So here's a question.. i was thinking to myself: well used is fine so long as it has a warranty.
so then i'm thinking "how do you submit a warranty claim with no receipt".  but then I realized it would be the same whether I the new one or the used one..
Anyway, I'll buy the used one from you if its got a warranty that I can use in the event it dies.. not sure if that is even possible tho.

If you want the Diamond HD7970 that I have that has been in a machine for a week I will give it to you for 67.5BTC If you want a new in box yea best I can do is 72BTC.

We have enough btc donated, just been busy. 

Amazon has em for $450 plus a lame $20 rebate that I'll never get around to submitting, seems to be the price pretty much everywhere..  http://www.amazon.com/dp/B006UACSZ4/ref=asc_df_B006UACSZ42067048?smid=ATVPDKIKX0DER&tag=hyprod-20

72 seems high, but maybe btc moved since that estimate.  I'd rather keep it in btc so lemme know if you can match amazons price or close, and if so we'll do this thing.

One bad GPU can lock up the bus and prevent the rest from mining.
Remove or swap between another machine until the problem goes away or moves to the other machine.

Next time it fails I will test the internet.  Thanks for the advice!!

I have two 7970s running in BAMT 0.5c but I can't seem to get the BAMT scripts to start the mining, I have to do it manually but it still reports the speeds to mgpumon... however the 7970 integration mining fund has been completed and lodcrappo will have the updated version soon.

I think Lod said it was funded. Im waiting to hear from him I got a Daimond HD7970 I was gonna send him for 80BTC (well 72BTC now since price went up). Unless some one promised to pay and has not come thru yet.

I think there was a bounty, don't know where it's at though. (% Funded)

When it "goes red" do you still have access to the internet? For example, can you open Iceweasel and go to Google? I was having this issue too, turned out to be this strange "lost the DHCP lease" issue that has been going around but hard to pin down. I put an old Intel Pro/100 card in and the issue has left that rig.

I havent checked BAMT for a while,... sorry if this is already covered.

Has anyone successfully run 7970s with BAMT?

Even with latest cgminer? I guess you also need to update to the latest SDK? (is it possible to update SDK in Bamt?)

I am having trouble with one of my rigs.  Approximately once per 24 hours it stops mining and displays the “Red Screen” stating  "A fault has been found in gpu x" for all five GPU’s.

I am running a msi 890fxa-gd70 with 5 Saphire 5830’s and a Cooler Master 1200w under BAMT v0.5c.  I have 3 other near identical rigs that do not seem to be having any problems.  The rig will be running fine and then just stop mining and give me the Red Screen.  I can determine no pattern as to when it stops working.  I have been having this problem for a while so the first thing I did was stop all overclocking.  This did not help.

Here are some clues, any help would be appreciated.

1.   While in the red screen I went to BAMT control and clicked on Stop Mining (this seemed to act normal).  Then I clicked on Start Mining and the start screen seemed to be acting normal.  When I went to GPU status screen it displayed all 5 cards producing 0 M/H.
2.   While in the red screen I went to a windows computer on the same network and ran Putty.  Putty was not able to communicate with the problem rig.

I have switched out the BAMT usb drive – does not help.  I am not overclocking.  It must be hardware (motherboard?) or the power supply, I guess.  The bios on the mobo has been updated to the latest approved version.  What tests can I run to narrow this down?  Thanks

That error is a result of your SSH client trying to forward X packets, not any particular setting in BAMT.

No, it's not failing.. I don't fully understand it, but X is what BAMT uses for it's video display..  Your best bet is flash the USB again and try again.  Also, are you using a monitor?  Your best bet is flash the USB fresh, plug it in, and turn on the rig with no monitor connected and use PuTTY to SSH in and configure it.  If it still says Xauthority, flash it again. 

I'm getting this error:


And when this happens, gpumon shows no card at all. And load unusually high at 8..

Sounds like my usb flash drive is failing?

You can also use the tarball from Inaba:

You just need to run the update script.

Thanks for these instructions. Always wondered how to upgrade cgminer to latest version in BAMT !

I updated BAMT with the latest version of cgminer. This is how I did it. I'm sure there are more elegant or "correct" ways, but this worked for me. If I'm doing something horribly wrong, please point it out.

Logged in as root, type this into a terminal to download the latest cgminer and prepare it with the ADL SDK:


Keep going. The following instructions on compiling cgminer are taken from http://ck.kolivas.org/apps/cgminer/README


Now that cgminer is compiled, you need to replace the cgminer that came with BAMT with the latest version. It's a good idea to stop mining before doing that, and to make a backup of the old cgminer:


Now restart mining and verify that things work as they should:


You should see the latest version of cgminer running in a screen.

Thanks so much for all the insights lodcrappo and for BAMT as well of course 

It seems to work well and quite stable with only 1 card, I might be putting stress on the parts by pushing the limits with 4, even 5 cards I have tried on this cheap motherboard.

I noticed something interesting, if I add 4x 5970 it won't boot up, it will always freeze at the time it's loading X. Not sure why, the kernel was supposed to support 8GPUs which is exactly how many I'd since each 5970 has 2 GPUs.

Maybe it's drawing too much power from the PCI-E slots? My system might get more stable if I use 2x 5870 + 2x 5970 instead of 4 or 3 5970 like I'm doing now. I plan to try that soon.

sounds like a system that is going to take a lot of time.  if it were me, I'd tear it down to one GPU, get that working stable, and add stuff back one part at a time.  no easy fix.
