Introduction The Intel® Core™ i7-900 desktop processor Extreme Edition series and Intel® Core™ i7-900 desktop processor series are intended for high performance high-end desktop, Uni-processor (UP) server, and workstation systems. Several architectural and microarchitectural enhancements have been added to this processor including four processor cores in the processor package and increased shared cache. The Intel® Core™ i7-900 desktop processor Extreme Edition series and Intel® Core™ i7-900 desktop processor series are the first desktop multi-core processor to implement key new technologies:...

The processor is a multi-core processor built on the 45 nm process technology, that uses up to 130 W thermal design power (TDP). The processor features an Intel QPI point-to-point link capable of up to 6.4 GT/s, 8 MB Level 3 cache, and an integrated memory controller. The processor supports all the existing Streaming SIMD Extensions 2 (SSE2), Streaming SIMD Extensions 3 (SSE3) and Streaming SIMD Extensions 4 (SSE4). The processor supports several Advanced Technologies: Intel® 64 Technology (Intel® 64), Enhanced Intel SpeedStep® Technology, Intel® Virtualization Technology (Intel® VT), Intel®...

• Jitter — Any timing variation of a transition edge or edges from the defined Unit Interval. • Storage Conditions — Refers to a non-operational state. The processor may be installed in a platform, in a tray, or loose. Processors may be sealed in packaging or exposed to free air. Under these conditions, processor lands should not be connected to any supply voltages, have any I/Os biased, or receive any clocks. • OEM — Original Equipment Manufacturer.

Electrical Specifications Electrical Specifications Intel® QPI Differential Signaling The processor provides an Intel QPI port for high speed serial transfer between other Intel QPI-enabled components. The Intel QPI port consists of two unidirectional links (for transmit and receive). Intel QPI uses a differential signalling scheme where pairs of opposite-polarity (D_P, D_N) signals are used. On-die termination (ODT) is provided on the processor silicon and termination is to VSS. Intel chipsets also provide ODT; thus, eliminating the need to terminate the Intel QPI links on the system board....

Electrical Specifications ensure that the voltage provided to the processor remains within the specifications listed in Table 2-7. Failure to do so can result in timing violations or reduced lifetime of the processor. VCC, VTTA, VTTD, VDDQ Decoupling Voltage regulator solutions need to provide bulk capacitance and the baseboard designer must assure a low interconnect resistance from the regulator to the LGA1366 socket. Bulk decoupling must be provided on the baseboard to handle large current swings. The power delivery solution must insure the voltage and current specifications are met (as defined...

Electrical Specifications The processor uses eight voltage identification signals, VID[7:0], to support automatic selection of voltages. Table 2-1 specifies the voltage level corresponding to the state of VID[7:0]. A ‘1’ in this table refers to a high voltage level and a ‘0’ refers to a low voltage level. If the processor socket is empty (VID[7:0] = 11111111), or the voltage regulation circuit cannot supply the voltage that is requested, the voltage regulator must disable itself. The processor provides the ability to operate while transitioning to an adjacent VID and its associated processor...
