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 h.

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.

This section contains silicon-related data relevant to the processor Uncore.

Offset 2Eh-30h provides maximum operating link transfer rate of 4.8 GT/s as 6 bcd 
digits in MT/s. Example: 4.8 GT/s = 004800.

Offset 31h-33h provides minimum “operating” link transfer rate. 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.

Offset 34h-37h provides the Intel QuickPath Interconnect Version Number as four 8-bit 
ASCII characters. 

Example: The Intel Itanium processor 9300 series supports 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.

Offset 38h signifies the type of memory support for this processor and platform.

A 01h signifies FBD1, 02h is Intel

®

 7500 Scalable Memory Buffer, and 03h represents 

support for both memory types.

Offset 39h-3Bh provides maximum memory transfer rate. Systems may need to read 
this offset to decide if processors and Intel 7500 Scalable Memory Buffers support the 
same FB-DIMM transfer rate. Six 4-bit BCD digits are used to provide the maximum 
transfer rate in MT/s.

Example: A speed of 4.8 GT/s is shown as 004800h.
