2gig of Ram?

[marcbon31]

Hi guys I always find some help here...

I had been tryng to find any post related to xp64 and 4 gigs of ram but with no luck, im rendering and my computer and it is using nearly all the prossesor power...but never more than 2 gigs in the ram department.. is a dual core with prosesor 2.6MHz with four gigs of ram.. windows xp64..and Im running max and vray 32bits.. the task bar shows all the ram but is not using it...Why?

thanks for any advise...

It will only use the ram if it needs to.

 

A CPU-intensive scene is not neccessisarily a memory-intensive scene.

 

BUT - ram is (currently) cheap and it's better to have it than not, eh?

 

I have an idea that if you started rendering an animation sequence of a 4+ million poly scene with 36 lights, with shadows and reactor moving 50+ trees, that your ram usage would go up.

you mentioned max and vray 32bits. could it just not be addressing more than the 2gb b/c they are 32bit? oh - maybe not because you can address up to 3gb on xp 32bit machine?

While this thread attracts those in the know.. can anyone explain to me how my 32bit Vista installation see's all 4Gb of my Ram?

Because it's Vista and it's "rounding up"?

 

Seriously, I wouldn't put it past Microsoft to 'round up', to avoid questions from thousands of people.

 

And it's true - there is 4 gigs of ram in your machine.

For 2 people who say I should see all mem - i heard in latest Vista service pack, it shows amount of physical installed memory, not amount of available.

because its vista and not XP...

Thats bulk dodgey.

I am sorry I could not answer before... but my machine is 64bites... the memory shows up but is not been used....????

why are you using 32 bit max on 64 bit machine and secondly ...try a huge scene with lots of meshes and displacement ,proxies and see if its using up the 4 gig memory

[bsm3d]

The RAM amount displayed by Windows is direclty from the Bios information.

 

Eg. If you have 4 GB RAM and Bios only display 3.2 GB, Windows only display 3.2 GB, but if you BIOS display 4 GB, Windows diplay 4 GB, so in 32 mode he only use 3.2 GB RAM maximum, the rest as the motherboard permit is automatically allocated to shared PCI device.

 

Sometimes with 4 GB on 32bits system you can get more free ram for your applications as system us the upper allocated to shared device (PCI, PCIe, IRQ,...)

 

SO in 32 Bits system applications is limited to 2 GB per applications ! but you can force application to use more than 2 GB with the Boot switch /3GB (put is in boot.ini at the end of line)

 

eg. "multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows XP Professional Edition" /noexecute=optin /fastdetect /3GB"

 

I hope that's usefull for you.

 

Best,

64 bit max don't have all plug-ins complited for X64 Edition, eg. in Max 64 there is no more VRML impoter!

 

So it's probably why Autodesk allowing to install both 32 and 64 bits editions on the the same system.
