Processor Population Rules
When two processors are installed, both must be of identical revision, core voltage, and
bus/core speed. When only one processor is installed, it must be in the socket labeled CPU1.
The other socket must be empty.
Processors must be populated in sequential order. Processor socket 1 (CPU1) must be
populated before processor socket 2 (CPU2). No terminator is required in the second processor
socket when using a single processor configuration.
The board is designed to provide up to 130 A of current per processor. Processors with higher
current requirements are not supported.
2.2.3
Processor EVRD
EVRD11.0, Enterprise Voltage Regulator Down, is a DC-to-DC converter that meets the
processor power requirements server platform. Processors supported by this VR are: Intel
5000 sequence processors and future processor technologies
EVRD11.0 incorporates functional changes from prior EVRD design guidelines.
2.2.4
GTL2007
The GTL2007 is a customized translator between dual Intel
system health management, Intel
LVTTL and GTL signals. The GTL2007 is a 12-bit translator to interface between the 3.3-V
LVTTL chipset I/O and the Dual-Core Intel
GTL / GTL+ I/O. The device is designed for platform health management in dual-processor
applications.
2.2.5
Common Enabling Kit (CEK) Design Support
®
The Intel
board complies with the Intel
thermal solution. The server board ships from Intel's factory with a CEK spring snapped onto the
underside of the board beneath each processor socket. The CEK spring is removable to allow
the use of non-Intel heat sink retention solutions.
