ASUS RS500A-E12 DIMM Error
Some servers have reported Dimm slot Error, which a server assembly expert may conveniently resolve using specific troubleshooting procedures.
Steps to Follow
- Turn on the machine, Check the BIOS settings, and then reset to the default settings and restart.
- Access the IPMI and verify the BIOS and IPMI versions. If there are any recent versions available, flash the firmware and BIOS onto the recent versions.
- The majority of issues are able to handled by updating the BIOS and firmware, although some hardware-related troubleshooting may be required.
Hardware Troubleshooting Procedures
Unpack the Server and place it on a clean, shock-resistant surface.
Loosen the screws and remove the top cover by sliding .
Once you have access to the Server Components, check to see if the Memories are properly installed. If not, remove and reinstall the Memories.
Removing a Memory

Installing a Memory
After populating the Memories, restart the system and check the Bios and BMC Utilities to ensure the system is recognizing the Memories.
If the memories remain unrecognized, the CPU will be a cause for concern.
Remove all of the memory from the Slots, and then carefully remove the CPU Cooler by loosening the screws
Once you have gained access to the CPU socket, unscrew the screws and carefully remove the CPU from the rail Kit. To prevent damage to the CPU socket pins, place a CPU cap on the CPU socket before removing the CPU.
After removing the CPU, remove the socket cap and inspect the CPU socket for damage. If any CPU Pin damage is discovered, immediately report it to the vendor or the dealer for the motherboard replacement, or if you are able to clear the Pin damage, do so with the vendor's approval.

If no CPU damage is discovered, gently reinstall the CPU after cleaning the CPU surface.
Reinstall the CPU heat sink and memories, then close the top cover and secure it with screws.
Once the hardware re-alien task is complete, turn on the system and verify that the CPUs and memories are correctly identified by the system through IPMI or BIOS.
If the problem has not been fixed, contact the vendor or dealer for assistance.
