Your 970 gtx may have an "issue"

Weren't the heatsinks screwy with the 970s too ?

May of been limited to the cards with AC, can't remember.

Hopefully it's not a physical problem on the card itself & they can do some updates to allow them to access that memory, & avoid a recall.

Doesn't seem likely though :(

Poo. I guess us unfortunate owners will have to keep an eye on this. Can't say I've had any problems with my 970 yet.

Just thought I would share this. TLDR there seems to be a issue with the 970 gtx if it has to access over 3gb of video memory.

I just sent my 980 SC back to EVGA. It was really bad. It would just start flickering and pausing in the game. It was causing the computer to shutdown and the 980 fan would just take off full speed. I tried all the drivers and when I put my 780 ti back in, everything was fine. So I called and got an RMA and sent it back.

There is always something cheaper when compared to something else, but I would still expect it to work properly. Thanks for your contribution though.

Who tell's you is not supposed to be like that? The card works, people are using it to play and there happy. Now at least you know why it's cheaper. I always was wondering, why Nvidia would create competition under it's own roof, mystery solved IMHO
You are welcome.

Err no if the card cannot access all its ram correctly, then it is flawed, don't get me wrong, am an nvidia user, but these things can happen, and nvidia should naturally fix the problem.

NVidia said, it's working as intended. Also 670 have this problem. This isn't first time that when you disable something in card something else will work slowly.

anantechs take on 970gate.

to be honest I think it seems fairly a balanced summation..... (it is the same way the GTX660 and 660ti worked)

In the end while I am disappointed that these details haven’t come out until now, I am satisfied that we now finally have enough information in hand to truly understand what’s going on with the GTX 970 and what its strengths and weaknesses are as a result of memory segmentation. Meanwhile for real world performance, right now this is an ongoing test with the GTX 970. As the highest-profile card to use memory segmentation it’s the first time NVIDIA has been under the microscope like this, but it’s far from the first time they’ve used this technology. But so far with this new information we have been unable to break the GTX 970, which means NVIDIA is likely on the right track and the GTX 970 should still be considered as great a card now as it was at launch. In which case what has ultimately changed today is not the GTX 970, but rather our perception of it

===============
FWIW I do hope NV offer all 970 users something as a bit of an apology. The black and white of it is they missold the specs of their card. Would a freebie game suffice? I dunno really, but I dont imagine a full refund will be offered, tho that is what some people are expecting... Either way, people experiences crashes etc should be sending their cards back as faulty, the issue with using the last 500mb of ram is a drop in performance, it should not be graphical artefacts and crashes, and that would indicate a fault not a "hidden" design compromise.

(and it is only when going over 3.5gb, not 3gb)

I was under the impression that this was a buggy CUDA test app.. causing the GPU to allocate into system memory (which is obviously slow, compared to DDR5).

No mate, it is the last 500mb of VRAM. its still much faster than system ram but compared to the rest of the VRAM its painful which is why the GPU only uses it if it absolutely has to.

Am half expecting a product recall or chance to return our 970s for a refund. Not as advertised. I'll use the opportunity to upgrade to a 980 which will help with the strains of DSR on the Rift.

Yep. If they advertise and sell it as a 4Gb video card, then it dang well better be a 4Gb card, not a 3.5Gb card. I haven't personally filled it up much past 2.8Gb, so don't know what will happen if it needs more than 3.5Gb. Will it crash, stutter, explode? I dunno. Maybe I should contact the manufacturer and ask them...
