Split Plane for vcc?

[Wallysaurus]

Foot note 9 in the Intel SSpecs:"Reqires a motherboard with a split plane for the vcc". Could someone explain this to me. Thanks.

Foot note 9 where?

Split plane voltage was used for the Pentium MMX....a motherboard needed to supply both 3.3 and 2.8 volts to the processor, as it used different voltages for different parts of the processor, reducing power consumption in comparison with the original Pentium.

No current Intel P6 class processors (PPro, P2, P3, Celeron) require split plane voltage. Not sure about the P4.

I have the same question. Will my BX board propoerly support cC0 or should I look for cB0 which doesn't appear to have the same requirement?

Andy,
According to the Intel SSpec sheet all cCO P3's need a Vcc core voltage of 1.7v and reqiure a motherboard with a split plane for the Vcc.
