Thought I would give an update. After adjusting the power settings and doing some specific troubleshooting I have gotten the rig stable for 24 hours.

I took fullzero and Maxximus007 suggestions on the power settings and give it a bit more with more modest OC. It seems to have resolved the issue, as well I have found that one of the cards was not liking bigger OC's while the other 5 worked fine.

This was the outcome.

As for the settings, I have the following settings:
5 cards:
Overclock
cc 100
mc 1275
Powerlimit: 125 watts
1 card:
cc -100
mc 1225
Powerlimit: 120 watts
(this card does not like OC had to tweak it some for it to not cause instability within the rig)

Total watts from the wall: 866/867

I am still taking fullzero advice and adding 4 GB more of RAM it will be here in the next few days.

Maxximus007 or fullzero if you have a BTC,ETH address I would like to send you a small thank you for the help on troubleshooting.
