970's having performance issues using 4GB Vram - Nvidia investigating

Not open for further replies.
OMG, this thread. Soooo many people loving the 970 in the owners thread, now I see half of them hear ragging on it. Even though they have absolutely no real world performance issues, most probably running 1080p. lets all jump on the drama train, choo choo!!
 
It turns out that GeForce GTX 970 56 ROPs, not the 64 listed on reviewers guides back in September and such knowledge leads to interesting questions. Nvidia has clearly known about this inaccuracy for some time but has deigned not to contact the technical press with an update or explanation. Having fewer ROPs isn't a huge problem for the top-end of the GeForce GTX 970 - we'll explain why a little later on - but does have important ramifications for the memory subsystem, and answers the 3.5GB/0.5GB issue referred to above.

Checked. In both afterburner and gpuz.

interesting, did they both read the same then? and what were they reading? any chance of a video?

Upset that Nvidia is getting a lot of crap for their poor cost-cutting tactics. Why would anyone dare say anything bad about Nvidia? :rolleyes:

Oh wind your neck in. Do you even understand what you're saying? the 970 chips (most, perhaps not all) are rejected 980's with faulty blocks. turning them in to 970's , rather than chucking them in the bin, is the very definition of cost cutting and it's a common, sensible business practice. I'll ask you the same question i asked somebody else in this thread; what you you rather nvidia do? design a complete bespoke die just for the 970 and take the hit in tooling costs and profit?

No, you wouldn't.

May end up moving from 780 sli yet. Stick this pair on auction, buy some cheap 970's and still have money left over.:D

Though tbh, ive scan read this thread and it doesnt seem like a massive problem.

If you are used to 3gb cards it does not matter who is right in this debate the 970s will have more VRAM than your current cards.:)

Chance of free stuff, or money back.
Ignore the fact i would never have know about any of these if it wasn't for this thread! It's the principal goddammit*




*Only when chance of free stuff etc

I have and yup there is a difference, once I hit over 3.5 there's mad stuttering, I brought it up in someone elses thread about a week or 2 back, I've been holding out for a driver hoping this issue would be fixed but it doesn't look like it's happening now.

Games I've noticed this in are Dragon Age, Battlefield and Shadows of Mordor.

The others are Assasins Creed Unity and Far Cry but they're not the best examples to use.
 
I am with Tonester on this and was thinking of getting a 960 for a TV build but now I will be able to pick up the gimped 970 for much less in the MM from all the angry 970 owners. :D

As for those who feel they are warranted a refund, good luck with that.

What res, (particularly in battlefield)? Ive played it under DSR at 2560x1600 and most vram ive seen used was 2700mb, (3 gb 780's here). All settings maxed, x4 msaa.
 
Well, I don't want free stuff and I don't actually want to have to return anything. I was prepared to even get a third thinking performance issues were just down to drivers.

On top of that, had all this been clear from the start I never would have gotten 970's.

So, yeah, I will try and get my money back even if have to go through credit card company.

I don't know why some of you are taking as if it's something personal against you.

If you are happy with the situation, good for you.
 
Well

To reflect Memory and Geforce GTX 970, Nvidia also updates the graphics card's specifications, where the number of grid units now amounts to 56 pieces while the L2 cache reduces to 1.75 MB.

So essentially the GTX970 is 224bit card with 3.5GB memory and that last 512MB is 32bit.

No wonder I was getting borky performance at 4K over 3.5GB (SLI GTX970s)

This.
 
In an effort to reduce negative publicity, nVidia marketing have announced the specs of the 980ti


CUDA Cores 4096
Texture Units 512
ROPs 256
Core Clock 97Ghz
Boost Clock 195Ghz
Memory Clock 128THz GDDR5
Memory Bus Width 1024-bit
VRAM 24Gb

The press release uses the term 'honest, guv', 'the technical team swear it's true' and 'ooh look! A squirrel!'

The card will definitely NOT be a chicken drumstick with an 120mm fan glued to it. nVidia fans are directed to form an orderly queue and be ready to phone their credit card company in advance to request an increased limit.

I recorded SoM and got stutter as well but mine was with 6GB cards. BF4 is generally ok but a lot of the time, it is server dependent and a couple of maps don't play nicely. ACU and FC4 are a mess of stutter, even with 1/2/3 cards. I actually completed ACU on the 1.3 patch, as the stutter was better there than the 1.4 patch.

I don't think ACU and FC4 are good things to provide accurate performance. I could care less about the NAI Benchmark.

BTW cards with Hynix tend to see the last 0.5GB limitation kick in a little harder. Me included. That is only over a certain threshold.
