Product Errata 77
Revision Guide for AMD Family 10h Processors

328 BIST May Report Failures on Initial Powerup
Description
When BIST is run after initial powerup, a non-zero (i.e., failing) value may be erroneously reported in
EAX.
Subsequent BIST runs (induced by warm resets) are not affected by this erratum, and accurately
report pass/fail as determined by the presence or absence of detectable defects in the structures tested.
Potential Effect on System
The processor may incorrectly represent itself as being defective on initial powerup. The system
response to this is system software dependent.
Suggested Workaround
On initial powerup, system software should disregard the BIST result in EAX.
Fix Planned
Yes
