Another update......
Just installed a DT029 mobo, with BIOS Rev A02 and it works fine with the above two quad-core processors. But again I will reiterate I had -2- pins this time bad on the CPU socket 1. After busting out the magnifying glass and a needle, I was able to bend the pins back into their proper position. So, if your second quad core isn't working, make sure to check the socket pins!
I had a scare once when booting it said incompatible processors, so I opened the case and popped the CMOS battery out. The system boots just fine and runs fine without the CMOS battery. So, if you go the route as prev posted, there is no need to put it back in. You do have to babysit the booting process and go in and set the system date and time. But once you've done this, assuming you are running winblows, just Sleep your system instead of Shutdown and you won't have to deal with setting bios system time again.
...but then I realized it wasn't a system issue....I had left my thumb drive plugged into the front USB port and that's what was causing the incompatible processor message! I removed the flash drive and popped the battery back in, no problems since.
