Intel S3000PT Product Specification - Page 15

Intel® Server Board S3000PT TPS Functional Architecture 3.1 Processor Sub-System The Intel® Server Board S3000PT supports the following:  Intel® Xeon® processor 3000 sequence  Intel® Core™2 Extreme Edition  Intel® Core™2 Duo  Intel® Pentium® Processor Extreme Edition  Intel® Pentium® D Processor  Intel® Pentium® 4 Processor  Intel® Celeron® D Processor The processors, built on 90nm and 65nm process technology in the 775 -land package, utilize Flip-Chip Land Grid Array (FC-LGA4) package technology and plug into a 775-land LGA socket (which is referred to as the Intel® LGA775 socket). The processors in the 775-land package, like their predecessors in the 478 -pin package, are based on the same Pentium® 4 micro -architecture. They maintain compatibility with 32 -bit software written for the IA -32 instruction set, while supporting 64 -bit native mode operation when coupled with supported 64 -bit operating systems and applications. The Celeron® Processor is not available with dual core, Hyper -Threading Technology or Intel® EM64T. 3.1.1 Processor Voltage Regulator Down (VRD) The Intel® Server Board S3000PT has a VRD (Voltage Regulator Down) to support one processor. It is compliant with the VRD 11 DC-DC Converter Design Guide Line and provides a maximum of 125A, which is capable of supporting the requirements for the following processors:  Intel® Xeon® processor 3000 sequence  Intel® Core™2 Extreme Edition  Intel® Core™2 Duo  Intel® Pentium® Processor Extreme Edition  Intel® Pentium® D Processor  Intel® Pentium® 4 Processor  Intel® Celeron® D Processor The board hardware monitors the processor V TTEN (Output enable for VTT) pin before turning on the VRD. If the VTTEN pin of the processors is not asserted, the Power ON Logic will not turn on the VRD. Revision 1.3 7
