Hi thanks for the reply. The reason I am after a specific test is because, like nvidia cards, won't install drivers if you have a bad memory chip. No drivers. No gpuz. No information on anything. I assume ati cards will exhibit same issues. Also if the memory is corrupted it will cause a crash, even through internal graphics. The solution is to disable the card in safe mode. But then I am back to where I started. No information. And more importantly I need to identify which memory chip has failed so I can change one rather than all the memory chips, to save me the hassle of reballing them all.
Regards.
Matt.
Sorry to add to my previous post. Its not about these exact cards per say. I have a host of cards coming in for repairs and this is something I need to address on AMD cards. Thanks again
