Upgrading from 4GB to 12GB slot question

Hi. I searched a bit, but didn't find a quick answer.
I have a late 09 iMac with 4GB (2x2) installed. I just bought two 4GB sticks on OWC for $239 and they're on the way.
My question is this: Would it make any difference at all if I put these two memory modules in the 3 and 4 slots -- or would I gain any benefit from putting them in slots 1 and 2 and moving the smaller modules to 3 and 4.
Thanks for your advice.

Hi,
to my knowledge there is no benefit to moving the old modules before installing the new ones.
No speed-gain in doing so.

According to this,
http://www.everymac.com/systems/apple/imac/specs/imac-core-2-duo-3.06-21-inch-al uminum-late-2009-specs.html
which is the oldest 21.5 inch iMac I could find, this model came with 4 GB standard RAM and can be upgraded to 16 GB.
Whether you will notice a difference depends on what you use the computer for. If you use programs like Adobe Photoshop, MS-Office, or have many photos and lots of music in iphoto and itunes, you would see a noticeable improvement. Also, if you keep a lot of software running at once, there will be a very big improvement in speed and responsiveness.

Upgrade from CS2 to CS5 multi-questions

A few questions actually..
I very recently just bought an upgrade from Photoshop CS2 to CS5. Everything went well but I don't understand a few, possibly trivial, things.
During the installation process, I in no way had to supply information about my CS2 licence to prove that I even have it. How do you guys make sure that someone who doesn't own a previous version of Photoshop isn't saying that they want an upgrade, thus avoiding the full price of the product?
Also, when you upgrade, does your old previous version license become deactivated? Are you suppossed to remove it from your computer or some other process?
Lastly, when I downloaded the upgrade, I downloaded both CS5 for 32 and 64 bit by default as they were both there. Do I need both on my computer and what's the difference between using/having the two?
I'm running Windows 7 Home Premium 64 bit to clarify.
Thanks in advance!

If you purchased and upgrade then it should ask for a qualifying serial number. It is also possible you purchased an upsell which means you were basically given a copy of the full version at a discounted price. The qualification process is done when you purchase the software.
You can continue to use your CS2 license. You can not however sell it as it is qualifying you to utilize CS5.
For questions about 64-bit I would recommend reviewing http://blogs.adobe.com/scottbyer/2006/12/64_bitswhen.html

Win2k3 RAM upgradation from 4GB to 16GB

Hi,
Can we upgrade RAM from 4GB to 16GB in windows 2003 SP2 (32 bit) standard edition, by enabling PAE?
This is VM and hosted on 4.1 esxi.

See the link below but basically no. If your running 2003 SP2 Standard then its only 4GB limit. If your on Server 2003 Enterprise then you can go higher.

Is there a point to upgrade from 4GB to 8GB?

Hi
I have a MacBook Pro Intel Core 2 Duo 2.4 GHz with 4GB memory (2010).
I want to upgrade my hard drive from 250(5400rpm) to a 500GB or bigger (7200rpm).
So I'm thinking since I'm already upgrading, should I get more memory?
I find it sluggish at times, but I've been blaming the hard drive for the most part.
But I'm wondering if doubling my memory would make an even bigger impact on the performance?
I will be doing some Final Cut at some point and video converting, so I'm wondering if the extra memory would be worth it?
*Yes I know it's a small machine for Final Cut. But I had a Mac Pro until I quite my job, so buying it I never thought I would need more power :-S
Anyway, let me know what you think. Thanks.

I would recommend getting a solid state drive rather than a faster hard drive, that would make a far greater difference than upgrading from a 5400RPM HDD to one that spins at 7200RPM and either replace your optical drive with a second hard drive or using an external drive for non-essential storeage. I'd also upgrade the RAM because 2x4GB of DDR3-1066 RAM is super cheap right now, I added 8GB of RAM from Crucial to my 2008 MacBook Unibody for around $80.

Expanding from 4GB to 12GB

I currently have the 21.5" late 2009 iMac model with 2 banks filled with 2GB each of RAM. I am looking to upgrade with 4GB's in each of the remaining two banks.
Is this ok? Or do I need to match the other set?
So my total will be 12GB. 2+2 and 4+4 in the banks

Hi rvenneman,
have a look here for how-to install the memory http://support.apple.com/kb/HT3918
The mightiest task in this is to lift the 27" iMac and put it face-down
And of course the force neccessary to insert the RAM modules
No honestly, it's quite an easy and straightforward thing to do.
Happy computing

Upgrade from CS5.5 to CS6 questions

Why do I have two versions of photoshop now? CS5 and CS6?
The upgrade from CS5 to CS6 didn't replace my older version.
How do I move my actions, plugins, etc to the newer version?
Copy and paste of folders caused runtime errors when I tried to run CS6

The upgrade from CS5 to CS6 didn't replace my older version.
As it should be. Feel free to uninstall CS5.
How do I move my actions, plugins, etc to the newer version?
For actions, brushes, styles etc simply use the flyout menus in the top right corner of the respective palettes. Plug-ins must be properly updated with qualified versions for CS6 as provided by the vendors.

Upgrade from 4GB RAM to 8GB

Hi folks,
This is my first post ever, I would like to say hello from Vienna, AUSTRIA
I need you guys to PLEASE help me out!
As my subject already told, i´d LOVE to upgrade my MacBook Pro Late 2010 with 4GB ram up to 8 GB Ram.
My questions:
1. What is important (Wich RAM chips do i need)?
2. Wich one is the best brand/company? Crossair? Samsung? Kingston? etc?
3. Will I loose my warranty ? If No, 100% sure?
4. Have a good day and thanks in advance
Greetings from cold Austria,
DariBoss

1. What is important (Wich RAM chips do i need)?
You will need 2 x 4.0GB PC8500 DDR3-1066GHz chips. Here is an excellent example:
http://eshop.macsales.com/item/Other%20World%20Computing/8566DDR3S8GP/
2. Wich one is the best brand/company? Crossair? Samsung? Kingston? etc?
As long as the specifications match the answer to Q1 the brand does not matter. Most RAM comes with a lifetime guarantee, I would recommend you double check to see the brand you choose has that.
3. Will I loose my warranty ? If No, 100% sure?
No you won't. The only way you could loose your warranty is to damage your machine when you install it. If you follow the directions in your owners manual and in this video the chances are extremely small you will damage your machine.
4. Have a good day and thanks in advance
You too and your welcome!

CSS Software upgrade from sg0720003 to 8.20 questions

Questions:
1. To go from 7.20.3 to 8.20.x - do I need to go to a intermediate version first.
2. On Cisco Softwrae Sownload site for CSS, I can see 3 files as follows:. Which one do I use to upgrade?
sg0820303.adi

3. Any gotchas / traps to remember before the upgrade.
4. Is the prefered upgrade method - Manual or Automatic - Any advantages / disadvantages of either method?
5. Is there a document with the upgrade procedure only?

Hi,
You need to upgrade to an intermediate version of the software before you can upgrade to 8.20. Acceptable versions are 7.30.4.02, 7.40.2.02 and 7.50.1.03. This is documented in Appendix A of the CSS 8.20 Admin manual - as is the upgrade procedure. AFAIK this is the only document that describes the update process.
For the upgrade you can use either the .adi or .adi.gz file - the CSS will automatically decompress the gzip version if you choose to use it.
Check the Release Notes for any changes to syntax for commands that you use.
I've used the automatic update process - assuming that the script would know what to do. I did make sure that I had backups of the config archived on the CSS and on the FTP server - along with certificates.

Upgrading From Tiger to Snow Leopard Questions

I might upgrade my Mac OS X Tiger 10.4 on my iMac to Snow soon and was wondering if there was a way I could have Snow be on an external drive. I was at my local Apple Specialist store and one of the employees hooked up an external HDD to my computer with I think either Snow or Lion on it. Don't know which. My question is, would it be possible to run Snow on an External HDD while also still having Tiger on my iMac? I like Tiger, and would like to continue using it, but the person told me it would be good to upgrade since my OS is older. I would like to continue using Tiger but at the same time want to use Snow too. So would it be possible to run Snow Leopard on an external HDD while keeping all my files/etc on my Tiger?

If we keep this strictly as a theoretical discussion, the answer is "yes" or "maybe". But I need to explain some context or qualification on that answer in the way I have my system set up.
I set up my system so my home dir is always on its own volume. The boot volume is always separate. That way I can switch to any boot volume and continue to use my same home dir. So if I upgrade my system I can always fall back on the older system or use a backup of the current system if it fails in some way.
Now here's where I qualify that answer. I always recommend never upgrading a system without having backups to fall back on. So, say for example, I go from 10.6.5 to 10.6.6 I always can just boot from my 10.6.5 boot drive for comparison purposes and to revert to it if the update is total disaster. In all cases I am still using my same home dir because it is on a different drive (and of course it has backups too). But these kind of updates are all within the same version of "cat", 10.6.x in this case (all Snow Leopard updates). So that is why I answer "yes".
Going from one "cat" to another is why I say "maybe". So if I update 10.5 to 10.6, or 10.6 to 10.7 IMO, all bets are off. There's no way to know for sure except by trying (which is no big deal since I always have backups). This is due to possible file system changes, finder changes, and who knows what else changes. Hence, "maybe".
If you want to keep two systems with your home dir on those respective systems, of course you can always do that. It's your choice. But then keeping them in sync is a pain. So for this kind of setup it's probably simpler to just bite the bullet and upgrade and use only a single OS.

Upgrading from 3GS to 4, some questions

Hi everyone! I've had the 3GS since January and have been very happy with it, and will be upgrading to the iPhone 4 in a few days for Christmas. Long story short, we will be transferring the 3GS to my sister on her contract and I will be getting the new one, so basically I want to completely reset the 3GS to factory settings. However, I was wondering if it is possible to backup everything on it (ie, games, text message history, contacts, notes, videos, etc.) and then just transfer them over to my newer model come the 25th. I know iTunes has a backup option for the iPhone, I'm just not sure if it will allow me to do this.
So in essence I want my new iPhone to be the exact same as my old one other than the looks and new features. Just wondering if iTunes can automatically do this, or if I will have to look for a third-party program. If so, could you kindly explain to me how I would accomplish this? Thanks guys!

All iTunes content on your iPhone - all music, movies, tv shows, and 3rd party apps should be in your iTunes library on your computer. All photos transferred from your computer should also be available on your computer. No iTunes content and photos transferred from your computer are included with your iPhone's backup.

Upgraded from 4.1 to %, auth questions broke

Hello,
I updated my lighthouse system 4.1 -5.0, (I know we're far behind), and my authentication question functionality broke.
Basically when someone tries to update their auth questions, it either fills them in blank, or a random set of characters is added in the field. Of course we didnt notice this until we rolled out into prod either. Luckily it hasnt been that big of an issue yet.
Any suggestions?

Hi jbyrnes,
Are you still using the gateway for 4.1? If so try to use the gateway for v5. Sometimes problems may occur due to incompatibility of gateway also. If this works or if you come up with a solution yourself pls let me know.
All The Best!!

Can I upgrade from 4gb of ram to 8 gb of ram on my late 2008 macbook pro?

I think I am in the right forum. I have the previous version of the macbook pro. Not the unibody.
I read this...
http://blogs.technet.com/keithcombs/archive/2008/07/05/testing-my-apple-macbook- pro-with-8gb-of-ram.aspx
Any thoughts?
thanks,
C

You are in the wrong forum; this one is devoted to the unibody models that were introduced in late 2008. Yours is not a late-2008 model unless it's the 17" model that was minimally refreshed in October 2008. Be that as it may, you want one of the "original" MBP forums that are listed at the top of this page:
http://discussions.apple.com/category.jspa?categoryID=250
The long-established unofficial (non-Apple) word on the actual RAM capacity of your machine is that it can use 6GB without problems, but will almost certainly be inoperable or unreliable with 8GB installed. As far as Apple is concerned, it only supports 4GB.

Upgrade from SNow Leopard to Tiger question.

I have Max OS X 10.6.8 with Intel Core Duo. I recently upgraded to Snow Leopard. Can I upgrade to Tiger even though I do not have Inter Core 2 Duo?

Take time and read many discussions about Lion first. New concepts like can make life interesting:
No physical install disks, but downloaded over internet when you need to reinstall
A hidden Recovery Partition that must be protected during customizations of disk partitions
PPC applcations no longer run
Scrolling is "backwards" to what SL has because it behaves more like iPads than computers
Lion-original machines cannot run any OS prior to Lion, so no "SL partition for running PPC applications"
I am not saying "do not upgrade", just "read first". Those who run Lion will help you with any Lion issues.
As to upgrading the hardware ... good luck with that. Look on "ifixit.com" or Google it, but I have built PCs (installed the CPUs myself) and it can be trickybusiness.

How much does upgrading my macbook aluminum unibody 2008 from 4gb of ram to 8gb of ram cost?

Hello i would like to know if anyone has any experience of upgrading from 4gb of ram to 8gb on the aluminum macbook and how much would it cost at apple stores?

Check out OWC and DataMem, but quite frankly it doesn't make a lot of difference if you look for a cheap price. If the product carries a lifetime manufacturer's guaranty and the vendor provides a liberal return policy shop with your pocketbook. Be sure you get memory that meets the specs required for your computer. There's no advantage to buying a brand name.
