company. We know that our customers are concerned about the rapid growth of the network hashrate and we stand by our customers. We designed our silicon so efficiently per square mm, that we are able offer you this protection. If the Bitcoin network hashrate increases so that your Baby Jet doesnt generate more Bitcoins in ninety days than you paid for it, HashFast will give you additional ASICs. In fact, we will give you up to 400% more hashing capacity than the Baby Jet you purchased. Yes, that does mean that if you dont make your money back in 90 days, we will increase your mining capacity to up to 2 Terahashes! The Miner Protection Program was given retroactively to ALL purchases of Batch 1 Baby Jets. For second and third batch machines, the Miner Protection Program was offered as an add-on, that customers could purchase for an additional fee. Currently the Miner Protection Program is not available for purchase."
So, while they may not have been "offered" at the time of purchase, ALL Batch 1 orders should be covered by the MPP since they were "GIVEN RETROACTIVELY."
Or am I misunderstanding something?

Is this the Cable we need to chain BJ boards together?
Thanks
No, that is a 2.54mm pitch connector, whereas the chaining connector uses a 2mm pitch. I think we use a Samtec 2x8 IDC connector in the cables.Is this the Cable we need to chain BJ boards together?
Thanks
It's the same pitch as the old 2.5" laptop IDE drive cables were. So if you had one of those laying around, you might be able to cut it down. (They were 44 pin IIRC)

How about these: http://www.ebay.com/itm/10pcs-Flat-cable-connector-2mm-0-079-IDC-SOCKET-16Pin-2x8Pin-/291060588602?pt=LH_DefaultDomain_0&hash=item43c490203a
Then we just need the ribbon cable. A bit of D.I.Y.
Once you have that, simply mount the second board, connect the chaining cable from the top to the bottom board (using the 2 closest 16 pin connectors), MOVE the 5-pin cable to the second board, and then connect the spare set of PCI-E cables to the new lower board.
-Phil
So, when daisy-chaining boards together, the 5 pin power connector needs to be attached to the LAST board in the chain?
If multiple boards are being supplied with enough power, how many could be PRACTICALLY chained together?
Read through HF-Engineer's posts, they've been very helpful.
Thank you. Would you please let me know where I can find those posts?

Thank you, sorry, I am really new. By the way do you have any HASHFAST rigs running?

Would someone who has looked inside their HF please tell me what color the wires are on the white 5 pin Auxiliary Power connector are (back to front) - it's the one near the USB header on the motherboard.
Mine hasn't arrived yet, or I'd do it myself.
TYIA!

spectre2112: I'm not sure what aux connector you are referring to. If you can attach a picture, that will help. If it's the 5-pin white connector, that's the one that provides +5v standby power to the board, and also enables the board to turn on the PSU. (+12v)
Yup - that's the one!
If the connector is in the upper left corner of the board, what is each pin? Which is the +5VSB, GND, etc., etc. and etc.
Thanks!
(I ask because I'm sure I'll end up modding in the future.)
What can you tell me about the "AUX POWER" connector?
Is it the same as what you'd use for a 3.5" Floppy Drive?
I take it it's connected to the power supply - not somewhere else inside the case?
I see it's a 5 pin connector, but most of the floppy drive connectors I see are 5 pins but 4 wires; what does this one have?
Thanks for the info!
