There is no source config. It's been heavily customized by chrooting the filesystem and tweaking. 

Hi,

Is it possible to get hold of the source config for compiling the Linuxcoin liveCD there are a few things a would like to customize for myself.

So far LinuxCoin is the only distro that I have managed to get a Dual 6990 video cards working sucessfully, and I am interested to see what is different to say a install of Debian Wheezy or Ubuntu 11.04, for which I cannot not get dual 6900 video cards working.

Try this out



I don't think the clocks will make -+30MHs difference Those 5830's need to be whipped

Did you try mem at 305/310 etc?
Could be your mem clock is holding back the GPU performance.

320-335 seems to be the sweet spot for my 5870s, you need to find yours.

This is my startup routine:

To Start Mining:

Launch a Root Terminal

# cd /opt/miners/phoenix

# python phoenix.py -u http://USERNAME_miner0:[email protected]:8332/ -k phatk VECTORS BFI_INT AGGRESSION=9 WORKSIZE=128 DEVICE=0 FASTLOOP=false

Without closing Root Terminal #1, Launch Root Terminal #2

# cd opt/miners/phoenix

# python phoenix.py -u http://USERNAME_miner1:[email protected]:8332/ -k phatk VECTORS BFI_INT AGGRESSION=11 WORKSIZE=128 DEVICE=1 FASTLOOP=false


Using ATI OverDrive Control:


$ sudo -s

# aticonfig --od-enable

# aticonfig --odgc --adapter=0,1

# aticonfig --adapter=0,1 --odsc=900,300

# aticonfig --odcc --adaptor=0,1

# sleep 5 ; aticonfig --odgc --adpater=0,1

Do this twice, once for adapter=0 and once for adapter=1 if the arguement "0,1" or "all" doesn't work.


Set Fan Speeds:

GUI for device=0 you open by clicking the icon, GUI for device=1 you open by typing into a root terminal:

# AMDOverdriveCtrl -i=3

A new GUI will open for the 2nd GPU. Try loading the saved profiles into each GUI instance, otherwise manually adjust fanspeed.


I've noticed that if I set AGGRESSION on Adpater=0 to more than Adapter=1, Adapter=1 will slow radically and Usage will drop to ~30%, thus the settings above.

I'm sure we can help you squeeze a lot more out of your cards ! I can squeeze about 313MHs out of my 5830's what miner you using and whats your clock setup etc ?

PS: Working on the website and going to try and get a wiki etc online

You are definitely not useless, Folax! Thanks!

Adapter0
279.6 Mh/s, Usage=98%, Fanspeed=80%, Temp=67.00C

Adapter1
279.5 Mh/s, Usage=99%, Fanspeed=70%, Temp=59.50C

The side of the case is open with a 12" personal fan on Low, 6" away blowing directly on the GPUs.

Very pleased.

NOW- I need to move on to remoting this machine as a headless miner.

1. GUI for device=0 you open by clicking the icon, GUI for device=1 you open by typing in root terminal:
It will list your GPU's, I guess GPU0 is active, GPU1 and GPU2 inactive, GPU3 is active, this means GPU3 is the 2nd card, the one you want to run a new instance of AMDOverdriveCtrl for, so now you do:

A new GUI will open for the 2nd GPU.

2. I keep the GUI's open, the fans stay up to speed that way and it's handy to monitor temps.

Couple of questions about AMDOverdriveCtrl V1.2.1. I have two HD 5830s running

1. How do I change between the two 5830 cards? Seems like it only shows Device0.

2. Would the GUI need to remain open after loading saved profiles? Seems to be YES!

ATIconfig CLI Question:

1. What is CLI command to set fan speed at 80% for both Device=0 and Device=1?

For the fan setting to be saved in the profile, you have to click the set button in the GUI. Otherwise the setting active will be the one saved.

What I do is create the file with the GUI and then edit the profile text file manually and dont use the GUI anymore.

Btw, I found that the fan controlled by temperature (the graph thingy) only worked well with the GUI opened. You can save it to the profile, and load it, but it wont behave properly unless the GUI is opened. I dont care because I have my fans at fixed 90%, but others might. I opened a bug at the AMDOverdriveCtrl bugtrack but last time I checked there was no answer.

I understand people like to have things automated so they can reboot the machine and have all go by itself, but I fail to understand why you want to reboot in the first place.

I just install linuxcoin on a USB thumb drive, then ok the AMD agreement and cd / to the miner and run the command to start it.
Then I click AMDoverdriveCtrl and set the clocks.
Do the same for GPU no.2 and done.
No reboot for days, weeks.

So why do you want to reboot the PC? All settings can be applied without rebooting, right? It's not a Windows system

On a side note:
I have a 'limited' 5870 (BIOS clock limits) and have just saved the AMDoverdriveCtrl profile (GUI still running), edited the profile and loaded it again.
The limited card is now being successfully clocked past it's BIOS limits and is stable.

Now off to find the highest possible settings...

When I run this, the auto fan setting in the saved profile isn't applied.  When I run "AMDOverdriveCtrl -i 0 -b miner.ovdr" It returns the values in the profile and then returns to the command prompt.  I am running this from the root terminal.  the only way I can get the fan profiles to work is to launch AMDOverdriveCtrl -i 0, and then manually load the saved profile.  Then the terminal window updates with the fan speeds.  Any ideas here?  I would reallly like to get this to run from the command line so I can script it on startup.

It's a dual partition one, but it makes no difference since dd copies every sector from one usb key to the other so your copy ends up with the same layout of your source.

spiccioli.

Is that a thumb drive with a 1GB Fat32 partition and the rest configured with an ext4 one, or just one big Fat32 partition?

Thx!

Wherever you choose to save it.

4x 6950 @ 1731.40 MH/s under Linuxcoin 0.2.1b

Where are the profiles saved?

I just got Linuxcoin 0.2.1b up and running and it worked very well out of the box.  I must tip my hat to you on a great release.  I only had to make some minor changes (run aticonfig --adapter=all --initial -f again, change permissions/ownership on /opt/miners/phoenix/ , do svn update from within /opt/miners/phoenix/ to get the latest version with the +3% speed boost Ma() function, copy over the /etc/OpenCL directory from another computer because for whatever reason the AMD EULA popup never appeared and thus those files never got written, and then there's the unfortunate issue with /var/run/screen having the wrong permissions set with every boot).

But anyway, all of those tweaks took no more than 30 minutes, which is an excellent price to pay for getting access to Catalyst 11.6!  I have my four 5830s running at 960,335 MHz clock speeds now (up from a limit of 900 on Linuxcoin 0.2a with Catalyst 11.5).  Each one is pushing around 304-305 MHash/s for a total rig output of 1220 MHash/s.  That is way more than I ever thought these 5830s were going to be able to output, and they're all running at below 70degC to boot!

And you did a good job listening to all of the suggestions in here.  I don't see a one that didn't make it in.  Hell, you even included the firmware-atheros package, so 0.2.1b worked out of the box with my wireless card without even having to copy that driver over on a USB stick.  Very nice    I just sent you a donation.  You earned it!

That tip is much appreciated! I'm all for simpler & easier.

I preffer to use AMDOverdriveCtrl itself as command line interface than aticonfig. If you set up a configuration with the GUI of AMDOverdriveCtrl and save it as a profile, then you can load it into the card with this command:


Where X is the id (number) of the card and deviceX.ovdr is the name of the profile file you saved. You can even edit the profile text file manually and dont use the GUI anymore.
