6. P5B STUCK ON x1 PCI-EXPRESS: Reported causes for this issue vary, however it seems the most common culprits are: A) Improper flashing procedure - OR - B) Overvolting the northbridge - OR - C) A PCI-Express clock not divisible by 33 - OR - D) A PCI-Express clock that's simply too high, even if at the in-spec 100MHz. It is imperative that you've followed the flashing procedures outlined in section IV-1/2/3. However, testing has revealed that setting the PCI-Express clock in the BIOS to 96MHz -- four less than PCI-SIG's recommended frequency -- is a very handy solution to this peculiar problem. Lastly, it is very important not to exceed 1.55v for the northbridge, although it is perfectly acceptable to maximize the SATA/PCI-E voltage in the BIOS. In virtually all circumstances, observance of these remedies can prevent or eliminate the issue. A 4MHz clock reduction is a 4% reduction with a performance reduction equal to the margin of error in 3D performance.
关键:北桥电压不要超过1.55v,PCI-E推荐频率96;
