Motherboard stuck on error code that stands for "CPU DXE Initialized" | Tom's Hardware Forum
February 16, 2012 - The DXE phase and Boot Device Selection (BDS) phases work together to establish consoles and attempt the booting of operating systems. The DXE phase is terminated when an operating system is successfully booted. The Dxe Core is composed of boot services code, so no code from the Dxe Core itself is allowed to persist into the OS runtime environment.

Do you have another cpu to test with?

DXE Errors? RIVE - Republic of Gamers Forum - 478602
March 6, 2024 - 4F: DXE IPL is started Ok, never heard of DXE... lets just restart and chalk to random weirdness. Restarts fine. Video card still messed up. I restart a couple more times just fine, and finally fix the video card issue by re-installing the drivers for it. Hoping that the new CPU will have fixed the random freeze thing I load up Prime95 and start it running... about 15-20m later computer shuts itself off and starts rebooting. However it again gets stuck on another error code...

r/techsupport on Reddit: Error codes 64 and 0E (CPU DXE initialization and Microcode not found) on p67 extreme4 gen3 with i5-2400. Is my cpu shot?
December 21, 2022 -

This computer has been running the same hardware for about forever as a workstation for my school 3D Design/printing club. Today, I came in and saw that both monitors were reading the BIOS splash screen with the error code 64 on the mobo. Swapped the ram around, got past 64 and now it hangs up on 0E which, by the manual, says that the microcode is not found. Anyone have an idea how to fix this?

  • Windows 7

  • i5-2400

  • 2x4Gb DDR3-1066

  • 3x250Gb 5400rpm

  • Asus DCU II R9 280

  • ASrock P67 Extreme4 Gen3

  • XFX Pro650w PSU

Edit: Magically went back to 64 aka CPU DXE initialization even with one stick of ram in any slot.

It is possible for an implementation to use events to log the status codes when the TPL level is reduced. ReportStatusCode() function can perform other implementation specific work, but that is not specified in the architecture document. In case of an error, the caller can specify the severity. In most cases, the entity that reports the error may not have a platform wide view and may not be able to accurately assess the impact of the error condition. The DXE driver that produces the Status Code Protocol, EFI_STATUS_CODE_PROTOCOL , is responsible for assessing the true severity level based on the reported severity and other information.

June 17, 2020 -

I just finished building my first pc (specs below) and when I went to POST for the first time, the mobo read the error code above. After researching, I was able to find a forum here suggesting that I might have either tightened down my water cooler too much or bent some pins on the cpu/mobo. After checking, it appears that the pins on the cpu/mobo are fine and I have also tried loosening the water cooling, but I’m still running into the issue.

In the POST checkpoint codes listed in this section, the first two digits are from port 81 and the last two digits are from port 80.

r/homelab on Reddit: Supermicro stuck on system initializing with POST error code DE
November 13, 2021 -

I bought a used supermicro board and I'm trying to use it, but so far no luck and it is stuck during POST. There is a number of google result about supermicro POST error codes and code manuals (like this one) but somehow I was able to find the one which has not been mentioned in any source: "DE". I've tried to change RAM sticks and slots but nothing has changed. Moreover, even without any RAM insterted the error is the same.

Has anyone encountered this before? Any ideas how to trouble-shoot this?

I used to have the same board. I recently upgraded to a ASUS Pro WS X570-ACE and a Ryzen 5950X. I gave the CPU, memory, heatsink, and motherboard to my father. You need to give a lot more detail. What processor? Example: Intel Xeon E5-1620 v3 3.5GHz Is the processor known good? What memory? brand? speed? number of sticks? Registered? Unregistered? ECC? Is the memory known good? Motherboard beeps? There is a built-in PC speaker. So you should hear some beeps. Bent socket pins? CPU oriented and seated properly? Where did you buy the motherboard? Reddit? Local? Amazon? eBay? Friend? Does the post code change if you remove the CPU? From some googling it is likely problems: DXE error, which basically means CPU/chipset/motherboard initialization problem The microcode isn't up to date enough for your processor, aka you need a bios update before you can use the processor you are trying to use. You can likely upgrade the bios through IPMI. I say this, because I once misflashed the bios from Linux. I used IPMI to reflash it and recover the board. You might also be able to get more useful information out of IPMI. Link to manual to help with using IPMI: https://www.supermicro.com/manuals/motherboard/C612/MNL-1643.pdf If it is the microcode and you can't update through IPMI, then you will need another compatible processor to flash the bios. Other ideas: Try a different processor Try a different power supply Try one memory stick in the left most memory slot when the motherboard is oriented with the rear I/O to the left. Try different memory Disconnect everything but CPU, memory, and power from the motherboard. This includes front panel connectors, and rear i/o including video/keyboard/mouse. Just short the power button pins with a screwdriver. Be sure to connect the 8pin connector for the CPU at the top of the motherboard. Do a CMOS clear Post recovery ideas: https://old.reddit.com/r/DataHoarder/comments/6hgdxv/72tb_of_new_storage_merged_with_36tb_of_existing/
