OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.10.0

[tadzio]

Im running 3x Bi*Furry on powered USB HUB - power is sufficient.
Randomly (after 10m - 4h) I get:

Code:

BXF 2 BXFWork usb write err:(-7) LIBUSB_ERROR_TIMEOUT

and miner crushes (WIN 7).
Any idea?

That is a sign of hardware instability, not software. If you're 100% sure you have enough power (and most people don't have as much as they think they have) then the next thing to do is actively cool them better.

EDIT: Do you mean "crashes" when you say "crushes"? In that case you may be able to help by running a debug version and following the instructions in here:

I have two Antminer S2s.  Both misbehave the same way with p2pool.  Within minutes of pointing them at p2pool, my hashrate drops to 930gh/s or lower. 

It shows this way on p2pool, on the S2 LCD, and on the S2 web UI.

It stays this way, or gets worse, as time goes by.  I've run against p2pool for days this way trying different things, and the result is always the same.  Yet running on a conventional pool (like Eligius), things run fine immediately and ongoing.

I've tried adjusting my pseudo share size.

I've tried running on a local node, my public node (other side of the country), and at least one other public p2pool node that was close to me.

Since S2s use cgminer, I was hoping a dev might be able to shed some light on this for me.

BTW, my S1s work fine with p2pool.  At 1/5 the hashrate, but they do work fine.


I apologize if this has been mentioned already.  I stopped following this thread a while ago.

Thanks.

You are running bitmain's S2 driver. Don't do that on p2pool. Also don't do that with bitmain's S1 driver.

Bitmain does some terrible things in their driver including ... discarding stale work in the driver before passing it to the work validation code.
This means on p2pool that if you find a stale block that is still a valid network block, it will be discarded. Oh well.

Use my driver for S1 if you don't want to throw such valid blocks away on p2pool.

My S2 driver is still in development - I'm still trying to work out why the device thinks it's a good idea to have >8000 work items queued in it - more than 30s of work - and to work out how to reduce that without letting it get idle - so I'm still waiting on source code from bitmain.

My blackarrow minion RPi driver is able to handle > 2TH/s of work at 1diff verifying every share returned at 1diff.
The S2 driver, on a faster BBB, should be able to handle 1TH/s of work at 1diff also. It doesn't. So I need to work out how to fix that - but I need the SPI kernel driver code bitmain wrote, for me to work that out.

Hi, I noticed a strange behaviour in my mining equipment:
Sometimes out of a sudden I receive BTB: Idled 1 miners for no reason at all. No new block detected by stratum.

http://imageshack.com/a/img841/5870/h19c.png

I am running BitBurner stacks with --avalon-auto on GHash.io

What are the reasons for "idling" miners at such low temperatures and no block detected? Is something wrong with the equipment?
However utility remains pretty high at 22,24 shares/min.

Thanks in advance.

Thanks!  I also get duplicates on p2pool when using my Ants.  I think I only saw that with S2s, though.

Might mean your network connection had a hiccup.
Otherwise, ignore it.
I found that message in my cgminer logs 39,007 times with my one BTB board from 12-Sep-2013 until I permanently switched it off on 16-Apr-2014

Hmm this is weird...
I restarted CGMiner, the problem no longer shows up and hashrate has increased. Could be a memory leak? I'm taking a look.

Hey Kano - did Bitmain get back to you yet my man?

My poor S2's are crying out to be set free.........

Peace.

The mandatory solo mining parameter "btc-address" almost sneaked by me——don't want to be mining for someone else. A reminder to everyone to actually read the readme.

You can't mine for someone else. It simply wont mine without an address. There was only one older version that would mine somewhere else if you didn't put an address in and it was removed quickly because of the complaints.
