Will Installing more RAM improve performance, IF laptop has "available memory" not being used?

My laptop has 2x 1GB of RAM.
Right now, and usually, The Physical Memory shown in Task Manager, shows that there is "available memory" (currently it's 500megs worth). (And "system cache" says 300megs.)
There is also, right now, 2.5GB of page filing being used.
If I were to replace the 2GB of RAM with 4GB (of the same Mhz), would there be a noticable increase in performance?
(windows XP 32bit OS)

A matched set of DDR2 ram will perform a lot faster one memory not matched. Its required for the double data rate to work. Hence 2+2 is the max you'd need/want in a 32bit machine. Windows 7 was built for large memory footprints. XP was built to run just barely in 64MB but really needed a min of 128MB to support a network connection and printing. It was never enable to truely go a whole lot further than a few machines built capable of 1GB. There was even a bug which was patch causing problems if a !GB or more was available. Just because it can see it does not mean it actually uses it !! The kernal by default is swapped in/out of ram even in larger memory systems. Why, it was is not aware of the extra memory and does not change its behavour from a 512MB machine.
As for the 1333Mhz ram the timing may be faster than the other memory used. Hence it flow the data faster on the bus. Fewer delays in various cycles including the RAS/CAS etc but thats all under the hood so to speak.

Will installing more RAM help my iMac run faster?

My Mac is circa 2006 and it is performing very slow. Let's say I see the beach ball way more that I should.
I have 2 GB's of RAM installed. Of the 2 GB's of RAM, its looks like I have used 1.75 GB's. I have 92 GB's of hard drive space available out of 320. So, my question is, if I install say, 4 GB's of RAM, will my system run faster?

An Early 2006 Core Duo only supports 2GB of Ram. If you have a Late 2006 Core 2 Duo 20 or 24" it will take 4GB, but only recognize and use 3GB.

Installing more RAM into my Macbok Pro

Hey guys,
I'm looking to install more RAM (from 2 Gb to 4 Gb) into my MacBook Pro (15.4" Intel Core 2 Duo 2.2 Ghz) that I bought last September, and I'm strictly a software guy: I know little to nothing about hardware.
What kind of RAM do I need to install?
Also, I have the AppleCare protection plan. Will installing more RAM interfere with that at all? Do I need to have a Genius install it for me?
I've installed a RAM, hard drives, and video cards before so I know I can do it myself if I'm allowed to by the plan.
Thanks,
- Keith

Open your computer's User Guide. There's a whole chapter on upgrading memory in which the specifications are explained. If you don't have the manual you can download a PDF version from http://www.apple.com/support/manuals/.
Installing RAM will not void the warranty unless you cause damage in the process.

Will adding more RAM to my Power Mac G5 make a difference?

I have a Power Mac G5 (Late 2005) with 1 GB of RAM, which is how I ordered it. Sometimes when I am viewing large (large viewing size) video files with Quicktime, the video files get a little choppy from time to time, especially when I have many other applications open. Will adding more RAM fix this or is it not really necessary? Also, does Leopard improve this problem? I am currently using Tiger.

Hey Tim
I'm definitely not an expert - but more Ram makes a huge difference. I'm not sure if more Ram will specifically solve your Quicktime issues or whether upgrading your graphic card is really the answer. Those more knowledgeable should jump in here. Buying Ram from 3rd parties, like OWC (making sure you do have the right compatible Ram), will improve your performance immediately. I noticed the difference when maximizing the RAm on my G4. It cannot hurt. 4GB of Ram for my G5 cost less than $200. I think Ram is the biggest bang for the buck.
Do you really need to get Leopard? The performance of Tiger on the G5 for me is solid. Seems like Tiger is optimized at this point for the G5 processor chips. Why muck around with all the potential problems you read about on these forums. Check out the Adobe forum and hear some of their nightmare stories. Who has this amount of time to waste on fixing what shouldn't need fixing in the first place. Just a thought - hope I'm not out of line for chiming in on this.
Since your model can take 8GB of Ram, indulge yourself and maybe buy another 4GB of matched Ram and if it doesn't solve your Quicktime issues, I'll bet it will make you happy with everything else.

Debating whether or not to install more RAM????

Hi I have a macbook late 2010. I currently have 2.4 GHz and 2 gb of ram. I'm debating whether or not I should buy and install more RAM. I was thinking I would either buy 2x4 or 2x8. Would this be a worth it upgrade. My only other option would be waiting another year, and buying a macbook pro then. Also is it even possibile to upgrade RAM on macbook? Any help would be appreciated, and please back up your answers.

You're welcome. Based on your usage, your OSX, and the relative prices, I would go with 8 (2 x 4 GB) modules. This won't make your machine faster in a traditional sense...rather, it will prevent it from being slow...as it is now with extensive page outs. I would recommend purchasing the RAM from Crucial or OWC (both companies test RAM extensively, are very reuptable, and provide 1 year warranty included).
There is no late-2010 MBP 2.4 GHz model. Confirm RAM compatibility at crucial using their scanner tool:
Scan your system to view your specific system configuration.

What do I gain by installing more ram ?

Hi !
I would like to know what are the advantages of installing more ram on my powerbook ? Would installing an additionnal 512 mb ram or 1gb ram speed up the idvd compression to dvd ? More generally while I gain performance on game graphics or video compression ( which takes quite a long time on a powerbook )?
thank you

Hi Yanis,
No performance gain in graphics speed, no, but
a smoother and quicker computer use in everything that uses "hard disk accessing" while running a task.
Simplistic answer:
The more RAM is available, the less tasks need to use Virtual Memory.
And RAM is much faster than VM, too.
If you often hear that your work uses hard disk accessing, then you'll be happy with extra RAM.

Instructions how to install more RAM Intel iMac 17"

Does anyone know where i can find instructions on how to install more RAM? Preferably with illustrations.
Thanks,

It´s supposed to be a phillips 2 screwdriver. It may also be difficult to open the lid if the screwdriver is too sharp. In Sweden we don´t usually call it by that name. If I only had read my swedish owner´s manual I would have knewn, or if I just had looked at the bottom of the computer before I purchased a phillips 0 screwdriver. That screwdriver might be useful in other situations and was quite cheap though.

I had major issues with the iPhone 4s battery, however it’s resolved.
The tech who set the phone up at the Apple store did so with little training.
if you have a mobile me account. First go and move all your data to the cloud by going on your computer and logging in at me.com/move. The cloud has replaced mobile me, so there is no need for those two accounts
Also make sure that for any of your email accounts you set them up to fetch, not push. My tech person set them all to have the email servers push data to the phone. The new iphone4s antenna is extremely strong so it will continually try to access stuff that is pushed–***** a lot of battery life doing this. It makes it worse if you have exchange 2010 accounts. Something about changes made to exchange really suck battery life from devices that access such accounts.
turning of locator and the push notifications from facebook--they have a lot!

Can't install more RAM, what will help?

OK need a bit of help.
My elderly iMac has been a bit problematic lately, spinning beach balls, laggy, that chuggy noise which I always think is Spotlight indexing... (can't think of a more technical way to describe it!). I've just nosed around and saw a thread saying take a look in Activity Monitor at System Momory. This is what mine shows.
The thread I looked at kept saying 'are there a lot of pageouts, without actually defining what 'A lot' of page outs were! Nosed a bit more and think I may have too many page outs?
Now, thing is, I'm maxed out on RAM, in fact this machine should only take 4GB but I managed to get it to accept 6MB, after doing some research and finding it was possible. So, I can't install any more RAM. Am also on Mountain Lion.
I have to trundle on with this Mac for a while longer. What can I do to improve my page outs and general speed of machine? Is it purely not having lots of applications open at once? I'm a designer so have CS6 installed, and use InDesign, Illust. and Photoshop. Is there anything I can do to get a bit more life out of this trusty warrior? Everything else on it works just fine.
I'm not 100% techie, but can usually sort out my mac problems if someone explains clearly!

There is excessive swapping of data between physical memory and virtual memory. That can happen for two reasons:
You have a long-running process with a memory leak (i.e., a bug), or
You don't have enough memory installed for your usage pattern.
Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
When you notice the swap activity, open the Activity Monitor application and select All Processes from the menu in the toolbar, if not already selected. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
The process named "Safari Web Content" renders web pages for Safari and other applications. It uses a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider it a prime suspect.
Another process often implicated in memory leaks is "inkjet8," which is a component of the HP printing softwre. If it's present, force-quit the process in Activity Monitor to solve the problem temporarily. If you don't use an HP printer, remove the software. Otherwise, if the problem is recurrent, update the software (which may not help) or contact HP support.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details.

Will adding more ram to my Macbook Pro make it faster?

So I have about mid-2010 Macbook Pro and after all these OS upgrades throughout the years (currently running OSX 10.9.5), it's starting to run annoying slow but still useable. My specs on this Macbook is a 2.4 GHz Intel Core 2 Duo processor and 4 GB of ram. If I upgrade my ram to 6 or 8 GB will my Macbook run a lot more faster? I use my Macbook mostly for entertainment purposes such as web browsing, movies and music as well as for school mainly Microsoft Powerpoint and Word. Also, if I were to upgrade my ram is it as simple as popping out the old ram and installing the new ones? Thanks.

Hi kidrobot123,
Thanks for your question. Think of Random Access Memory (RAM) as the amount of information your computer can think about at any one time. Your operating system requires a certain amount of memory for basic functions. Every software program that you have open needs memory as well. So, increasing the available memory is one of the things you can do to improve performance.
The resource below explains how to do it. I've highlighted the section of the article that pertains to your Mid 2010 model. Click on the link for more details.

Additional notes
For best performance, fill both memory slots, installing an equal memory module in each slot.
Removing or installing memory
Warning: The internal components of your MacBook Pro can be warm. If you have been using your MacBook Pro, wait ten minutes after shutting down the computer to let the internal components cool before continuing.
Step 1: Remove the bottom case
Shut down your MacBook Pro. Disconnect the power adapter, Ethernet cable, USB cables, security lock, and any other cables connected to the MacBook Pro to prevent damaging the computer.
Turn over your MacBook Pro and remove the ten (10) screws that secure the bottom case. Because the screws are different lengths, note the screw lengths and locations so you can replace the screws correctly. Put them aside in a safe place. Lift off the case and place it to the side.
Touch a metal surface inside the computer to discharge any static electricity from your body.
Step 2: Remove existing memory (if present)
Push the levers on the sides of the memory module in an outward direction to release the module from the memory card slot. The memory pops up at an angle. Before removing it, make sure you find the half-circle notches. If you don’t, try pressing the levers outward again.
Hold the memory module by its notches and remove it from the slot.
Remove the other memory module.
Important: Hold the memory modules by their edges, and do not touch the gold connectors.
Step 3: Install memory
Align the notch on the gold edge of the module with the notch in the lower memory slot.
Tilt the card and push the memory into the slot.
Use two fingers with firm, even pressure to push down on the memory module. There should be a click when you insert the memory correctly.
Repeat this procedure to install an additional memory module in the top slot. Press down on the module to make sure it is level.
Note: Make sure you install the memory according to this illustration, with the gold contacts inserted almost completely into the connector.
Step 4: Replace the bottom case
Replace and tighten the ten screws you removed earlier, making sure to put the different length screws in their proper locations.

Does installing more RAM void the warranty?

I have a new MacBook that I bought in late January. After having to format my entire hard drive and reinstall Mac OS X because of playing Civilization IV: Colonization, I am interested in adding more RAM/VRAM to my MacBook. I noticed Apple put up a tutorial on how to install more; does this mean that doing so does not void the warranty I have on my MacBook? Also, is installing it easy?

Also for future people it's very easy to change the RAM, open up the inside of the macbook pro, pop out the old RAM and click in the new, put the cover back on and turn on the macbook! it will take a longer time to boot up the first time, but then it will be much faster.
