Hello,

I've been trying to debug an issue with the ROMED8-2T motherboard with the EPYC 7113 CPU.

When I boot, the LCD screen on the motherboard (dr debug) says d0 - meaning "DXE_CPU_ERROR" according to manual.

Here's what I've tried so far to fix this:

- A different model of RAM from a different supplier

- Upgraded Bios to 3.80 (this was the default on the motherboard)

- Cleared CMOS

- In addition to the 8-pin CPU plug, also occupied the 4pin CPU plug (Tried the split 4 pin plugs, 8 pin plugs for that slot, etc.)

- Upgraded Bios to 3.20 via the web interface (IPMI) [Needed according to site for compatibility with 7113]

- Seat 1 stick of ram in slot C1 [Where the manual says to put the ram for 1 slot mode]

- reseat the CPU

- reseat the RAM

- Tried different RAM sticks

*Something I suspect*:

- I don't have the 4-Pin plug plugged in for the CPU, and I know the 7113 is a high TDP CPU. Could this be why it's failing to boot? *Are you supposed to plug in the 4-Pin connector for the EPYC 7113?*

One thing I'll also add: When I boot without the stick of ram in, it says 10 on Dr debug. I've tried 3 different sticks of ram, but I ordered a different type of ram just in case.

Note: This CPU is genuine/official, NOT an engineering sample / ES.

I am using officially supported HMAA8GR7AJR4N-XN SK HYNIX 64GB memory modules.

Does anyone who anything else I can troubleshoot here?

Thank you everyone, any help is extremely appreciated.

UPDATE: tried occupying 4-pin from my rm1000x PSU but still no luck.

UPDATE 2: Tried a different model of RAM from a different retailer (supported by Mono), same error.

Update 3: Turned out to be the CPU. I replaced it with a similar CPU in the same generation (EPYC 7282) and it's working fine now.

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.

CPU: AMD Threadripper 3960X 3.8 GHz 24-Core Processor CPU Cooler: Thermaltake Water 3.0 Riing RGB 360 40.6 CFM Liquid CPU Cooler Motherboard: ASRock TRX40 TAICHI ATX sTRX4 Motherboard Memory: G.Skill Trident Z RGB 128 GB (4 x 32 GB) DDR4-3600 CL18 Memory Storage: Samsung 970 Evo 1 TB M.2-2280 NVME Solid State Drive Storage: Intel 660p Series 2.048 TB M.2-2280 NVME Solid State Drive Storage: Seagate IronWolf Pro 16 TB 3.5" 7200RPM Internal Hard Drive Video Card: Asus GeForce RTX 2080 SUPER 8 GB DUAL EVO OC Video Card Case: NZXT H710i ATX Mid Tower Case Power Supply: Corsair HX Platinum 1000 W 80+ Platinum Certified Fully Modular ATX Power Supply Operating System: Microsoft Windows 10 Home OEM 64-bit

Im a little stumped on the issue my PC is presenting me. Booted my PC up this morning but got into Windows and everything took ages to actually show up. I went to reboot it and it just hangs at the POST with code 64 which is the CPU DXE initialisation. It eventually, maybe after about a minute or 2 it finally boots but takes absolutely ages to boot into windows but from there the PC is fine apart of having to load windows specific applications, sometimes they work but other times they stop responding or take ages to load.

Booting the PC up from a full shutdown state presents no issue other than a slow boot.

Is this a sign of a failing CPU or another issue, maybe with BIOS?

Where to begin… I guess a little back story would help.

This build of mine was made back in 2014 and has lasted me until now. The last thing was in the beginning of last year upgrading my GPU and it’s been working fine. Never had an issue like this before and it was running smoothly until one day recently it just… won’t… post. Everything turns on (as in the cooler, case fans, gpu and hdd, ect) EXCEPT the monitor. Mind you the monitor does receive power and connected to the computer.

I guess now is a good time as ever to give my pc specs:

Mobo: Asus Z97 Pro Wifi AC CPU: Intel i7 4770K RAM: 4x Corsair Vengeance (32 GB) PSU: Corsair AX760i GPU: AORUS GeForce RTX™ 2060 XTREME 6G (rev. 2.0)

Now that that’s out of the way, I look at my motherboard and see that the q-code says 63 which in the manual book says it means: CPU DXE Initialization is started and the light that always stays on is the VGA led.

I search everywhere on google and even here on reddit and I’ve tried several different approaches for instance:

1. Disconnecting GPU and use the onboard DisplayPort. (Did not work)

2. Changing the DisplayPort cable. (Did not work)

3. Booting with one stick of RAM. (Did not work)

4. Booting with one stick of RAM and testing it in all slots. (Did not work)

5. Booting with 2 sticks of RAM (in Dual Channel mode). (Did not work)

6. Tried bios flashback. (Did not work)

7. Tried using another set of known-working RAM (Did not work)

8. Tried Clearing CMOS by jumper (Did not work)

9. Tried Clearing CMOS by removing battery (Did not work)

10. Tried removing motherboard from case and powering it up outside of the case. (Did not work)

I don’t have another motherboard to rule out the CPU or another CPU to rule out the motherboard.

I’ve been attempting this repair for about a month now. I have a video that shows what always happens when I turn on the computer.

Any ideas what it could be? Any help is appreciated.

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.
