it really just seems like there is no logical explanation for it and it's kinda like a lottery, so check if you've won
in general i'd only trust hard facts, seeing how much shit is flinging around on p much everywhere this topic is brought up

My theory is the Card Bios hasn't been properly configured to reallocate power to the problem memory cores, causing the ram to choke, reallocate to the existing cores and then process a frame. Most motherboards do this sort of thing to the individual cores of the CPU but since NVIDIA is trying something new here by employing the same method to individual cores of memory, none of the other manufacturers are taking this into account.
I'm sure there will be a firmware/driver update that addresses this, but for the time being, if you can afford a 980 / 770 ti , these are your best bets. Avoid the 970 until they address the issue.
If you own a 970 already, register your product so that it becomes easier to place an RMA if they do a recall.
I now have a lot more information on the technical details of the architecture that causes this issue and more information from NVIDIA to explain it. I spoke with SVP of GPU Engineering Jonah Alben on Sunday night to really dive into the quesitons everyone had. Expect an update here on this page at 10am PT / 1pm ET or so. Bookmark and check back!

Essentially it's the same as having a 3GB card with 500mb cache overhead, but they managed to squeeze in an extra 500mb of VRAM. So the full story is, the full specs of the card got lost in translation when pitched from the technical writers to the PR team and they advertised it as a 4gb card when it actually is only a 3.5gb card with 500mb cache.
TL;DR They lied about the specs, but nothing's malfunctioning so you're good. Also I'm psychic, sort of.
