I'm currently testing out my new DFI Ultra-D. Same basic setup as before. I flashed to the latest BIOS and learned my way around the BIOS. My problem is this... the darn thing makes my San Diego run hot, very hot! I'm using the same cooling setup as before and using the same OC settings as with my EPOX (HTT, voltage, divider, etc). My OC is stable, but my CPU is now loading at 56*C. With the same voltage of 1.65V on the vcore my San Diego used to run at 45*C under heavy load (on my old EPOX). With the same voltage on the DFI it now runs a full 10*C hotter. I already reseated the heatsink with a fresh application of AS5, I even switched with my old XP-120 and still the same. At stock voltages it loads at 40*C (it used to run at 36*C load even after the fact that the EPOX overvolted the chip by .1V). Any ideas? I really like this board (I'm able to OC to 3.0GHz!!!), but I will go back to the EPOX if I can't resolve this.
