I have a miner running BAMT .5 on a gigabyte 970a-d3

it currently has 2 5870 and a 6950 NOT overclocked

it will run for about 2-3 hours then says it has detected a problem on all 3 GPU's

i have tried each card seperatly and taken cards from another miner which has been running for atleast 2 weeks no problem

I have also swapped the motherboard with another identical board and they are both brand new.

all cards are on either a 1x-16x or 16x-16x riser cable

when it crashes i get the red screen but the system is responsive just not the network (cannot ping out or in or SSH)

if i reboot it is fine for another 2-3 hours also if u just hibernate and bring it back up it is fine but if i just restart the networking it does not work.

i have also re-installed bamt on several different brand USB drives same problem.

could anyone give me some suggestions to what this could be ands how to fix it.

i worked around the boot problem with this fix
