Asus announces recall program for its Z690 Maximus Hero motherboards


Just before Christmas, reports of failures and buried components on Asus ROG Maximus Z690 Hero motherboards started to emerge. Normally, one or two isolated incidents should not be alarming, but in the days that followed, more reports were published. After some investigation, Asus started preparations for a recall and replacement program, so if you’re using any of these popular cards, you might want to shut it down and look for a replacement.

Users took to social media and the Asus ROG Forum to share their experiences. One user, maximumrog57, went into details with pictures, a few of which we have included in this article.

The user reported that his card would not publish completely, with a BIOS zip code of 53, which signifies a RAM issue. An inspection revealed burnt components adjacent to the memory locations, which would indeed explain the failure of the memory subsystem. Other users have reported similar experiences with audible pops, electronic burning odors, and system shutdowns.

Well-known youtuber Buildzoid from Actually Hardcore Overclocking did some research and reported that a specific capacitor on the Z690 Hero was improperly installed. Asus has since confirmed that this is the case and will offer replacements.

We are delighted to see Asus act quickly on this issue. If you have a card from one of the affected bundles, it’s good to know you’re covered before you have a problem. Buildzoid also deserves credit for its investigation (and confirmation). We reviewed G.Skill’s Trident Z5 DDR5-6000 memory and also used Team Delta DDR5-6400 and found no issues when testing on the Asus Maximus Z690 Apex. Of course, the Apex features a very different VRM memory design, so it’s no surprise. We hope this was an isolated manufacturing issue. Hopefully users will get their replacements and everything will be in the rearview mirror soon.
