Gigabyte GA-P67A-UD5 Discussion Thread

[Falkentyne]

I'm using F7. Besides the 22nm IB support, which will require an updated bios anyway, I was getting some strange issues with F3g, where the board would refuse to POST sometimes after a hard power down (would just power up for 10 seconds then power off). I was also seeing some strange things happening, like Windows 7 freezing after I choose "reboot", and then either powering off and on again, or just frozen at the shutdown or black screen. I noticed that bioses after f3g raised the default DDR voltage to 1.52v, so I did that and the problems went away. I then went to F7, zero problems with it besides the LLC being a bit erratic at times. Then I went to 16 GB of RAM (4x4 GB) and zero problems with F7, no boot loops, no cold boot bugs, nothing at all. I do seem to have coil whine coming from apparently the 6970...doesnt *seem* to becoming from the new seasonic 1000w psu at all (at least it doesnt get any more audible if I put my ear next to it, but who knows?), and the directions "seem" to point to the videocard. Probably harmonic resonance between the card and the PSU, since it didn't happen before I swapped psu's. Maybe I'll remove the card and try to turn on the PC without the card to see if that's it, but it will either error beep or boot loop without a card.

And most of the people seem to be in the UD4 or UD7 threads now. But all the rage seems to be the Z68 and X79...

Ok, the horrendous sound is coming from my Panaflo fan...out of all things...if I unplug the panaflo, everything is dead crystal silent....
