Intel® Server System SC5650HCBRP TPS
Upper nibble bits = 1110b = Eh; Lower nibble bits = 1101b = Dh; the two are
concatenated as EDh. Find the meaning of POST Code EDh in below table – Memory
Population Error: RDIMMs and UDIMMs cannot be mixed in the system.
Progress Code Progress Code Definition
Multi-use Code
This POST Code is used in different contexts
Seen at the start of Memory Reference Code (MRC)
Start of the very early platform initialization code
0xF2
Very late in POST, it is the signal that the OS has switched to virtual memory mode
Memory Error Codes (Accompanied by a beep code)
These codes are used in early POST by Memory Reference Code. Later in POST these same codes are used for other Progress Codes.
These progress codes are subject to change as per Memory Reference Code
0xE8 No Usable Memory Error: No memory in the system, or SPD bad so no memory could be detected, or
all memory failed Hardware BIST. System is halted.
0xEB Memory Test Error: One or memory DIMMs/Channels failed Hardware BIST, but usable memory
remains. System continues POST.
0xED Population Error: RDIMMs and UDIMMs cannot be mixed in the system.
0xEE Mismatch Error: more than 2 Quad Ranked DIMMS in a channel.
