And how well does that regulator seem to work?

very well in fact. No overheating issues until max 1V that I have tested, but the bitfury chips get super hot, since I donot have adequate heatsinking for them.

Do you know how many amps you're pulling from that 30A regulator? Don't you want something a little beefier like 40A? And is an output side inductor unnecessary for that regulator?

Actually I donot have the testing tools to measure > 10A current. This chip is actually a 2phase regulator with 20A OCP limit per phase. So I am drawing less than 40A for sure. There are 2 0.2uH inductors inside the chip Tongue

. If bitfury will ever reduce prices of their chips, my plan is to get boards built and quickly solder the chips and couple of decoupling caps thrown in and connect this regulator on the outside. No fuss no muss.

why can't you mount the heatsinks on the chips themselves? are they mounted on the backside?

yes there are heatsinks on the backside as well. I guess I need to source beefier heatsinks to test the board at >0.85V

So about 12 hours ago my bitfury miner stopped.

I was wondering what the hell happened. I thought it was my cards or SD card again.

turns out I can mine on slush's pool and elgius but not on s1.ghash.io:3333

not sure wtf happened.

Proper adressess
US
us1.ghash.io:3333

EU
nl1.ghash.io:3334

try use stratum+tcp://us1.ghash.io:3334

ghash.io just had some downtime right at that moment.

I'm not sure about stratum proxy, but at least with BFGMiner if you omit the stratum+tcp:// part connecting to ghash.io will take a very long time. Haven't seen any other pool with that kind of issue. Without stratum+tcp://, the miner will try to connect using HTTP at first, and on all other pools, that always fails immediately so it tries stratum next.

Code:

how do i determine what sdx and /path/to/image is in Ubuntu?

Just type df and you should see the sd card and known which /dev/sdx it is.
Why do you want to copy the bad card ?
Why not just download a fresh image and write it to a new sd card ?

i have a good card to copy from.

do you have a link to download a fresh image for v2.2 h boards, and v3 m boards?

There are links in OP

all of a sudden got a dead rig.

i can ssh in but don't get the normal log printout on login nor can i call up a stat.log. raspi has green, red, yellow lights as normal but 0 hashing. tried rebooting to no avail.

any suggestions?

Had same problem. In my case there was two burned boards. Remove all boards except one in each bus, try again. If it work add one board by one.
In my case two boards was burned.

that doesn't even work even with diff h boards in the first slot. still can ssh in but no stat.log. can still access BF GUI but 0 hashing.

does this imply a defective M board?

1 - start Chainminer manually sudo /opt/bitfury/start-miner-console.sh and check log.
2 - Try other SDcard and RasPi
3 - Check 1V8 and 3V3 on M-Board - You can measure 1V8 on coil L01 and 3V3 pin 1 Raspberry socked.

well there you go. bad sd card.

need to copy image over to bad card.

by running this:

Code:

dd if=/dev/sdx of=/path/to/image bs=1M

this is what lsblk returns:
