Every time I go looking for answers I see no end of posts saying you must put these lines in your batch file:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
For Win7 users I think this is nonsense. I deleted them from my batch file and from Windows Environmental Variables since they stay there forever until deleted. If I open Windows Resource Monitor I use significantly less CPU with a multi-core CPU than if I set GPU_USE_SYNC_OBJECTS 1, which as best as I can tell forces the use of a single core. Aren't CPUs designed to direct traffic? Why not let them do their job? Most of my miners use a low power consumption AMD Sempron 145 CPU which only has one core anyway. Why even tell windows to use only one core when there is only one core?
As for GPU_MAX_ALLOC_PERCENT 100 it seems to do nothing. Trying running for 24 hours with it set to 100, 40 and then deleting it. I don't see any difference.
Thank you very much for your advice, I'll try excluding --auto-gpu (although I think it's a long shot  ). I have set those two user variables in windows 8, but like you said, I'm not sure they are doing much. Also what I didn't mention yet is my OS Spec: Windows 8 64-Bit Catalyst Drivers 13.1 Anything wrong with that? Hi, Your main problem is twofold: intensity is way too high for 7xxx GPUs, and thread concurrency is too high. I have 32-bit and 64-bit Windows 7 PCs and have never tried Win8. For 7XXXs I'd recommend uninstalling Catalyst 13.1. Running AMDs cleanup utility. Running Guru3D Driver Sweeper. Then install Catalyst 13.4. I never tried 13.1 and it may work just fine. But, 7XXXs run great with the latest drivers so I just stay current. Just my two cents worth. |

--scrypt --api-listen --api-network --api-port 4028 -I 20,20 -g 1 --thread-concurrency 22400 --lookup-gap 2 --temp-target 75,75 --temp-overheat 80,80 --temp-cutoff 85,85 --gpu-memclock 1250,1250 --gpu-engine 300-1100,300-1100 --auto-fan --auto-gpu
Another thing, I see you're putting all this in a command line. Better to minimize your batch file and edit your conf file. Here's my batch: timeout /t 20
cgminer.exe -c MultiPool_Miner_Aurum.conf
pause
exitI make a shortcut and put it in my Startup folder. I set my BIOS so that if the power goes out it restarts. The timeout is to allow my miner to discover a network connection and finish loading stuff before launching cgminer. The pause gives me a chance to read the run summary before closing the cmd window. |

Hi All,
I'm currently running CGMiner on 2 7950's (NO CROSSFIRE), with the following settings:
--scrypt --api-listen --api-network --api-port 4028 -I 20,20 -g 1 --thread-concurrency 22400 --lookup-gap 2 --temp-target 75,75 --temp-overheat 80,80 --temp-cutoff 85,85 --gpu-memclock 1250,1250 --gpu-engine 300-1100,300-1100 --auto-fan --auto-gpu
I'm getting extremely frustrated with cgminer results as they make no sense to me, for example:
GPU: 1, Rate: 310kh/s, Temp: 75 °C, Fan Percent: 37%, GPU Clock: 1100, Mem Clock: 1250, Intensity 20, HW Errors: 0
GPU: 2, Rate: 660kh/s, Temp: 76 °C, Fan Percent: 100%, GPU Clock: 500, Mem Clock: 1250, Intensity 20, HW Errors: 0
How the hell is it possible that GPU 2 has a higher hashrate with the lowest GPU Clock?
Why is my Fan Percent on GPU 2 100%?
Why isn't my Fan Percent not going up on GPU 1 as temps are about equal?
Why isn't my GPU Clock of GPU 1 throttling down?
This is driving me nuts, I have went through the documentation and numerous forum posts but no help.
Please, Anyone, Help me out!
Cheers,
I don't know the answer to your questions but I never had a lick of luck with auto-gpu. All my 7970s run great on this configuration: "scrypt" : true, "intensity" : "13,13", "vectors" : "1", "worksize" : "256", "lookup-gap" : "2", "thread-concurrency" : "10240,10240", "shaders" : "2048,2048", "gpu-engine" : "1050,1050", "gpu-fan" : "0-85", "gpu-memclock" : "1650,1650", "gpu-vddc" : "0,0", "temp-cutoff" : "95", "temp-overheat" : "88", "temp-target" : "75", "temp-hysteresis" : "9", "api-port" : "4028", "auto-fan" : true, "expiry" : "120", "scan-time" : "111", "queue" : "1", "failover-only" : true, "gpu-dyninterval" : "77", "gpu-threads" : "1", "hotplug" : "0", "log" : "5", "shares" : "0", "kernel-path" : "/usr/local/bin" |

I have finally gotten some mining going after a lot of fooling around with drivers. I'm running xp 32 bit, Radeon 6670s, sdk 2.5 and catalyst 11.7. I have two machines that I believe are almost identical. However one I have running fine at 94 khash/sec.
The big problem is the other machine that seems to be getting a lot of hardware errors (hw). Anyone hav any ideas what can cause this? I'm just running it standard with I 15 and have tried fooling around with the core
Clock and memory. Thanks for help I just don't understand hat can cause hw errors.
Btw this is scrypt mining, coincidentally at flounds pool multipool.in. An yes this stratum issue is really annoying, hits both my miners to cause often disconnects which I can only assume are slowing my hashing. I don't have any 6xxxs but my 5970s mine scrypt using Catalyst 12.8 and 7970s using the latest Catalyst 13.4. Don't install SDK separately, just let Catalyst install it. Are you using CGMiner 3.3.1? Sometimes when a miner is headless the card in slot 1 runs very slow. If I plug in a monitor or a dummy load it ramps up to full speed even if I unplug monitor later. If you go back a few pages ckolivas was discussing the stratum disconnect issue says there's a fix but it hasn't come out in a release yet. He described a way to pull the fix code out of the git library. |

I will be moving the EU pools to a different server tonight to address some of the reliability issues. For now I am increasing the share difficulty to 64 to help lower the load a bit.
Was the difficulty increased on all coins, even on the US server? It is stated on the website newsbar that it was increased on all servers. You're right, look at that. I used to keep an eye on the newsbar but Flound had stopped updating it for a while. With such a high difficulty, it's pretty much useless to mine using a CPU or slow GPU. Hopefully user selectable difficulty per worker will be available soon. If I could set my own difficulty how would I decide what value to use? I'll have a chart up on the help page to help you decide. Thanks. Let me ask another way. If I have a fast GPU, e.g. 5970s and 7970s, am I hurt by having the difficulty too low? |

Is there anyway I can include a comment in my cgminer.conf file?
I tried /* comment */ but it crashes.
No. You can put unused objects: "janssonsux" : "yes it does" However, they will be lost if you write the settings back to the file from cgminer. I tried a few variations but they all failed, e.g. "url" : "stratum+tcp://pool1.us.multipool.in:3348" : " MegaCoin (MEC) ", cgminer.exe: -c: JSON decode of file 'MultiPool_Miner_Aurum.conf' failed '}' expected near ':' No, I mean you can put unused items in there: "url" : " http://sendyourcoinstome.cam:3334", "url_666" : "damn I hate json", You can't break the json rules. Oh, json rules, I thought you meant Jason sucks  Works great, thanks. |

Is TRC really 7x or did a decimal point slip?
Of last 15 blocks 13 are orphans. Did we get forked?

I concur!  I re-challenge all of you doing so well on the Multipool, to raise your Donation level to 5% for the rest of July. Show some appreciation beyond taking today. Be well. T. How about 4%? Still gotta pay my electric bill The MEC stats chart show that MultiPort is a force to be reckoned with. Being listed on MP should be like getting The CryptoCurrency Seal of Approval. |

I woke up from my nap and MEC was gone. I must've only dreamed that I'd been mining it all night 'n day at 3x.
Wait, no, there's tons of coins in my wallet.
Where did MEC go?
Ummmm, it's still there bro you sure it was a nap? Nope, taint there: https://www.multipool.us/index.phpI wish it was a drug-induced stupor, but... Why are you using multipool.us? Nobody is supposed to know about that domain, it's not ready yet  I don't know, cuz I live in the us of a maybe? I type "mu" and google just sends me there. Hmm, I knew something looked funny, I usually go to MultiPool.in |

Adding CAP tonight or tomorrow.
This is the last scrypt coin I will be adding until after PPC and the SHA-256 multiport are set up.
"... PPC and the SHA-256 multiport are set up." I love you man |

I tried running cgminer on windows 8 for the first time today and I didn't have any luck. It works fine for btc but I can't get scrypt to work. It stopped responding on windows. Is there a known issue with it?
What drivers/SDK? The newer ones don't work. I'm using Windows 7 and all the latest ATI drivers, SPP and SDK work fine for 7970s. But, I cannot mine scrypt on 5970s to save my life. The documentation confuses me. SCRYPT-README.txt says, " The choice of driver version for your GPU is critical, as some are known to
break scrypt mining entirely while others give poor hashrates. As for the OpenCL SDK installed, for AMD it must be version 2.6 or later." But the GPU-README.txt says, " The best version for Radeon 5xxx and 6xxx is v2.5, while 7xxx cards need v2.6 or later, 2.7 seems the best." (2.8.1 works fine with my 7970s.) So I installed the latest drivers from Catalyst 13.4, the latest SDK v5.0 and SPP v2.5. I compiled CGMiner 3.3.1 and 5970s cannot mine scrypt. I noticed during compiling that "--enable scrypt" is an unrecognized option. I also tried: CFLAGS="-O2 -msse2" --disable-option-checking ./configure --enable-scrypt but that did not work either. Any help would be greatly appreciated. TIA. 1) Do not use 13.4 with Scrypt. Actually even 13.1 won't work. Uninstall the drivers/SDK on your computer, and install 12.8 drivers (with included SDK). 2) You're building from source on Windows? Have you tried running the available binaries to see if that fixes it? It's just like magic!!! Thank you thank you thank you thank you thank you thank you thank you thank you... |

Why are you compiling cgminer yourself when there is an already compiled Windows version available? All you would need to do is install your catalyst drivers, set your parameters, and go. Yes, I'll try that first. But, it didn't work before when I tried it with Catalyst 12.6. I sure hope 12.8 is the answer. |
