plz make "how to" step4step frob back up to chainminer upgrade manual for noobs like me)
ChainMiner for M Board Version 2.X boards DO not use this guide for Version 1x m-boards. It will fry your chips. This is only meant for Version 2 of the M-board.I apologize for grammar as I took 2 sleeping pills and I can barely feel my fingers. 1.login as pi or root 2. type "nano /run/shm/.stat.log" if you wish to see the performance of all the chips on your board before upgrading chain miner. (optional step) 3.(backup your chainminer version) (this creates a copy of the folder) a. sudo cp -a /opt/bitfury /usr/bitfury.backup b. cd /opt/bitfury/ c. pwd (make sure you are in /opt/bitfury) d. ls -al (or type dir) e. rm -rf chainminer (this removes everything in the chainminer folder) 4. make sure you are in the /opt/bitfury directory and not in /opt/bitfury/chainminer (it should be deleted anyway 5. type "git clone https://github.com/bfsb/chainminer.git" 6. it should now start getting the chainminer git. 7. now type "cd chainminer" you should now be in the chainminer directory 8. type "make" 9. Its going to take 5-10 minutes to create the chainminer...maybe longer. I got some warning but everything was fine after it all finished. it will go back to a bash prompt when done. 9a. Just wait...this is the longest part of doing this change.. 10. sudo reboot very nice! thank you very much! )

verkaufst Du H Boards 1 - 3 Stk. auch einzeln ?
nope

hallo an alle, wollt mal wissen was die farm euch wert wäre. inhalt: 1xM-board(mit raspi), 10xH-boards, 1xOCZ 1250W netzteil, selfmade gehäuse mit 3x140mm low noise fans mit drehzahl steuerung und temperatur anzeige. pencil mode ~1.2kOhm, 10x3mm kupfer platten. back temp ~36C surface temp ~45. läuft mit 280-295ghs stabil (autotuning ON) deswegen schankung, die meiste zeit aber im 290er bereich. noncerate[GH/s]:291.256 (1.879/chip) hashrate[GH/s]:299.575 good:20344 errors:412 eure meinung bitte =) mfg

d) Pencil mod the board until voltage reaches 0.8V. One of my boards is at 0.8V another at 0.84V. I would say 0.85V is the max after which either the regulator will shut down or the hash rate will drop dramatically. how many is it in ohm on resistor? i usually donot measure ohms, I measure the output voltage of the regulator. But I think it should be between 1.05 to 1.08K on the mounted resistor. what about the area around the chip? you think this copper heatsinks are enough for dropping temp? ... how high is temp actualy? =) sorry my english soo bad^^

hi all, how do i connect to miner from iphone ( i am not in my wlan, only 3G)
you need to port forward your miner's port 80 outside the NAT, or create an ssh tunnel into your home network if you have a server with ssh port open. and get a dyndns.org address to your home ip, as its ip address might change. Put the dyndns details in your router, and you will always have minerXXXX.dyndns.org as your connecting point to your home network. I'd recommend having some sort of VPN firewall setup if you really want to access home from outside.. thanks! ... now another question ... @10 h-boards we got 160 chips in stat.log ... why is there only 150?

Both are working on eligius, 60gh @diff 128, 45gh @diff 64. I tried 256, but it fell down to 30gh for 2hours tonight.
diff 128 too much for 60gh i think ... 8-16 is nice.

Bank 1 1: 30.781GH/s 2: 33.315GH/s 3: 30.022GH/s 4: 0GH/s % of HW errors? or ... show your stat.log please

Guys heads up on pencil mod for overvolting and thus aiding overclocking.
Use pencil mod on R2F, make it around 1.1 - 1.2K, voltage goes from 0.66V to 0.81V. The default value is ~1.3K. It may blow the 30AFuse if you go too high; so make sure you do it only if you have a soldering station handy After Mod (I have only 3 H cards ) Bank 1 1: 30.781GH/s 2: 33.315GH/s 3: 30.022GH/s 4: 0GH/s how to? risks? pics? =)

sooo ... now i have chip.cnf with not tuned lines in and best.cnf with auto tune on selected chips only ... i start from webface new ... which cnf ist now in use?
|

I'm raising or lowering the speed of the chips, depending on the number of errors. I have also turned off the autotune. The point of manual tuning is that it works a little bit better than autotune. Let's take the first chip as an example. Autotune is on ( AIfDSo). It can be turned off by changing the capital A to a normal a ( aIfDSo). Now the chip will always run at the speed you have set. Current speed is 55. Minimum is 52 and maximum is 57, higher the better of course. In this case I would raise the speed to 56 since there are practically no errors. Chip two: change the "aifdso" to "aIfDSo" and let's see how it does (it won't work at all with aifdso). Chip three: Something wrong with it. Turn off the autotune and keep the speed at 52. At least this is what I would do because 0,6 GH/s is still better than 0. More info here http://punin.com/README_BFSB_v0.1.txtthank you very much! =) ... (every time i fall in this trap, read teh fckn manual)

Here is how I tune my chips manually: - SSH into Pi (login "pi" password "raspberry"). - type "nano /run/shm/.stat.log" - I'll edit the file and when done, press Ctrl+X - It will ask "Save modified buffer" and I press Y as in yes. - Now it says "File Name to Write: /run/shm/.stat.log". Just erase the whole file name with backspace and type "/opt/bitfury/best.cnf" and hit Enter. - type "sudo reboot" what exactly did you edit? "2 AIfDSo 55 1.432 1.596 100 1 0 0 151 [0:1] 227 6 6 6 6 6 7 6 7 7 7 6 6 6 6 6 6 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0" --- good chip "14 aifdso 54 0.000 0.000 0 0 0 0 0 [0:D] 756 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 " --- bad chip "31 AIfDSo 52 0.616 1.216 43 39 0 0 115 [4:E] 482 3 2 2 3 2 2 1 4 4 3 4 3 3 3 2 2 2 3 3 2 3 3 4 1 1 3 2 2 2 2 3 3" --- whats wrong with him?

PSU considerations:
We also found a noticeable voltage drop on the IOVDD chain when all 16 cards are plugged in (down to 1V66 from 1V8). This will get fixed (hopefully) in next revision on M-boards, that is already in production. This should help lower the errors and noise on Bus D.
this mean rev2 m-boards are not ready for full upgrade?
