1) Reseat Your Memory
If you’ve just built your PC, it’s possible that your RAM isn’t in proper contact with the motherboard. To fix this issue, attempt to reseat the RAM sticks, which simply means to remove and then properly insert the memory again.
2) Disable XMP
XMP enables memory to run at higher than JEDEC specifications, which is essentially a form of overclocking. This can introduce instability, and disabling XMP can fix any memory issues you’re facing. The option is literally a few clicks away from you.
3) AM5 Specific “Memory Training” POST Error
If you have a new AM5 build and you’re facing the same RAM issue, it may be that your memory is still in its “memory training” phase. As silly as it may sound, your system’s memory controller needs to learn the various parameters of the DDR5 kit used to ensure stable operation.
4) Remove the CMOS Battery / Reset BIOS
Resetting the BIOS by removing the CMOS battery can resolve DRAM issues. To reset your BIOS, follow these steps:
5) Update Your BIOS
We are gradually approaching the more complex steps, and one of them is to update your BIOS. Board manufacturers often release newer BIOS revisions that improve RAM compatibility and stability. Updating your BIOS can be both easy and difficult, depending on how recent your motherboard is. Modern motherboards have the option for BIOS flashback, which allows you to update your BIOS without entering the system. Get a working PC and download the required BIOS revision. After renaming the BIOS properly, store it inside a USB Flash Drive and enter the BIOS to, well, update your BIOS.
6) Faulty Memory
If none of the steps worked for you so far, we’re entering into the realm of uncertainty—and possible hardware failure. Memory is quite resilient; however, being electronic, it too shall fail someday. An easy way to verify if your memory is faulty or not is to borrow a working memory kit from a friend or fellow. You may also try individual DIMMs as explained in the reseating method above. If 1 DIMM works and the other doesn’t, you have a faulty memory kit. If both don’t work, the next step is to get access to a working kit. Now try the working memory modules and check to see if the error persists. If, for some reason, you still get the same issue, even with a working kit, there are 3 possible culprits then.
7) Dead CPU, PSU, or Motherboard
Assuming you’ve tried out a working memory kit with your PC and you still see that annoying DRAM light, the issue might be with your other components. Let’s start with the easiest to replace, your PSU.
↪ Power Supply Unit
It is very much possible that your PSU got damaged due to excessive voltage/current and is unable to supply ample power to the memory. Try another Power Supply or use your current supply in another PC.
↪ CPU
Next up is the CPU. If you have access to a processor supported by your motherboard/socket, check to see if the system boots with that CPU. The CPU features memory controllers which are responsible for communicating with the RAM. In rare cases, this section of your CPU could be damaged, rendering it useless.
↪ Motherboard
The last resort is to swap all your components to a different motherboard. If your PC boots normally, you require a motherboard replacement. Again, as with the PSU, random voltage/current spikes or even ESD can severely damage the motherboard.
