It's a very nice board but I have some issues with it.

1. Under 100% load the CPU temperature which reported by the mainboard is approximately 10-12C degrees more than the cores temperature (which reported by the CPU itself eg. via AOD). I think it's an unreal value and it causes some trouble. (eg. higher CPU FAN speed than necessary)

2. When the CPU temp (which is incorrectly reported by the mainboard) reaches the approx. 64-70C degrees the system automatically switches back the CPU's multiplier to 6.5x (1300MHz). It results that the systems slow down significantly. (The Cool and Quiet is disabled in the BIOS.) I haven't met this kind of thing on DFI or Gigabyte boards.

3. When I do a Save&Exit in the BIOS the hard drives and the fans stop and suddenly start again (like a very quick power off/on). I think it may cause damage to the hard drives.

4. The motherboard overvolts the CPU under load. For instance when I set 1.35V in the BIOS it means 1.39V under 100% load (reported by PC Probe).

5. The "Advanced Clock Calibration" option in the BIOS has no any effect. Nor yet the overclocking is worse when I turn it to auto or +2%. When I set it to +4% or more the system can't start at all and I have to do a CMOS CLEAR.

CPU: 9950BE 125W
RAM: SuperTalent T1000 2x1GB
PSU: Corsair HX520

BIOS: 0403

I hope that ASUS will fix this issues soon.
