| Q: | Why can't the BE7II motherboard boot up? Doesn't it support the older 400 FSB P4 processors? |
| A: |
The BE7II follows Intel's recommendation to use new power design VRD10 for
Intel 845PE boards. According to the design guidelines, the CPU core voltage
range is from 0.8375 to 1.6000 V. If an older 400 FSB P4 or Celeron processor
with a CPU core voltage of 1.75V is installed to BE7II board, the board cannot
provide such a high core voltage and the CPU will malfunction. That's why Willamette
and old Celeron processors are incompatible with Intel 845PE boards. The 400
FSB processors that work on a BE7II board are Northwood P4 (512K L2) and Celeron
2G (128K L2, 1.525/1.530 V) and faster CPUs. The supported CPU list is as follows: Intel Socket478 Pentium4 (0.13 micron, 1.525/1.530 V, 512K L2), up to 2.6GHz (400) Intel Socket478 Pentium4 (0.13 micron, 1.525/1.530 V, 512K L2), up to 3.06GHz (533) Intel Socket478 Celeron (0.13 micron, 1.525/1.530 V, 128K L2), up to 2.6GHz |
