ASUS to recall ROG Maximus Z690 Hero motherboards

The company will work with government agencies to begin the recall process of the motherboards affected by the design flaw. 

Buildzoid was right. ASUS has now officially confirmed that some Z690 Hero motherboards have indeed an incorrectly installed capacitor around the memory. This is why some users might see a mysterious 53 debug code which means that the memory is not being detected. This wouldn’t be a huge problem as the warranty covers such issues, but in extreme cases, Hero motherboards would actually start to catch fire.

Interestingly, the YouTuber managed to find determine the reason for the Z690 Hero problems simply by looking at the pictures shared by users and by comparing them to working samples.

Those findings have now been confirmed by ASUS, who published an official statement over at their Facebook account. Users are asked to verify if their motherboards are affected by the production flaw by comparing their product code. The company will work with government agencies to start a replacement program.
