IBM PC730/PC750 - False level 2 cache error with QaPlus/Pro
Applicable to: World-Wide
Service Information:
The level 2 cache test in QAPlus/Pro version 5.43 and lower may indicate a level 2 cache test failure when the cache is tested in loop mode with Advanced Power Management (APM) enabled. This failure occurs on IBM PC 700 Series 6877 or 6887 with EDO (Enhanced Data Output) memory SIMMs and a 133Mhz or 166Mhz Pentium Processor installed. The cache size may be either 256Kb or 512Kb.
When the level 2 external cache is tested in loop mode with a setting of 112 or higher, a test failure may be indicated at the end of the 112th loop of the test. Disabling APM allows the test to run properly to completion.
This is a false indication. The external level 2 cache should NOT be replaced. This problem will be resolved in future revisions of QAPlus/Pro.
