Gpu eating ram?

[Edwinmartz]

Hi guys
I recently watched this youtube video where a guy is building a new computer (hes completely overkilling on the components)
But he actually talked about something that really intrigued me

While installing the dual watercooled cards gtx980s ti or titan x i believe

He mentioned that the amount of ram has to be greater than the video ram

Is this true?

So if i was to run a 980ti on my 8gb ram computer i would only be only left with 2gb system memory?

How does this work
Im really confused

Im about to build a new desktop and id really like understand this before my build

RAM is only a bottleneck if you run out of it, as we speak I'm using 2-2.5 gigs or RAM so yes you'll want more system RAM than VRAM. A lot of people with 980ti(6GB)/390(8GB)/390x(8GB) still have 8gb of RAM because they're not running settings that max out VRAM, the FPS on a game are too low at that point therefore not maxing out their VRAM.

If your GPU/Settings isn't at 60+FPS including minimum FPS than you're going to turn something down and than your VRAM/RAM usage goes down. At 75 FPS/HZ games look so smooth, it takes a very specific person to prefer higher settings/lower fps/higher VRAM usage. Same thing happened with the 970 3.5GB VRAM scandal/testing, settings had to be ridiculously high and FPS ridiculously low before the 3.5GB VRAM was exceeded.

Conclusions: GPUs slow down to unacceptable performance before they run out of VRAM in most cases.

I'd say it was BS with regards to it consuming RAM, you will naturally have more RAM than VRAM.

Historical footnote, there were issues in early versions of win7 (possibly 8 though now I think more about it) whereby the VRAM would be duplicated in main memory, this obviously caused problems. But a very early update fixed this permanently.

However if you are building soon and looking at a higher end system then wait for pascal.
