Hiji, by the way, I did not find a model called A7N266VX on Asus website. So I clicked the most similar model which is A7N266VM. And there I found that a couple of updates were made to the BIOS and one of the updates before the last one was told to be imrpoving DDR module compatibility, which is what you're looking for.
This is the latest updated BIOS file :

And this is the DOS utility that uses the file above to update your BIOS :

But, attention. You must first make sure of the model since I already mentioned that I looked up in the most similar motherboard model to yours -not the exact one. Wrong BIOS file will irreversibly corrupt your BIOS, and so does the wrong updating. Be careful of what you are doing.
Good luck![]()
