If the 3130 worked, then why is there a 3220 in it now?
Can you get the 2500K back to test a known good that worked?
Which stepping revision is the GD65?
The B3 revision doesn't support Ivy Bridge. The G3 revision does out of the box.
There is a BIOS update here (click me) that allows for Ivy Bridge support. Version should be P.1 from 2012-04-16. You'll need the 2500K or another Sandy to do the update, though.
