| Q: | Why couldn't VI7 motherboard boot up? Doesn't it support the old 400 FSB P4 processors? |
| A: | The VI7 follows Intel’s recommendation to use new power design VRD10 for VIA PT800 boards. According to the design guidelines, the CPU core voltage from 0.8375 to 1.6000 V. If an old 400 FSB P4 or Celeron processor with CPU core voltage 1.75V installed to VI7 board, the board could not provide such high core voltage and the CPU will malfunction. That's why Willamette and old Celeron processors are incompatible with VIA PT800 boards. The 400 FSB processors which could work on VI7 board are Northwood P4 (512K L2) and Celeron 2G (128K L2, 1.525/1.530 V) and faster CPUs. |
