GTX Titan Black memory errors

Vote count:

I'm remotely running code on a GTX Titan Black and getting memory errors or outright crash+reboots despite there always being ample memory left.

I get 3 kinds of errors on different alterations of my code (the alteration being whether to load small or large batches of images on the GPU at each iteration):

- cuda runtime error : an illegal memory access was encountered

- cuda runtime error : out of memory

- shell freezes, impossible to ssh onto it for a few mins, so I assume GPU crashes and system reboots.

Is this a generic problem that other have run into? I'm aware it might be specific to my code since error varies on how I implement it, but maybe these unjustified memory errors also point to sys admin or driver restrictions?
