You could try memtest86 (which is much more thorough -- it's a mini-OS of its own that needs to be booted). I would certainly not be surprised if it's thermal in nature. If you are using OpenCL, I wouldn't be surprised if it's the video card if it's the only intensive thing you do using it. But it could be the motherboard, it could be the CPU, it could be the memory. Is this a laptop or desktop? Particularly if it's a desktop, does it have a separate discrete graphics adapter (in a PCIe slot) or is it using the integrated graphics if your CPU has such? If it's a separate, discrete graphics adapter there's a fair-ish chance it could simply be the mechanical connector that's flaky. You can try removing the card and reseating it, or putting it in a different PCIe slot. You could try (carefully!) cleaning the contacts on the card with a pencil erasor -- just make sure that the card is grounded when you do this. If it has discrete graphics and is a laptop, it's probably not feasible to replace the graphics adapter. Higher-end laptops these days use what are called MXM modules (which are discrete cards), but they're not easy to remove and you need to be very careful putting things back together. If the laptop's under warranty, get it serviced that way; if not, you're probably better off buying a new laptop. If it's using integrated graphics (on either a laptop or desktop), the CPU could be bad (the integrated graphics is on the CPU chip). That's not that easy to test, because the graphics logic is connected to the CPU via an internal (to the die) PCIe link. -- Robert Krawitz <[email protected]> *** MIT Engineers A Proud Tradition http://mitathletics.com *** Member of the League for Programming Freedom -- http://ProgFree.org Project lead for Gutenprint -- http://gimp-print.sourceforge.net "Linux doesn't dictate how I work, I dictate how Linux works." --Eric Crampton ____________________________________________________________________________ darktable user mailing list to unsubscribe send a mail to [email protected]
