970 memory allocation issue revisited

....

224 bit must equals 224GB/s bandwith, but its not in all cases ( gtx 970).

time formula = max(X GB/196GB/s , Y GB/28Gs).

theoretical time formula = (X GB +Y GB)/ 224GB/s


as you see its not the same....

 

The 770 was a gk104 refresh of a 680. Nothing was cut on it. The 780 was a cut down version of a titan on release. I believe nvidia held back the 780ti and titan black until the 290/290x was released to gain back the crown so to speak. I do not think it had to do with yields IMO.

 

send an email to evga

I contacted evga and asked for a fixed card or any other solution.i advise that the owners of the gtx 970 will contact their card manufactor for a fix.if we all do that it could promote our cause in front of nvidia quickly.we didn't bought a card with those new specs.i'm waiting for a response from evga.mybe i'l go to the store and ask for a refond.

 

It wouldn't work though would it, as they'd have to market them as 970 GTX 3.5GB-4GB*


*Game dependent.

 

[05:48:49 AM] Hi, my name is Kenny. How may I help you?
[05:49:38 AM] John W: Hi there, I am not happy about the gtx 970 specs being changed after I purchased the card.
[05:50:03 AM] Kenny: Kindly accept our sincere apologies for the inconvenience you may have experienced.
[05:50:41 AM] Kenny: GTX 970 has 4 GB of vRAM However it has two memory segments. 3.5GB & .5 GB
[05:50:52 AM] Kenny: The GPU has higher priority access to the 3.5GB section
[05:51:03 AM] Kenny: When a game needs less than 3.5GB of video memory per draw command then it will only access the first partition, and 3rd party applications that measure memory usage will report 3.5GB of memory in use on GTX 970, but may report more for GTX 980 if there is more memory used by other commands. When a game requires more than 3.5GB of memory then we use both segments.

[05:51:55 AM] John W: What you fail to mention is that the final 0.5GB operates at an extremely low bandwidth
[05:52:52 AM] John W: Nvidia sold a product that doesn't exist
[05:52:59 AM] John W: the specs are different than what was sold
[05:54:11 AM] John W: I need 4gb operating at full bandwidth
[05:54:16 AM] John W: thats why i bought the card
[05:54:42 AM] John W: You advertise it as 4gb running at full bandwidth
[05:55:08 AM] John W: then after I buy it you say..."hey, actually, only 3.5gb is usable at high bandwidth"
[05:55:19 AM] John W: explain how this is acceptable?
[05:56:52 AM] Kenny: As you know 4GB is still there, it's just that it's designed in a different way
[05:57:42 AM] John W: But, when it accesses the final 0.5, the low bandwidth causes stutters due to high frame times
[05:58:01 AM] John W: So, oly 3.5GB gives acceptable in-game performance
[05:59:10 AM] Kenny: Did you try to play other games also and facing stuttering?
[05:59:32 AM] John W: Only have stuttering when I exceed 3.5GB
[05:59:41 AM] John W: before 3.5GB is smooth
[06:00:15 AM] Kenny: OK
[06:00:33 AM] John W: Ok?
[06:01:00 AM] Kenny: I mean I understand what you said
[06:01:33 AM] John W: Go on.....
[06:01:46 AM] John W: So, the card doesn't function as a 4GB card
[06:01:55 AM] John W: it functions as a 3.5GB card
[06:03:08 AM] John W: Also, the new specs are lower than the advertised specs
[06:03:45 AM] Kenny: Who is the card manufacturer?
[06:03:56 AM] John W: Asus
[06:04:09 AM] Kenny: OK
[06:05:21 AM] Kenny: Did you try to make the GPU run at better clock speed while gaming to avoid stuttering?
[06:06:02 AM] John W: The fps doesn't drop.
[06:06:28 AM] John W: I can get 60fps under 3.5GB smooth gameplay
[06:06:42 AM] John W: Then I get 60fps over 3.5GB, but I get stutters
[06:06:48 AM] John W: because of the bandwidth
[06:06:52 AM] Kenny: I see
[06:07:08 AM] John W: Nvidia sold cards that cannot run 4GB effectively
[06:07:25 AM] John W: Because the last 0.5GB has extremely low bandwidth
[06:07:33 AM] John W: A fact that was hidden before
[06:09:01 AM] John W: Why are you telling me to run the gpu at a better speed?
[06:09:28 AM] Kenny: That was to check if that reduces the stuttering
[06:09:38 AM] John W: But then my warranty would be void
[06:10:02 AM] Kenny: I think you are referring to Overclocking
[06:10:20 AM] Kenny: Overclocking the graphics card is one way to improve the Frame rate in games
[06:10:38 AM] John W: Poiontless conversation
[06:10:44 AM] John W: I am not overclocking anything
[06:10:52 AM] Kenny: The act of overclocking is to force a component to run at a higher cock speed than the stock speed shipped by the manufacturer of the product
[06:10:57 AM] John W: The problem is because nvidia lied about the specs
[06:11:00 AM] Kenny: I wasn't suggesting you to do that
[06:11:05 AM] John W: Yes you did
[06:11:11 AM] John W: you said run gpu faster
[06:11:17 AM] Kenny: I just was suggesting you to make the GPU run at the top speed which is supposed to
[06:11:21 AM] Kenny: That's not overclocking
[06:11:38 AM] Kenny: Overclocking is something you run the gpu faster that it is supposed to
[06:11:43 AM] John W: anyways, how do I get my refund for the card
[06:11:48 AM] Kenny: I can give you the steps if you want
[06:12:08 AM] John W: No, i dont want to overclock anything
[06:12:33 AM] John W: I want the card that has full access to the 4GB at full bandwidth as promised when i paid my money
[06:12:38 AM] Kenny: It's not over clocking
[06:12:46 AM] Kenny: That we will never recommend
[06:13:03 AM] John W: please stop talking about it anyways
[06:13:10 AM] John W: and answer the important details
[06:14:47 AM] John W: so, how do I get the card with the specs I bought?
[06:15:05 AM] Kenny: As explained before that is the design of the GPU
[06:15:04 AM] John W: Not the cut down specs trhat nvidia announced yesterda
[06:15:10 AM] Kenny: It is in 2 segments
[06:15:26 AM] John W: Nope, this wasn't explained when I bought it
[06:15:32 AM] John W: It was hidden
[06:15:51 AM] John W: The specs mentioned 4GB GDDR5 running at 224GB/S
[06:16:03 AM] John W: That is not what I got
[06:16:11 AM] John W: The specs said 64 ROPs
[06:16:21 AM] John W: I got 56
[06:16:50 AM] John W: The specs said 2MB L2 cache...I got 1.75
[06:17:22 AM] John W: There is 3 specification of the GTX 970 that is different from when I purchased the card
[06:17:38 AM] John W: So, how do I get the card that was promised
[06:17:39 AM] John W: ?
[06:18:21 AM] Kenny: The card will remain as it is
[06:18:52 AM] John W: The card is not what I paid for
[06:19:04 AM] Kenny: if you have complaints I can pass it along as a feedback to the next level team
[06:19:55 AM] John W: No, just confirm the following answers to these questions.
[06:20:13 AM] John W: Will Nvidia give me a refund for my GTX 970?
[06:20:38 AM] Kenny: For Refund you may need to contact the graphics card manufacturer as we are the chipset maker
[06:20:53 AM] Kenny: However I can understand the concern you are pointing out
[06:20:54 AM] John W: The chipset maker who lied about the official specs
[06:21:03 AM] John W: Answer yes or no
[06:21:12 AM] John W: Will Nvidia give me a refund for my GTX 970?
[06:22:40 AM] John W: Will Nvidia give me a refund for my GTX 970?
[06:23:32 AM] Kenny: Refund/warranty issues has to be addressed by the graphics card manufacturer, however I can pass it along to the concerned team.
[06:23:43 AM] Kenny: I can pass your case to the next level team
[06:23:49 AM] John W: Yes or No
[06:23:51 AM] John W: Will Nvidia give me a refund for my GTX 970?
[06:25:27 AM] Kenny: Your case is being already Escalated to the next level team and they will answer this question
[06:25:54 AM] John W: Ok, I will await their respomse.
[06:26:02 AM] Kenny: Appreciate it
[06:26:12 AM] John W: Thank you for your time, have a nice day.
[06:26:19 AM] Kenny: Most welcome

How original!

 

You did good.

 

I ment that amn3s1ac did good.we need the pressure.

 

The driver already tries to intelligently allocate the last 0.5gb only when needed, and in a way that doesn't cause stuttering (and btw, I have yet to see any conclusive evidence that accessing the last 0.5gb actually causes stuttering. and no; loading up a game with ridiculous settings like downsampling + 8xmsaa to force 4gb allocation doesn't count because you'd almost certainly hit other bottlenecks before any memory bottleneck became apparent). Its possible that there could be some specific cases where it causes stuttering, but definitely not the 'accessing the last 0.5gb always causes stuttering' nonsense people keep claiming with little compelling proof.

Without that last 0.5gb it would just swap out to system ram instead which would be even slower...

 

Original meaning posted multiple times by brand new users?

 

So 56ROPS and 1.7mb L2 then, kinda shady..


Im kinda glad I didn't wait for GM204 and opt for 780 when I did, got it @ 970 price anyway.., Not that I would bitch now, but still false advertising.


Also that CUDA benchmark is kinda flop, so dunno why people keep mentioning that, the maker said its flawed, also it seems win7 is the biggest conflict here, people keep saying it has this drop even in headless mode, while some dont have it in win8 @ headless mode.. So that does tell something.

 

I'm a GTX 970 owner just like you.

It would probably be good for Nvidia to code into their drivers for the GTX 970 not to use more than 3Gb of its Vram so that the full bandwidth of memory access is retained.

 

This makes absolutely no sense, if they did this it would make things even slower when a game tries to use more than 3gb because it would be swapping out to system ram.

 

You could physically remove 1gb with a hammer, put it in the microwave for good luck, then duct tape it back on. This procedure, in rare cases turns 970`s into brick cards. Use at your own risk. Sticky guide coming soon.
Seriously though, nothing suprises me in this section anymore, pretty sad state of affairs.

 

Older cards get by with using 3Gb or less Vram. I guess the GTX 970 was really meant to be a high-end 1080p card. For higher resolutions, get a 980 or older cards using 4Gb or more Vram.

I play ARMA 3 and there is a start-up parameter that I use to now limit Vram allocation to 3Gb. I now get less stutters and slowdowns.

 

If they knew they had to give a refund, why didn't they ??

 

If NVidia took steps at this point to limit the card to using 3GB, after having advertised the card as having 4GB, then having to admit that it's been partitioned as 3.5GB + 0.5GB, there is nothing that would protect them from class-action lawsuits other than refunding every GTX970 owner or replacing every GTX970 with a GTX980 at no additional cost to the customers.
