Mozda lazu, nisam siguran kome da verujem.![]()
Moze to biti i 4GB, ali koliko od toga je VRAM a koliko sistemski RAM? Jedino je relevantno sa odgovarajucim testom proveriti brzinu pisanja/citanja memorije, to tacno pokaze sta ide u VRAM a sta u RAM. Ova 2 SS ne pokazuju ama bas nista![]()
pokreni jso jednom test, vidis da pred sam kraj opet imas punu brzinu. Nesto ti je tu stucnulo![]()
From Nvidia Chat Support this afternoon - (names changed)
[10:11:39 PM] NV Chat: We have our entire team working on this issue with a high priority. This will soon be fixed for sure.
[10:11:54 PM] Me: So, what is the issue?
[10:12:07 PM] Me: What needs to be fixed?
[10:12:46 PM] NV Chat: We are not sure on that. We are still yet to find the cause of this issue.
[10:12:50 PM] NV Chat: Our team is working on it.
Dobro je da bar priznaju da je "issue", sad samo da sacekamo resenje.
A pazi sad ovo: http://www.neogaf.com/forum/showpost.php?p=148930490&postcount=640Pazite sad ovo... kako je program uspevao da "alocira" tj. da popuni sve vise i vise momorije na grafickoj fps je DRASTICNO opadao.

Nisi nam rekao koliki je VRAM usage (GPUz itd.) pre nego sto si pokrenuo taj test. Ovako nam nista ne znaci.
Stavise, ja ne bih uopste koristio taj alat za benchmark, jer se u vise navrata pokazao kao nepouzdan.

Test stalno menja rezultate.Nesto tu ne stima.
@danilo989
Igrom slucaja imam gts 450 u rezervi i u msi kombustor-u mi na memory testu uzima 960 od 1024 mb.
Medjutim na gtx 660, na testu od 2gb ne uzima vise od 1760 mb.Ako otvorim browser zauzece skoci na 1850mb.Zasto mi sistem "cuva" memoriju?
Mozda je tu problem i kod gtx 970?
^Kombustor nece uzimati vise VRAMa nego sto mu je potrebno za datu rezoluciju i filtriranje/umeksavanje ivica. Probaj da povecas Anti-aliasing u podesavanjima kombustora ili povecaj rezoluciju pa pogledaj zauzece memorije.
Edit: pogresio sam, mislo sam na neki drugi test, Kombustor memory test bi trebao da zauzme sto veci deo memorije. U tvom slucaju je Windows rezervisao svoju porciju koja ne moze da se testira. Slicno kao i regularni RAM, moras da bootujes sa CDa/USBa da bi ga u celosti testirao. Nemam mogucnosti da testiram, pa ne mogu sa sigurnoscu da odgovorim.
Sve u svemu, treba imati strpljenja i sacekati nVidijin odgovor. Ima previse nepoznanica da bi se izvukao definitivni zakljucak.
Edit 2: NVIDIA Responds to GTX 970 3.5GB Memory Issue
http://www.pcper.com/news/Graphics-Cards/NVIDIA-Responds-GTX-970-35GB-Memory-Issue
Ne znam jel' citamo istu stranicu...? :whip: Po njima razlika u perf. izmedju 980 i 970 pri >3.5 VRAM je par procenata. Gde je tu problem? Ako ne verujete nV izjavi to je vec vasa stvar. Sacekajte FCAT testove za >3.5 VRAM slucajeve i kraj.
Our own Josh Walrath offers this analysis:
A few days ago when we were presented with evidence of the 970 not fully utilizing all 4 GB of memory, I theorized that it had to do with the reduction of SMM units. It makes sense from an efficiency standpoint to perhaps "hard code" memory addresses for each SMM. The thought behind that would be that 4 GB of memory is a huge amount of a video card, and the potential performance gains of a more flexible system would be pretty minimal.
I believe that the memory controller is working as intended and not a bug. When designing a large GPU, there will invariably by compromises made. From all indications NVIDIA decided to save time, die size, and power by simplifying the memory controller and crossbar setup. These things have a direct impact on time to market and power efficiency. NVIDIA probably figured that a couple percentage of performance lost was outweighed by the added complexity, power consumption, and engineering resources that it would have taken to gain those few percentage points back.
Pa nisu ljudi kupili kartu sa 3.5Gb nego sa 4GB kakva je ovo blamaza od obrazlozenja tj. opet sisanje ovaca, moze im se dok imaju naivni koji ce prihvatiti ovo![]()
Meni je veća blamaža, tvoje frljanje sa gigabitima i gigabajtima.![]()

kod mene ne menja, uvek je isto.
Nista sutra uzimam GTX970 dajem oglas kupujem polovnu GTX970dobicu za nju novu GTX980 pravi dil.
