32 bit vs 64 bit confusion

I have been using CS4 extended for a few months on a Vista 64 bit machine and recently discovered that the installer installs both 32 & 64 bit versions.
I assumed that the system would automatically run the 64 bit version. I have just discovered after installing a new 64 bit plugin and not finding it that I have been apparently using the 32 bit version all along.My confusion mainly comes from the fact that the plugin installed in the 32 bit version and not in the 64, but it looks like all my custom actions are in both versions, and my custom workspace is in both. Does PS automatically put a copy of a new action and workspace in both versions, and the plugin installer only put it in one? TIA

Thanks John. I had looked at the help>about Photoshop menu, but not system.
Re icons-I guess I told the installer not to make shortcuts, or I might have eliminated one.
(I have run both versions just now by double-clicking on them in their respective folders)
Two more questions:
1) Will creating an action in one version place a copy of it in the other version?
Edited: Zeno answered this while I was typing-Thanks Zeno
2) It seems that there are several questions on this forum about problems with the 64 bit version.
Would one be more prudent by sticking with the 32 bit version? (My largest files rarely exceed
300 mb, and I have a quad processor with 6 gigs of ram.)
Again, TIA

Confusing Performance Results--64-Bit and 32-Bit Geekbench Results

I don't understand all of my results for the performance tests mentioned in my subject. Can anyone help me understand what is going on?
I posted the results given below in an earlier thread. I don't think "we" had quite as good an understanding of the 32-bit kernel mode, the 64-bit kernel mode, and related topics back then. So, I am revisiting my results and looking for explanations. My results contradict some of the things we tend to say.
I have both Geekbench 32-bit and 64-bit. So, I made four quick benchmark passes. The Geekbenck scores from my four passes are given below. Note that the Geekbench programs are Mac universal. That is, they are made to run on both Intels and PowerPCs and apparently having started up in either the 32-bit or the 64-bit kernel mode. In general, such programs are not designed to run as either 32-bit or 64-bit. Doing so is not the same thing as simply running having started up in either the 32-bit or the 64-bit kernel mode)
64-bit SL/64-bit Geekbench--4,263
64-bit SL/32-bit Geekbench--3,910
32-bit SL/64-bit Geekbench--4,159
32-bit SL/32-bit Geekbench--3,809
These results suggest that:
1. 64-bit programs are faster than 32-bit programs whether run in 64-bit or 32-bit mode (sort of understandable--Incremental RAM is available under 64-bit mode, but should the difference be this large?);
2. There is a performance penalty for running 64-bit programs in 32-bit mode (not understandable--64 bit programs are supposed to run essentially the same whether run under the 32-bit kernel or the 64-bit kernel); and
3. 32-bit programs run faster in 64-bit mode than in 32-bit mode (not understandable--32 bit programs are supposed to run essentially the same whether run under the 32-bit kernel or the 64-bit kernel).

Who is "we" in this?
I didn't take names, ranks, and serial numbers.
but it isn't as simple as one kernel outperforming the other. There are (fairly) well known tradeoffs in using the 64-bit kernel ("K64" in Apple jargon), the most significant of which for most users being loss of 32-bit driver support. There are also some concerns about the stability of the combination of available 64-bit drivers (including Apple's) & K64 on some of the >Macs that Apple "artificially" excludes from booting with K64.
Right, but these things are not pertinent to my tests. But, "we" also say those things.
I don't think anybody understands it all (I certainly don't!) but that's the >point: there really is no "we" in this.
As said, I didn't take names, ranks, and serial numbers of the "we" I referred to--those maintaining that there should not be performance differences of the types I have found and emphasized if 2 and 3 above.
Regarding your GeekBench results in particular, I'm still not sure what you find contradictory about them. 64 bit apps are more efficient than 32 bit ones. The 64 bit CPU instructions available with K64 are much more efficient at some > >things than their 32 bit counterparts.
OK, so then we should expect the sorts of performance differences I found, right? And, you agree that the performances differences I am emphasizing make sense, right? And, you would also agree that, barring need to use apps that won't run in 64-bit mode, those seeking maximum performance should start in 64-bit mode, right? You must not have been part of the original "we." But, now, you, I, and apparently others belong to a different "we"--the "we" that knows that such performance differences should be expected in the context of certain tasks (i.e., the important class of memory and CPU intensive tasks emphasized by Geekbench).
Because GeekBench isolates CPU & memory performance, it is going to be very sensitive to this. But that doesn't mean anyone should expect to see similar results for a practical application or base the choice (if they have it) of >using K64 with their Macs on this or any other benchmark results.
Right on the first sentence, but, importantly, my test isolates bit environment. Otherwise, can't we just stick with the issues raised in my post. I have never claimed we should expect or do the things you mentioned at this time. Further testing of apps and tasks, however, might imply the opposite. But, in general, you are battling mightily against a strawman that doesn't resemble me. I have acknowledged the issues you raise, in effect, as far back as my first post--not in your exact words, but at least implied.
IOW, one size does not fit all.
Why preach to the choir?

ITunes 64-bit runs 32-bit, Secure link to iTunes Store failed, and SyncMapiInterfaceHelper_x64 crashes every time I click 'Info' tab in an iDevice.

Hello everyone,
There are 3 issues I have, as it reads in the title.
1) I am running iTunes on a Win7 64-bit ThinkPad, and iTunes shows up as a 32-bit application in the Task Manager, always. I tried even the complete uninstalling (after removing Bonjour, Apple Mobile Service, deleting the folders, etc.) and yet, it shows up the same way.
2) When I run diagnostics, it says 'Secure link to iTunes Store failed'. I've tried many things from whatever I've read in the forums and nothing seems to be changing that.
3) Every time I click the 'Info' tab on any iDevice (I tried it with a 3GS and a iPod Touch), I get a 'SyncMapiInterfaceHelper_x64 has stopped working' message thrice. I don't know the significance of thrice but it just does come.
I hope someone helps.
Thanks!

That one's normal. On 64-bit systems, iTunes is a mix of 32-bit and 64-bit componentry. The itunes.exe is 32-bit.
Oh, okay. Thanks!
Could you walk us through what happens when you try to connect to the Store, please?
The issue is when I run diagnostics. I happened to run it last night while updating my 3GS to iOS 6, and there was a 3194, and a search to solve that, led me to running the diagnostic.
I was wondering how it affects me because I haven't faced any issue in downloading or browsing the AppStore. The transcript of the 'Run diagnostics', for networks is as below:

Migration from 32-bit to 64-bit on Oracle 9.2.0.5

Hi guys.
I have two question for migration 32 bit to 64 (x86_64) bits on Oracle 9.2.0.5 for SAP 4.7 Enterprise?
1.- When i migrated 32 bits to 64 (x86_64) bits is necesary migrated to Oracle 10 ?
In the note SAP Note 960769 - Windows: Migration from 32-bit to 64-bit (x86_64), say that, pag 4:
" Oracle:
=====================================
On Windows Server 2003 X86_64 (64-bit), you may only use Oracle 10g Release 2 (10.2) software for X86_64 (64-bit) as a database. Note 949116 describes the installation (homogenous system copy) of old products that were not originally released on Oracle 10g Release 2 (10.2). If you want to make the copy using the backup/restore procedure, for which the source database was not yet upgraded to Oracle 10.2, see Note 932722"
But, in the pam matrix say that support for 9.2.
I confused for the information.
2.- In the case that is not necessary to migrate to oracle 10, i can execute the migration to 64 bits the SAP 4.7 with the procedure Backup/Restore?
I don´t have the new server, the server for the migration is the same. The procedure you want to follow is:
1.- Backup Offline all server.
2.- Delete the server, i install the server on Windows 2003 64 bits.
3.- Install SAP 4.7 on kernel 64 bits.
4.- Restore de backup offline (only data): datafiles, archive log, redo log.
Aprecciated for the help.
Best regards,
Desiré

Hi,
According to Note:814834
#Note that there is currently no 64-bit support for the x86_64 platform
for Oracle 9.2 because Oracle does not provide a 64-bit DB client for this purpose,
and, in addition, 64-bit operation of the DB server is not supported.
This means that this DB version can only be used in conjunction with SAP components on
Windows 32-bit on x86_64 hardware in 32-bit mode.
For more information, refer to the "Oracle" section in the note.
Furthermore, it states 32bit SAP instance can connect ot a 32 bit Oracle 9.2 or 10.2 database instance.
So for your case, its better to upgrade your current database to Oracle 10.2 and then proceed with migration.

Best practice for managing a Windows 7 deployment with both 32-bit and 64-bit?

What is the best practice for creating and organizing deployment shares in MDT for a Windows 7 deployment that has mostly 32-bit computers, but a few 64-bit computers as well? Is it better to create a single deployment share for Windows 7 and include both
versions, or is it better to create two separate deployment shares? And what about 32-bit and 64-bit versions of applications?
I'm currently leaning towards creating two separate deployment shares, just so that I don't have to keep typing (x86) and (x64) for every application I import, as well as making it easier when choosing applications in the Lite Touch installation. But I know
each deployment share has the option to create both an x86 and x64 boot image, so that's why I am confused.

Supporting two task sequences is way easier than supporting two shares. Two shares means two boot media, or maintaining a method of directing the user to one or the other. Everything needs to be imported or configured twice. Not to mention doubling storage
space. MDT is designed to have multiple task sequences, why wouldn't you use them?
Supporting multiple task sequences can be a pain, but not bad once you get a system. Supporting app installs intelligently is a large part of that. We have one folder per app install, with a wrapper vbscript that handles OS detection. If there are separate
binaries, they are placed in x86 and x64 subfolders. Everything runs from one folder via the same command, "cscript install.vbs". So, import once, assign once, and forget it. Its the same install package we use for Altiris, and we'll be using a Powershell
version of it when we fully migrate to SCCM.
Others handle x86 and x64 apps separately, and use the MDT app details to select what platform the app is meant for. I've done that, but we have a template for the vbscript wrapper and its a standard process, I believe its easier. YMMV.
Once you get your apps into MDT, create bundles. Core build bundle, core deploy bundle, Laptop deploy bundle, etcetera. Now you don't have to assign twenty apps to both task sequences, just one bundle. When you replace one app in the bundle, all TS'es are
updated automatically. Its kind of the same mentality as active directory. Users, groups and resources = apps, bundles and task sequences.
If you have separate build and deploy shares in your lab, great. If not, separate your apps into build and deploy folders in your lab MDT share. Use a selection profile to upload only your deploy side to production. In fact I separate everything (except
drivers) into Build and deploy folders on my lab server. Don't mix build and deploy, and don't mix Lab/QA and production. I also keep a "Retired" folder. When I replace an app, TS, OS, etcetera, I move it to the retired folder and append "RETIRED - " to the
front of it so I can instantly spot it if it happens to show up somewhere it shouldn't.
To me, the biggest "weakness" of MDT is its flexibility. There's literally a dozen different ways to do everything, and there's no fences to keep you on the path. If you don't create some sort of organization for yourself, its very easy to get lost as things
get complicated. Tossing everything into one giant bucket will have you pulling your hair out.

Oracle Homes 32 bit or 64 bit ?

Hello All,
I am working on Sun Solaris Sparc 64 bit system, EBS R12.1.3.
When i have to apply apps patches, we are going with 32 bit patches. Even when we upgraded java we used 32 bit java.
Now, I have to apply some opatches to 10.1.2 and 10.1.3 Oracle Home respectively, so do i have to download 32 bit or 64 bit patches?
Please suggest!
Thanks,
Moor

why do we have this confusion, when we are on 64 bit OS and have installed 64 bit EBS software, why we are going with 32bit apps patches?
If you have EBS 64-bit running on 64-bit OS you should always look for the 64-bit patches. If the 64-bit patches are not available while 32-bit patches are then you can safely download and apply the latter.
Please see the solution section (Can the 64 bit version of patch 8888184 be applied to a 32 bit OS? (Doc ID 1054058.1)) for more explanation.
Thanks,
Hussein

8 bit vs 16 bit

I started creating photo books, and I've been running into some confusing territory. So far my procedure has been to edit RAW photos in Lightroom, then export 16 bit PSDs to InDesign. I layout the whole book in Indesign. Then I have to make PDFs of the book and convert everything to JPGs.
My confusion centers around 8 bit vs 16 bit. If I am converting to final JPGS, should I export as 8 bit right out of Lightroom? Or is it better to stay away from 8 bit as long as possible?

Nice suggestion, but it will generate BIG files though of you use Smart Objects.
For 99% of most publishing needs you won't need 16 bit files. certainly not if you are placing them directly into Indesign, and then exporting them anyway as 8 bit jpegs for print.
16 bit files are for EDITING. They are useful for many color corrections back and forth, for pushing and pulling with 10 retouchers all arsing with the file, to avoid DAMAGE and posterisation. For most printing needs you have to do A LOT of damage to an 8 bit file before that damage registers on the print. Like the ******** I worked with for 3 years who would pile 50 adjustment layers on top of an 8 bit image and wonder why the resulting injet looked like a rainbow - thats what you would be trying to avoid.

10R2 installer 64-bit or 32-bit?

Hi all,
I have some doubts here. I have an installation DVD for Oracle Database 10g R2 for HP-UX Itanium, but I am not sure if it is for 64-bit or 32-bit; it's not printed on the DVD.
I also went to the 10g download page on OTN, again it is not mentioned, not like some other platforms like Linux, Solaris and Windows. I have also checked on 9i download page and on the contrary, there are two links for both HP-UX 32-bit and 64-bit.
How should I set my assumptions? Should it be 32-bit unless mention explicitly for 64-bit. To be installed on an HP-UX Itanium IA64 (64-bit). There are also Itanium 32-bit, but I am not sure if they are quite new and Oracle did not have the installer for the architecture. Kind of confused here.
Please assist, and thanks in advance.
Regards.

You can check platforms and certification on MetaLink if you have a support contract or also at [https://metalink.oracle.com/metalink/certify/certify.istore_welcome]
For example, if I navigate through the selection screens for Platform- HP-UX Itanium and Database/Server, I see
Itanium Information
64-bit Oracle database software only supports 64-bit for Itanium. Oracle does not support running the 32-bit database on Itanium.
and then when I scroll down to the Oracle Database Product Versions selection list I see only 64bit versions of 11g, 10gR2, 10g and 9.2
Thus, there is no 32bit version of Oracle on Itanium and the 64bit version is only for 64bit Itanium.

Can i install a mix of 32-bit and 64-bit package ? and they work together ?

Customer environment is Linux x86-64 having package pam-0.99.6.2-6.el5_4.1.x86_64 installed as per x86-64 server and application requirement.

Question:
So, is there any way we can install the 32 bit version of this ? While 64 bit is still there ?
Concern with installing the 32 bit library, is that something picks it up mistakenly when it expects the 64 bit version.
Edited by: sgaraga on Jun 8, 2012 4:39 PM

You can run 32-bit software under a x86-64 OS provided you install the necessary x86 (32-bit) libraries.
The x86_64 CPU is fully backwards compatible with Intel x86 16-bit and 32-bit code. Because the full x86 16-bit and 32-bit instruction sets remains implemented in hardware without any intervening emulation, existing x86 executables run with no compatibility or performance penalties (http://en.wikipedia.org/wiki/X86-64)
An application that is 32-bit or 64-bit will have to be linked or share the appropriate library. 32-bit and 64-bit libraries won't be confused because they use different names.

32-bit vs 64-bit JVM, JDK, DLL's

I've got a project that has a couple dependencies:
1. My project interacts with an FTDI USB->Serial converter based device. Access to this device is via DLL(FTDI calls them D2XX drivers). FTDI offers both 32-bit and 64-bit drivers. Please see here .
2. In order to get access to the DLL via Java, I'm using a JNI called [jd2xx|http://bleyer.org/jd2xx/] . I don't know if or how a JNI would change if the DLL used is 32-bit or 64-bit.
My build & run environment was XP/32. Now I want to build/run on Vista64. But I'm confused because there are multiple options for downloading and installing the different parts which make up the system:
1. Netbeans is available for 32-bit and 64-bit. Which JVM should I point Netbeans to?
2. JVM comes in 32-bit or 64-bit.
3. JDK comes in 32-bit or 64-bit.
While I don't think anyone else actually uses my project, I'd like to have both XP/32 support and Vista/64 support. If I must go one way or the other, it's gotta be Vista/64.
I have tried multiple combinations, but I get a variety of errors depending on what's installed. The errors are all related to 32-bit/64-bit conflicts.
Can someone point me down the right path?
Thanks
Keith

I searched fairly thoroughly through the NetBeans GUI to see if I could target a particular platform, like 32-bit vs 64-bit ---- and I didn't find one. While it may not matter for java itself, when java interacts with a native dll, there are obviously implications.Java class files are os-agnostic - there isn't a "32-bit version" or a "64-bit version", they're both the same. What is different is the JVM that you run a class file on. A 32-bit JVM requires the appropriate 32-bit libraries, etc; the same requirement exists for a 64-bit JVM. I don't know if you can tell an IDE to run using one JVM or the other (obviously this would be possible only with 64-bit arch). I do know that the java tool for Linux/Solaris allows the use of a -d32 or -d64 option to specify that, and that the options aren't valid for the Windows java tool. I also know that Eclipse has native dependencies due to SWT, so that probably causes some restrictions. And. as you note, doing somethisng like JNI has "implications".
If you have further questions re NB, you should raise then at a NB site, not here.

Nvidia Chipset- 32-bit or 64-bit?

Hi, I am new to these forums, so I apologize if this question is posted already somewhere else- I just can't find an answer, so I'm posting my own question.
Can anyone tell me whether or not the new macbook pros (late 2008) have a 64-bit or 32-bit chipset? I've been reading mixed answers throughout the web, and it seems nvidia and apple are being pretty quiet about the answer.
I know that right now this question doesn't really make a whole lot of difference, I just want to make sure that when snow leopard (and nehalem for that matter) is released i'm not kicking myself TOO hard if I decide to take the jump and get the new MBP now.
If anyone knows, I would really appreciate a solid answer. THANKS!

Thanks for the link- I had skimmed through it before, but paid a little more attention to the details this time.
So the article says that there is no 32-bit version of Leopard. What confuses me is that a bunch of sites are stating that the nvidia chipset is only a 32-bit chipset. So I'm still unsure about whether or not the chipset is 32 or 64... I mean,
I'll probably never require more than 4gb or ram (at least for the time being) but I just want to make sure that if I make my MBP purchase now, I will not be really unhappy when Apple releases snow leopard (and 64-bit nvidia mobile chipsets to go along with it). Any advice on interpreting that article and information on the 64-bit status of the current mbp chipset is appreciated.
Thanks Again. (I guess I'm just trying to justify buying now, instead of waiting for nehalem... it's a tough task)

Upgrade Roadmap for Windows/Oracle/SAP from 32 bit to 64 bit

Hello,
what steps do I have to perform when upgrading the following system:
SOURCE:
- OS Windows 2000 32 bit
- Oracle 8.1.6 32 bit
- SAP 46C 32 bit (46D Kernel)
TARGET:
- OS Windows 2003 64 bit
- Oracle 10.2 64 bit
- SAP ERP 2004 64 bit
In which sequence do I have to perform what steps?
First the OS, then the DB, then the SAP?
or something else?
Thanks for any help,
Michael

Hi Michael
Sorry to open your old thread.
Would you mind sharing your upgrade experience on 32 bit to 64 bit?
We are planning to upgrade our CRM 4.0 (Oracle 10g + Windows 2003 32 bit)
Source:
CRM 4.0 (Web AS 620 + 640 kernel)
Java 620
Windows 32 bit
Oracle 10g
Target
CRM 4.0 (Web AS 620 + 640 kernel)
Java 620
Windows 64 bit
Oracle 10g
I am bit confused about installing SAP CRM on Windows 64 bit software. I understand that you install SAP using 640 kernel for 64 bit.
I would appreciate if you can share your experience or the procedure followed.
After the 64 bit migration is completed, we will be upgrading our CRM 4.0 to CRM 2007.

32 bit to 64 bit upgrade in Windows x86_64 on Oracle

Please suggest an approach for 32 bit to 64 bit migration on Windows/Oracle combination 9i.
PAM indicates that, Oracle runs in 64bit mode only in 10g version
This would require an oracle upgrade.
Please suggest an approach when your database size is huge.

Hi Markus,
Let me cleary explain the sceanrio,
I have a Sandbox 4.6C , Oracle 9.2.0.8 with Windows 2003 Server on 32 bit with over 1 TB of data.
Now i have a brand new x86_64 bit hardware with Windows 2003 Server 64 bit OS install.
I have to use this to make a System Copy of the current Sandbox and upgrade it ECC 6.0.
How do i plan this, it is quite confusing???
There are two things here
a) 32 bit to 64 bit migration
b) Oracle 10g upgrade
Plan a)
Make an Export of the current 9i 32 bit database , fresh install of Oracle 10g 64 bit on the new 64 bit server and import the whole data
But the only problem is huge data to export.
Plan b)
Make a homogeneous sytem copy since it is Windows 32 bit to Windows 64 bit and then upgrade to Oracle 10g. This requires me to install Oracle 32 bit 9i on a 64 bit hardware, is it SAP recommended??
How do i do this??

Differentiate 32 bit and 64 bit

Hi Guyz,
How do we know the SAP we are using is 32 bit or 64 bit?
I am not able to find out this information from the Status.I am planning for a Kernal upgrade for ECC6 and confused which(32 bit or 64 bit) Kernal to use.
Warm Regards,
Syam

Dear Syam,
Please do refer to the note given by Manu . It is actually very old and not updated, but has generic command like once you navigate to exe\run (or a similar path to mine) of your server using command line/ command prompt, you can use disp+work.exe -version etc. In fact I will quote the whole section from it - Point - 12 - please note some of them might be outdated.
12. How can you find out whether an object is installed in its 32-bit or 64-bit version?
a) R/3 executables (R3trans, Kernel, tp, R3load):
                       cd /usr/sap/<SID>/SYS/exe/run
disp+work -version
R3trans -version
etc.
If no bit-version is mentioned within the text, this means it is a 32-bit version. 64-bit version would return something like       .... COMPILED WITH 64-BIT LIBRARIES....
b) Oracle
                       as ora<SID> user start svrmgrl
In the header it shows oracle-version and bit-number.
you can also do a SELECT * FROM V$VERSION;
                       Oracle client-lib
library oracle is using CD $ORACLE_HOME/LIB
FILE LIBCLNTSH.<EXT>libary the R3-tools are using
Please check note 180430 for your R3 release specific oracle client note. The location of the clientshared library has changed with different R3 releases. Get the location of the library from that note and then execute:
cd <directory where the clientlib is in>
FILE libclntsh<version>.<extension>
Most kernels also have the function calls to the oracle libraries extracted to a new library dboraslib.<extension> Please also check this library:
cd /usr/sap/<SID>/SYS/exe/run
FILE dboraslib.<extension>
c) OS
HP:
getconf KERNEL_BITS executed as root user returns either 32 or 64
DEC-UNIX:
automatically 64-bit - also shows with the command /usr/sbin/sizer -v
AIX:
beginning with release 4.3.1 64-bit; please make sure that all hardware components are 64-bit. When installing 4.3.1 AIX automatically detects whether your hardware is 64-bit and will install the necessary 64-bit software components. The easiest way to find out whether AIX is 64-bit is by the following commands:
lslpp -l bos.64bit - this should return a line that bos.64bit is installed
genkex | grep 64    - this checks whether the 64-bit kernel extension is installed. it should return something like
149bf58 a3ec /usr/lib/drivers/syscalls64.ext.

Web design 8 bit or 32 bit colors?

Hi
I just wanted to know if i were to design a site in 8 bit, would i be able to easily convert to 32 bit colors? Or if it was a 32 bit psd, what would the color difference be to the naked eye if i "downgrade" it to 8 bit through photoshop settings?
I'm just worried that if the client has 32bit colors images, then it wouldnt be able to look as good if i place them in my 8bit file.
One of the client's requirements for this web project is 32 bit colors. So i'm really kinda stumped on this. 32 bit is running too slow on my computer.
Besides what i've understand from searching online is that it applies more for photos?
Can someone advise me?
Thank you very much in advance.

There's confusion over the definition of terms here.
When referring to the bit depth of an image, it's usually stated in "bits per channel" (bpc)
8 bits = 8bpc
16 bits = 16bpc
32 bits = 32bpc
For an RGB image, 8bpc would yield a 24 bit image (8bpc X 3 channels)
For a CMYK image, 8bpc would yield a 32 bit image (8bpc X 4 channels)
I would guess your client is asking for 8bpc images. Their confusion comes from hearing that CMYK images are 32 bit files. (I'd venture to say that they work a lot with CMYK...)
Al images bound for the internet should be 8bpc.
The only current use for 32bpc files is HDR.
Engage in a little client education. They'll appreciate it.
Hope that helps.

32 bit vs 64 bit on my macbook?

hello
i have a macbook 2.16GHz core 2 duo with a 250gb HDDand a 3gb RAM.
i am really confused with the upcoming leopard's 32 bit and 64 bit stuff. sorry for such ignorance.
but will my present macbook be having problems running leopard in the future?
will my macbook support the 64 bit thing?
thanks.

Hello,
I would really like to know if Leopard -definitely- will run on Core "1" Duo. Apple is not giving hints that make me feel optimistic about it ("only one 64-bit version" - I don't know any 64-bit OS running on 32-bit arch).
On the other hand, I've been told that there are developers using Leopard builds on Macbooks RevA...
