I'm getting troubles trying to have a Q9550S processor working with a DP35DP motherboard.
The machine's stuck before post at the first startup try; it boots up at the second try but it looks like the processor temp isn't correctly recognized (it's displayed a fixed value close to the thermal margin). Every time I try it boots only at the second istance.
I double checked CPU heatsink and thermal compound. The processor works good on another motherboard.
DP35DP BIOS is up to date.
Sorry, I've found out this has already been discussed.
Sorry again, I posted the message above without login.
