Functional Architecture
3.1.1
The baseboard has two VRDs (Voltage Regulator Down) providing the appropriate voltages to
the installed processors. Each VRD is compliant with the VRD 10.1 specification and is
designed to support Intel
105 AMPs and peak support of 120A.
The baseboard supports the Flexible Mother Board (FMB) specification for all 800 MHz FSB
Intel
requirements. FMB is an estimation of the maximum values the 800 MHz FSB versions of the
Intel
specifications for future processors may differ. At present, the current demand per FMB is a
sustained maximum of a 105 Amps and peak support of 120 Amps.
3.1.2
The BIOS determines the processor stepping, cache size, etc through the CPUID instruction. All
processors in the system must operate at the same frequency; have the same cache sizes; and
same VID. No mixing of product families is supported. Processors run at a fixed speed and
cannot be programmed to operate at a lower or higher speed.
3.1.3
Logic is provided on the baseboard to detect the presence and identity of installed processors.
In dual-processor configurations, the on-board mini Baseboard Management Controller (mBMC)
must read the processor voltage identification (VID) bits for each processor before turning on
the VRD. If the VIDs of the two processors are not identical, then the mBMC will not turn on the
VRD. Prior to enabling the embedded VRD, circuitry on the baseboard ensures that the
following criteria are met:
3.1.4
The GTL2006 is a 13-bit translator designed for 3.3V to GTL/GTL+ translations to the system
bus. The translator incorporates all the level shifting and logic functions required to interface
between the processor subsystem and the rest of the system.
