RES3: Reserved 3
These locations are reserved. Writes to this register have no effect.
7.4.3.4.2
L2SIZE: L2 Cache Size
This location contains the size of the level two cache in kilobytes. Writes to this register
have no effect.
Example: The Intel
®
Xeon
®
Processor 7200 Series and 7300 Series has a 2x4MB
(8192 KB) L2 cache total. Thus, offset 27 - 28h would contain 2000h.
7.4.3.4.3
L3SIZE: L3 Cache Size
This location contains the size of the level three cache in kilobytes. Writes to this
register have no effect.
Example: The Intel
®
Xeon
®
Processor 7200 Series and 7300 Series has no L3 cache.
Thus, offset 29 - 2Ah will contain 0000h (0 decimal).
7.4.3.4.4
MAXCVID: Maximum Cache VID
This location contains the maximum Cache VID (Voltage Identification) voltage that
may be requested via the CVID pins. This field, rounded to the next thousandth, is in
mV and is reflected in hex. Writes to this register have no effect.
Example: The Intel
®
Xeon
®
Processor 7200 Series and 7300 Series does not utilize a
Cache VID. Offset 2B - 2Ch will contain 0000h (0 decimal).
