Added info about the CGMiner ... for BitFury

- CGMiner for BitFury

can anyone interpret what this means?


I saw my hashrate drop slightly, I am hashing on 3 workers (two different pools). I know it reads "Queue length   Getworks  Nonces found   Nonces submitted   Server". Does btcguild have so little nonces comapred to eligius because difficulty setting is much higher? (it was 64 but i only hashed with ~25gh, oops  ). It seems I have problems with spi/msi errors? Is this bad? Or can I ignore that, as it is only a tiny percentage?
What if the queue length switches between >0 and <100? Is this bad? I sometimes see the hashrate on the pool (eligius) drop drastically. This seems not to happen on btcguild, but I'm no fan of hashing on the biggest pool out there. I want to support smaller pools. Please enlighten me you guys! 

+1 thanx a lot ...

sadly it had those before
It has one duff chip thats forced back online at 48 that give the odd miso

ill keep an eye on it, I avg about 5-10 miso errors over the 2 boards without the mod over 24hrs

Nice but it seems that the mod introduced Miso errors that could contaminate other boards (in case more are in the same m-board).

r02 @ 1.199k with 6b pencil

I don't know how serious the danger is. The voltage regulator has a current and temperature limit, so it should protect itself. From what I've seen, it just turns itself off when it's not happy anymore. The card will stop mining, but a quick power cycle will fix it. Of course, if this happens when you're not watching, you could lose a lot of hashes, so I wouldn't get it too close.

Of course, increased heat will decrease lifetime of the chips, but how important is that given the increasing difficulty ? A few months at 120% rated capacity may return more than a few years at 100%.

yep, some reported that they did the trick up to 5-6 times ... until they got the cards up to 28GH ^^ ... i would suggest having the chips working at 2.0 - 2.1 GH is a good number ... ^^ im unsure if going higher then ... 2.2 per chip ... is viable ... but maybee some of the experts can comment ...

what is the danger of the pencil trick ....? what if it gets under 1.1K Ohm the r02f ? ... anyone that can do some light in the dark?

Ive just used the pencil trick on my boards, for ref a 6b pencil allows for finer tuning of the value on the r02 resistor.
Ive gained about 5ghs/board

I still get some chips turning off and drop in hashrate along with it. Stopping and restarting temporarily fixes the problem. I hand tuned chip speeds and turned off autotune. Seems like a software problem. If the user can restart non-producing chips by clicking stop and restart, mining software should be able to do it automatically, or even avoid the problem alltogether.

It's a US version.1, so I cant move it to any other slots.

Did you put the boards in slots A1 and B1 ?

Try using another slot.

Doesn't look like it wants to go further.

Try setting '25 aIfDSo 0' then the chips 25-32 will hash too.

Could somebody give me a hand figuring this out?
I disabled #25 (I think), but how do I go about bypassing it? I am a n00b at this, so....

Yours still running at 20 GH/s in  bus B and C?

Can you post your /run/shm/.stat.log file?

Thanks. I was able to take a snapshot of the stratum log and this is a sequence that repeats all the time. (None of the lines below seems to be displayed more often than the others, pretty much even distribution)

Anything that seems suspicious/wrong??

Looks to me like too many warnings but would love to learn what each of those line means...

both my H cards have soldering errors ...

I pencil modded 3 fury boards and gained quite some speed.

Blue line is Avalon overclocked @350 = 82GH
Green is Bitfury starterkit with 3 boards ...
