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

That won't help if it's the first time you're running it...

If you have a previous working version, you can copy all the .bin files from there into the directory of the new version and it should work. It remains a mysterious windows only bug.

I just wanted to reiterate the importance of having backup pools.  cgminer makes failover super easy and I actually get more shares submitted with multiple pools.  When my Pool 0 doesn't provide work fast enough, cgminer is smart enough to send a few shares to Pool 1 and then go back to the primary when it gets work.

What would be the best way to setup solo-mining as a backup? This would be helpful in case of another large scale DDOS attack that takes a bunch of pools out.

cgminer just sees your solo mine as another pool.  So from cgminer perspective it is the same (except the "url" is an IP address usually 127.0.0.1).  You need to setup your bitcoind to accept RPC calls and provide it a RPC username/pass in bitcoind.conf.

Have you tried this in 3.0.7?  I know from previous posts of solo miners (who I assume don't mine to a pool since they complained about this) that it actually doesn't show rejects like a pool because it knows they aren't shares because it knows the real difficulty target.  I wouldn't be surprised if you can still just add it to the list, but I also wouldn't be surprised if you needed to set up a pool so the target difficulty would match and the shares would get accepted (similar to how you can't mine two different chains directly from CGMiner [not merged mining], although they have different hash targets difficulty notwithstanding).

I have solo mining setup as my last backup.

I start my bitcoin client with something like "bitcoin.exe -rpcuser=username -rpcpassword=password -server" from the bitcoin client directory.

Then I point CG Miner at "-o http://127.0.0.1:8332 -u username -p password" just like any other pool.

So I have the Bitcoin client and CG Miner running all the time.

You can add solo mining as a backup in the current version as well, it just won't show any shares because there's no such thing, only block solves.

How do we know for sure that it is actually working?  I'm still using 2.0.5 part of the time because it gives feedback that solo mining is working.

Faith....

Or debug mode if you're really concerned.

I thought you were going to say something like that

As for debug mode, that would have a serious performance hit wouldn't it?

I'm fairly confident in my configuration now so I guess it doesn't matter much now moving forward as I can always fire up an older version to test if I felt the need.

I was a little unnerved when I stopped my client running in server mode and CG Miner kept hashing at full speed.  I would have thought it would have detected the failure.

The CPU usage of cgminer is extremely low. Most of the CPU usage you see is the driver interacting with the GPU. Even in debug mode there would be no demonstrable performance hit. As for hashing, it will hash if there's something to hash and something to communicate with. It won't keep hashing randomly on any old shit just to pass the time. So if it was hashing, then it was still communicating with something, or the driver hung.

Hmm,  I may do some more testing on my config and see.  I'm sure I probably did something wrong or overlooked something.

Anyway I have *faith* that it's working correctly now.

Bump.

Is cgminer better than guiminer and barelyclocked?

Does it support voltage changes on a lot of cards? Do they have to be of the same model?
Im using guiminer + barelyclocked ATM, but with BC I cannot change voltage or memory clocks on my non-ref VTX3D HD 6850 (only trixx does that well but I can only increase it), on my Sapphire non-ref HD 5850s I can only OC GPU core to 900MHz (memory and voltage changing works fine).

Ok, someone said I might get 7Mhash/s more, anyone got answers to my other questions?

There's options for engine/memory/voltage, but I ran AMDOverdriveCtrl before I fired up cgminer to modify the ranges, so I can't say if it will modify them outside the normal scope.  I think it might be easier for you to build/download cgminer, pause your current miner for a minute and try

What messages does -quiet include?

Rejected shares?
Pool unavailable?
Not providing work fast enough?
Hardware failure?

Essentially I would like an output which has everything except accepted shares to make the logs more compact.  Is that possible?

I think -quiet also removes rejected share and "not fast enough" notifications so it is kinda too quiet.

Also what is the syntax for using -text-only and -quiet flags in configuration file.  I can get them working from commandline but trying

Code:

"quiet",
"text-only"

in config file results in parse error.  The example config file has no "valueless" configuration items so not sure what the syntax is.

I thought maybe I need a "dummy value" for the variable : value format so I tried

Code:

"quiet" : "0",
"text-only" : "0"

but I got a different parse error (invalid value for text-only).  

[Pontius]

Code:

"quiet" : true

Works for me.

[DeathAndTaxes]

"quiet" : true

DOH.   

Thx.

Avast suddenly started throwing false positives on cgminer recently.  I don't know if it was included in a recent defs update or what.  I have submitted a false positive report to Avast for review.  You're welcome!

Can the MSI Afterburner and ATI CCC be uninstalled from and Windoze XP mining systems since I'm using CG Miner for the clocking?
Thanks,

Yes.  I find the system a little more stable without CC.  Only other utility I use is GPU-Z because it has some nice monitoring features like checking VRM temps.

I find with GPUz running my GPU load drops to 70%
that with 3 5970's on one machine.
