Why is Ram Usage so High vs Video card usage Question?

MB Ram Usage vs Video card usage Question?

Why does Octane consume so much MB ram, video card has 8192 of vram

Memory

GPU Used : 1834
GPU Free : 5906
GPU Total : 8192
OOC Used : 0
OOC Max : 4096
SYS Octane : 83
SYS Used : 7427
SYS Total : 36860

Can someone PLEASE explain what exactly is loaded into Video card memory, and what is loaded into MB memory???

I just don't understand this, LW scene loaded using Object memory 1771.4 M.

I just don't understand why the Video card memory usage is so LOW???

Objects 210, Polygons 3681675, textures 10 (32bit)

No MB..
No Instances...
No deep image enabled..

No IPR open MB ram usage at 4.52 gig, IPR open MB usage goes to 7.62 gig

F9 render MB usage is at 7.48 gig ram, video card is (Used/Free) 1846/4139

I have 2 video cards, ok

one with 6 gig, the other 8 gig, when rendering F10.
memory is [ Memory (Used/Free): 1846 / 4108

I know the system is utilizing some video ram, but I was wondering why octane does not use more memory video card wise, it is consuming 7 gig of MB ram ?

just curious that's all to what is sent to the video card cores??

IF you use both GPUs in Octane you will have only 6 GB VRAM available for octane 'coz it can use only what lowest GPU card has 'coz it sends data to both GPUs in parallel (VRAM is not combined) so in your case you can't use more than 6GB when rendering with both GPUs.

Also in this case it depends which GPU do you use to drive monitors/feed LW OpenGL. LW will also use VRAM for textures OGL and Windows use 300-500 MB for monitors display depending on resolution, number of monitors etc. etc..

Also if you are in windows 10 or windows 8.1 (comparing to win7 and win8 ) you will have even less total VRAM available due Microsoft new thing which reserves VRAM memory for itself so Octane can't use it.
