So I've started mining for alt coins with a 5870 and a 6950 in my rig. I did a little test run without optimizing anything to see if they could handle the load (I just set the intensity at 17 for both of them and left them alone for a day or so). Seemed like they were fine. So afterwards I did a little overclocking (and I really mean a little, like 50-100 mhz overclock), I raised the intensity to 18 for the 5870 and 19 for the 6950 and left them alone. A few hours later I come back and I see that the 6950 has spit out some hardware errors (I think it was around 4), so I lowered the intensity and tried again. This time it spat out double digits instantly. So I removed my overclocks and set them back to 13 intensity for both. Now they're both spitting out hardware errors right when I start CG Miner. So I've been troubleshooting for the past few hours, looked through forums for solutions and I've removed CCC (I had the most recent one) and reinstalled 11.1 and 12.1. Didn't help, CG miner was still showing hardware errors. So I tried using an older version of CG miner and for some reason the hardware errors stopped. Is there a reason for this? I'm stumped as to what caused the hardware errors to continue. And on a sidenote, can these hardware errors actually harm my cards? If you managed to read all the way to the end, I applaud you and thank you.

What command options have you specified?

I would also consider going back to the basics of just using
cgminer -o 'insert URL here' -u 'insert username' -p 'insert password' -I 7 -k 'kernel_of_choice' --auto-fan -d 0 --remove-disabled
tuning that one cad and then doing the same with the other by using -d 1 that way you then have a good set of parameters for both that you can then run together and raise the intensity until you get hardware errors, driver crashes, etc
