Ok so I found a setting to increase the frequency of the PCIe Bus in the BIOS settings. I upped it to around 110, turned off a few settings that appear to restrict the power for "green" purposes, put both cards (which are now diamond 6870's) in, default settings with -v -w128 and I have 15 minutes of constant hash power...I think I may have done L and G.
Note: Prior to the above solution, I reinstalled all MB drivers, and ATI drivers Etc....they were still crashing.
Thank you all for brainstorming I hope that the pcie frequency helps some people...
I guess I should state that you can F your board up by raising this too high... That being said, the default was 100 i turned it to 110 and the max it will let me is 190 (not that i have tried that, i havent tried above 110). If anyone knows more abot this or can confirm that this solved my problem then please let us know. Also is it possible to raise the performance of our gpu's by increasing this frequency.
