Nur 3.5GB nutzbar!

Das Problem scheint weit schlimmer zu sein:
"Bris Vorontsov from ENBseries claims that the GTX 970 actually only has 3.5GB of usable VRAM at any given moment and that system RAM is used in place of the last 0.5GB of VRAM. He also claims that this can be easily proven by allocating blocks into VRAM and then dumping system RAM. By searching the dump, you can find the codes of those last 0.5GB blocks of 'VRAM'.
Also, many people on Nvidia's forums are claiming sudden high system RAM and pagefile usage when using MSI Kombustor to test VRAM, particularly when testing the last 1gb of the 970's VRAM. Apparently, once the benchmark reaches 3gb of VRAM, system RAM and pagefile suddenly shoot up to 6-9GB (depending on how much RAM you have installed). One user posted: "Do the 1 GB test, then the 2 GB test, the program should use under 1000 MB of system memory. Watch your System RAM and page file shoot up ridiculously with the 3 GB test. It's like the whole framebuffer is being off-loaded to system memory.""
