I’m running Photoshop CS on a Fujitsu CELSIUS 670 Workstation, with double Xeon 2Ghz, 3Gb RAM RIMM ECC, 2 SCSI Ultra160 Controllers using the Scratch Disk on Raid0 and a nVidia Quadro 4 Graphic Card with 128Mb.
After open Photshop CS I have 2733Mb free on the system, but on Photoshop preferences even if I use the memory on 100% I can only use 1729Mb, this is really very weired, it looks like 1Gb is lost, but it works on all the other software I have installed. The memory is tested by Fujitsu, and it seems that everything is working. Anyone knows what can I do to solve this problem?

Photoshop can only use 2 gigs of RAM. It’s been discussed elsewhere. And lower that 100% to around 50%.

Why 2 gigs of RAM?? this is very weired, is photoshop made for Windows XP Home? Is there any way to have Photoshop full compatible with XP Pro features. Since I bought CS I already had problems with Multiprocessors, now the memory is limited, this is starting to look like Photoshop is a home user software with a Pro prices. This is a shame.

The 2BG limit is a limit of both Windows XP Pro and Windows XP Home, not a limit of Photoshop CS.

XP limits ALL software to 2BG of RAM each.

< http://www.microsoft.com/windowsxp/pro/evaluation/features.m spx> Scalable memory and processor support: Supports up to 4 gigabytes (GB) of RAM and up to two symmetric multiprocessors.

It looks like XP Pro can work up to 4Gb. By the way, I have the same problem in CorelDraw 12 that only work with 2055Mb, but the worst case is by far Photoshop that only works with 1729Mb. Photoshop even doesn’t work with 2Gb, works only with 1.7Gb and I can’t remember any other image program that needs so much memory as Photoshop, so why limit it?

Does Windows 2000 have this same limitation?

Thanks

Paulo,

Supports up to 4 gigabytes (GB) of RAM <<

It does BUT applications cannot use more than 2 gigs. The additional will help when running multiple applications, but not when running any single application.

Photoshop even doesn’t work with 2Gb, works only with 1.7Gb<<

That is the memory available for image data. The application itself is using the other 0.3 gigs

So, which windows version should I buy to use more than 2Gb on Phoroshop? XP 64??

I wouldn’t hold my breath waiting for Longhorn. You’ll just have to learn to live with ONLY 2 gigs or RAM being used.

if you don’t have an intel itanium chip, there’s no 64 bit windows. it’s been delayed to 2005.

Th 2GB per process limit is valid for the whole WinNT family – it might be true for other 32bit OSs too (AFAIK: OS X…).

Each application can use a 2GB adress space, in the server edition it is possible to arrange for 1GB system/3 GB application for applications that are aware of that option – th means: Not Photoshop.

Address space…

I’d guess that no version of Desktop Windows will be able to use more than 2 GB per process this year.

And even if Windows could, you have to wait for a 64bit Photoshop application.

Just accept that 2 GB is tha limit for (at least) the next 12 months.

My Windows XP Pro is now completly configured to run applications with 3Gb, after all I just had to put a /3GB command on boot.ini it’s working fine in all application. The funny thing is… Photoshop doesn’t run sometimes, and when it runs it’s still using 1.7GB, so as I can see it’s a CS and not a XP limitation.
It’s hard to learn to live with ONLY 2Gb. 1) I use Photoshop to work with huge images. 2) I payed for CS and all I got was the slowest software I ever used, specially compared with all prior versions. 3) I’m still wasting money trying to tune CS to work with this huge images. 4) ONLY 2Gb could be a lot for some user and a small amount to others, it depends on the kind of work.
I wonder what would be the ideal system to work with CS with the same performance of Photoshop 7 on an usual system.

To be perfectly honest with you, when I have to work with large images, I use 7.0. I find CS way too sluggish with anything over 200 megabytes on my system. P4 2.8 with ONLY 1 gig of RAM.

As far as I know, not all programs support the /3GB switch. Unfortunately Photoshop seems to be one of them.

Executables that | can use the 3 GB address space are required to have the bit | IMAGE_FILE_LARGE_ADDRESS_AWARE set in their image header. If | you are the developer of the executable, you can specify a | linker flag:
|
| /LARGEADDRESSAWARE
|
| "To set this bit, you must use Microsoft Visual Studio Version | 6.0 or later and the Editbin.exe utility, which has the | ability to modify the image header (/LARGEADDRESSAWARE) flag. | For more information on setting this flag, see the Microsoft | Visual Studio documentation."

photoshop does not support the /3gb switch (per the developers), as it’s not officially supported by microsloth.

I expect to see an official release of PS for 64 bit soon after MS releases an official (shipping, not beta) 64-bit operating system.

I wonder what would be the ideal system to work with CS with the same performance of Photoshop 7 on an usual system.

my system runs cs as fast or faster than 7. p4 2.8c 400mhz fsb, 1 gig pc3200 ram. it’s all in the tuning. see the faq:

I am running 7.0 on my machine although we do have CS in the office.

My workstation: < http://www.customperfect.com/Base-Models/GraphicDesigner/cle arcase/>

I have 2 gigs of memory total (and I thought I had a LOT of memory!) but I seem to have more available than you (1879 available) when I am running PS 7.0

Do you think that is because I have 7.0 or is it because of the way the guys at customperfection configured my machine? (They say they optimized it for Photoshop).

I have to ask you though, what kind of images are you using where you need sooooooo much memory? I’m really curious.

Photoshop is the BEST photo editing software available on PC or MAC, so if you can’t do what you want with Adobe’s Photoshop, you wont be able to do it. No other software even comes close.

partly

or is it because of the way the guys at customperfection configured my machine?

doubtful. more likely some ram savings is due to differences in installed plugins.

MHz

Abbreviation for megahertz. One MHz represents one million cycles per second. The speed of microprocessors, called the clock speed, is measured in megahertz. For example, a microprocessor that runs at 200 MHz executes 200 million cycles per second. Each computer instruction requires a fixed number of cycles, so the clock speed determines how many instructions per second the microprocessor can execute. To a large degree, this controls how powerful the microprocessor is. Another chief factor in determining a microprocessor’s power is its data width (that is, how many bits it can manipulate at one time).
In addition to microprocessors, the speeds of buses and interfaces are also measured in MHz.

How disappointing! I just built a computer with 4 GB of fast RAM so I could handle the 2.25 GB files I can make scanning 4×5 colour negatives using all the optical resolution of my Epson 4870 at 16 bit.

Spent a lot of money for that RAM, too…
