微星官方回应：主板南桥裂缝问题和散热片螺丝有关

微星某型号主板的南桥芯片裂缝问题有结论了，微星日前终于作出回应。

微星表示：“少数 MAG Z790 Tomahawk WiFi 主板可能会遇到死机或无法正常开机的情况，确实和南桥有关系，我们已将有问题的主板妥善处理。经调查，南桥损坏和部分散热片压力螺丝有关，已采取积极措施来解决问题。”

另外，“改进后的芯片组散热片螺丝已开始大量量产，已知问题已得到解决。”

微星表示，如果您也是该主板，也遇到了情况的情况，可以联系渠道或卖家更换。不知道过保后，还能不能免费换，毕竟这是产品本身质量问题。

如果是其他型号主板，如果也遇到了无法开机，建议拆下南桥散热片看看，是不是有裂纹。

原文如下：

Regarding the MAG Z790 Tomahawk WiFi incident, we’ve discovered that a minority of units may encounter non-functional PCH potentially resulting in Dead on Arrival (DOA) of the motherboard product. We have isolated the cause to a previously used chipset heatsink screw design and have taken proactive measures to address this issue.

A revised chipset heatsink screw design has been implemented into our production, and the known cases have been resolved.

We uphold high standards of responsibility and accountability, and want to assure affected customers can promptly receive product replacements. Please contact our local customer service center for assistance.
