Processor Uncore Data - Intel BX80569Q9550 - Core 2 Quad 2.83 GHz Processor Datasheet

System Management Bus Interface
6.4.3.3 Core Voltage
Offset 28h-29h is the nominal core voltage for this part, rounded to the next
thousandth, is in mV and is reflected in bcd.
Example: 1500 mV is represented as 1500.
6.4.3.4 Core Voltage Tolerance
Offsets 2Ah and 2Bh contain the core voltage tolerances, high and low respectively.
These use a decimal to Hexadecimal conversion.
Example: 19 mV tolerance would be saved as 13h.
6.4.4

Processor Uncore Data

This section contains silicon-related data relevant to the processor Uncore.
6.4.4.1 Maximum Intel
Offset 2Eh-30h provides maximum operating link transfer rate for the Intel
Interconnect. A link rate of 4.8 GT/s is expressed as 6 bcd digits in MT/s.
Example: 4.8 GT/s = 004800.
6.4.4.2 Minimum Operating Intel
Offset 31h-33h provides minimum "operating" link transfer rate for the Intel
QuickPath Interconnect. Systems may need to read this offset to decide if all installed
processors support the same link transfer rate. This does not relate to the "link power
up" transfer rate of 1/4th Ref Clk. This value is represented by 6 bcd digits.

6.4.4.3 Intel QuickPath Interconnect Version Number
Offset 34h-37h provides the Intel
bit ASCII characters.
Example: The Intel
QuickPath Interconnect Version Number 1.0. Therefore, offset 34h-37h has an ASCII
value "01.0", in reverse order.
34h: 30h, 35h: 2E, 36h: 31h, 37h: 30h.
6.4.4.4 Memory Type Support
Offset 38h signifies the type of memory support for this processor and platform.
A 01h signifies FBD1 support only (for Intel
®
Intel 7500 Scalable Memory Buffer support only, and 04h represents support for
