The 9850BE seems to have no trouble running at 3Ghz all day. Its the DFI 790FX-M2R that seems to be having a schizophrenic time handling the 9850.

  1. The system will consistently RUN at 3Ghz.
  2. As Nico pointed out in his TTR post, it does NOT always like to BOOT to 3Ghz
  3. I can get it to boot to 3Ghz by having CPU voltage set to 112.82%, yielding 1.45V, which is somewhat high, but not ridiculous (I'm on water, although I'd be dubious about doing this on air)
  4. There is definite MISMATCH between AOD, Smart Guardian and Everest on many IMPORTANT readings to tweakers and modders. A variety of voltages are simply inconsistent
  5. One PECULIAR item of note, is that I boot using the BIOS voltage setting of 112.82%, which yields 1.45-1.47 volts in SG and Everest. the MINUTE I start up AOD, the voltage DROPS to 1.38-1.39 in SG and Everest.
  6. AOD definitely has value now with Phenom, but the BIOS and AOD do not agree. Voltages are clearly not the same in both.


All in all, my confidence with the Phenom is starting to grow. Its pretty obvious that more experience and testing is needed to further the development of Firmware for these motherboards, and to tighten up integration between AOD and BIOS.

Its clear to me that there is something that happens at boot time, that is different than run time as it relates to CPU state. My simple mind might drift towards there being some kind of voltage drop during boot up that causes the CPU to not be able to tolerate 3Ghz at bootstrap, causing BSODs. But after about a minute of steady state, the system runs just great and will Prime all night.
Yup...they have to warm up, i found the same

There is new bios on the way from DFI I hear, we just need to wait and see what they managed to fix
