2 gigs vs 4

[Steve Roberts]

Well, you’ll be able to make longer RAM previews, you’ll be able to keep other apps open (don’t forget OS overhead) and you’ll be less likely to crash during a render.

Anybody else?

It will help a lot with CS3 too, b/c it’ll actually use the ram….

Steve is very right too, the machine should be less finicky if you’re, say, checking your email and outputting some animation.

BUt I can’t figure on twice the ram preview can I? Just a jump … I am not concerned about other apps .. just getting AE with Zaxwerks pluged in, as fast as I can for ram previews

By default After Effects will only use 2 gig of ram even if you have 4 gig using windows 32 bit. There is a little fix so it will use 3 gig of ram. After you back up your boot.ini file, modify the last line to read “/fastdetect/3GB”. If done correctly you will see “3 gig of ram” when you start AE in stead of 2 gig.

buy nucleo, it’ll use as much RAM as you can throw at it

[Reggie Spires]

But not beyond the windows limit of 4 gigs right?

Where exactly is that file

Windoes XP will only make use of 1 Gig per program… Vista does more – at 3 Gigs…

Here is what I found at with a MS site search:

32 bit Windows: All 32 bit processes are limited to 2Gb but can extend to 3Gb if the program was compilied with the Large_Address Flag set, and 4 gigabyte tuning has been enabled to reduce the memory taken by the OS itself.

64 bit Windows: All 32 bit processess are also limited to 2GB but can be extended to 4Gb if compiled with Large_Address_Flag set. All 64 bit process are also limited to 2Gb but can extend to 8Gb with Large Address awareness.

With regard to this 3 Gig “barrier” in a 32 vs. 64 bit OS you might want to read this article.

You might specially note the effect of high Ram graphics effect on the RAM available… noted toward the end of the article.

Is that right? I’ve heard of many people running XP32 with 4GB RAM and AE using either 2 or 3GB of that (depending on the switch) with the OS and other open apps eating up the rest.

Never heard of 3GB being the limit that XP32 can see…?

I understand 512mb+ will be used by OS and PCI-E black hole, etc. But I thought that’s what the 4th GB was for – so you have 3GB to use for all your other apps…

Can someone confirm/deny any of this please, cos I’m about to buy some more RAM and new procs/gfx card and don’t want to get it wrong!

Thanks.

XP32 can see more than 3G of Ram… the issue is how XP uses the RAM.

It’s been a while since I have read the article, but if my memory is correct the key is how much memory is allocated per application. Also, the amount of memory your Graphics Card has has an impact on this allocation.
