VCC5

– Lowering FSB impedance to 42 ohms is required.

‧

Increase FSB trace width accordingly on following signals:

– D[63:0], DSTBN#[3:0], DSTBP#[3:0], HDBI#[3:0]

‧

Maintain same center-to-center spacing No changes needed within CPU/MCH break-in/out areas

‧

Expect increased margin for all CPUs supported on the platforms

‧

– Following FSB signals are recommended to be no more than 4.3 inches on external layers: D[63:0], DSTBN#[3:0], DSTBP#[3:0], HDBI#[3:0]
