You haven't updated your video card, still. Like I said, it is not the cause of problems, but it is for good measure and should be done.
It's not a dumb question by any means, but no, the errors have nothing to do with video or the GDDR (video ram.)
I would really make sure the NEC USB 3.0 driver is updated to latest too, as previously advised, although that is likely not a source of issues. Visit another motherboard on your manufacturer's site and download it from there. The latest is from either April or maybe even July.
It's a little difficult to tell you for certain, because these drivers have not been updated yet, which is slowing the progress of the analysis.
But what it all comes down to really, is likely defective memory like I've been saying a few times. Test the modules one at a time, in the slot closest to the CPU. See if errors are found like this.
