Troubleshooting memory DIMMs
About this task
Follow the steps below to troubleshoot a DL360p G8 SRVR 4 GB Memory RDIMM.
Procedure
1. If general memory problems are occurring:
a. Check system insight display for any memory error LEDs.
b. Isolate and minimize the memory configuration.
c. Check any server LEDs that correspond to memory slots.
d. View power-up screen for any memory errors displayed if monitor is installed.
e. If you are unsure which DIMM has failed, test each bank of DIMMs by removing all
other DIMMs. Then, isolate the failed DIMM by switching each DIMM in a bank with a
known working DIMM. Start installing CH1A first and then proceed to install CH2B,
second and continue to populate in that order.
f. Remove any third – party memory.
g. To test the memory, run HP Insight Diagnostics (Troubleshooting Guide Volume 1, pg
68). A keyboard and mouse are required.
2. If the server is out of memory:
a. Be sure no operating system errors are indicated.
b. Be sure a memory count error did not occur. Refer to the message displaying memory
count during POST. This can only be viewed with monitor and keyboard.
3. If a memory count error exists, a possible cause is that the memory modules are not
installed correctly.
a. Be sure the memory modules are supported by the server.
b. Be sure the memory modules have been installed correctly in a supported configuration.
c. Be sure the memory modules are seated properly
d. Be sure no operating system errors are indicated.
