Software for testing VRAM

[Roman78]

I would like to know if such software exist for PPC.

I have divers Software for Intel X86 computers, but also want to test VRAM of older macs. The reason is, I'm getting an iMac for repair which has a graphical problem. OSX works fine but 3D would fail. The screenshots i saw would suggest VRAM error, but before replacing the VRAM i would like to make a simple test, like memtest86 for RAM.

Apple hardware test will test the VRAM. I don't know how extensively it does it, but it definitely does it. I was having a bad graphic glitch on a 9800 Pro, booted up an AHT CD and it failed while testing the VRAM.
