IMON Slope
IMON (Load Current Monitor) Slope is defined in 1/100 increments
and uses the BIOS VR mailbox command 0x4. Range is 0-200. For
example, enter 125 for a 1.25 slope. Enter 0 for AUTO.
IMON Offset
IMON Offset is defined in 1/1000 increments and uses the BIOS VR
mailbox command 0x4. For example, enter 25,348 for a 25.348 offset.
Range is 0-63999.
IMON Prefix
This feature sets the IMON offset value to a positive or negative num-
ber. The options are + and -.
VR Current Limit
This feature sets the Voltage Regulator current limit. The value repre-
sents the maximum instantaneous current allowed at any given time.
The value is represented in 1/4A (Ampere) increments. A value of 400
equals 100A. Set this number to 0 for Auto. This uses the BIOS VR
mailbox command 0x6.
VR Voltage Limit
This feature sets the Voltage Regulator voltage limit. The value is
represented in mV. A value of 1250 equals 1.25V. Set this number to
0 for Auto. This uses the BIOS VR mailbox command 0x6.
TDC Enable
Enable or Disables TDC (Thermal Design Current). The options are
Enabled and Disabled.
TDC Current Limit
The TDC Current Limit is defined in 1/8A (Amperes) increments and
uses the BIOS mailbox command 0x1A. A value of 1000 equals 125A.
Range is 0-32767. Enter 0 for 0 Amps.
TDC Time Window
The TDC Time Window is defined in milliseconds. Range is 1-8ms and
10ms. Note that 9ms has no valid encoding in the MSR definition. The
options are 1ms, 2ms, 3ms, 4ms, 5ms, 6ms, 7ms, 8ms and 10ms.
