hello, i was rendering for few hours than i noticed that not all my physical ram is utilizing by MAX im using scanline render is there anyway to use full installed ram in MAX

Unless I’m rendering millions of polygons with many high-res textures I never peak my RAM. I try to avoid it.

There’s no need to max out your RAM. It’s not even a good thing really. If your RAM is maxed out then odds are the system will be using swap space which can bring things to a crawl and sometimes crash the render; out of memory problems.

Using all of your RAM will not make the render go any faster. Period.

yeah ofcourse your right but in my case i have 4 gigs of ram out of this max using 902 MB ram that’s too low it think so

why should it use, anyway?

it will use at rendering much more, but not everything.

If it will use everything, then max will hang for some time, all max co-apps(e.g. menus) will display as many small opened programs instead of one Max, and none of them will be acceptable. if you use more sophisticated renderer(such as mr), renderer will fail, crash, or even Max may crash. I was with 3 GB for quite long period and hadn’t many problems with it, except if I was rendering scenes, or had open more than 2 Maxes and photoshop and reference images, music player and stuff

That is how it will look like.

actually OS and all behind the scene softwares takes up to 2GB ram(recommended), and for apps its enough to give them few GBs

The renderer will only use as much RAM as is needed.

You mention 900MB being used.

That 900 is allocated to the instance of 3DS Max that is currently running, the scene geometry, texture maps, shadow maps (if any), virtual frame buffer, modifier settings, scene settings and storage for computational information/results.

If 900 is all that is needed, 900 is all that will be used. If you want to increase RAM usage, try using higher resolution textures.

Are you SURE you are running the 64bit version?
I only ask because it has not been called “Studio” for a LONG time...lol

System specs in your signature mean nothing.
I can type whatever I want in there...show me a screen shot of your title bar in an open window of Max.

If you were using a 32 bit system, that would limit the amount of RAM you could use, normally to 2GB, or 3GB when using the 3GB switch. Not as low as 900MB.
But as stated, Max will only use as much RAM as the scene requires.
Remember, RAM is a place to store data that the computer is working with, just as a hard drive is a place to store data that is not being worked with. So it’s like saying “Why does this Jpeg image not fill up my entire HDD?”, and you would not be happy if it did, running out of storage is a bad thing.
If the scene, it’s maps and rendered image only contain 900MB of data, the remaining 3GB is not magically filled up with fictucious data just invented from nowhere or randomly loaded from the HDD, and it would not be a good thing if that did happen, it would be very bad in fact.
To sum up, if not all your RAM is used and you have RAM to spare, that’s a good thing, nothing to worry about.
If your RAM is getting full and running out all the time, that’s bad, it causes problems, and you should get more RAM so that does not happen.

yeah i just changed my textures and mesh quality to high than it used decent amount off RAM that’s good

and hello Doughboy12 those are the specs im using currently

For rendering it’s really almost all the CPU that’s important. RAM is a distant second for priority.

Not true if you run out of ram...you would then see it IS important.

Satya_Reddy there are MANY threads in the AREA where “we” hashed and rehashed a memory or performance problem with someone that “said” they were using 64bit, only to find out by looking at a screen shot that they were actually using 32bit...so I never assume that one your specs are correct or you “know” you are using 64bit, I have to SEE it to believe it.

Got it, thanks. It should only use what it needs then, nothing to worry about unless you are seeing a lot of disc use/access.

That’s it. If you are not using all your RAM, you don’t have a problem.
When your scene starts using the full 4GB, then you may have a problem.
But that is easily fixed by putting more RAM in your system.
It is healthy to have an excess of RAM.
