Memories Cannot Be Fully Detected

Publication Date:  2015-07-30 Views:  19 Downloads:  0
Issue Description
The memory capacity detected during Basic Input/Output System (BIOS) boot is less than the actual memory capacity.

NOTE:
When the system is being started, press and hold down F2 to enter the BIOS to check the value of Total Memory in the BIOS.


Handling Process
Cause 1: The memory module is not installed in the proper slot.

1.  Before checking, execute the shutdown command to power off the device and then disconnect the device from the power socket and other devices.

2.  Open the top cover of the HDP3500E main control board enclosure.

     For details, see Opening a Main Control Board Enclosure Top Cover in Replacing a Fan Module.

3.  According to the information in Table 1, check whether the memory module is installed in the proper slot. The memory slot on the mainboard is shown in the red box of Figure 2.

Table 1 Memory configuration and installation 

  • If the memory module is not installed in the proper slot, fix it to the right slot.
     
  • If the memory module is installed in the correct slot, go to cause 2.
4.  After reinstall the memory module, start the device, detect the memory capacity in BIOS.
  • If the detected capacity value is equal to the actual memory capacity, the fault is rectified.
  • If the fault persists, go to cause 2.
Cause 2: The memory module is faulty.

1.  Replace all old memory modules with new ones. After the replacement:
  • If none of new memory modules can be discovered in the BIOS, go to cause 3.
  • If all new memories can be detected in BIOS, replace a new memory module using the memory module previously removed and check whether this memory module can be detected. Replace the old memory modules in the same way to determine which memory modules are faulty.
2.  Replacing the faulty memory module:
  • If the memory capacity detected in BIOS is the same as the actual memory capacity, the fault is rectified.
  • If the fault persists, go to cause 3.
Cause 3: The memory slot is faulty.

Replace the chassis.
  • If the detected capacity value is equal to the actual memory capacity, the fault is rectified.
  • If the fault persists, contact the technical support engineers of your vendor.
