Thanks for the info,
Here is what I ended up doing:
Replaced the board with Biostar TA785GE 128M version 6.1 Listed as AM2+ socket and "supports AM3" it fit fine ,uses a few less screws to mount to the case,
Installed Phenom II X4 965 125W AM3 ,
Started up fine with old Vista operating system,
Updated operating system to Windows 7 Home Premium
No problems using all existing wiring and connections to switches and components
I was surprised how easy and smooth it went
Thinking of updating the existing 300Wpower supply for good measure, but all seems fine for now
Plan to put the Bengal board in an older Medion computer with another Phenom I just came across
Thanks
