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

[tiberiandusk]

I'm not getting any better performance, just higher temps and snarky support. Back to phoenix I go, where my card runs full out without melting.

Thanks for the tool ckolivas... it's beautifully functional and keeps my temps exactly where I put them .

[Graet]

works as designed for me

I guess if a person cannot use the software he is better using something he can...

[xzion]

being able to keep my rigs quieter with auto temperature management is a godsend, and it mines faster than phoenix. what was the problem again?

[P4man]

All that extra heat is coming from somewhere. Since I believe in the laws of physics I would have to say it is using more electricity.

Not necessarily. Temperature sensors are in particular places on the GPU. The heat is relatively local.  Moreover, the default sensor is IOdisp, which is not the same as the sensor in shaders and the difference can be substantial (+-10C easily). THe only way to know for sure if one miner uses more electricity than another is by measuring power consumption. Temperature is a very poor proxy for that.

You do understand the temp rise is simply an indication that cgminer was working the card slightly harder.  Nothing more.

I mean if you reduced the chip's clock by 2% to 3% then temps would fall would you consider that superior also?
Likewise if every time a round was finished cgminer idled for 2% to 3% of the round time temps (and hashing performance) would fall would that be a superior product?

cgminer is simply a more efficient miner.  It drives a card as hard as it is possible w/ very little wasted clock cycles.  If you want lower performance you can always lower clocks or intensity but it seems stupid to consider the less efficient miner to be superior because it is less efficient.

Has any successfully used gpu-vddc on Radeon 5970 cards? The GPU results when looking at details are providing the correct results at 1.050 but if I change the voltage to something else it still reports the stock voltage. I'm running 8 GPUs (4x5970) so I am using Linux due to stability issues in Windows so I cannot use MSI Afterburner or similar Windows tools.

I just tried to change the voltage, but when I add the voltage line to the conf file, the program reports an error parsing json conf file.
"gpu-vddc" : "1.05",

I'm not using a json config so I'm not sure what that may be. On the latest version it recognizes the config option gpu-vddc but doesn't seem to apply it to my 5970s.

I *think* it also depends on the amd drivers you use. I could be completely wrong here, but I think it only works on older ones (like 11.6 that ships with linuxcoin). If you are using a recent version of ubuntu, you would have newer drivers by default. On ubuntu 11.10 I was unable to clock over 775 MHz, no such issues on linuxcoin.

[jjiimm_64]

But yeah - state exactly what you want with those 2 commands and once the CPU changes happen I'll put those 2 on first priority (for 5 BTC

I would like to add V to the list.  the more i read about undervolting, the more I want to try it.  especially with summer approaching.
Also, since reconfiguring a bunch of rigs will be easy to do from this interface, would be nice to be able to write the config to a file.


Kano,  I am willing to up the anti to get this stuff in....  10btc? anyone else willing to contribute?



1. ability to switch pools (i think setting a pools priority to 0 would work?)
2.  setting the following, for gpus's:

• "intensity" : "newValue",
• "gpu-engine" : "newValue",
• "gpu-vddc" : "newValue",
• "gpu-memclock" : "newValue",
• "gpu-fan":      "newValue",  ex(50-85)

3. ability to write current config to text file:   {command writeConfig,  param filename)

If you are using a recent version of ubuntu, you would have newer drivers by default. On ubuntu 11.10 I was unable to clock over 775 MHz, no such issues on linuxcoin.

The reason this happens is because there are specific hardwired voltages. I.e My card only accepts increments from 1.087 to 1.075, if I wanted to change it to say 1.078 it won't apply it. There are specific voltages that must applied, not such that you want to apply.

Hi.

Is there any way to send minimized cgminer msdos window, to SYSTEM TRAY??'

I have windows vista, i tried softwware like tray it! and it does not work

Thanks

[miscreanity]

I haven't switched up for quite some time: still running Ubuntu 11.04 with Cat 11.6 and SDK 2.4 with no problems for 69xx cards. There doesn't seem to be any real consensus on improvements in software platforms, although SDK 2.6 now appears to be the bane of mining.

Is there any definitive improvement with SDK 2.5 over v2.4, or any Catalyst driver version greater than 11.6?

Also, does anyone else use Arch for mining?

Firstly, there is no MS-Dos in Windows anymore. The correct term is "command line interpreter".

Your best bet might be going with Sysinternals' Microsoft's Desktops⁽¹⁾ app.
Create a second virtual desktop and move all those obnoxious text-mode windows to it, freeing your main desktop and taskbar.
The Desktops app lives only as an icon in the system tray.

With a little work you can set up a few separate, task-oriented desktops, like main desktop, bitcoin-mining desktop, porn desktop, and donating-to-cgminer-dev desktop.

I have Vista and TrayIt! indeed does work. You need to run cgminer, and while it is running, open TrayIt! Select to place cgminer to system tray, and put TrayIt to your startup folder. Should work.

On the BTCGuild thread we are talking about the efficiency of CGMiner for different users

I have 9 miners, all between 200 & 350 MHash, and on each and everyone of them the efficiency is between 10% & 20%

This is on 100K+ Accepted shares per miner, so should be statistically valid

I am not complaining or anything since my stales are on avg below 0.4%, just wondering if someone can explain the reasons why the efficiency is so different for different users

Why do you have 9 miners of 200 to 350 MH ea?  Do you have 9 rigs w/ 1 GPU each?

Low efficiency simply means you are requesting more work then you complete.  In case of 10% you are requesting 10 work units and only completing one.

[jake262144]

Dutch, what are those miners?
350 MHash is what a signle half-decent GPU achieves.
Are you using only very low-end GPUs?

What queue size and thread count per GPU are you using?

Yes unfortunately I do, I have 9 rigs, 2 with 2 GPU's and the rest with only 1.

I know what efficiency means, was just wondering why it is so different for different people.
I have no idea what influences efficiency

Using mainly 5800's 2 6950's

I am using default settings, no overclocking, intensity 8

I am not worried about the Performance, was just wondering about the low efficiency

I love Arch...mining with cgminer works great.

Well regarding over or undervolting cards
There is not really a easy answer, it all depends on how the card its bios is made.
I found my xfx and sapphire vapor-x cards not allow any underclock or overclocks besides the 3 steps programmed into the bios for the different power states programmed in the card
I had before some 5850 cards from asus who actually responded well to any overclock tool and settings where i could put in any value i liked, even which where much higher then factory allowed, so even though i set afterburner to allow voltage changes they simply refuse todo so

But the sapphire/xfx are not responding at all to any of the tools available (trixx, afterburner, adams tray tools) even the amd overclock tool crashes with the message no cards present. So i am stuck to be able to change only mhz on mem and core and thats it.

I have not read any people being able to flash these cards succesfull with asus top bios version so i kinda not dare todo so either.
Although i am sure these very well build cards could do much more with some slight overvolting
