Adding More Memory ~ Mixing Brands Ok?

My 2.66 Mac Pro came with the standard 1GB. I later added another 1GB from DataMem. Now, I'd like to add another 2 GB...would I be better going with Crucial or staying with DMS?
Thanks!

Another way you could look at it is:
- Your Mac Pro is peppy now and you want to increase some memory. By all means buy the 2GB now.
- When your Mac Pro feels no-so-peppy, increase your memory by filling up the rest (to make all 4 banks filled)
= Instant pep!
From http://diglloyd.com/diglloyd/free/MacPro/memory.html
The results show that using 4 modules instead of 2 offers at least a 70% increase in memory bandwidth. Dual-rank modules offer yet more performance than single-rank modules, with 4 dual rank modules offering twice the bandwidth of 2 single-rank modules.

IbookG3 wont recognize memory stick or burn disks after adding more memory

I recently added more memory to my old ibook. Now when I put my memory stick in either USB ports nothing comes up on the desktop. I also can't get anything to burn onto disc. Any ideas?

Hi, and welcome to Apple Discussions.
Have you tried removing the RAM to see if those capabilities return to the iBook?
How big is the hard drive and how much space remains available on it?

Is there anyway of adding more memory to an iPod touch?

Is there anyway of adding more memory to an iPod touch as I am running out of space.
Thank you

It's annoying because the amount of memory apple advertise is not actually all for you to use. I bought an 8g iPod thinking it would be enough but didn't realise 2g of the 8g is already used for you!

Adding more memory...

Hello everyone. I currently own a 15" MacBook Pro w/ a single 512MB RAM. I use a lot of Adobe products (I'm a Graphic Design major), and unforetunately they all run under Rosseta. Now, I don't know if it's hella slow because of Rosseta, or the memory that I currently have. Do you guys feels that it might run faster if I ad more memory, or those it not matter because it's running under Rosseta? Another question is: if I istall windows on my MacBook Pro, would it be better to just run the windows versions? Thanks to whoever can solve this for me.

hi -
adding memory helps everything, the finder, apps under rosetta, everything. depending on how much $$ you have available, a 2nd 512MB stick would really help.
even better, but more expensive (~$250) would be to remove the 512MB stick and put in two 1GB sticks... yeeeeeehhhhaaa!
re: the second question.... if you boot into Windows via Bootcamp, and install the latest versions of the adobe apps under that windows partition, they might indeed run faster. not all adobe products are universal binary now, so rosetta will be involved until they become UB...
maxxing out your memory will certainly help rosetta. but still there's an emulation layer there that isn't there if booting into WinXP via bootcamp.
if you interested in the maximum possible graphics performance under windows, you should go the bootcamp route, not Parallels.... Parallels is fine for a lot of things, but intensive graphics isn't one of them...
cheers

OS won't boot after adding more memory

Hello, I have one of the first Power Mac G5s (Single 1.8-Ghz, 8 DIMM sockets). The machine came with 512MB of RAM standard.
I'm trying to add more memory, but when I install additional modules, OS X doesn't boot up. I've tested the modules on their own, and they are fine.
When memory is installed in DIMM sockets 0 and 1, the computer is fine and boots up as normal. When I install the next pair, nothing happens. The computer turns on but nothing happens. Blank screen, hard drive isn't clicking, etc.
I've followed instructions from Apple, and I've attempted resetting PRAM, but nothing is working.
Should I reset PRAM before I install the modules?
Any advice would be appreciated. Many thanks in advance.

Sometimes even two batches of RAM from a "good" vendor like Crucial are incompatible, and you're saying each set works on their own but not when installed at the same time.
With the new set in, run AHT and Memtest to be sure. AHT should be able to load - but maybe not.
When swapping RAM, either boot into Open Firmware and reset-nvram or try the old keyboard "zap pram/nvram" routine.
It may be that the latest memory is trying to be "backward compatible" which doesn't always work. You're G5 1.8-SP is a very early Sept/Oct 2003 model.
You should always reset nvram when changing hardware configurations.

Adding more memory to Macbook Pro

Hi Guys
I own a 13 inch Macbook Pro 2.3 GHz Intel Core i5 which currently has 4GB of memory. It often seems to run quite slowly, so I was wondering whether it might be worth upgrading the memory on it. Based on what I've read online, it seems the way to tell if you could benefit from more memory is to look at page ins/outs. Compared to what I've seen online mine seem to be quite high.
I wondered if you guys could advise as to whether or not I could benefit from some additional memory? Would I actual notice any improvement in the performance of my MBP If I were to add more?
Thanks in advance!
George

General rule is if page outs exceed 10% to 15% of page ins, you can use more memory for the programs you run. In the picture you posted, essentially page outs = page ins. You can use more memory.
Your 2011 MBP can use up to 16GB of memory. Recommend installing in matched pairs, ie 2 x 4GB, for slightly better performance. OWC and Crucial are two good sources.

Thinking about adding more memory, Looking for suggestions

I have the late model (2008) 13 inch MacBook, alum body, currently have 2GB looking to upgrade to another 2GB or adding 4 to get up to 6GB. Is this possible with my MacBook? If so, can I buy it from Apple or are there other reputable retailers to purchase from? How easy is it to install myself?
Thanks

Hi El Kapitan,
Your MacBook supports a maximum of 6GB of RAM, although Apple only officially supports 4GB of RAM. So should you decide to upgrade to the 6GB option understand that if you require support from Apple (hardware or software) then you may run into some resistance.
Apple's RAM is more expensive then places like crucial.com or 4allmemory.com or macsales.com but you'll find a pretty 50/50 decision on what users prefer. I've gone the route of both (using all three of those above URLs) and I've always had a good experience. On the other hand, times where I've purchase the Apple RAM has always been just as positive with the additional peace of mind (dealing directly with Apple vs. 3rd party & Apple).
Installation is a little bit trickier (than say the white/black plastic MacBook) but nothing that I'd define as difficult. Here's the URL with an explanation - http://support.apple.com/kb/HT1651

Added more memory to iMac, now it starts up slower

I just upgraded my memory from 8gb to 16gb on my iMac (mid 2010). It now takes longer than usual to start up. other than that, it seems to run ok. Any thoughts? I kind of thought it should start up a bit faster than before, not slower!

15-30 seconds more could be deemed acceptable as RAM is checked by the system at startup. You've just doubled what you have installed so as long as startup time has not increased by minutes I would say that's normal.

L35 Adding more memory problems

I can not get the second gig of memory to work on my L35 S2366 - any thoughts

Satellite L35-S2366
Toshibas are finicky about memory. Very likely the memory you've added is incompatible. Unless you want to cut and try, use the better memories produced by Kingston. They are recommended and supported by Toshiba for add-on.
For the details, see Kingston's Memory Configuration for Toshiba Satellite L35-S2366
Installation instructions begin on p. 52 of the Satellite L30/L35 Series User's Guide.

my 2009 mac book has the pinwheel popping up alot any ideas?

You'd have to look into Activity Monitor utility, to see if any applications or processes are running or hogging system resources; not just RAM (as it may seem OK even if it isn't; esp in Mavericks) but in the areas of hard drive capacities. Could be you have some other issues not just a too-full hard disk drive, or not enough RAM installed.

Another utility that could show you plenty of busywork things going on, is Console. The system logs in there can show a detailed list of tons of activity. Perhaps some of the often-repeated results may be worth considering; and go by the time (day, hour, minute) you notice the spinning wheel; look into the logs from then.
Have you tried starting up in SafeBoot (shift key held on startup, then login screen appears, hold down shift key again when you login) and then run Disk Utility's repair disk permissions? When done, you could try & restart the computer normally.
If you happen to get incorrect specification RAM (close but not correct) that could also play into a spinning wheel deal; however the problem may be something else that RAM did not cure. Yet bad or incorrect RAM only adds to a pre-existing issue, since it could not solve it. Same with a System Upgrade. To upgrade to Mavericks with problems already does not mean they would go away; often that makes the first condition harder to resolve.
Good luck & happy computing!

Adding more memory (ram) to Aspire 5750

I moved the thread over to the appropriate forum. I also cleaned up the title so it's easier for others to find this content. I'm also including a screenshot of the RAM specs for the system. It can go up to 8gb using 2x 4GB DDR3 modules.

Do I need more memory on my iMac (Mid 2011)?

First and for most I want to make sure that I'm addressing the correct problem that's why I am asking a question that appears to be asked by many people on here. I mainly use my imac 27" to produce music (I use Logic and a LOT of plugins and instruments) and well I always get the following message:
I hate it because I get it everytime Logic reaches a point where a lot of instruments and sounds come in (It's annoying and ruins my work flow). I usually just have logic and chrome open, bc I close everything else to help my situation.
I bought my iMac thinking it would be faster than any laptop and I now realize that it doesn't matter if it's a laptop or a desktop but rather the memory it has and other things included. Anyways what would all of you recommend? What would be most useful to change? Would it just be adding memory (increasing the 4GB)? Thanks for your time!!
<Image Edited By Host>

I would just like to add to what everyone else said about 4GB really not being enough for doing much of anything. Even Safari and Mail can easily run up to the limit.
If you are running up against the memory limit, your computer will start doing what is known as "thrashing". On an OS like iOS, too much memory simply causes running apps to be killed. On Windows and OSX, if you try to use more memory than what is available, the computer will start to use a disk cache as if it was memory. It will try to put the "older" items in memory to the disk. If you need to access that memory, the OS needs to load it back from disk. The problem is that the disk is about 20x or more slower than memory. When your computer is thrashing, it will seem like it is not working at all.
If you are not running against the memory limit, then adding more memory will do absolutely nothing to improve performance. If you are running against the limit, you will be amazed at how much faster your computer will run with the extra memory.
As far as adding memory goes, as others have said, you need to add them in matched pairs. Also as other have said, the 2011 iMac secretly supports 8GB ram cards. (check OWC at macsales.com and they will confirm).
My advice would be to buy two 8GB cards ($109 at OWC) and add them in addition to your two 4GB cards. That will give you a total of 20GB. 20GB is TONS of memory and I am 100% sure that should be plenty for you. More is almost definitely overkill. You could almost definitely get away with adding 2 4GB cards for $50 as well (this would triple the memory you currently have), but memory is getting really cheap, and is a great way to "future proof" your computer.
If you want to see what your computer is doing, try looking at "Activity Monitor". If you start it up, sort the processes by "Real Mem" and you can see which processes are using the most memory (some of the processes will have cryptic names, but you should be able to tell most of them).
Also, click on "System Memory" at the bottom. Look at the "Page Ins" number ... if it is large, that means that you have been running into memory issues and having to "page in and out" memory to / from disk. You can also see what your processes are using currently. I forget exactly how OSX classifies the memory in each category, but Free is memory that is totally free, and "Wired" is memory that is in use. Active is basically memory in use, and Inactive is memory that is not really being used and can be made available for other processes, but I believe its being kept around in case the process that last used it decides it wants it back.
