As requested I am releasing updated Windows 64-bit builds of cgminer.  Code retrieved from the git repo 2011-11-18

They come in sse2(x86_64) and amd10 flavors(phenomii).  Both builds have ADL and APP (for use with ADM cards). 

They are mostly statically linked (the one needed DLL is included - source available from pthreads link). 

Known issues: the time doesn't display, fails to run properly in cygwin. 

I have not been able to get a working dynamic build, but I'm still working on it. 

Please give any information you can about the builds especially if you can speak towards their integrity.

He's offering 64 bit builds, which every once in a while someone requests. Of course there is no point to them over the 32 bit builds I provide unless you're CPU mining.

Ah OK - just seemed a bit suspect for a noob to be posting executables Smiley
(and I did look for a reference post near all of his but couldn't find one)
But since there is a specific use - anyone losing money CPU mining - I guess that makes sense - though it does ADL/GPU and CPU ...

100% CPU Usage Bug for me under Linux with 4 x 5870 with Catalyst 11.11 fixed !
Yes. I can confirm that!

I have a request to be made into a future version:

When starting CGMiner with --auto-fan --auto-gpu it seems to spin the fans up to the threshold (85%) and then work down from there...sometimes going from 15% RPM -> 85% RPM instantly.  This may/can cause issues with certain fans on boards I would think.  Would it be possible that when starting CGMiner, it will start spinning fans up from current RPM/% to the max/desired ?  This would help because the fans don't need to spin up to that speed right away Smiley

No. I cannot. Everyone has their own interpretation of what is "correct behaviour". As per the FAQ in the readme, the defaults are the safest. Imagine you restarted something instantly and the GPU was already at max temperature.

That's fine then, I just can't see how spinning a fan from near to nothing to near max is healthy.  Too many of these and and you might end up like JL421.  I would then imagine that cgminer would scale up the fan speeds to compensate, but alas.

If it's a no, it's a no.  Would be nice though, even as an optional feature/method.

If you match your case you just said "Too many of these" then you would endanger the GPU badly since why would you be doing lots of restarts?
Most likely the GPU was already busy processing thus it is HOT thus the fan needs to be up and running ASAP.

If it's not hot, then why would you be restarting the miner over and again?

However, if 85% is bad, what figure isn't bad? It's a fan.
Are you seriously saying it can't normally be switched from 15% to 85% without expecting to damage it?

You can spin up a little GPU fan from 0 -100% instantly all day every day and never damage it.  Slowly spinning up a fan is only needed when you are dealing with 10hp electric motors connected to fan blades in HVAC units for large buildings, like at my work.

I dont see the problem either way. cgminer could check temperatures before setting fan speed, if its near or below target temperature, there is no need to set the fans to max. A card isnt going to overheat by running the fans at lower speed for one  second or however often cgminer polls temperatures.

Then again, I dont see the harm in it either. If you are worried about the fans spinning at 85% for a few seconds, you shouldnt have 85% as your upper limit for auto fan either. Set it to 65 or whatever, and set an overheat/shutdown temperature to make sure the fan doesnt need to spin faster than what you deem safe.

Just to quench your curiosity, it was freakfantom and he/she requested via PM. 

Also, you bring up a good point the next round I will include a version without ADL and APP.

Who would be willing to add an rpc interface to cgminer and have the code added to the next release? I would like to see this feature added so others can programatically access cgminer. I would be willing to pay of course, in btc.

I will add 30 BTC to any bounty started for such a project.  I would also award a bounty for a fork if it isn't feasible (due to different scope) to integrate into the main branch.  A fork might actually be the best solution as a lot of code related to output and display could be removed.  Hell all CPU mining code could likely be removed to in order to simplify the project.  

Honestly all I would want is a daemon that is started by config file, has no command line output (think bitcoind running in server mode) and responds to RPCs.

It should handle at a minimum the following RPC to satisfy the bounty:
* start/stop/restart GPU (on restart recheck config file for any changes)
* shutdown instance (stop all GPU, and end cgminer)
* report current monitors (a min of current temp/load/clock/hashing speed)
* report global output (a min of total shares, accepted shares, rejected shares, stale shares, etc)
* report individual card output (same but on per card basis)

I am not set in stone for these being the requirements just trying to get a starting place.  Obviously a lot more could be done by RPC (change clocks, intensity, etc) but to keep scope small I think we could start with the above and then once released look to expand the project via donations/bounties.  I have considered doing this myself but if I am being honest with myself I doubt I have the time so I am willing to pledge towards a bounty pool.

Well, seems like this idea might catch on.  Cheesy

DeathAndTaxes, thanks for offering up the bounty. I will add another 30 btc to see the work completed as you suggested.

Anyone else want to join in?

I started a new thread to keep RPC bounty project talk contained and create some dialog with potential developers.

https://bitcointalk.org/index.php?topic=52466

gigavps & tnkflx is you could indicate your pledges by posting in that thread I will update the first post to reflect it.

can you strip miner code from cgminer, auto-over/under/clocking and fan management looks useful for gaming
