I have a gtx titan x with some broken vram. I know it is possible to boot using a certain part of vram to check which part is broken, but I can't find it anywhere.
Do any of you know how I could first test which part of the vram is broken and secondly exclude that from being used?
I'm fairly new so bare with me.
Thanks in advance

I never heard of this kind of thing. You should check Nvidia's documentation for their Linux driver. It seemed to me the documentation shows everything the driver can do so if there's a setting to exclude GPU memory areas it hopefully lists it.
The Nvidia documentation is installed in "/usr/share/doc/nvidia/html/". Open the "index.html" file from that location in your browser.
Nvidia have forums for their Linux driver. You could ask there if someone knows an undocumented setting to exclude vram areas. You can find the Nvidia Linux forum here:

Something I just remembered: I had a GTX 680 4GB that was used for compute and started failing after two years or so. That card could be made to run stable by using the overclocking features to reduce its clock speeds. The card then continued to work well for another two years or so. Maybe try the same and see if your card runs stable when you reduce core or memory speeds.

I'll try that, how did you over \ underclock it?
