459 DDR3-1333 Configurations with Three DIMMs per Channel May

Experience Unreliable Operation

Description

In systems with three DDR3-1333 registered DIMMs on a channel, the processor memory subsystem

may exhibit unreliable operation over the allowable voltage ranges.

Potential Effect on System

Memory system failure, leading to DRAM ECC machine check errors.

Suggested Workaround

In a configuration where three registered DDR3-1333 DIMMs are populated on one channel, BIOS

should de-rate DDR3-1333 system memory to 533 MHz operation (DDR3-1066) by setting the

DRAM Configuration High Register[MemClkFreq] (F2x[1, 0]94[2:0]) to 100b and adjusting

memory subsystem timing parameters accordingly.
