我自己试了一下关闭通道的命令
前提条件:1 需要mods版本在400.179。367的版本没有-floorsweep的参数。
2 需要双显卡,不能对当前连接显示器的显卡做关闭通道。我接了2张显卡,一张gtx 950,一张gtx 1070,。显示器接上950,要关闭1070的D通道
命令如下:
mods gputest.js -short -floorsweep fbio_disable:0x08:fbp_disable:0x08 -run_on_error执行完毕后,屏幕会黑,过一会按alt-ctrl-del重启电脑,进入mods所在的目录查看mods.log
输出结果如下:

关闭D通道之后就正常了,说明D通道的显存有问题。
关闭A/B/C/D通道的命令,可以看到区别就是数字不同
关闭A通道: -floorsweep fbio_disable:0x01:fbp_disable:0x01
关闭B通道: -floorsweep fbio_disable:0x02:fbp_disable:0x02
关闭C通道: -floorsweep fbio_disable:0x04:fbp_disable:0x04
