IBM PC Enhanced Memory Diagnostics
The IBM PC Enhanced Memory Diagnostics provide the capability to identify
a particular memory module (SIMM or DIMM) which fails during testing. Use
the System Board Layout section to reference the memory sockets, or select F1
twice to load the Online Manual and select Chapter 11, ″SIMM/DIMM/RIMM
Locator″.
Follow the steps below to locate the IBM PC Enhanced Memory Diagnostics
test options.
1. Select the DIAGNOSTICS option on the toolbar and press Enter.
2. Highlight either the Memory Test-Full or Memory Test-Quick option and
press Enter.
3. 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.
4. 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:
1. Either level of memory testing can be performed on all memory or a single
SIMM or DIMM socket.
2. Only sockets containing a SIMM or DIMM can be selected for testing.
Unpopulated sockets are noted by ........ beside the test description.
