How did this pass MemTest? (infosec.pub)

Note the at least 3 literal errors on the pass screen...

Edit: Votes don't matter to me, but if you missed the three obvious errors on screen, you shouldn't be a technician. The problem was failed integrated GPU capacitors.

I believe, and I’m probably wrong here, so feel free to correct me, that the visual glitches are part of the video card’s implementation of this specific screen mode, which would be a graphics memory glitch. So the RAM might actually be fine, but you may have a bad video chipset instead.

You're both right and wrong. All cool.

The system's RAM was okay, but the system's VRAM was separate, but still integrated. It was the VRAM caps that were bad. After replacing those, the system worked fine.

Oh, nice! I was on the right track. :) Also, I think there’s another glitch. Shouldn’t there be a progress bar next to the 10%?
