MB Pro - Attempting ram upgrade to 4gb

I'm trying to upgrade my 2.5ghz MBpro to 4gb - it only goes to 3gb. It's the correct 667mhz ram (2 x 2gb sticks) and no matter what configuration I try it doesn't work. I can get either of the 2gb sticks to work with the existing 1gb stick but they won't both work. Completely confused. Any ideas?

I just notice something in your post. If you are trying to upgrade a new aluminum MBP with 667mhz RAM, that could be your problem. You need 2x2GB PC3-8500 DDR3 1066mhz sodimm RAM memory modules. 667mhz RAM is for previous MBP models.

Retina MacBook Pro 15'' Ram Upgrade

Hello, my name is Joseph and I have 15'' Retina Macbook Pro.
Well, recently, I want to upgrade my ram from 8g to 16g, anyone knows how much it cost? how long it take?
if someone answerss these, it would be appreciated. Thank you! I hope you have a great night!

The Retina models can not have their RAM upgraded. It is permanently soldered to the main-board.

Macbook Pro 16gb ram upgradability

I'm looking into buying a Macbook pro and was planning on buying the non-retina display version. This laptop will primarily be used for school work, iTunes, video streaming, Photoshop, lightroom, aperture, and whatnot. Now i plan on buying the 2.6gh version, but Im wondering if the 8gb of ram it comes with is enough. I also heard somewhere that it would be recognized and wouldn't make a difference if i upgraded it to 16gb.
I would've liked to go with the new retina display model, but i can only afford the lower entrance model with the 2.3 processor, and i'm not sure if this would work for my needs.

My 2011 MBP can take 16 GB RAM. macsales.com sells the 16 GB kit for $160 currently. Apple tests against the more commonly available RAM types when publishing hardware limits, so only reports 8 GB as a maximum.
8 GB RAM is abut $50 through macsales.com, so buy the default 4 GB regardless of where you decide to go.

Win2k3 RAM upgradation from 4GB to 16GB

Hi,
Can we upgrade RAM from 4GB to 16GB in windows 2003 SP2 (32 bit) standard edition, by enabling PAE?
This is VM and hosted on 4.1 esxi.

See the link below but basically no. If your running 2003 SP2 Standard then its only 4GB limit. If your on Server 2003 Enterprise then you can go higher.

Early 2011 13" MacBook Pro maximum Ram upgrade amount

I have an early 2011 MacBook Pro 13" and am looking to upgrade my ram. I notice one Apple's website the maximum recommended amount to upgrade is only 8 Gb. Is it possible to upgrade to a higher amount without affecting my MacBook?

Not negatively. Apple didn't test it with the higher capacity modules before releasing it and didn't update its specifications afterwards.

Specific questions about a RAM upgrade to 4GB on my MBP

I have a MBP model MA895LL/A. Currently populated with the original memory (2GB)
Recent clean install of Snow Leopard, with all current updates.
Specific questions:
What memory does Apple use in their laptops? Does it really matter if you get the same manufacturer for complete compatibility?
Do timings matter? Will faster timing improve performance slightly, or is it a waste of money to go for the faster stuff on my specific model (Intel Core 2 Duo T7500)
Best to populate with 2 sticks X 2?
Finally, how about manufacturers? Anyone have any positive experiences with specific manufacturers, or, horror stories they can share?
I guess I just want to buy the best memory for my MBP. I build my own PCs, but I'm not sure if the Mac is a little more picky, RAM wise. Cost isn't really a factor. I'm willing to spend a little more, and buy the right stuff, and only do it once, without the hassle of sending it back, etc.
Any advice would be great. I know its possible this question has been answered many times before. I guess I don't know where to look...

Uh, yes, this is asked just about every day, like here:
http://discussions.apple.com/thread.jspa?threadID=2154109&tstart=0
Using the "Search Category" box in the upper right works.
To answer your questions, since you likely have the 2 slots filled with 1GB DIMMs, you need to get a pair of 2GB to max the RAM. I guess you could use 1 OEM stick and one 2GB stick for 3GB total, but I would just go for 4GB. If you are under warranty, save the original RAM, as Apple seems to dislike seeing any 3rd party RAM no matter what. Put the OEM RAM back in if you need warranty work.
I've seen several brands OEM, a lot of Hynix and Samsung, but it is probably all well tested to Apple spec. Otherwise, brands mean nothing, but see the above linked thread. I prefer to go with the exact spec'd RAM myself. I believe "faster" RAM does not run any faster. Vendors mentioned in the linked thread all have selector aids to find the exact RAM for your model.

Fan Noise After RAM Upgrade to 4GB

I have just upgraded the RAM on my Power Mac G5 to 4 GB and it is suddenly running very noisy with the fan perpetually running. This started the moment I restarted after installing the RAM.
The extra 2 GB of RAM which caused this was a Kingston 1 GB DIMM 184-pin DDR PC3200 DDR400 card. The specifications can be found here:
http://www.valueram.com/datasheets/KVR400X64C3A_1G.pdf
Can anyone suggest what the trouble is? Is it a problem with the manufacturing specs of the card?
Many thanks in advance.

One other thing, is if the air deflector is removed and replaced while powered on, the fans will run fast and not slow as they should. If this applies, see this document.
Also check that your System Preferences for Processor Performance are not set to "highest", as this will cause the fans to run fast.
And, one last thing (in my bag of tricks) to try is a SMU reset or PMU reset depending on your G5 model.

IMac turns itself off after an attempted RAM upgrade

I took the 1GB from the memory slot and installed
2x2GB which didn't work so replaced the original
1GB and now it shuts itself off after about ten
seconds of attempting to reboot. I've tried all
combinations but nothing works.

Doug,
I work as a sys admin at a college, we bought 90, 20" I Macs last November, we have had 3 break so far with the same problem, and one with a failed motherboard as a result of a bad power supply.
I have been a mac user for over 10 years and to have machines break after 2 months of use is shocking for a company that previously had such a good reputation for quality products.
This is a known issue, and the company that fixes our machines under applecare has admitted that these machines have a faulty power supply. I know the Rev A models had issues with power supplies, but the fact that all the 20" models have a 150 watt power supply doesn't help as this is not enough power to run a power pc plus 20" screen etc.
If i were you i would get it sorted straight away as other people have had this issue and it will only get worse if you dont get the power supply replaced.
Regards,
Kevin.

Problems with RAM upgrade iMac G5 1.8GHz

Stuck - Need Help!
I've previously upgraded up iMac to 2 500Mb RAMs and felt recently that it needed that little bit extra, so I ordered two 1Gb chips from crucial.
Followed instructions to T, but with the two new chips in, the machine won't load.
Interestingly, it boots up with the following RAM combinations
old 500MB + new 1GB (in any combination) - recognised as 1.5GB
one new 1GB RAM (again either one) - recognised as 1GB
I spoke to crucial who said that as the RAMs work individually, there isn't a problem with them, it could be a Firmware issue. I've upgraded all my software, and don't know what to do next?
Anyone overcome a similar problem in the past?
Thanks

I'm experiencing something very similar to shaow. I'll share my experience in gory details - sorry for the long post but I've spent more hours trying to stabilize. I should have worked the hours at walmart and bought a new iMac with the money I could have earned
Anyway, here goes:
Two iMac G5 1.8Ghz 17" (both Fall 2005 model), will call one A and the other B.
Prior to attempting ram upgrade: A, config working fine: both a config using 1GB slot 1, 256MB slot 2 and a single 1 PC3200 1GB stick. OS X 10.4-10.5.7. No problems. I did have the motherboard replaced under warranty after having sleep problems - capacitors were expanded. No problems since that motherboard swap.
Prior to attempting ram upgrade: B, config working fine: 2 x 256MB sticks. OS X 10.3.9
Ordered 3 PC3200 400Mhz 1GB sticks from Data Memory Systems.
Upgraded A: Added 1GB stick = 2GB total
Upgraded B: Removed both 256MB sticks from B and added two 1GB sticks = 2GB total
Booted B, experienced gray screen of death with the multi-language crash message - somethign like: 'Please hold down the power button and restart'. Power cycled B, booted off a retail box DVD of OS X 10.5.6. Began upgrade to 10.5.6. Gray screen of death part way thru upgrade. Power cycled, gray screen of death again during early boot phase.
Decided to run tests on B. I could not locate the Apple Hardware Test (neither on system dvd 1 nor on a separate DVD). I resorted to using TechnoTools Deluxe which was included with AppleCare box. No hardware problems found including on the 2GB memory.
Removed both new 1GB sticks, pulled older working 1GB stick from A and installed into B. Completed upgrade with just 1GB memory on B to 10.5.6 and subsequently pulled down all updates for OS X 10.5.8. Powered down, added second 1GB stick to B, booted into 10.5.8 successfully. Repaired disk permissions, restarted. Began using applications, then after only about 5 minutes experienced gray screen of death. Powered down, removed new 1GB stick, replaced with one of the two remaining new 1GB sticks. Read about reseting PRAM/NVRAM. Followed steps to reset PRAM then decided to do the reset NVRAM within openfirmware. Started back up and logged into 10.5.8. Ran several applications - did not experience gray screen of death after about 20 minutes use. Have not had time for further tests on B yet.
Back to my saga with A (my original iMac G5 that was working fine with 1GB stick on 10.5.7):
Called Data Memory Systems and they sent me a replacement for the 'bad' 1GB stick.
While I was waiting for the new 1GB stick from DMS, I was struggling to get machine fully updated. Software Updater was failing with the weird network error (network was fine) and after following steps to troubleshoot, I backed up the user accounts and decided to reinstall OS X fresh from the 10.5.6 retail box (family license). Finally, I had OS X 10.5.8 all fully updated on the 1GB iMac G5 (A).
New memory arrived, installed 2nd 1GB stick. Booted up, immediately I got the gray screen of death. Restarted, booted up got about 5-15 minutes use then gray screen of death. Puzzled, I called DMS who said unlikely I got 2 bad sticks. They suggested I try memtest. So I did...
So on A, I first ran memtest from single user mode on the 2GB config. It crashed immediately with some 'Unexpected' error. Did not look like a memory error. I powered down, removed 2nd 1GB stick, and ran memtest from single user on the 1GB stick. Ran all tests 3x over a couple hours - no problems found. Retested after swapping the 1GB stick for the other. Both tested fine. Installed both sticks again and ran memtest all tests, one pass (didn't want another 6 hours lost) on the 2GB config, and all tests passed. Booted up and got gray screen of death - I don't recall if it was on bootup or after running but I ran fsck with no disk problems found, then restarted, logged in, ran disk utility to repair all permissions. Some repairs were made. Restarted A, reset PRAM and NVRAM again, booted successfully.
I haven't had much time to run extensively apps on A yet. It's sleeping as I type this on another mac. My next test will be to reset SMU.
I'm starting to wonder if the original iMac G5 has firmware problems that would prevent it from being unstable with two 1GB sticks??? My experience on two identical models of iMac G5 plus reading this post with VERY similar behaviors and after all the normal tests. I've concluded the memory is A-OK and something more sinister is lurking...
Any thoughts are appreciated.

Sore thumbs from iMac RAM upgrade

iMac 27" i7 Ram upgrade from 4GB to 16GB, boy, these ram upgrade really gave my thumbs a hard workout! I've had at least a dozen Ram upgrades across PCs and laptops, never had to push the Rams in as hard as I did today. Still sore thumbs after 3 hours!

Try hard they pop up.
I just insert a 2x$GB in the free slots and it come with 2x2GB so like 12Gb.
Do you know the plastic tabs to remobe the modules?
I saw that one of them is like the paper in the photo,i see you have some experience upgrading ram so because none answer my post i decide asking you directly.
The 2011 imac is working for almost three months and it recognize the new memory modules but now i know that one of the tabs is touching a ram module,is that big problem?I mean no just because the static energy more because if the module become too hot(I even know if they become hot by use) the tab can burn,is something to worry about or just ignore it?
Thank you very much.

I have a MacBook Pro 7.1, it has 4GB of RAM, can I upgrade it to 8GB?

You have got a Mid 2010 13-inch MacBook Pro, and it supports up to 16 GB of RAM, so you can install 8 GB of RAM. You can buy more memory at OWC or Crucial

HT1270 I own a MacBook Pro 13 inch [dec 2009] 4gb ram. I'm upgrading it to 8gb. Can I increase the speed of the ram from 1066 to 1333 Mhz..?.

I own a MacBook Pro 13 inch [dec 2009] 4gb ram. I'm upgrading it to 8gb. Can I increase the speed of the ram from 1066 to 1333 Mhz..?
Which is the best company and is it necessary to buy it from the Apple store.

Let's clear the air here between fact and fiction.
Brand of RAM has little if anything to do with its quality.
A reliable vendor is more important that brand of RAM.
Installing faster rated RAM than required for your computer doesn't result in a faster computer. The RAM still runs at the speed of the system's memory bus.
Installing slower rated RAM than required for your computer will make the computer run slower.
Using faster rated RAM is a tricky business. Sometimes it will work and sometimes it will not work. This may be due to other factors related to your computer's memory bus speed and clock speed as well as other characteristics of the RAM such as CAS Latency (CL.)
The reliable thing to do is use RAM that meets the specifications set for your computer. That information is found in either the user manual or the system specs.

MacBook Pro 4,1 Ram Upgrade

I'm attempting to upgrade my ram from 2GB to 4GB on an early 2008, 2.5GHz, 6MB L2, MBP. I've purchased 2x2GB, PC-5300, DDR2-667MHz modules and attempted to install them. After installing the two modules my MBP would not boot. I contacted the manufacturer of the ram and they suggested attempting to install one 2 GB module and one of the original 1GB modules. This configuration functions properly. Both 2GB modules have been verified as functional when used with one of the original 1GB modules and have been tried in both slots. Any ideas as to why my MBP will not boot with more than 3GB of memory ?

Hi again,
Response from Centon suggests this: "MacBook Pro EFI Firmware Update 1.6 "
http://support.apple.com/downloads/MacBookPro_EFI_Firmware_Update_16.
I don't think it applies.
Model Name: MacBook Pro
Model Identifier: MacBookPro4,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.5 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 6 MB
Memory: 3 GB
Bus Speed: 800 MHz
Boot ROM Version: MBP41.00C1.B00
SMC Version: 1.28f1
Still at a loss as to why both modules won't work together. Centon advises that system should boot with only one module installed, I'll give it a try.
Many thanks

will i have any problem like compatibility??
thank you.

A Mid 2010 MacBook Pro supports 16 GB of memory without any problem. Macs are "special" about memory because some brands work without any problem and others don't work. That's why I recommend you to buy the memory from OWC or Crucial in order to make sure that you get compatible memory > http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3

Macbook Pro 13" (Late 2010, 7,1) 8GB RAM upgrade, boot up error

Dear all,
I am currently trying to update my brother's macbookpro7,1 13" to more current hardware with a new 128GB SSD and more RAM (he has 4GB). The SSD was installed successfully and runs perfectly fine, but when I installed the 8GB RAM into my brother's macbookpro7,1, it produces a black screen and a beep with 5 second pauses in between. I had looked up this error code and it indicates that the RAM cannot be found. This is where I am having difficulty understand, because I actually pulled the 8GB RAM from my other Macbook Pro 15" and it runs fine there. After noticing the error, I swapped back in the old RAM and both Macbook Pro's start up and run just fine. (Before I reinstalled the old RAMs to their respectively laptops though, I had attempted multiple solutions, like cleaning the RAM slots, reseating but to no avail, still black screen and beep.) The only difference I noticed on the RAMs are the 8GB are 1 Rank (1Rx8) and the 4GB is 2 Ranks (2Rx8) . Other than that, they are both DDR3 at 1066Mhz. Is the rank causing this problem? Please let me know, thanks!
Regards,
Jason

I'd suggest you look at the manufacturer info on the 8 gig modules, then check their website to see if it's compatible with the 13".
