3ds Max 2009 x64 not utilizing enough ram???

[rythem_of_the_nig]

Hi friends....im using 3ds max 2009 x64 along with vray 1.5 sp2 on Xp x64 OS.I have 4 gb ram installed in my system but while rendering, 3ds max uses hardly 500 to 800 mb of ram and it takes lot of time to render scenes.Please help me find out whats wrong in there. I simply want max to utilize as much as ram as possible.Is this problem with max or vray?

please help me.

 

System specs:

Amd turion 64 X2 1.8ghz

ATI radeon x1250 onboard

2*2gb ram 800mhz.

120gb HDD.

possible solutions:

if you have a lot of proxies and displacement, try to

increase your dinamic memmory limit on vray system panel...(400 mb default), put 1200 or something like this...

 

if you have some proxies, try to put the original meshes, will take more ram, but the calcualtions will be faster...use the proxies only to save ram..

 

take in account that not allways is possible to use all the ram, sometimes the rendering times are depending on other calculations, like subdivisions, light quaility, noise etc.....more ram memmory not allways made this calcualtions faster,..

 

wich processor you have?, how is the scene?, how much lights...

if you put the vray settings i can help you, but in this way looks like a lottery..

Im sure Andrew or someone will correct me if I am talking out my rear, but generally, rendering is about processors... Pretty much thats what is going to dictate your rendering speeds.

 

RAM will help, but essentially, its the processors, and Im not sure that making all those changes will effect the render times a huge amount. The OS's are pretty effective at using as much RAM as they need, so if you are bottoming out on 800mb, I would look at things like:

 

Lighting

Scene Size (pixels)

Displacement, as mentioned.

 

You need to give a few more details out about the scene etc really, as Juan mentions.

Again, correct me if I am wrong, but isnt the AMD Turion a 4 odd year old laptop processor..?

 

Have a look at Tomshardware, and see what sort of speeds you get out of one of those. I would almost certainly say now, that its the processor that is one of the causes of slow rendering.

 

Again, more scene details would be useful, but thats where I would think the bottle neck possibly starts.

Okay feel free to also correct me if I'm wrong but my interpretation of the OP's post is. I have 4GB of ram so why isn't max using all of it rather than just 500-800mb. My answer would be similar to the above, just because you have 4GB of ram it does not mean max will need to use it all every time it renders. It will dependant on what is in the scene & it will only use what it needs.
