94 Product Errata

41322 Rev. 3.84 August 2011

Revision Guide for AMD Family 10h Processors

360 DRAM CKE and Address Drive Strength Values May Be

Incorrect

Description

The processor does not correctly assign DRAM Output Driver Compensation Control

the specified assignments are shown in the following table; other assignments are not affected:

This erratum applies only when programming two different settings to the CkeDrvStren and

AddrCmdDrvStren register fields. Functionality is correct when the two register fields are

programmed to identical values.

Potential Effect on System

Pin drive strengths that differ from those expected may affect memory margins.

Suggested Workaround

No workaround required for system designers using AMD recommended values in these fields. With

the AMD recommended values, the erratum does not apply to any settings in 1T timing mode. A

workaround is not necessary in 2T timing mode as the impact of this erratum to overall memory

margins is minimal.

Fix Planned

Missing Assigned DRAM
