ROG Maximus Z690 Hero: Asus confirms assembly errors and withdraws mainboards

Asus recalls selected ROG Maximus Z690 Hero motherboards for Intel Alder Lake (trial). The manufacturer confirms that the affected circuit boards will fail as a result of incorrectly dissolved capacitor. Reports of defective mainboards have so far only come from North America.

One suspicion is certain

A few days ago, the first users of the ROG Maximus Z690 Hero came up with error reports. If you specify the error code “53” (memory is not installed), your system can no longer boot. Overheated MOSFETs were found near the debug code display on the affected boards, but not all of them.

YouTube Builtside When comparing photos published by affected customers, it became clear that all defective circuit boards (including those without obvious defects) had one thing in common compared to the previous defective ones: polarized capacitors, which were soldered directly to the MOSFETs, were fitted. In exactly the opposite direction. Buildzoid suspected that this was the reason for the failures.

On Facebook Asus has now confirmed: Incorrect installation of the capacitor in the power supply of the memory on the output line is causing the problem.

In our current investigation, we have detected in advance a potential reverse memory capacitor problem in the manufacturing process, which can result in error code 53, no entry or one of the output lines causing damage to the motherboard components.

These products are vulnerable

Asus has detected infected motherboards. You need to add the area number 0MB18E0-MVAAY0 And serial number starting with MA, MB or MC. Both information can be found in the main board box and not on the circuit board. Owners of such boards are requested to contact Asus Support.
