Elliot Posted June 18, 2006 Share Posted June 18, 2006 My machine is an old one, (1.4 years) it is a Dual Opteron 250 with a Tyan 2885 motherboard and 8 sticks of memory. Four 512mb for each processor. The memory is TwinX Corsair CMX512RE-3200LL. During the first few months everything worked fine. Then VIZ started crashing once in a while. (I considered this normal with Viz). During the last few weeks I installed Premier 2.0 and After Effects 7.0. If I have a nice size file the machine will almost crash right away when trying to process the movie. I installed one of those free memory monitors. What I am seeing is that the memory is being consumed like crazy.... I see the safety bar on the monitor going from the green to the yellow warning and then the computer crashes. I thought the memory was suppposed to refresh. Why is this happening? I have a 620 watts Power Supply and a SCCI Adaptec Raid 0 with two High Speed Seagates. For back up memory I have a Raid STA with two Western hardrives. When I put 4 stikc of memory the machine will recgnize them as 2gb of RAM. However, when I place all the 8 sticks the machine only recgnizes 3gb of memory. Is this normal? Any ideas...? Thanks Elliot Link to comment Share on other sites More sharing options...
mtutaj Posted June 18, 2006 Share Posted June 18, 2006 windows xp only recognizes 2.5 gig of memory. otherwise you have to install the 3gb switch. and I think that only gets you to 3gig. Not sure what the cut off is for XP. There has been lots of discussion on this topic on these forums. Mike Link to comment Share on other sites More sharing options...
Elliot Posted June 18, 2006 Author Share Posted June 18, 2006 Mike, Thanks for the response. What is the 3gb switch. Is that a software...? Where can I get it...? Will WIndows recgonize 2.5gb per processor or for the entire machine. My dual processor motherboard has a bank of memory for each processor. My machine says it recgonizes 3.06gb, but the RAM monitor only reports 1.5gb. On my task manager I only have 22 processes going on.

mtutaj Posted June 18, 2006 Share Posted June 18, 2006 its for the entire machine. you usually need to use windows server for anything more. the 3gb switch, is a registry hack. that you have to change the settings yourself. Here is one of the many threads on the subject. http://www.cgarchitect.com/vb/15719-3-gig-switch.html?highlight=3gb+switch Mike Link to comment Share on other sites More sharing options...
manta Posted June 18, 2006 Share Posted June 18, 2006 Get windows X64, it has no memory limitations, well pretty much, it can utilize 128 GB of physical ram and like 8 TB of virtual ram... Just make sure that all of your equiptment has 64bit drivers before making the switch, that's what I did, and I've never been happier... Link to comment Share on other sites More sharing options...
Elliot Posted June 18, 2006 Author Share Posted June 18, 2006 William It sounds interesting. Will my applications run under the 64bit? Thanks Elliot Link to comment Share on other sites More sharing options...

Upgrading to X64 doesn't mean you'll be able to use all 8gb of your ram : ( ...A-desk to get off thier asses and make 64bit versions of Max/Viz before we can enjoy the multi-gig ram glory we are dreaming of Link to comment Share on other sites More sharing options...

Thanks Elliot Yes they will, they will utilize your 4 gigs, that's how much you have right ? And I'm sure the next versions of max, viz and maya are going to be 64 bit, let me put it this way...they better be !!! so you'll be ready to go...

The problem now is that we have seriously out-paced the processor, it can't process hundreds of gigs of info, even if the memory can hold it, I mean in a reasonable amount of time...but they will eventually catch up...

bavanor Posted June 19, 2006 Share Posted June 19, 2006 Has anyone tried to do a two OS boot system, one for Win XP and the other Win X64? Would that be a way to work around the software not ready for x64? I am curious about this because I will be in this situation soon, more RAM than xp can handle.

You can certainly dual boot both, but if your worried about some software not working, I think there are only a few, some antivirus software and zbrush come to mind right away, nearly all 32bit software will work, and work better with x64... exactly what software concerns you...

I am worried about software I use for photography, photoshop, InDesign, photo mechanic, portfolio, raw shooter premium, acrobat, etc. I also use ADT 2005, Viz 2005, and sketch UP. And plan on using 3d Max, Maya, XSI, Cinema 4d, or Lightwave in the future (haven't picked the program to use yet). Aaron Link to comment Share on other sites More sharing options...
manta Posted June 20, 2006 Share Posted June 20, 2006 I use pretty much all adobe software and don't have any issues, can't speak for the rest of the photo software, you can just e-mail them and ask whether or not there are any issues, I doubt there will be unless its really old software, as for 3DS Max and Maya they work great, XSI, Lightwave and C4D are already 64bit programs... If anyone is having doubts just download the Demo from Microsoft, give it a try its good for 180 days... Link to comment Share on other sites More sharing options...
Elliot Posted June 20, 2006 Author Share Posted June 20, 2006 William Is the 64 bit Windows for sale or is it a beta type program....? What has started me on all these issues about windows is a Premier movie I am fine tunning with After Effect. The problem is related to memory problems. With the 3gb switch it works a little bit better. Upon using the /PAE and /NUMA switches it also works a little bit better but I have the feeling that if I switch to the Windows 64 my problems could be over. I am planing to upgrade the motherboard with two new Opetron Dual Core and use the Windows 64. Thanks Elliot Link to comment Share on other sites More sharing options...
manta Posted June 20, 2006 Share Posted June 20, 2006 Its been released as OEM software, there is no retail version, I think you can trade in your XP licence (retail not OEM) and they will send it to you or you're supposed to buy it already installed on a computer, but I bought my copy at newegg.com for $134.00... The only thing I should warn you about is its upgrade path, I've read that you won't be able to upgrade to vista, whether or not that will become a fact remains to be seen, My thinking was it was going to be a while before I would upgrade to vista anyway,(I used win 2000 for a very long time after XP was released), so for me, I'll be using X64 for at least a couple years, probably when they've released SP1 for vista, I want to take advantage of 64bit now... Well it should help, you'll get a 4Gig workspace for each program that is not 64bit, until adobe gets around to coding their apps for 64bit...
