GTX 970s can only use 3.5GB of 4GB VRAM issue - Page 9

post #81 of 2990
I will test this on my new EVGA SSC+ 970. Will run SoM 4k with Ultra texture pack which draws 3.8GB on my 295x2. Will report back my results probably tomorrow.

Apparently, according to someone on the nvidia forums, there may be grounds for a lawsuit
Quote:
I too am an owner of the 970 chip, precisely the MSI GTX 970 "4Gb" card. I'm currently attending my second year in college and heading into the computer science, software engineering fields where I intend to major. Anyhow, Nvidia breaching their advertised chip statistics kept bothering me all day, so I paid a visit to my dads lawyer after lunch and he told me that if it does in fact turn out that the cards cannot exceed 3.5Gb or live up to the expectations of the given stats by Nvidia, there is room for a lawsuit(s).

I gave him all my info (all the agreements and such of purchase) and he'll get back to me later this week or early next week. But the important part which he emphasized several times is DO NOT UPGRADE from here on out because that will void the current agreement, meaning if Nvidia covers all the loopholes in the purchase/upgrade agreement with the next driver update, and you choose to update, you abide to the updated drivers agreement. So, if a new driver update does get released, don't instantly update. Let the pawns go first and see if the update fixes/improves the issues or if it'll be Nvidia covering their as**s.

Edit: Spared some of the details, and it is fairly late here (3AM) so forgive for typos, poor sentence formation, etc..

The 970s definitely can exceed 3.5 GBs, we have evidence of that. I've seen it using 4 GBs on my own. The issue is more along the lines of when the 970s decide to exceed 3.5 GBs and what happens when they do; they're acting differently than 980s in this regard, apparently.

so the lawyer says do not upgrade your drivers, what in case Nvidia fix a bug? Is he saying that any unfixed bug is grounds for a lawsuit?

I've performed my own test: filling in the VRAM with textures. For my machine and config, everything seems fine:

There is a link for the small app (d3d11) if you wish to test yourself.

If you have any questions, feel free to ask.

I think he means the Drivers can have a License Agreement, where it states if you update then you cant sue them for previous stuff.. Something in that way tongue.gif

I understand that, their drivers also disclaim any responsibility.
A lawsuit would be difficult, as I can see a judge considering any request by Nvidia to update drivers, as an attempt to rectify the problem.

I think its more in the case that nvidia release a driver update that doesn't fix anything just so you can accept new agreements

If it turns out that a driver fixes it then no need to worry, everything is dandy smile.gif

But the thing is, can they really? unless i read something wrong i haven't seen any go past 3,6 GBs when PF is turned off... So far it would seem that it uses ~3.5GB on it's own and then uses/caches everything else on PF.


edit: spelling..

There is a clear evidence it normally goes up to 4GB of VRAM. Just up there on my video. You can also test yourself.


Now, what bothers me is what driver does in the background with different type of memory structures. It is not a trivial work since memory management in DX11_0-11_1 is quite a bit different than DX9.
