Getting artifacts with Watercooled GPU.

[speedy0379]

HI all,
finally, after long hours of battling with WC setup last night, I finally got them to work without leaks.
anyways, I am having big trouble with Dangerden NV78 GFX block.
There is no leak from the GPU block or anything but when I boot the computer, I get artifacts all over the screen.
What would cause this problem?
Please help~~

I would remount the block and when you take it off look at the TIM imprinted on the block, if it looks like it wasn't making complete contact then that could be your problem.

It is also possible that you flexed the board during install breaking traces or a small cap...

Probably is just a ram chip getting hit from poor contact. Do as J-Mag says and take it off, checking the thermal compound impressions for good contact. If reinstalling it and/or using a little more compound doesn't fix it, return it to DangerDen and just get a Maze4 and some ramsinks.

Wow that was exact problem you pointed out J-Mag.
Thx J-Mag and cartmanea.
