Compensation

A system memory compensation resistor (SRCOMP) is used by the GMCH to adjust the buffer
characteristics to specific board and operating environment characteristics. Refer to the Intel
Chipset Family: 82815 Graphics and Memory Controller Hub (GMCH) for use with the Universal
Socket 370 Datasheet for details on compensation. Tie the SRCOMP pin of the GMCH to
40 1% or 2% pull-up resistor to 3.3 Vsus (3.3Volt standby) via a 10-mil-wide, 0.5 inch trace
(targeted for a nominal impedance of 40
