Intel® 6400/6402 Advanced Memory Buffer Datasheet

Introduction

SMBus access to the AMB may be a requirement to boot a system. This provides a

mechanism to set link strength, frequency and other parameters needed to insure

robust operation given platform specific configurations. It is also required for diagnostic

support when the link is down.

The SMBus address straps located on the DIMM connector are used by the AMB to get

its unique ID.

More information is available in the SMBus chapter of this document.

Additionally, more detailed information about the SMBus, refer to the System

Management Bus (SMBus) Specification [HTTP://smbus.org/].
