IBM Advanced Memory Diagnostics The IBM Advanced Memory Diagnostics provide the capability to identify a particular memory module (SIMM/DIMM) which fails during testing. Use the System Board Layouts section in the latest PC 300/700, IntelliStation Hardware Maintenance Manual (HMM) to reference the memory sockets, or select F1 twice to load the Online Manual and select Chapter 11 'SIMM/DIMM Locator'.

Memory Test-Full The full memory test will take about 80 seconds per MB of memory and will detect marginal, intermittent, and solid (stuck) memory failures. Memory Test-Quick The quick memory test will take about 20 seconds per MB of memory and will detect solid (stuck) memory failures only. Notes Either level of memory testing can be performed on all memory or a single SIMM/DIMM socket. Only sockets containing a SIMM or DIMM can be selected for testing. Unpopulated sockets are noted by ........ besides the test description. Reference Information 207
