If you are having these types of problems without any overclocking, you have one or more of the below:

A - defective hardware
B - severe thermal problems with your design
C - insufficient power supply

check all that apply.  bamt will not work properly on this system until above issue(s) are resolved.

never heard of GPUs that have to wait before they will work again.  I suspect you have some damaged goods there Sad

B - I think the system is rebooting for high temp, but even after the cards are cool system still won't start. The only way I can make it start is by removing each card until I find the one with issues.
C - My rig has 3x 5970 (3x 350w = 1050w) and 1x 5870 (190w), so 1050+190+~200 for other components totals 1440w. I'm using 2x PSU BQT-PRO8-1200W, that gives me a total of 2400W. That should be enough, only way I coud see the PSU being the problem is that it's 2nd hand and could be defective but I think that's unlikely.

Could my rig be restarting as a result of some BIOS setting? I had one time where the system crashed and restarted. Then it wouldn't boot up and I did a BIOS reset and it booted normally again. That's why I suspect the motherboard could be causing all this.

I have purchased my PSU's and video cards 2nd hand, so it might be possible that they're defective.

But I'm also using cable extenders and a no brand motherboard that are also candidates to be causing these issues.

For example I have one 5870 that will not work when connected via extenders, but works flawlessly when connected directly to the X16 slot. On the other hand, my 5970's work without issue on the very same extender.

So I guessed my extenders are fine, just not compatible with some cards. Perhaps due to some interference caused by longer cables?

I'm having difficulty troubleshooting this because it seems to have too many variables/candidates to be causing these issues  =/

Hmm, I will do that. Right now I think my system is on "auto", that means I haven't set OC on bamt.conf so I guess it's on auto-pilot.

I will be looking in the forums what are the best settings for Gigabyte 5870 that I have here.

By the way these locked cards how to make them work again? They seem to work again if I wait a long, long time before using them again. Any other way?

Almost forgot to ask, is it possible to prevent BAMT from restarting automatically?

I've been running BAMT here and my Rig will restart every couple of hours by itself, I think it's due to high temp on some cards.

Problem is when it restarts, it can't boot up as some of the cards seems locked and the system freezes when loading X.

When this happens I can only make it boot by removing the locked card from the rig...

Anybody with similar issues?

anybody else who overclocks their cards way too much will have similar issues. 

reduce overclocking.

Thanks Joshwaa, atitweak works.

Thanks mc_lovin, yeah there was a file and a little note, i deleted it - afterwards it worked

mother disabled overclocking on this GPU due to a defunct phoenix process at Thu Jun 14 13:14:02 2012

Also when using atitweak make sure to always use "-P 2" that way you do not mess with the wrong power level.

that little note means your rig locked up and BAMT restarted it.  reduce overclocking, or expect to see it again.

I got a 5970 but i am not able to downlock the memory on GPU1, only on GPU0.

Is there a special trick to make this happen?
are there any files in

/live/image/BAMT/CONTROL/ACTIVE ?

30 BTC sent for the 7970 integration!  Looking forward to the bamt revamp!

edit: donation is on behaf of wtcr.ca, online bitcoin computer store !

very nice, thank you.  we now have enough for the GPU so I'll be getting this started soon.

why dont you pm me a banner ad or something and we'll put you up on the bamter.org site.  that goes for any other folks that have donated and would like to have some recognition.

done and it looks great on the site there, thanks again!

I'd like to try using cgminer instead of the default miner. The config file says " (see full example for how to use cgminer instead)". Where can I find that full example?

Code:
$ ls /opt/bamt/examples/

Thank you!

I strongly recommend you *do not* implement a scheme of powering your mining rigs on and off every day.

a vast majority of the USB key wear occurs during boot up.  you will accelerate the death of your usb keys tremendously.  if you're so worried about power that you can't run a box at idle, you're in the wrong hobby (or the wrong location, at very least).

I'm guessing power is quite expensive at Cray-1:s location, since mining isn't profitable at "peak demand" time. Having three rigs using 500W (total, my estimate) doing nothing at that time seems wasteful.

How about suspending to RAM? That should save power without really rebooting the computer, thus avoiding the wear on flash memory.

maybe.  finding a better location or realizing that mining is not practical where you are sounds like a more sensible solution.  in any case, cron is the tool one would use for any regularly scheduled action.

cron jobs are the correct solution.  time to figure them out.

Can you turn the computer on and off with cron jobs? I don't think it's enough just to stop mining, even idle cards can pull something like 30W.

you can turn it off with cron.  back on could be done simply with a setting in the bios to power on @ certain time.  that would at least avoid the inevitable filesystem corruption and other issues that stem from simply cutting power to a running linux box over and over.

however, I strongly recommend you *do not* implement a scheme of powering your mining rigs on and off every day.

Make a cron job that does "stop_mining" and "start_mining"

that is exactly what I would do, yep.
