The 970 has the same memory specs as the 980 so shouldn't they run the same
The memory controller on the 980 is different

Interesting video, may finally be showing what is going on. Or maybe there are other factors affecting his performance? His posts keep getting deleted from nvidia forums, so someone doesn't want it being shared or maybe a fake video somehow. youtube.com/watch?v=wgRir5JwKyU&feature=youtu.be

That is a very well done video on his part, so hopefully it doesn't catch any flak. It does show that it can use the full 4gb temporarily, many state that it won't even do that, but it can only maintain 3.5gb. I think it would be best for NVidia to compensate through some form and relabel the 970 as 3.5 with a .5gb nope zone. Thank you for sharing that aliensf. 1st post in 6.2 years of being a member :-)

Probably some of people here have similar result -GTX 970 3.5GB Vram Issue - NVIDIA GeForce Forum, https://forums.geforce.co...-970-3-5gb-vram-issue/ This mostly hit brands who are specialized for NVIDIA cards because no other source of earning from GPU market as MSI, ASUS, GIGABYTE,... Even people from EVGA are owners of same model in their rigs.

PCPer posted an interview with Johan Alben (SVP of GPU Engineering) explaining the GTX 970 architecture
Hmmm, I think quite a few people will be asking for refunds here and I can't say it wouldn't be unreasonable.

Looks like Nvidia gave out the wrong specs also. Pulled from Anandtech article.

I understand people situation is disgusting, but actually EVGA, ASUS, MSI didn't done nothing wrong, that's not false advertising from their side.
NVIDIA should resolve situation on some way, or to provide refund to EVGA and others for some number of cards to reduce impact.
At the end that's their mistake, it's not fair NVIDIA to pass without hit because they sell GPU to manufacturers.

I would be perfectly happy with an optional bios update to disable the slower partition. Id rather not have it at all than have the card try to use it and make performance worse. Sadly, I don't think there is anything else NVIDIA can do for us other than take the cards back, and we know they aren't going to...

Theoretically, with massive effort from Nvidia, yes. But it's highly doubtful that we 970 users get that much love, especially when Nv decides to move on and release a new generation/updated version of its line of products. The scenario I'm afraid of is that once more and more games "require" 4 Gb of VRAM in maybe 1-2 years, they might run well on a 980, but much worse on a 970.

Ok so, I've been following all of the most recent news in regard to the issues with the 970 and I whilst I understand the basis of the problems, I am still a little unclear as to what to do next with the two I have sitting in unsealed boxes just having been purchased (2/1/15) for a new build I want to get started on.
With the main bulk of information saying the 970 is not all it should be, yet some other information saying "Yeah its flawed but still a good card", I'll be honest and admit the sheer volume of readable opinions has been a bit heavy to wade through. And I'm none the wiser.
I'm not exactly a technophobe, but sometimes a guy just needs it plain and simple. Seeing as I've only just purchased them and they're both exactly as they were delivered, I'm still well within my rights to return them under an RMA from the vendor and request a refund or exchange for another spec card. But I'll need to be sharp and get it sorted asap, if that's the way forward.
Thanks fella's and I appreciate any input in regard to my post :)

Hmm, it depends how do you want to use those cards. If you want to play in 2K or even 4K you maybe shall wait for more reviews on games demanding >3.5GB of vram and with focus on this particular issue. There are some users reporting a visible stuttering if memory is exhausted, for example Shadow of Mordor. If this is true, then you could get stuttering in most game you would play in very high resolutions. I plan to play only in 1080p so for now this issue will not be so obvious but with more and more vram demanding games this could be a problem. The only thing we can do then is to reduce texture quality so the game will never reach 3.5GB.

The ones saying "Yeah it's flawed but still a good card" are expecting Nvidia to come up with a fix. As of right now, no its not a good card and Nvidia has not announced that they are officially going to do anything about it at this time. There is a lot of speculation and hope that they will, but nothing is a guarante because this is a hardware issue and not a software issue.

I purchased the SSC's as soon as they came in stock. Was having multiple issues and this was the last straw. I had been wondering why games would sit at almost 3.5Gb on the RAM and that with the SLI voltage issues these are boxed up ready to be returned. They can say what they want but all I know is my 770 lightnings don't have the same voltage issues. The people who are going to be hurt the worst is companies like EVGA, they did nothing wrong, but they are going to get a black eye from consumers who don't know who the real bad guy is. I still have my EVGA 750 Ti in the kid's PC, and I guess I am waiting for my upgrade. Maybe a x99 setup? but my 3770k still runs fine....... 1st world problems......

Folks, this is interesting, because of this issue I just tried to run some memory tests in OC Scanner - Furry E memory burner and what I got is surprising - well not after this issue has been discovered. There are actually 3 presets. 1. Memory burner using 1024MB of vram 2. Memory burner using 2048MB of vram 3. Memory burner using 3072MB of vram - but actually this utilize full 4096MB of vram, I think the preset naming is bad. What is bad here is that while for 1024 and 2048 I get exactly the same 151FPS, for 4096MB I get only 47FPS !!! The only difference in this test is amount of used vram. This could confirm that if more than 3.5GB is used, framerate will drop dramatically. But maybe I'm wrong... I hope... This really concerns me as it could be related to this issue. What do you think? See the screenshot. Would be great if someone with GTX980 could test it as well. If there are same FPS for all three presets, then we are done here :-/

@Squall_Rinoa86
but that 512MB Of VRAM will eventually matter! And it could make all the difference in terms of a stutterfest gameplay, or silky smooth gameplay. What Nvidia did was clearly sneaky, and wrong........Odd even! nearly 2,000 replies on this topic over on the Geforce forums. That is a lot of unhappy people. Like RainStryke said, basically if it's not what we paid for, we don't want it.

But didn't nvidia say the impact on performane is only 3-4% ?? According this it is 3/4 slower! They lied to us, PR bull****s, so they should compensate for that. My trust in Nvidia is gone, this will help amd a lot!

Also I don't know why everybody is talking about 3,5GB when Nai's benchmark clearly states that first significant drop (3x slower) occurs from chunk 25 what is from >3.2GB. So not 3,5GB but problem starts with 3,2GB!

I don't know how much of an impact AA has in this particular case but if you fill the VRAM with textures for instance the 970 is going to be in trouble.

Pretty sure that's because no one is running it headless and the ~300 MB is taken by OS
