2GB or 4GB?

Do I really need the 4GB MacBook, or is 2GB enough? I don't plan on doing anything really special on my MacBook, but I don't know much about this sort of thing.

Depends on how much it costs more to have a 4GB. If you're saving up on dough, and you don't do too much video/photo editing, then 2GB is fine.

Installing memory (iMac mid-2011) - mixing 2gb and 4gb

Hey!
I'm soon getting my first iMac and it comes with the stock 4gb memory. As there will be two empty slots, I'd like to install 2x4gb Kingstons to get 12gb. My question is, does it matter in which slots I put the new ones or is there a certain way it has to be done? For example, should they be like this:
4gb    2gb
4gb    2gb
or
4gb    4gb
2gb    2gb
Thanks! I'd really appreciate any help.

4gb    2gb
4gb    2gb
or
4gb    4gb
2gb    2gb
Absolutely the second one. They should be matched horizontally. You could also reverse the order on the second one:
2 gb   2 gb
4 gb   4 gb

Nano Software Versions for 2GB and 4GB??

I have a 2GB and 4GB Nano. When I hooked up to the computer the 2GB told me software version 1.3.1 was available. However, when I hook up the 4GB it tells me that 1.1.3 is the current version. If you go into the "About" menu on each it shows the versions exactly as I have written. Are these versions the same?

The two iPod nanos are different generations, and have different firmware.

Macbook4,1 (2008) RAM 2Gb to 4Gb

I want to extend my Macbook4,1 RAM, 2Gb to 4Gb.
The problem is that it only accepts one 2GB module and should accept both.
What I can do? Do I need to install something?
Thanks.

Do both 2Gb modules work?
Ie, install one 1Gb And then one 2Gb... Then swap the 2Gb for the other 2Gb module. Is one not working at all or is it that they won't work together?
Could be that one is faulty. If they both work seperatrly but not together I'd suggest contacting the supplier. I assume you've just bought these?

Upgraded from 2gb to 4gb of RAM and now my Imac freezes up all the time.

I have a 2009 model Imac and I upgraded from 2gb to 4gb but now after about 20 minutes of the computer being on it will freeze up randomly. It could be 20 mins - 3 hours of use before it freezes up. I did my research and I'm didn't get any RAM my Imac couldn't handle...so I have NO idea what's wrong. Any help would be greatly appreciated!

As old as it is have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a

2GB to 4GB: Will there be improvement?

I have a 2GHz C2D Mac Mini with 2GB of RAM. It's been working fine but I've been using Aperture lately and it brings the machine to its knees. Barring getting a new Mac, if I went to 4GB, will there be a noticeable improvement?
I know about the issue of addressing 3GB, so I'm fine w/ the 'wasted' 1GB as long as I see a performance improvement. Just trying to figure out if this is worth the investment.

Oh, and IMHO, a nice big external desktop Firewire HDD, 7200RPM or higher, will trump any internal HDD you put in the Mini, no matter how big and fast. The power and speed of a desktop HDD will even cancel out the fact that the FW port is slower than the internal SATA. A friend of mine actually took the time to measure it, and found this to be true.
An internal SSD could be even faster, but they are simply not cost effective, plus you have to use an external for storage anyway, since a 500GB SSD will set you back at least a grand. If you have that kind of money to spend, you are better off with a Mac Pro, bro'!

2GB or 4GB RAM Macbook Air

I want to buy a new Macbook Air, I was planning to buy the 4GB model, but there is a great deal in a nearby store for a 2GB model and now I don't know what to do.
The 'great deal' is a Macbook Air 13" 2GB RAM but with a 256GB SSD and a 1,86GHz processor for €1249 and you get a JAMO I200 white iPod system (worth €155) for free, which is something I don't really need, but I can use it.
The model I was planning to buy was the standard 13", 4GB RAM, 128GB SSD, 1,7GHz for €1203 (I'm a student so I get the student price)
I will use the MBA for Safari, music on iTunes, Mail, text editing (microsoft office and iWork), ... This won't happen a lot, but I will sometimes use it to edit pictures with iPhoto or maybe Aperture. So I won't be doing heavy video editing or something like that. I'm a modal student who wants a new macbook for basic stuff.
So my question is, should I buy the 2GB version with a better processor and bigger SSD + the iPod speaker, or should I buy a 4GB RAM version but with less SSD and a 1,7GHz processor?
Thanks.

Caution: the MacBook Air with the 1.86 GHz processor has probably a previous generation (late-2010) Core2Duo CPU. 2 GB RAM is also a bare minimum. You'll get more lifetime out of your Air with 4 GB of RAM.
The mid-2011 MacBook Air has a Core i5 processer, which at 1.7 GHz is considerably faster than, e.g., an 2,13GHz Core2Duo CPU (i5 CPU supports 4 virtual cores, and has a faster memory bus than the previous generation Air). The new MacBook Air also has improved power management and efficiency (i.e. it runs less hot when displaying multimedia, or doing some more heavy computing).
If you need to save money, check out "Apple Certified Refurbished" on the Apple Store web site of your country. The refurbished Oct 2010 13"-model (2.13 GHz, 4 GB RAM, 256 GB SSD), e.g., is currently €1199 (incl. tax) in the German web store.

2Gb vs 4Gb

Is the RAID controller in an Xserve RAID chassis 2Gb max?
We're using 2Gb SFPs at the moment, but have just received a consignment of 4Gb types.
Would there be any advantage in fitting the faster SFPs in the drive arrays?

Hi VTmaint,
Since the xraid does not support 4 Gb it does not make sence to put such an sfp in.
The xraid's throughput is in practise much slower than the 2Gb FC port. There is not much to expect from such an upgrade anyway.
You can use the 4Gb's sfp on the host though. You can connect to multiple xraid luns and get a higher throughput (through a FC switch).

Donald

RAM Upgrade from 2GB to 4GB -- Lots of questions...

I have a MacPro with the two dual core processors. It has 2GB of RAM in the form of four 512GB 667MHz RAM chips.
I want to double my RAM to 4GB, and I wonder what's the best way to do that?
If I double the existing RAM, that would mean 4 more 512GB RAM chips, all running at 667MHz. That would use ALL my chip slots, so that's the most RAM I'd be able to have in that configuration.
So.. why not pull ALL the 512s and replace them with, say, 2 2GB chips? If I do that, could I not also upgrade to 800MHz chips? Is there any reason that 800 MHz chips would be incompatible with my MacPro?
I'm a bit skittish about hardware upgrades, so if anybody's got any suggestions for a resource that can guide me through the process, that would be helpful, too. I'm always afraid I'm gonna bust a pin somewhere and destroy the computer.
Thanks,
--PS

4gb of ram isn't really that much. you can add four 512 but you may want more ram at a later time. if you are sure you won't, then go for it. RAM is best adding in groups of 4, but has to be in sets of 2. I would add four 1gb of ram. There are diagrams you can search out to show how to most effectively and properly install it. That would give you 6 gb and that's a pretty decent number for most people. You could add two 2gb. It's not the most efficient method and would not sqeeze every bit of speed from the ram but it would leave two slots open for further upgrading if you so wished. If you aren't a Photoshop person or Final Cut Pro or other heavy user, and just use one application at a time, 4gb is probably adequate. RAM is inexpensive enough for most people with a macpro that going for four x 1gb and moving to 6 is my recommendation. If you do use two x2gb there is no need to remove the 512s other than to possibly move them. dunno about the 800MHz chips. I think you can use them but don't need them and won't make use of the added speed. I'd use all of the same type of RAM just to be cautious.

Performance Difference Between 2gb and 4gb on a MacBook Pro

Hi Guys,
About to make the big purchase. I am wondering what is the proformance difference between 2gb of ram and 4gb of ram on the new MacBook Pro?
Thanks

I upgraded my new late 208 mbp and have been having ram problems ever since. My computer keeps locking up usually during video play and makes screeching noises and has weird 1 inch thick horizontal lines that go across my screen when it happens. I have to do a hard shutdown. I called macsales.com where i got the OWC memory and they said there is an issue with the video drivers and the third party memory. I have already had a replacement computer from Apple and it is still happening on a different computer. i did a fresh install of the OS but still having it. So be aware....it's already happened on two computers for me!

Upgrading RAM from 2GB to 4GB on newer iMac - No Dice..?

Hello, I have an aluminum 2.4 Core Duo iMac (7,1), with 2GBs of RAM and want to upgrade it to 4GBs. Bought (2) 2GB sticks from Apple and they popped in fine. Then, I got a black screen when I restarted, would not boot. So I swapped out one of the new 2GB sticks with one of the older 1GB sticks, worked perfect, 3GBs registered. Then I shut down and tried it with the other new 2GB stick, and that also worked fine, registering 3GBs of RAM.
I reset the PRAM under both configurations and the iMac still will not recognize the 4GBs of RAM, as it will not boot up.
Any suggestions?
Thanks,
Dan

Dan,
Very strange as the iMac 7,1 can actually support up to 6GB of RAM.
0. See my signature below.
1. Just search this discussion area for 6GB.
2. See also http://eshop.macsales.com/item/Other%20World%20Computing/5300DDR2S6GP/
You wrote that you have a Core Duo, but the 7,1 is a Core 2 Duo (big difference).
I suspect that one or both of the new SODIMMs is/are bad.
1. Check to make sure that each 2GB stick is the correct speed. The label will either say: 5300DDR or 667MHz. Any other speed will not work.
2. You bought the memory from Apple, so march into your nearest Apple Store and get them to make it work.
3. Return the SODIMMs to Apple and get your money back and buy 6GB from OWC (see link above) for $40 less than you paid for 4GB from Apple.

Can i run 2GB and 4GB of ram in a 2010 mac mini?

as i know you can't run a 512MB with 2GB as the size difference is to great

A part of your physical memory is being reserved by your BIOS, depending on the installed hardware. What's left is for the OS to add to the virtual address space (physical memory + pagefile), usually no more than 3.25 GB for a 32 bit OS. Decrease your pagefile in size to a couple hundred MB, it might change something and you will barely need it anyway...
If it's available in your BIOS, enable Memory Remapping.

Downgrade RAM to 2GB from 4GB?

Long story short, I am upgrading my RAM to 8GB but don't have the chips (and won't until later next week.) The problem is that I have a buyer for my old 2GB 1067 chips at a good price and he needs them today.
So, I also have some 1 GB 1067 chips lying around and was going to downgrade for a week or two.
I obviously know that performance will be decreased if I downgrade to 2 X 1 GB from 2 X 4 GB, but would this, for any reason, cause firmware issues or any other issues including voiding applecare? I feel like this is an absurd question but I'm concerned.
Thanks in advance!

would this, for any reason, cause firmware issues or any other issues including voiding applecare?
No, unless you damage the computer in the process.

Is there a big advantage upgrading to 4GB from 2GB of memory?

I noticed that occasionally my new MacBook will hit the swap file when using such applications as Google Earth but never seen such behavior before on my old iBook. Would this be a result of the shared video memory with the Intel GMA X3100?
Back to my original point or question though, would I see a big performance gain going from 2GB to 4GB of memory?

Probably not. I just got 4GB because it was cheap and I liked the idea of maxing out the memory so I wouldn't have to worry about feelings of inadequacy.

PS Custom Format Plugin - Issue Reading Files 2GB & 4GB

Is this issue fixable within our format plugin code, or is it a photoshop limitation?
I am new to Photoshop & Photoshop Plugins. I have reviewed the sdk photoshop documentation & searched web on this subject.
I am working with a photoshop format plugin written by my predecessor who is no longer here.
The plugin is modeled after the simpleFormat plugin.
The plugin is being used on systems running Photoshop CS6 & CC on 64bit Windows 7 with 8GB or more memory.
The plugin allows a file of our format to be opened, read and written.
ISSUE:
The plugin works fine reading files < 2GB or > 4GB. For files between 2GB and 4GB, the call to allocate memory fails.
In the plugin's PIPL structure:   the FormatMaxSize {32767, 32767} and PluginMaxSize {PlugInMaxSize { 2147483647, 2147483647 }
In the plugin code; the DoReadStart() method opens the file and reads the file header information. This works fine.
Next, in the DoReadContinue() method: SPsBuffer->New(&bufferSize, buffersize) is returning NULL.     see below.
void PluginMain (const int16 selector,
                                                                         FormatRecordPtr formatParamBlock,
