chow choppe Posted June 21, 2011 Share Posted June 21, 2011 hi guys i bought a new machine today which has i 7 2600k processor i have put 16gb of ram in it but when i am rendering with vray its only showing usage of around 3- 4gb in the task manager. i changed the memory type to dynamic and vale from 400 mb to 10000mb but still its using just 3 gb that is what i see from the task manager. please tell how to make use of my 16gb ram to have faster renders PS CPU usage shows at 100 percent while rendering Thanks Link to comment Share on other sites More sharing options...
Tommy L Posted June 21, 2011 Share Posted June 21, 2011 RAM doesnt speed up renders. RAM is like money, you notice when you dont have enough of it (crash or dramatic slowdown), but having extra doesn't make you any happier. Link to comment Share on other sites More sharing options...
chow choppe Posted June 21, 2011 Author Share Posted June 21, 2011 that means its a waste if my scenes are not that complex to require more than 4 gb of RAM? what does speed up the rendering in that case? i am confused Link to comment Share on other sites More sharing options...
notamondayfan Posted June 21, 2011 Share Posted June 21, 2011 Processors control speed, and to some extent motherboards, harddrive speed, and network speed. If the task manager shows you are only using 3gb, then that's all the file needs. I have 12 gig here at work and I have never ran out of RAM. 16 gig seems like a hell of a lot of RAM, and if I was pushing anywhere near that then I'd be looking at optimising files rather than buying more RAM. I guess you're future proofed though with 16 gig!! Link to comment Share on other sites More sharing options...
Tommy L Posted June 21, 2011 Share Posted June 21, 2011 that means its a waste if my scenes are not that complex to require more than 4 gb of RAM? what does speed up the rendering in that case? i am confused Its not a waste, its a safety net. Some complex cg elements are stored in ram at render time (Huge textures, proxies etc) amd maybe in the future you'll need that. You also may want to run concurrent programs, RAM is handy for that too. Rendering (other than GPU rendering) uses CPU. Faster cpu and more threads = faster render.

gputhige Posted June 21, 2011 Share Posted June 21, 2011 I agree with Tom. I have two systems with 12gb ram and it was the same case earlier with the usage not moving above 3- 4 gb. But last project I converted all my trees into proxies (and also other objects like railings etc) and the system suddenly started using up about 10gb. I guess proxies do take up RAM and its so useful that the file size drops down dramitically. Rgds GP Link to comment Share on other sites More sharing options...
Nic H Posted June 21, 2011 Share Posted June 21, 2011 you need to add more textures, geometry etc to your scene also render at 20k that should use more ram hope that helps Link to comment Share on other sites More sharing options...
archigem Posted June 21, 2011 Share Posted June 21, 2011 (edited) hi guys i bought a new machine today which has i 7 2600k processor i have put 16gb of ram in it but when i am rendering with vray its only showing usage of around 3- 4gb in the task manager. i changed the memory type to dynamic and vale from 400 mb to 10000mb but still its using just 3 gb that is what i see from the task manager. please tell how to make use of my 16gb ram to have faster renders PS CPU usage shows at 100 percent while rendering Thanks Strange man.... u got a good machine... and why u r worrying?? as everybody else said.. it's like money. in case u got in to a big trouble (the big project) then the money can help. I think it's funny that u think if u have the ram... then u should use it to fullest. I mean u should always try to use less ram and resources as possible. If u own a ferrari, that doesn't mean that u always drive it to its full speed. But when u'll need it then the power will come handy. So stop worrying. it's not waste it's future safe and still do not try to use it just because u have it. You had to think about it before you buy the machine- what type of work you do and what RAM your work demands! Now when u got it, forget and cheer up. (Also RAM don't speed up the process. Neither the GPU. The rendering is all about processing power that's includes CPU and motherboard.) Edited June 21, 2011 by archigem Link to comment Share on other sites More sharing options...

alsoukar Posted June 24, 2011 Share Posted June 24, 2011 Its good help if you keep an eye on no of polygons in your projects you will find that 16gb do more than 4gb You can push it and few test New engines in 2012 allow you to use graphic card ram and gb so You will have more processing power I use 24gb ram and 4gb graphics card 8 cores of xeon with 64bit OS It very relabel system speed is not every thing got i7 with 10m ploy crash near the end and with xeon and more ram and 64bit OS will do the job with no problems Link to comment Share on other sites More sharing options...

avvid Posted July 1, 2011 Share Posted July 1, 2011 I'd say you need to be thinking the exact opposite: the less RAM you use, the faster your rendering (and everything else). If the rendering is taking-up a lot of RAM, it means the scene is very complex, which means the CPU has more work to do, to render it. If you have a complex scene that only uses 2 MiB of RAM while rendering, then you're a genius, and the rendering should be quick. Unless you have the death star doing your rendering for you, you should always try to optimise everything, as much as possible. Link to comment Share on other sites More sharing options...

Alyosha Posted July 6, 2011 Share Posted July 6, 2011 Well it worked for me, on my previous machine I had 12 gb of ram, and at one point I upgraded to 24 gigabytes. I did not change a single thing other than that, no software changes, no reinstallations, no other hardware changes, absolutely no settings changes in max - all i did was pull out the 12 gig ram and put in 24 gig of ram. But the rather complex scene that I worked on atm (cca 15 mio polys) performed obviously and substantitally smoother as far as viewport navigation goes. I don't know why or how, but thats what happened, and the change was so obvious (easier to work) that you can trust me on this one. Graphic card was a rather lame quadro 1800.

Alyosha Posted July 6, 2011 Share Posted July 6, 2011 I also think it's quite logical, because max needs to load the scene into the ram when it works on it, and the more comfortable it is ram-wise the smoother the workflow...I think though, that this might only be apparent when you push your ram limit to the...well..limit...when working on complex scenes.

In the 'Dynamic geometry limit' write '16384' (if you have 16 GB Installed in your PC). - Again in the same tab at the opposite side, there is 'Render region division'. Give the value 512 to 'X' (instead of 32 default). - This will only work if you are rendering high resolution image. Hope this will helps..!!

Scott Schroeder Posted July 22, 2011 Share Posted July 22, 2011 it's almost definately not, gfx card have there own RAM Actually, it's true. There is such a thing as shared ram that is shared between system and video, but mostly on older systems. So if you have a low memory on your card, say 256 megs, some systems are set up to share an amount of system ram. However this is usually avoidable since you take away from your primary memory to use as video memory, therefore slowing your overall performance down. I have no idea why you'd want to do this today with the onset of large onboard memory gfx cards. http://en.wikipedia.org/wiki/Shared_Memory_Architecture Link to comment Share on other sites More sharing options...
