标题: 盈通RX800XL花屏故障
如题，现象是时花时不花，因为没有可用测试软件，初步测试：GPU供电1.43，显存供电2.09V（有点高），显存供电由RT9214和两个MOS管组成，从RT9214的PDF资料上看到可以改变6脚上的电阻，调节输出电压，但实际电路板上找不到那两个电阻，请版主帮帮忙吧

本版就有软件下载，先测试后再说，电压在正常范围内

下了R3 V1.12的测，刚开始测的时候不花，等测到最后就会黑了，重启后，什么都看不到，花得更严重了，关机几分钟后再开，不花了，进WIN PE也没有问题，再测，还是花了，放了一下又好了，什么回事呵？

R3测试结果如下：

这个很明显应该是GPU有虚焊了。
重新加焊GPU。然后搞好散热。

GPU空焊了
