I know what you want - to disable the bad memory. There is not an easy way to do that - try underclocking the memory first to see if it work OK.

我知道你想要什么 - 禁用坏记忆。没有一个简单的方法可以做到这一点 - 先尝试对内存进行降频，看看它是否正常工作我是我

Blurred? or Static-y/Colorful pixel-y?

I've only EVER seen 'blurred' output on analog outputs. Either poor quality DACs, or poor cables, or interferance from being ran alongside AC power cables.

However, I also have a 280X 3GB, w/ bad RAM. It its case, It gets artifacts and crashes, even underclocked.

模糊？还是 Static-y/Colorful pixel-y？

我只见过模拟输出上的“模糊”输出。DAC质量差，电缆质量差，或者与交流电源线一起运行的干扰。

但是，我还有一个 280X 3GB，带坏 RAM。就其情况而言，它会出现伪影和崩溃，甚至降频。

Okay... translation issues. Yes, that's typically bad VRAM.

Refer to Video Card repair-ers on YouTube, etc. for IDing bad VRAM chips. I am unsure how to 'lock out' that bad VRAM; first step, regardless.
I do not know the tools used but, have seen such tools used to directly ID bad VRAM.

Uncertain if there were any 1.5GB versions of the card that used half the (same) VRAM; as that would be the start to my route, in your position. (7870XT 2GB Cross flash?)
