Got mine today, been pulling my hair out all day trying to get all 16 boards to hash right. 3 of them refuse to hash over 16-17gh/s no matter what order I place them in.

They should be marked in what slot they should be placed, did you take care of that?

I ordered a starter kit and 13 hashing boards and then a little bit later 2 more hashing boards giving me a full kit. However they were not marked for me, only 2 of the boards where marked.

oh, afaik only the full kits where marked. I could be the case that you are out of luck then for the moment. If you happen to live in the south of Germany, I could lend you a different M-Board to try. You should probably contact BSFB Support.

So far I can say with certainty 1 of my boards is toast, dosnt work, starts off at 60gh/s and drops to 0. got 4 others that don't work well.

u run autotune off or on ?

You probably already know this, anyway, put worst performing boards as last board of each bus.

You have four buses, marked A-D on your m-board.

You can try to set all chip speed to 55 and turn autotune off. Let it run for few hours and check results. If you have multimeter check what  voltage you are runing on the 60->0 GH board.

at the moment there seem to be heavy ddos attacks on major pools, this could also lead to these effects.

Cheers, im gonna run it on autotune for the night. Then tomorrow will try your idea.

Anyone willing to help testing a cgminer fork changes with a full kit or at least one board in each bus (A-D)?

https://github.com/KaloNK/cgminer - in sync with the latest Legkodymov's miner. For BFSB master boards you should leave BITFURY_MUX_OE undefined in bitfury-config.h and change:
Code:
#define BITFURY_MAXCHIPS 100
#define BITFURY_MAXBANKS 1
#define BITFURY_BANKCHIPS 100
to
Code:
#define BITFURY_MAXCHIPS 256
#define BITFURY_MAXBANKS 4
#define BITFURY_BANKCHIPS 16

By default the GPIO pins are defined (in tm_i2c.c) for BFSB boards, so no need to change anything there

I am sending all changes back to Legkodymov, so the changes in mine are just temporary - there are enough forks already, no need to follow another one, but i don't mind Smiley

I would like to connect a h-card directly to my raspberry pi.

Like this board: https://bitcointalk.org/index.php?topic=7216.msg3308020#msg3308020

Is that easy?

probably not

1) you need to get 12V current into the h-board (the m-board holds these connectors)
2) the m-board has its own chips, its not just a replication of the gpio pins

What do these chips do?

i beleive that at least a portion of them are used to drop 12v down to 1.8v for comms, but im not sure. (there are about a dozen devs that could provide a better answer on this!)

Raspi interface (SPI bus and GPIO) work on 3V3 level. Bitfury chip use 1V8.
Chip (TXB0104D) on M_board work as level shifter. Additionally you need DC/DC converter for supply 1V8 to each H-Board.

So far out of my full unit I have one totally fucked up board, 5 chips work, 8 are dead, 3 are so dead they dont even show up in the log.

I have 4 other boards performing terribly I need to try and sort out. Hopefully i can atleast get them to 25gh/s via manual tuning.

Sigh...

punin will replace a board if its totally dead.
i run my boards with autotune and some pencil mode, they do just fine Smiley

In my experience, sometimes a little bit of time running will awaken dead chips or improve mediocre chips. My starter kit originally had a chip that responded at about 0.6GH with 20-40% errors for several days and reboots. However, after a pencil mod, it suddenly began working perfectly (now getting >40GH on the board).

Try doing a bit of voltage increase (0.78V is a good place to start if you have no heatsinks, 0.8V if you do) and see what happens.

for the dead/missing chips, there are some reports on removing its connections to "see" the following chips in the chain. (however, a replacement board is a better alternative if punin can do it quickly)

Since yesterday evening, I am having an enormous amount of duplicates, about 33% ?!
Any idea why this could happen ?
I have been shuffling the boards around a bit, and sure, I could try to revert, but I am also curious why this could happen.
I have one M-board(V2) with 11 H-boards:

Bank 1
1: 24.496GH/s
2: 23.121GH/s
3: 24.61GH/s
4: 18.984GH/s
Bank 2
5: 23.608GH/s
6: 24.954GH/s
7: 24.854GH/s
8: 20.73GH/s
Bank 3
9: 18.955GH/s
10: 21.546GH/s
11: 20.659GH/s
12: 0GH/s
Bank 4
13: 0GH/s
14: 0GH/s
15: 0GH/s
16: 0GH/s

I am not using Bank 4 because the cards don't hash there.

BtcGuild:
bitfury_1   163.18 GH/s   96768 (100.00%)   0 / 33024 / 0

Also the hashrate is all over the place. I have seen boards hashing over 30GH/s, but currently none of them do.

I am selling in stock OneStringMiner boards, based on the Bitfury chips. Have a look here: https://bitcointalk.org/index.php?topic=495536.0
