Intel SE7505VB2, Continued
Many fixed-voltage regulators ensure stability
Intel provides each of its Xeon processors with a four-phase voltage regulator. Thus considerably less heat is generated than with a two- or three-phase regulator and it gets by entirely without a heat sink.
The P64H2 bridge controls the parallel PCI-X and PCI64 slots
The board is equipped with the P64H2 chip and has two PCI-X100 (A and B) and one PCI64 slot (C). It's a mystery to us why Intel does without a 133 MHz PCI-X interface in the server segment.
Intel relies on its very own 82540EM Gigabit LAN controller
The 82550PM is used for the 100-Mbit connection
Both LAN interfaces on the I/O shield
The board is fitted with Intel's 82550PM (100 Mbit) and the 82540EM (1 Gbit) network controllers. The 1-Gbit LAN chip is connected to the P64H2 Southbridge and runs in 32 bit mode at 66 MHz.
