Add ram to speed up Lion???

Hello, I have a MacBook Pro 15" 4 GB RAM, Intel Core 2 Duo, 250 HD. I Installed Lion the first day it came out and my MBP has been running slower and the proccessor is running 20 degrees hotter than before. I'm wondering if I should add more ram to speed thing up and get some more stability, or if my 2009 system is just to outdated for Lion.
When no Applications are running (except Active Manager) I have about 750 MB of free RAM.

Correct! It seems to be weird and I'm just a person that doesn't know what I'm saying but that's true! Lol! I didn't notice anything being slow at the time. I always keep all my Apps shut down when I'm not using them, so I never really have more than one app running at one time.
It seemed to be normal this morning as if I was running Snow Leopard again...but all I did was check out this discussion.
Right now with only Safari open I have about 2.25 GB.

Can you add ram to a Macbook5,2

Can I add ram to this macbook to be able to make it more compatible and be able to open applications that I can't without upgrading my software?
Is It worth it? How much Ram would I have to add for Lion software? Is that possible?
I am not in the position for a new computer and this one is good, it is just frustrating that some application that friends send to me do not open.
Thanks for you help and support.

The Model 5,2 (Early 2009, 2.0GHz Model Only) can use 6gb of 667mhz PC2-5300 RAM. The model 5,2 (Mid 2009, 2.13GHz Model Only) can use 6gb of 800mhz PC2-6400 RAM

Unable to add/remove users in Mountain Lion Server (Options are greyed out)

For some reason, im unable to add/remove users in Mountain Lion server. The + and - are greyed out. It seems like something is wrong with the permissons because it looks like it cant write the the Ldav3 file (although that may be speculation). Does anyone have any advice for me? I URGENTLY need to add users.
Maybe theres a way to restore default permssions for the boot drive (if that in fact is the issue). Hopefully there is a way that I can fix this while leaving all users, groups, their permissions and shares intact.

Anything interesting and relevent in the server logs?
Anything interesting in the server alerts?
Since it's far and away the most common cause of problems with OS X Server and with distributed authentication (Open Directory is entirely based on network encryption and digital certificates and on responses from your local DNS server(s)), verify your local DNS configuration is working and requires no changes with the following Terminal.app (Applications > Utilities) harmless, diagnostic command:
sudo changeip -checkhostname
sudo requires an administrative password. You might get a one-time warning about the sudo, and that can safely be ignored. The command will display some details, and indicate whether the local configuration appears valid and no changes are required, or further diagnostics for (most) common errors that can arise.

Will upgrading ram improve speed in Mac and windows (VMware fusion)?

I Am using VMware fusion for music production and that program requires a lot of workspace. I have a MacBook Pro 4gb ram and when I turn VMware on it goes to 2 gb ram in Mac and 2 gb ram in windows. My Mac speed is normal when VMware fusion is turned off but when I turn it on my Mac is very slow. Will upgrading ram improve speed in mac and also in windows (windows is also very slow)
Btw my english isn't very good

Adding RAM only makes it possible to run more programs concurrently. It doesn't speed up the computer nor make games run faster. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM hungry. It will improve the performance of applications that run mostly in RAM or when loading programs.
In your case it will most likely help. You should plan on at least 8 GBs or more, depending upon what your model supports.

Add RAM to MacBook Pro 13 Inch Late 2011

Is it okay if I added RAM to my MacBook? now my RAM is 6GB. this will make my macbook more heat or not because it need to process big RAM right?

Yes, it's perfectly OK to add RAM to your machine. It can use up to 16GB. There may be a minuscule increase in operating temperatures after going from 4GB to 6GB, but nothing significant.

Can i add RAM to new iMac 21 after purchase?

I'm about to buy a new iMac 21" and wanted to know if I can add RAM later if I want to.

Welcome to Apple Support Communities
You can, but it's very difficult and you will void warranty, so it's better not to do that and buy the iMac with the amount of memory you think you will need

I'm possibly wrong here but I suspect opening a brand new MBP to add parts yourself will void the warranty. It is probably in the small print. I certainly would not risk it for an expensive Apple product.
Some (Windows) laptops have easy access to memory and disk slots that do not necessitate taking the complete back cover off. However, Apple does not make life easy for you.
However, if you are going for a 'used' machine it is probably worth a try.
Not possibly, definitely wrong, Ram and Hard Drive are considered user replaceable and will not void the warranty if changed.

How do I add RAM ?

hello,
i am a tech freak and have a simple question here:
any one has any clue on how I can go about "adding RAM" and what that means ? i got a printer, Brothers HL 2040 recently and it prints fine from my ibook G4 OS 10.3, but I was also advised to "add RAM" "to it" ? What does that mean and how do i go about doing that.
xx

Hey Mr,
How on earth am I supposed to know, as a novice, ( and I DID QUALIFY THAT) that there is adding of RAM to a :
1. Printer
2. Computer ???
The question was unprecise for exactly that reason !! I didn't know, and needed consultation on whether in the context of having bought a particular model of printer, should one add RAM ?? I didn't know there is such a thing called adding RAM to a printer and adding RAM to a computer !
If that phrase is self explanatory from your perspective, then perhaps you needn't have answered my question. I don't think the sarcastic reply was helpful or is warranted.

ADD RAM To Imac

Hello,
I would like to add RAM to my Imac, could I buy it with Apple ?
Thks for helping

You can usually ask the local Apple Store about this; they'll ask you a few questions and determine if they can upgrade it for you, and how much it'll cost.
If you are thinking of performing this upgrade yourself, then you'll want to identify which iMac you have, as some models are easy to open up and access available RAM slots, and some are not. Recent 21.5" iMac systems don't have user-upgradable RAM, for instance.
Use  > About This Mac to see which model of Mac you have.

Parents' computer, oy--questions re: RAM, OS, speed, etc.

My parents won't use their computer for anything except email, because it's so slow. I want to fix a few things for them. Specs are at the bottom of the post.
Questions:
1) Can this computer take OS X 10.5? If so, do I have to buy 10.4 first, or can I buy 10.5 and upgrade directly from 10.3.9?
2) How much RAM can I add? And what kind of RAM do I need?
3) Where do I find instructions on how to install the RAM? (I'm not afraid of opening up the computer)
4) Should I buy the RAM directly from Apple, or can I go the Crucial route?
5) Can I install Open Office on this computer?
6) What else would you suggest to make the computer run faster? (At first I thought it was just web browsing, and possibly a modem or connection problem, but other software opens very very slowly, scrolling brings up the spinny beachball of doom, etc.). I have a sense that they've not used the computer wisely, and have probably caused some slowdown just by being computer illiterate.
ANY HELP AT ALL IS APPRECIATED.
Specs:
Machine Model: iMac
CPU Type: PowerPC G4 (3.3)
Number Of CPUs: 1
CPU Speed: 1 GHz
L2 Cache (per CPU): 256 KB
Memory: 256 MB
Bus Speed: 133 MHz
Boot ROM Version: 4.5.9f1

Hi,
1. It will run Leopard - Just. But not in its current configuration. Min' RAM is 512mb.
2. Max' RAM on this model is 1G ( I think ). Getting it to that level is no 5 minute job...
3. Here is how to take it all apart...
http://www.xlr8yourmac.com/systems/imacg4/imacg4takeapart.html
The correct tools, patience and a steady hand are essential!!!
4. Crucial dot com is much cheaper than Apple for RAM. There is also a nifty little "scan my system" feature on there.
5.Yes!
6. All of the above will take time and cost money. Only you can answer this next question... Is it worth spending all that time and money on a computer that is several years old?
If it were my money the answer would be - No. For the investment outlined above, you are almost halfway to a brand new iMac. It solves all the problems in a fraction of the time. Plus the G4 is still a very saleable computer - Perhaps even the other half of that new Mac?
Other considerations...
Leopard will take around 9Gigs of space on that drive. I would guess that you have a 40 or a 60Gig currently. Open Office will be another large amount of disk space. The speed issue you have currently may be due to lack of free space. Going through all the hoops as above is not going to make things any better.
Then there is the reliability issue - There are only 2 types of computer on earth. 2 and only 2! - Those that have failed and those that will fail. The computer is around 5-6 years old now. Hmmmm?
Hope that helps a little and good luck if you do decide to perform open heart surgery on the 'puter.
Regards.
Ian.

Can you add RAM to 2GB MacBook Air after purchase?

I'm thinking of getting a Macbook Air. Money is tight and 2GB RAM is cheaper than 4GB. If you purchase a 2GB MacBook Air, can you later add more RAM?

Depending on what you are planning to use the system for, adding more RAM may not be an issue. The current 11" entry-level MBA is a capable system which would only really begin to bog down if you were intent on running a number of applications at the same time. While 2Gb RAM is really the minimum for running Lion efficiently, the use of an SSD rather than traditional hard drive actually helps keep performance levels up, even when the system has to use virtual memory.
To my mind, for the average user, the 60Gb drive is more of a limiting factor.
