Determining RAM issues on 820-3330

If RAM would be a problem the system typically locks up or crash and reboot. The cursor still being able to move is more likely to be a GPU issue. With these board that is hopeless as I believe the problem is inside the board vias.
Were any of these boards repaired/messed with?

Hey Duke, nope none of them show signs of repair at all. I thought it might be the GPU, but was optimistic when I saw the boards kept freezing during the first ~10 seconds of the RAM test on AHT. Any recommendation on what to do with the boards? I think we'll end up having damn near 20 of them...

edit: On that note; is there anything we can do to force these boards to crash if it is the GPU? Run FurMark for 10 hours or something? I want to recreate the failures for my own peace of mind.

Thanks, Duke. Would you be interested in having me send you a few of these weird GPU issue boards? I'm not sure if you've stopped trying to figure them out or not, but they'll be used for parts otherwise. Shoot me a message if so. A real shame, as we have so many. Thanks again!

GPU issue will manifest itself with either image issues or a kernel panic and reboot. A hard lockup is not common, the cursor can usually still be moved and caps lock light will still work and audio will keep running.

RAM issues will hard lock up the machine possibly resulting in kernel panic and a reboot.

Also try using DDRL PC12800 memory as some of them were originally equipped with that. In any case it will never hurt to use that.
