OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

[-ck]

Hi there. I am here to report what looks to be a bug in cgminer. This bug manifests itself if you run cgminer pointed at the stratum port of the bfgminer proxy. This has been reported by numerous users, usually trying to point their KnC miner at the bfgminer proxy:

I've been drowning in moving houses and having no stable internet. I'll look into this when time permits, thanks.

anyway to use cgminer with blades yet?    

There is no way to have a miner mine on a blade.
Blades have their own crappy internal last generation getwork miner.
All you can use is a getwork proxy or a getwork pool.

I appreciate that Con. Kano's only response was to question my personal motivations for posting the bug. Which is awesome...

1. I'm trying to get an MSI Z87-G45 mb running Win8.1 to mine with 7 cards but it only mines with 5.  Windows Device Manager recognizes all 7 cards.  Any ideas on how I can get cards 6 and 7 to mine  

Use Linux, Windows doesn't support 7 GPUs.

Funny then, why are there several motherboards made expressly to run 7 graphics cards???  Why does Windows Device recognize all 7 cards.

I believe the bug is in cgMiner 3.7.2

Maybe because not everyone uses Windows?

Could just as easily be a problem with the AMD drivers.  They aren't known for their stellar performance and proper behavior in all circumstances.

Regardless scrypt mining is no longer supported in cgminer.

This guy claims that the 11.12 or 12.1 driver can support up to 8 cards on Win7 or Win8.  I haven't tried it, so I have no idea if this is accurate or not:

Can anyone confirm that it is the WU that pays, and that I should choose the pool which give me the highest WU? I have noted some realtivly big difference from pool to pool.

The WU is what pays, but pools running stratum protocol have precisely ZERO effect on your WU. When your hardware remains the same, any change you see in WU is local luck and nothing to do with the pool.

Well, since only about 1/3 of the world has internet access, I'd be surprised if a vast majority of the world actually uses windows - since I'm pretty sure that it would be incorrect to even say that a vast majority of the world even has a computer.

I knew some grammer-nazi would whine about my saying people instead of PC-users 

I contacted MSI tech support and apparently it's the MB to blame. They sell the Z87-G45 saying it can run multiple video cards. It has three 16x PCIe slots and four 1x PCIe slots. One of the "PCIe" slots is really a 32-bit PCI in the guise of a 1x connector. I'm returning it for a refund as being SNAD.

Has anybody tried the new ASRock BitCoin MB

The best way to get those to run 7 cards is

 Press Down, R, Up, L, Y, B on controller two at the scrypt selection screen

Sorry if this has been discussed earlier in this topic, but it's almost 700 pages long and I couldn't find anything while searching.

My question is regarding the --no-submit-stale option. Forgive my ignorance, but why would you ever want to submit a stale?

It depends on the pool.  On some pools, for example p2pool, a stale share may still be a valid block and so if you don't submit stales, you risk missing out on BTC.  Historically, there have also been pools that paid for stale shares and so you always wanted to submit them.  I don't know that any current pools still do that though.

Ok, thanks. That clears it up a bit. I'm not sure how a stale share can be a valid block though. If I'm not mistaken, a stale share is the result of an "old job" from the pool. In other word, a job that was submitted after someone else had already solved the block.

Whatever you want - chase your tail.  Windows doesn't support 7 GPUs, period.  Whatever you think doesn't change that fact.

Motherboards may have 7 PCI-E slots, doesn't mean they're made to run 7 GPUs.  Other things use PCI-E - RAID cards, sound cards, NICs...

So, yeah, use Linux.
