Dell Diagnostics DIMM Isolation
You can use the Dell Diagnostics software to identify a defective DIMM; however, if
you installed four DIMMs with the same density, the software cannot identify which
DIMM is defective.
To isolate the defective DIMM, perform the following steps:
1.
Remove two DIMMs in the same bank, BANK_1 or BANK_2.
2.
Run the Dell Diagnostics memory test.
•
For PowerEdge systems, run the memory test from a diagnostics diskette
created from the
Dell OpenManage Server Assistant
CD or from the utility
partition.
•
For PowerApp systems, run the memory test from the
Dell PowerApp
Resource
CD.
