Bought a HD477AYDFC and 400W Corsair PSU to give my Core2 build away, which previously had a HD4870.
It takes 20sec to POST with the 4770 on both the P965 and P35 boards (the 4770 makes a squealing noise, not too much unlike a GPU running furmark during this).
But the main problem is I can't seem to change FSB. It rejects any manual CPU clock, even if I leave it at stock. If I let it boot into Windows with stock FSB, all is fine.. manged to overclock the 4770 from 750/800 to 925/1000, furmark stable.
If I swap the 4870 back in, all is fine.. can OC my E6300 from 1.86 to 3.15GHz.
I've tried 2 PSUs, Corsair 400 and 650W, both motherboards are on the latest BIOS, tried a different 4770 BIOS.. I'm out of ideas.
Seems like this could maybe be fixed with a BIOS update (the latest one for both these boards is almost a year old).. as the card does work perfectly once in windows.. or perhaps the card is in someway faulty?, I don't have a newer board(yet) to test it. :(
Any ideas?
