Ω pull-up to
VCCP
Point-to-point connection to ICH4-
M, with resistor placed by the
processor.
RESET#
51
Ω pull-up to
VCCP
If ITP700FLEX is Used: RESET#
connects from processor to GMCH
and then forks out to ITP700
FLEX, with pull-up and series
damping resistor placed next to
ITP. Second pull-up may be
required at ITP if there is noise
issues on the signal.
SLP# Point-to-point connection to ICH4-
M.
SMI# Point-to-point connection to ICH4-
M.
STPCLK# Point-to-point connection to ICH4-
M.

Ω pull up to
VCCP
THERMTRIP#
56
Ω pull-up to
VCCP
Point-to-point connection to ICH4-
M, with resistor placed by ICH4-M.
THERMTRIP# is a VCCP signal. If
connecting to other device,
voltage translation logic may be
required.
VCC[85:0] Connect to VCCP
VCCA, VSSA,
VCCIOPLL
Connect to VCCP
via filter

VCCSENSE,
VSSSENSE
Connect to test vias
VSS[182:0] Connect to gnd
NOTE: Default tolerance for resistors is ± 5% unless otherwise specified.
