Code 0D???

[CheeChee]

So this is my situation:

Been using a 2080 super card for the pass 4 years, and everything seems to be running fine, until 2 days ago

Switch on my tower as usual, but now instead of usual start up, i was met with loud fan noise (seems coming from my graphic card) and no screen. Have to switch off power as the regular long press doesnt work

Tried couple of time, occasionally i manage to get into windows, but within a min or so, the loud fan noise comes back, and screen go blank.

I've unplug everything, did a thorough clean for dust etc, put that back together, and met with the same faith - loud noise from the fan, and wont go any further (system stuck at this stage until i switch off from the power)

Couple of hours later, with load on google search, taken all memory out, put them back in, unplug graphic card, plug it back in, and now i am at this following stage:

Computer start, the mini LED display run though bunch of code, and stop at OD, or 0D,(but graphic card fan seems running normal now)

Some say it is memory training error, some say it is CPU error...

Hence here i am, hoping anyone with better knowledge can help out, or point me towards the right direction into saving the system

Thank you!

Hi @CheeChee 
1. Clear CMOS

2. If no POST, insert one memory module in to slot A2

3. If no POST, reseat CPU cooler and CPU. Inspect CPU socket for any damage or debris

4. Remount CPU cooler and CPU whilst checking for consistent mounting pressure as per cooling vendor's instructions.

Morning!

Do i need to unplug lol cable before resetting it? Or is it ok to do it with cable in off? 

[Silent_Scone]

The AC should be off whilst working on the system.

[CheeChee]

Just clear the CMOS, and it seems to be back to 1 long beep, and 2 short beep….

shouldni continue with 1 ram stick at the time or?

Hello, @CheeChee 

Could you confirm your current BIOS version?
If it has not been updated to version 2601 released on August 30, 2023, please consider updating it, clearing CMOS, and then checking again.
Based on the description provided, one long and two short beeps may indicate a memory error during the boot process.
We suggest trying to install a single RAM module in the DIMM_A1 slot to see if the system boots.

Please also verify if the currently installed memory is listed in the ROG Zenith Extreme's QVL and if it is installed according to the recommendations on page 1-5 of the user manual.

Thank you.
