3GB switch

[G-Vision]

Hello,

Is 3GB switch useful with only 1 GB RAM ?

No, you need more than 1.6gb of ram for it to do anything.

Hi jacksc02

i think you are wrong

the three gig switch doesnt have to do to much with your Ram. but with the swap file windows is allowed to use for very memory consuming programms.

in the windows ini, usualy you are not allowed to use more but 1.6 gig.

if your calculation takes more than this, which can happen easily, and which doesnt depend on your Ram, max crashes totaly.

the three gig switch fixes this by telling windows to allow more but 1.6 gig to use for a swap file for max, and so much heavier scenes can be calculated.

nevertheless the new vray hopefully will make this switch obsolet.

Hi Tom,

So when I made my swap 4GB and use 3GB swich, it will work fine?

Hi G-Vision

well i wouldnt put my hands in the fire for this

You first should take a look at the original 3GB thread somewhere here in the forum. Just search for it.

Some things depend on the Windowsversion and also the servicepack. But i would try it if i was you.

If i am not wrong, we have xp with servicepack 1. sp2 didnt work with it. But here i am not sure.

Nevertheless. the 3G Switch can save your live in big scenes that without had never a chance to get rendered. And if this wasn´t enough, vray proxys are exactly the solution that was done for this !

Geddart some time ago rendered a testscene (with repeated Geometry, no gi...) wigh about 3000 000 000 Polygons. YEEES it was slow, but it did the job.

So far, Good luck.
