even though the max for photoshop is 2g, it would still help to have more, becasue OS takes a helthy chunk, plus anything else you might have open.
I have 3 gig ddr and 1.7 of that is for PS, the rest for nulti taksing. everything flyts along.
The simple answer is: more!
*If* you have a 64-bit processor (AMD64/Intel EM64T), consider switching to Windows XP 64 Bit Edition when released. On that combination, Photoshop CS2 can use 4GB of address space.
In addition (!!!) if Photoshop CS2 sees more memory than that in the machine, it uses it’s scratch file in a slightly different way that allows the operating system to cache the scratch file in the additional RAM. A machine with 6GB of memory will, in fact, see measurable performance increases over a 4GB machine.

Hello everybody
I would just like to find out what is the maximum amount of memory supported by CS2 under Windows XP Pro.
I have 2G on my present machine because that is the maximum supported by CS. I am just trying to ready the computer for the upgrade.
Thank you all in advance.

monday (tomorrow!)!!! according to slashdot and zdnet.

Outstanding…
The PSNews article refers to the "3 gig boot switch" as the way to utilize up to 3GB of RAM in Win XP SP2. Anybody know more about this?
Thanks, all. Now I have to read and understand. <g>
It will be interesting to hear from anyone who has successfully used the 3GB boot switch with PS CS2…
Microsoft is actually offering FREE upgrades to WinXP Pro x64 for users who have 64-bit capable AMD and Intel CPUs. According to the report I read, all you have to pay is shipping costs for the CD.
But BEWARE. You will lose your license to run the standard WinXP OS. That’s an important factor because there is a lot of compatibility issues with jumping to 64-bit. Older legacy apps using 16-bit installers will not work. Many periphreal drivers will have to be recompiled for 64-bit code to work. This upgrade is not for the faint of heart.
There’s a number of articles about WinXP Pro x64 at various computer trade magazine websites. Read up on it if you’re not already familiar with the installation issues.
The upgrade for WinXP Pro x64 will not be available on retail store shelves. Microsoft did not want anyone to just casually pick up this OS and install it without knowing the possible consequences. The new OS will also be available as an OEM item for new computers soon.
Cathy, when you figure out how to set the 3G boot switch in XP, let us know. I could not implement what was described in the link Dave posted.
I tried the 3GB switch with XP pro a few months ago, but only succeeded in stopping XP working completely, and eventually had to reinstall from my ASR recovery disks. I’ll wait until someone else says they have a method that works!
Bob Frost.
The 3 GB switch works for me now, and PS is seeing and using 2.8? GB of RAM. There are 6 GB in the machine.
This is on XP pro 32bit.
64bit sounds like a horror show at this point. Almost worth it to buy an extra copy of the 32bit OS to maybe dual boot?
Quale, if you are feeling brave, open the file boot.ini from the root level of your c drive in notepad or wordpad (it must be text only!). Maybe back it up first to reduce sweating.
here is a cut and paste of the last line in my file:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect /3GB
maybe someone who knows more could explain better/more clearly/correctly? Not a geek here, thought I would like to be.

Yes, according MS you are entitled to free upgrade to XP x64 if you bought 64-bit compatible computer with PREINSTALLED version of XP pro (32-bit). That takes care of self built systems, with self installed (retail version) of XP pro. <G>
But BEWARE. You will lose your license to run the standard WinXP OS
Exactly, who in their right mind would give up XP pro (32-bit) license for XP 64-bit (with questionable drivers support) without ability to dual boot?
Im confused with this MS offer. I want to buy XP 64-bit (and keep my 32-bit license) but this doesnt seem possible at this time.
Apparently the only flavours of XP64 are ‘Upgrade’ (free) and ‘OEM’.
So I suppose you could purchase a new hard drive with XP64 installed? That way you’d preserve the dual boot option.

My local computer shop tells me they’ve had a document from Microsoft stating their OEM policy:
Full retail product may be moved from machine to machine.
OEM product ‘lives and dies’ with that particular PC.
This presumably means that once happy with your new 64 bit OS (which you paid for), you can’t then move your XP32 (which you paid for) onto another computer!? <big_frown>
It also begs another question: What if your mother board fried? Would MicroNotSoSoft turn around and refuse activation on your new motherboard? <shudder>

In my case, they did not. I recently built a new box from the ground up, installed the OEM version of XP Pro (that came on the old box), and had to reactivate with MS. All they asked was why. I explained it to them and they reactivated me. (I’m assuming they could tell it was an OEM version from the numbers that I gave them.)

That’s encouraging.
Actually MS is very good about activation. I had to re-set a clients system with an OEM, not once, but several times because of bad ram. I explained the problem and they said ‘cool, rock with this’ and the client is now skippy all over. Would hope so with a $4000 (Cdn) investment.

Exactly, Andrew. Seems like they’re saying that 64bit is free, but you’ll have to buy another copy of 32 bit.
But where did you see that bit about self-built computers with retail XP not being eligible for the exchange?
Microsoft says:
The Windows XP Professional x64 Edition Technology Advancement Program enables customers who have purchased Windows XP Professional (32-bit) to exchange it for Windows XP Professional x64 Edition. You will need to have an x64 processor (the AMD Athlon 64, AMD Opteron, Intel Pentium 4 with EM64T, or Intel Xeon with EM64T) to run the new software.
I don’t see any exclusions there.
There are 2 IMHO important milestones ahead – 3 including PSCS2
This year is 10th anniversary of Windows 95 and next year is 30th anniversary of Microsoft – I expect great things
Cathy,
But where did you see that bit about self-built computers with retail XP not being eligible for the exchange?
From MS website:
"Technology Advancement Program Eligibility
In order to be eligible to receive Windows® XP Professional x64 Edition, your computer must have been ordered between March 31, 2003 and July 31, 2005 with Microsoft Windows® XP Pro (32 Bit) preinstalled."
Oops! You’re right, Andrew. I missed that bit of small print.
Curiouser and curiouser. Seems like they don’t want home tinkerers to get their hands on the app, since they won’t be offering a retail version.
I wonder if OEM copies will be available for purchase?
I expect great things
me too. just not from microsloth. 🙂
Cathy,

Yes, check your favorite parts suppliers website. 😉
