Question:

How can I fix the green boot debug light and no display issue after removing one of the RAM sticks?

I have a dual-channel RAM setup with two sticks of 8GB each. When both sticks are installed, I get the DRAM and CPU LED indicators on the motherboard. The GPU, CPU cooler, and RAM lights are on and the fans are spinning, but there is no display on the monitor. I have tried resetting the CMOS and reseating the RAM, but nothing changed. What other steps can I take to troubleshoot this problem?

Answer:

If you are experiencing a green boot debug light and no display issue after removing one of the RAM sticks from your dual-channel setup, you might be dealing with a compatibility or configuration problem. Here are some possible solutions that you can try to fix this issue.

Check the RAM compatibility

The first thing you should do is to check if the RAM sticks are compatible with your motherboard and each other. You can refer to the motherboard manual or the manufacturer’s website to find out the supported RAM specifications, such as speed, voltage, timing, and capacity. You should also make sure that the RAM sticks are from the same brand, model, and batch, as mixing different RAM sticks can cause instability or incompatibility issues.

Check the RAM configuration

The next thing you should do is to check if the RAM sticks are configured correctly in the BIOS. You can access the BIOS by pressing the Del or F2 key during the boot process. Once in the BIOS, you should look for the memory settings and make sure that they match the RAM specifications. You should also enable the XMP or DOCP profile, which is a preset configuration that optimizes the RAM performance. If you are not sure how to do this, you can consult the motherboard manual or the RAM manufacturer’s website for guidance.

Check the RAM slots

The last thing you should do is to check if the RAM sticks are inserted into the correct slots on the motherboard. Depending on your motherboard model, you might have two, four, or more RAM slots, which are usually color-coded or numbered. For a dual-channel setup, you should install the RAM sticks into the same color or number slots, such as A1 and B1, or A2 and B2. You should also make sure that the RAM sticks are fully seated and locked into place. You can refer to the motherboard manual or the online tutorials for more details on how to install the RAM correctly.

Conclusion

By following these steps, you should be able to fix the green boot debug light and no display issue after removing one of the RAM sticks. If the issue persists, you might have a faulty RAM stick, a faulty motherboard, or a faulty power supply. You can try to test each component individually or use a different system to isolate the problem. You can also contact the technical support of your motherboard or RAM manufacturer for further assistance. We hope this article was helpful and informative. Thank you for reading.
