The story I read was that some cards consume a lot of power such as the 6990, so much so that the PCIx slot cannot supply enough and so the molex is added to extend the amount of power supplied to the pcix port.  Basically it's for the dual gpu single slot cards.

You should include information like what operating system you are using, if you are using windows, you need dummy plugs. http://www.overclock.net/folding-home-guides-tutorials/384733-30-second-dummy-plug.html This is how to make them.  If you are using linux and you typed something like aticonfig -i in a root terminal and got only one active, than it could be a hardware related issue (maybe the cards aren't in their ports correctly).

 

I tried that a few times myself, I got instant bsod, thankfully the cards have that bios switch.  I assume you are talking about method 2 on the additional features tab.

This is a great blog Smalleyster.  I especially loved the part where you wrote "Tomorrow I plan to re-format the USB," it was enthralling.  Bravo.

Hah, this sounds like extremely old news to me.  There is a group of bankers who seek to control the entire world with the concept of debt.  The governments are part of their structure, as is many other things as well.  The bottom line is simple and clear.  If you can agree with the sentiments of this video, and you can agree that the governments are in cahoots with said banking regimes, than you must state that the goverment and their bankers are incredibly evil and corrupt.  What do you do to and with evil and corrupt things?  I'll leave that to you.

P.S. Stop watching the news, they own it.

It seems ati tray tools can only support 2 cards, msi afterburner can do 3.  However, I think you may be able to get around this problem by connecting the two with a crossfire bridge.  I read that being suggested some where, I haven't tried it myself.  I just took one of the cards out and put it in another machine.  Linux can do 4 cards, but I can't seem to get around 'Configurable Peak Range'.
I also read that crossfire might slow it down a little.  I had a few cards in crossfire not long ago, I am not sure if they really mined any slower.

Only if that card is used for the display.  If the card is what is connected to your monitor, than that is to be expected, doing anything on the machine takes some processing, generally of both the cpu and gpu, some things more than others.

Ferrets, from what I've read, don't like to be much hotter than 80 degrees.  I am not trying to scold you, but a -lot- of people get ferrets with a terrible lack of knowledge concerning them.  Ferrets are much happier in pairs, they need lots of space, attention, love, and possibly the most commonly overlooked detail of concerning ferrets is what they eat.  Several of the ferrets I've come across were handled poorly, it is a shame.  Plenty of ferrets love to snorkel.  They don't actually have a snorkel on, they just submerge their upper body into the water and move their head around.  They prefer clean water though, in a glass dish.

Obviously, heat management is an important detail concerning most electronics.  If you are serious about mining and the well being of your ferret, I recommend putting together a sort of box or trap for the heat.

I am thinking cardboard (for cost and something that someone with an apartment could probably put together).  Using lots of duct tape, a few well placed holes in the box setup, and the boxes venting straight out the window with it all sealed up and a few fans sucking the air out of the box, you'd have a fair amount of isolation going on without heating up the contents of the box.

The most simple and obvious solution is (as I am trying to draw for you) is to vent the heat to the outside.

I was under the impression that crossfire created problems, don't ask me what they are.  Seemed like slow downs or maybe something like that.

I guess I don't understand how.  I've used 11.6 plenty, but I've never had success getting passed the 'normal' range.  Is there a list of commands?  I use things like "aticonfig --od-enable" "aticonfig --odsc=GPU,mem" "aticonfig --odgc" and so on, but I don't seem to be able to get that to work.

Hah, yeah, I came to the same conclusion.  I was irritated as hell when he gave some answer factually like he knew what he was talking about and as though it would work.  A real waste of time.  What a $*%&.

I feel similarly to this sentiment.  Being concerned about ddos, pool failure, or a pool getting 'too large' crops up in my mind and draws me to the smaller pools. 

Hello,

I have a later model (6xxx) graphics card and I have been struggling to get beyond their bios established voltage and clock ratings.

I tried for about a week to get passed 840mhz for the core in linux distros, but it seems impossible.  I tried a few times to modify the bios in RBE and then flash the card using 'method 2' but both attempts I kept getting instant crashes.  ATI tray tools and msi afterburner both work great, however they both are extremely limited.  Their software ability is robust but how many cards they can handle are not.  As far as I know, ATI tray tools can only handle 2 cards at a time where msi afterburner is only capable of handling 3.

This makes overclocking very difficult if you are using a 4-6 card setup, and impossible in linux.

Does anyone have any knowledge they'd be willing to share on how to get passed the bios rated limit in linux?

I've searched, tried, and yelled this idea to death alone.

Thanks

How did you come to this conclusion?  How do you know that ccc is disabling msi afterburner when you have 4 graphics cards installed at once?

Some say you get better performance mining in linux versus windows.  I can't vouch for that claim myself.  The biggest problem I've had for mining in linux (beyond learning how to use linux itself) is overclocking in linux.  AMDoverclockctrl seems to be the way to go as far as overclocking in linux goes.  However, 6950s are limited to 840mhz for the core through the bios.  As far as I know, there is no way around this for software in linux.  Windows has several programs that will allow you to bypass the bios limit.
It looks as though a bios modification program called RBE for windows has some options that I am looking into myself.  It looks like there might be possibility, but I am not sure if it's really worth the hassle and risk of reflashing with a bios I modified myself.
If any of you look into RBE bios modification in terms of the increasing the overdrive limit and such, be sure to open RBE and read the warning concerning 'method 2 - no hash'.

There is a 'clock settings' tab on RBE, but I am not sure if you can go over the limit with just that alone.  It looks promising, but there is risk involved and I have too much uncertainty concerning the idea.

Hello,

I've been trying to figure out how to get to a higher overclock than 840 for my video card but have so far been unsuccessful.

First, I load a root terminal and enter "aticonfig --od-enable".  Then, I load AMDOverdriveCtrl and make some modifications to the best levels allowable on the software.  I then save the profile and then open the profile with leafpad.  I modify the profile to have suitable clock settings for the GPU and save it.  When I open another root terminal and attempt to load the profile 'AMDOverdriveCtrl -i (insert number of a gpu here) -a (insert chosen profile name here).ovdr' I get an error.  "Overdrive Error Could not apply overdrive settings."  I have the powertune settings at 20%.

Basically, I don't seem to be able to go above the allowable defaults.  I've done plenty of reading and finding this "aticonfig --od-enable" excited me, thinking that was the solution to my problem.  I thought I was so clever when I modified the profile with leafpad, haha.

AMDOverdriveCtrl -i (insert card number here without ()) -a (insert file name of saved profile name)

This is what it might look like.

AMDOverdriveCtrl -i 0 -a cardsettings.ovdr

I am a total linux newbie myself, however, I managed to modify a .ovdr file or card profile hoping to get past my overclock limit.  I've seen this question asked several places but nobody seems to have an answer, it makes me doubt there is a way.  My card has an over clock limit of 840 mhz for the core.  I know I can crank it up to 1000 mhz stable but I don't seem to be able to do this within the AMDoverdriveCtrl GUI.  Opening a .ovdr file or profile file with leafpad you can see the settings.  I modified them with my own settings which I was pretty excited about.  I thought I had found a solution, but I get an error.  "Could not apply overdrive settings."  I have the powertune at 20% and the file says the same thing agreeing.




  
  
  
  
  
  
  
  
  
  
  
  
  
  


That is the content of the profile.  I am using linuxcoin .2b.

I am starting to think that I am going to have to flash the card to get to higher settings, which doesn't excite me.

I've searched pretty hard but clearly I haven't found a way to get past the locked settings in this program, I wonder if anyone has any ideas.

Thanks

I finally got some mining going in linuxcoin.  My problem stemmed from the syntax (or lack of) during one of the options.  

I type start_mining in a terminal (bottom left coin, click, accessories), enter option 1, and for the option 'Enter url and press enter' I use something like this 'poolminingwebsite.com -p 8334'.  I was trying something like poolminingwebsite.com:8334.

The name and password are pretty obvious and need to explanation.  For some reason, before all that, when I would type all this into the terminals options, the terminal that would open to display the mining information would open and close instantly.  It wasn't until I opened ati sdk license and amd overdrive did it actually not just close instantly.  I opened the ati sdk license thing assuming that that was the problem, tried to mine a few times with no success, then opened the amd overdrive ctrl program and then I made some progress.

I still haven't figured out the phoenix thing.  A few seemed to mention hashkill being really good as well, maybe I'll give that a shot.

Also, I am still trying to figure out the persistence thing, 'sudo df' did give me a list of stuff.  However, '/dev/sdb1 10520641051712 352 100% /live/image' is the only line that seems to relate to anything further.  I see nothing relating to 2 sets of 4 random numbers and letters.  Perhaps I'll reformat the flash drive just to be sure I followed all the steps correctly.


@no_alone Thanks for the response.  I was under the impression that phoenix might be capable of giving better mhash performance, which is why I am eager to compare.  I have tried both of those options for the kernel option but the mining terminal opens and closes instantly.  This doesn't happen when I choose option 1.

As I've noted previously, I am a complete linux newb.  I am pretty sure many obvious details are sneaking past me, I am sorry for asking to have it spoon fed to me : P.

Hey guys,

This seems like great stuff but I seem to be struggling to utilize this and that.  I am very newbish to linux but I have used a fair share of command line in windows myself.  

Firstly, I saw the persistence guide a few moments ago and followed it up until the point where I am asked to open a root terminal ( I am certain I opened a root term ) and enter sudo su- df.  I have tried several variations of this command and have come up with 'unknown user: df' as the most promising and 'unknown command' as the most common.  I don't know if anyone else came across this error, if it is some mistake on my part or whatever.  Any help would be appreciated, thanks

I am excited about .2b, I wasn't able to get mining going in .2a, I did 'start_mining' but I think I may have been missing what to put into the 'kernel' portion.  I tried opencl and something else having to do with phatk or something (words found through searching), but had no success.
