I upgraded my late '09 13" MBP to 4gb, but one of the sticks apparently died. I'm about to replace it with my old 1gb stick so then I'll have 3gb total ram.
Will this turn off dual channel mode?
Computer has 2x512 memory sticks. Can I add one 2gb stick since the CPU sees only 3.3gb total? I realize I'm losing dual channel capabilities.
View 1 Replies View RelatedI know many say that the sheer volume of 16gb outweighs the speed difference between the two channel settings, but I'm wondering how 32-bit programs (mostly audio applications) will address the RAM best?

Looking for an upgrade to a 4 GB can I use a DDR3 Memory, currently have DDR2- 2GB.

MacBook Pro, Mac OS X (10.6.8), Has a 2GB of RAM - DDR2 SDRAM
What do you guys think?I am also curious as to the clock speed of the new upcoming processors. Online it says the fastest one they have is 3.2 GHZ, so will the speed increase come from DDR3 memory and no frontside bus?Does anyone know the actual technical differences between the current processors and the upcoming, other than the memory and frontside bus?
View 11 Replies View RelatedCall me crazy but are we all assuming the Nehalem Mac Pros can operate in triple channel mode based on the memory configurations suggested by Apple? I can't find anywhere on Apple's site or in the user manual that spells out the ability to run in triple channel mode. I know the integrated memory controller can operate in dual or triple channel mode. Being dual only would explain the number of memory slots. Can any owners of the new Mac Pros confirm triple channel operation? Or has anyone seen it documented one way or another by Apple? I'd love to be wrong...

I've only got 2gb and am running Lion, which slows everything down.I got a 2gb and 4 gb from OWC but the folks at the Genius Bar tell me that the MacBook ishould have no more than 4gb and that the memory slots need to be equal.

I am running a PowerMac Dual 2.0 G5 with the latest updated version of Tiger. I have maxed out the RAM to 8GB and upgraded the original video card to support my 30" display. I use a helper applications called "Free RAM". This program basically calculates what RAM you have available.
I am a graphic designer and need to run Quark Xpress 7, InDesign, Photoshop & Illustrator (CS4 with latest updates) simultaneously. On top of these 4 I also run Mail, Safari, Acrobat Professional, Extensis Suitcase X and iBiz (time management). These programs are all running all the time.
After launch and all apps running, everything is great. I have 2.95 GB of RAM still free (Free RAM). As the day goes by, and I have opened and closed numerous files this amount of free RAM dwindles and eventually I am left with 96 mb of RAM just before the CPU says "Enough is enough!" and everything grinds to a halt. Now previously I was running CS2 and I never ran into this issue. The problem started when I upgraded to CS3. Now with CS4 I am seeing the issue almost daily.
Now comes the question... Is the issue simply outdated hardware? Or, do I have a software issue.I am afraid to purchase a new CPU in the attempts to remedy this problem. If, in fact it is only a software issue. I find it strange that after a restart I have almost 3GB of RAM available. And yet as the day goes by I run out of RAM. I understand that as I open files more RAM will be used to support the open file.However, after the file is closed the RAM should free-up and be available again.
I used to buy Mac DDR3 ram from New Egg, I used to buy Crucial but they no longer sell it, so I want to stick with Crucial since it works the best, but wondering where everyone else is getting their ram and what brand.?

I am considering upgrading my RAM from 2GB to 4GB today at the Apple Store, and was wondering if I will notice a significant performance boost. 2GB is fine, but occasionally I'll get that annoying beach ball. It's $150 for a 4GB boost, and I have the 2.0GHZ aluminum MacBook. Would it be worth it for me to upgrade it?

I purchased a brand new Macbook Pro from Best Buy a few months back, it is the 13" unibody with a 2.26 ghz dual core processor and came with 2gb of memory installed. I just bought the two sticks of memory from [URL] which were Kingston DDR3 1066 204-pins, 4gb each. My friend told me that my Macbook Pro will only support up to 6gb, but my manual says that it supports up to 8gb. He also said that people have been having trouble with their motherboards by installing too much (8gb) of memory. I've done some research and looks like I'm good to go, but just want some reassurance before I install the new memory. One last thing, he also told me that 8gb is only supported on the i7 processors?
View 7 Replies View RelatedWhen I plug my MacBook into an external audio source via the headphone-jack using the red and white cables (do not know the technical name), I only receive sound out of one speaker. At first I thought one of my stereo speakers had blown out, but I plugged my computer into another stereo using another cord and it still only plays one speaker. Also, when I plug in any set of headphones I only still receive sound through one speaker (the left one). My computers speakers still work, and when nothing is plugged in it still says under the output type that it's Built-in Output. I also noticed that sometimes (but not every time) when I unplug something from the headphone jack that a red light flashes around two times, but it does not stay lit when there is nothing plugged in.
**Another note: The sound is not in mono in one speaker, it is just like one speaker is turned off.
Is there anything I can do with software to get my headphone jack to play in both ears. The jack plays in one ear. I cant figure how to play it in mono.

I recently purchased a Retina Macbook Pro 15" no more than 3 months ago.
Today I just noticed that whenever I connect my headphones I can hear the left channel clearly but the right channel is a lower volume and distorted.
at first I thought it was the headphones, but have tried various ones and it doesn't seem to be that.
Also, output from the internal speakers sounds fine, same level on both channels and clear

Or is it just waste money to install 16GB RAM in the MacBook Pro, cause in the menu it says MBP support up to 8GB of RAM.

The headphones work properly, the headphone jack doesn't. What should I do?
View 5 Replies View RelatedI have a white 13" MacBook. I'm totally Mac illiterate. I bought the Mac because I just about to dig my eyes out in frustration dealing with MS Vista. I like the MacBook.....but about a year and a half ago, the right channel of my 3.1 speaker setup cut out. It worked fine for the 1/1.5 years of ownership.
Internal speakers? Work just fine. Headphones? Perfect stereo.
External speakers with subwoofer? Right channel is dead.
I've tried max laptop volume and creeping volume on the actual speaker up. I've tried max external speaker volume and creeping the Mac volume up. I downloaded a ToneTester program. Internal speakers and headphones just fine. 3.1 externals? Right channel dead. I don't have the red-light jack issue. My Sound Output toggles between Headphones and Internal Speakers output perfectly. About 7 months ago while putzing with all the settings, I got it all back out-of-the-blue. Perfect stereo with subwoofer. I had it for about 2 months and then poof - right channel faded again.
I came across some youtube video with dual-language audio; ie. one language on the left channel and another language on the right channel. The Output page under Sound preference does not have the left/right balance control, probably due to the mono speaker in MBA. If I connect to an external speakers, or headphones, then the balance control re-appears. Is there a way to get around this problem, if I still want to use the build in mono-speaker?
View 2 Replies View RelatedI have a Dec 08 purchased 3.06 Intel Core 2 Duo iMac with 4G of 800 MHz DDR 2 SDRAM installed and lovely it is too
I note the new iMac's now use DDR3 RAM and wonder (for future reference only) if the DDR3 RAM would work in my iMac if I swapped sticks.
I suppose whilst I'm on a roll of asking a question....I may as well try another one.....
Would (again for future reference) the ATI Radeon HD 4850 512MB be fitable (if that was a word....which it is not) in place of my GS 8800 512.
I ha e 2x2gb of 1066 ddr3 ram sitting here. I am going to buy an iMac. I can't decide between the refurb 27 core2duo, the refurb 27 core i5 or the new 21.5" i3. Of course I am torn between cost and performance. I would prefer the bigger display but it's not necessary. If I could use my existing ram in the new 21.5 that may put it as the winner but I am unsure if I can mix 1066 and 1333 ram or not. If not then I will probably get the refurb 27 and then it's just to decide between i5 or core2duo
