The DP4400 may report a missing or faulty DIMM (Dual Inline Memory Module) during boot.
Uncorrectable memory errors may also be reported on the affected slot/DIMM.
Example of Errors seen during Boot:
UEFI0339: The Dual Inline Memory Module (DIMM) in the memory slot <XX> is disabled because of initialization errors caused by uncorrectable memory errors, invalid configuration and others.
UEFI0058: Uncorrectable Memory Error has occurred because a Dual Inline Memory Module (DIMM) is not functioning.
During the power cycle of the underlying Hardware platform, the system performs a Power on Self Test (POST).
When power is turned on, POST is the diagnostic testing sequence that a computer's basic input/output system (BIOS) runs to determine if the computer keyboard, random access memory (RAM i.e. DIMM's), disk drives and other hardware are working correctly.
An error found in the POST is usually fatal and will halt the boot process, since the hardware checked is absolutely essential for the computer's functions.
Possible faults related to DIMM errors are:
Suitably qualified personnel may attempt the following:
Please contact Dell-EMC Tech Support to report this issue & Field Engineer will be dispatched to test or replace the faulty DIMM, if needed.
DP4400 expected Memory Slot pairs are as follows:
