Don't you need a level shifter on the comm lines?

My FrankenFury

Got my hands on one of H board no M board so way not create your own FrankenFury

If anyone want to take a tracking of his Bitfury based on performance data of each card, here you find a macro for Excel which track all JSON-data each 5min. It delivers you some results as table and chart. You can analyze as you want, e.g. by card, bus, slot, SPIerr or MISOerr.
Just open in excel, enter IPadress and click start.

okay, i measured, it was 0.3V or 0V, what i can do next?



problem card,A1, not detected

The bitfury chip is really impressive.
During my tests it was happilystoically endured running at 1.24V for half an hour at air cooling with about 80-85C, but after accounting the HW errors those 3.5Gh where actually just 3.1Gh with ~5W per chip ... not worth it, while it can run at below 0.8W (~0.75-0.76W) per Gh at it's optimal 2.3Gh.
Unfortunately each chip is a bit different and requires a bit different voltage for it's optimal speed.

change the first to either autotune 'A' and/or change the value to 53. it shouldnt be 240 and is probably caused by a mis-match the last time the file was modified (mine showed 545 once but worked once returned to a usable number). check your spacing

turn chip 2 on. use autotune or start at 53.

tune chips 5 and 12 to either 53 or autotune. 50 is too low and may be your issue.

finally, im surprised you could get 0.95v even with liquid cooling - pretty impressive. scale back to 0.90-0.92v as its a safer level and watch your autotune. ideally your chips should be 53-55 (most of mine run 54 when my system is stable near its cooling capacity)

A better test would be to power the card and measure voltage at the top of the Pulse inductor. If you get ~0.75v there (or whatever it's adjusted to), the power circuit (including that capacitor) is probably fine. I only say "probably" because I just fixed a board that was missing a cap on the back side. Before replacing that tiny back-side cap, the voltage at the Pulse top was correct, but the card wouldn't hash stably.

yeah, i know it... But i measured other card and third, capacitor was like 0.7M ohm...?

heatsinks should be on the other side of the board. Those components you circled should be 0ohm so that's not the problem.

Can you post log from miner page ?

I have problem, one my h-card doesn't work.

Its not hot, no hashing, 20W, it worked 12h ago very well (28Gh/s), it seems m-board not even get information from h-board.
I tried change new ssd card also.

What is wronng, how i can fix that problem?

Are you still using the old version of chainminer that shipped with the v1 M-boards? It either doesn't change the clocks, or it doesn't display it right. I upgraded to the latest version on github, and now autotune actually works (except for half-dead chips). But make sure to edit the version number before compiling if you have a v1 M-board!

The column after the [4:x] shows how many of the 756 cores have not produced good results. It looks like chips 5 and 12 are half (or more) dead, so you'll need to leave autotune off and just accept that the noncerate on those will be less than half their hashrate. You can try different speeds to see what produces the best noncerate. You'll probably want to clock them as high as the rest, and just expect 50%+ error rate. Chainminer autotune can't handle chips with alot of dead cores and assumes they need to be downclocked or shut off. After running for long enough to get most of the bad-core counts near 0, look at /tmp/.core.log and see what 5 and 12 look like. It'll probably show that one side or the other is dead. Here's one of my half-dead chips:

But why the other chips with capital "A" is not changed their frequency from 55? Day after day frequency is not changing...

A lowercase 'a' starting the string means you have turned off autotune for that chips and manually set the values...

Another question:
What means if one chip shows aifdso 240?
Like the first one


And it seems that autotune is not working, on the screenshot I manually worked with 2,5,12 chips. The first one is setted up to AIfDSo 55 but automatically falls down to aifdso 240. The second chip was turned off by me because of very low hashrate (200Mhs).
Can you tell something about the first chip? And maybe you know what should I do for 2,5,12 chips to increase their hashrate?
Thank you!

ps: overclocking to 0.95v and oil cooling change nothing...

It may trigger the TVS diode on your raspberryPi and destroy it. I would suggest turning off the PSU instead of yanking out PCIE power cables.

10A 250V switch should do fine. Low voltage DC is much easier on the switch.

I've used a 10A 250V switch on my electric kick scooter for years. Peak current >100A and it's still working fine after probably 2000 on/off cycles.

1. cp /run/shm/.stat.log /opt/bitfury/best.cnf
2. If /run/shm/.stat.log doesn't exist, let the miner run for at least 5 minutes and it should be there.
