Features 7.4.3.3.3 MPSUP: Multiprocessor Support This location contains 2 bits for representing the supported number of physical processors on the bus. These two bits are MSB aligned where 00b equates to singleprocessor operation, 01b is a dual-processor operation, and 11b represents multiprocessor operation. The Intel® Xeon® Processor 7200 Series and 7300 Series is an MP processor. The remaining six bits in this field are reserved for the future use. Writes to this register have no effect. Example: An MP processor will use C0h at offset 1Ch. 7.4.3.3.4 Offset: 1Ch Bit Description 7:6 Multiprocessor Support UP, DP or MP indictor 00b: UP 01b: DP 10b: Reserved 11b: MP 5:0 RESERVED 000000b-111111b: Reserved MCF: Maximum Core Frequency This location contains the maximum core frequency for the processor. Format of this field is in MHz, rounded to a whole number, and encoded in hex format. Writes to this register have no effect. Example: A 2.666 GHz processor will have a value of 0A6Ah, which equates to 2666 decimal. 7.4.3.3.5 Offset: 1Dh-1Eh Bit 15:0 Maximum Core Frequency 0000h-FFFFh: MHz Description MAXVID: Maximum Core VID This location contains the maximum Core VID (Voltage Identification) voltage that may be requested via the VID pins. This field, rounded to the next thousandth, is in mV and is reflected in hex. Writes to this register have no effect. Example: A voltage of 1.350 V maximum core VID would contain 0546h (1350 decimal) in Offset 1F - 20h. Offset: 1Fh-20h Bit 15:0 Maximum Core VID 0000h-FFFFh: mV Description 128 Document Number: 318080-002
