Upgrading my MBP to 16 gigs of RAM - 1.35 volt vs. 1.5 volt?

Hey all,
There does not seem to be a diffinitive answer to this question. The picture below is of the existing ram in my Apple MacBook Pro 2.2GHz Intel Core i7 (15-inch DDR3) Early-2011. When I look this RAM up to find out the voltage, it appears to be 1.5v but I have not been able to verfiy that from a reliable source. Any ideas? Will it be labeled somewhere on the chip?
Crucial suggests a 1.35v chip
http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=0EA3E8DAA5CA7304
OWC suggests a 1.5v chip
http://eshop.macsales.com/item/Other%20World%20Computing/1333DDR3S16P/
A suggestion was made to me by apple (who could not confirm the voltage of the factory installed RAM) to match the voltage of the existing RAM.
Long story short...how can I verfiy the voltage of the chip below, and, does anyone have any other guidance on why I should use 1.35v (less power, extends the battery life?) or the 1.5v?

Yes any App that is RAM hungry will benefit from having more RAM, up to a point. Once you have enough installed that the normal apps you run do not use all of it then the extra is just left doing nothing. If those memory hungry apps aren't running all the memory is just sitting there doing nothing.
More RAM is much better then not enough RAM. But as I stated above "Adding more RAM will not make your system run any faster". It will just be able to run at its normal speed when you have a lot of Apps open at once or are using RAM hungry apps.

I do a decent amount of video editing on imovie, and only had 4mb of RAM installed. I was told imovie would run much faster with the extra RAM installed? not the case?

Does the 15" non-retina MBP accept 16 gigs of ram?

most of people who i asked told me that you can, but i read on one of the apple support articles that 8 is the maximum.

2011 Macbook Pro = 16GB DDR3 1333MHz 204 PIN SODIMM
2012 Macbook Pro = 16GB DDR3 1600MHz 204 PIN SODIMM
2010 Macbook PRO = 8GB DDR3 1066MHz 204 PIN SODIMM - unless it's a 13 Inch 2010 Macbook PRO - then you can upgrade to 16GB DDR3 1066MHz 204 PIN SODIMM.
use Apple Certified/Tested RAM to avoid complications/issues when you install them.

Upgrade to 8 gigs of ram mac froze

tried to upgrade mi ram memory to 8 gigs of ram n when i started my computer froze on apple screen no beeps or nothing just froze any help would be apreciated thanx

Adding to OG: get the Model Identifier from the apple menu (upper left corner of the menu bar), About This Mac, More Info, System Report - second line.
Then you can see exactly what memory that machine takes from http://www.everymac.com by going to the MBPs and find that model under the correct year.
You can also see the correct memory by going to http://www.macsales.com and find the year and model of the machine. OWC is an excellent supplier of Mac-compatible ram.

MBP A1150 2.16 installing 4 gig of ram

Hello everyone, has anyone installed 4 gig of ram on this older MBP? it is a A1150 2.16 duo core 15" machine. If you look on the original specs apple says no the machine only supports up to 2 gigs. I've read in allot of places if you use the correct ram that yes indeed you can put 4 gigs in that machine. Has anyone done it successfully around these parts? If you talk to the RAM dealers they say they do it all the time but i would rather hear from someone not trying to sell me something. My machine is getting slow, i push it hard with 10.6 installed, parallels running XP then have entourage and my financial software running. thats asking allot of this old machine but other then being a bit slow she is great. Thanks all in advance.

If it's a Core Duo model it only supports 2 GBs. If it's a Core 2 Duo model you can install 4 GBs but only 3 GBs will be usable. You can also install only 3 GBs (one 2 and one 1 GB modules.)

Upgraded to 1 gig of ram now programs load slow

Quoting from the Memtest86 readme
14) Known Problems
==================
Sometimes when booting from a floppy disk the following messages scroll up
on the screen:
X:8000
AX:0212
BX:8600
CX:0201
DX:0000
This the BIOS reporting floppy disk read errors. Either re-write or toss
the floppy disk.
Memtest86 has no support for multiple CPUs. Memtest86 should run
without problems, but it will only use one CPU.
Memtest86 can not diagnose many types of PC failures. For example a
faulty CPU that causes Windows to crash will most likely just cause
Memtest86 to crash in the same way.
There have been numerous reports of errors in only tests 5 and 8 on Athlon
systems. Often the memory works in a different system or the vendor insists
that it is good. In these cases the memory is not necessarily bad but is
not able to operate reliably at Athlon speeds. Sometimes more conservative
memory timings on the motherboard will correct these errors. In other
cases the only option is to replace the memory with better quality, higher
speed memory. Don't buy cheap memory and expect it to work with an Athlon!
Memtest86 supports all types of memory. If fact the test has absolutely
no knowledge of the memory type nor does it need to. This not a problem
or bug but is listed here due to the many questions I get about this issue.
Changes in the compiler and loader have caused problems with
Memtest86 resulting in both build failures and errors in execution. A
binary image (precomp.bin) of the test is included and may be used if
problems are encountered.

Im planning to upgrade my MBP late 2011's ram from 4gb to 8gb. Is there any specific brand of ram that i should buy or i can buy any brand that suits my MBP.

im planning to upgrade my MBP late 2011's ram from 4gb to 8gb. Is there any specific brand of ram that i should buy or i can buy any brand that suits my MBP? im aware of all the details that i need to consider pc3 - 10600 1333MHz 4gb. i just want to know is there any specific brand or i can use any brand,
Thank you.

The most reliable sources for Mac compatible RAM are OWC and Crucial. Macs seem to be selective with RAM so some brands will not work. Make certain that you get RAM with the exact specifications that apply to your MBP.
Ciao.
If you have a need, be advised that you MBP can actually support 16 GB RAM.

RAM upgrade for MBP 2.2 GHz Intel Core 2 Duo

I have a MBP 2.2 GHz Intel Core 2 Duo currently with 2 GB of RAM and with all the work I do on it I would like to upgrade to 4 GB. Purchasing the RAM through Apple is out of the question because it so expensive.
I would like to know what is the best brand to buy and on what website.. Is an upgrade to 4 GB possible for my MBP? It looks like I have my "Bank 0/DIMM0" filled with 1 GB DDR2 SDRAM 667 MHz and my "Bank 1/DIMM1" filled with the same thing. Does this mean that both of my RAM slots are full AND if I want to upgrade my RAM I'll have to purchase 2 sets of 2 GB RAM? Please help as I am new to all of the tech stuff...
Another side note... I've noticed that some discussions have stated that some MBP are only upgradable to 3 GB of RAM, but I'm pretty sure that I can upgrade mine to 4 GB of RAM. Can anyone shed any light on this?
Your help is much appreciated...

yes, both of your RAM slots are full, so to get 4GB you will have to get 2 2GB sticks. Having the same model I can safely assure you that it will recognize all 4GB of the new Ram.
as for brands, there have been many I have seen recommended on this board, but one name seems to pop up consistently is Kensington, I picked up my ram from the store I bought my laptop at, so I couldn't recommend a site, sorry

Putting 16 gigs of RAM in a non-Retina Display MBP

I see that the "new" non-Retina Display MacBook Pro shows a max of 8 gig of RAM. But I'm seeing kits for 16 gig, and even the Apple Store people seem equivocal about whether it will handle 16. Is there any harm in putting 16 gig in it? Any benefit? For that matter, is there a general answer to this question? What prevents me from putting as much RAM as I can find in? I'm told that there are firmware limitations, but again, I'm hearing different answers from different sources. Thanks!

Pardon my ignorance, but what are Apple PROMS?
Correctly stated I should have used "eprom". That is the firmware programming on the memory module that tells the computer what the memory is, how it is laid out and tells the memory how to behave. Memory without Apple eproms tends to either not work or to function erratically in a Mac - literally no guarantees. Hence the recommendation is to always get your memory from an retailer that has a history of testing their memory. Those retailers should all give 'lifetime warranty' and you want retailers that have been around a while. There have been tons of memory suppliers that lasted only a couple years.
The other side of the equation is that not all memory is created equal. Some memory modules are made by the chip manufacturers. Micron is the only US chip manufacturer and they make Micron Original and Crucial brand memory. Samsung, Hynix and several others are all high end chip companies that also make their own modules. If the chip manufacturer also made the module then they are referred to as 'original'. (the module being the PC Board containing the chips and afore mentioned eprom) Modules can be made by anyone. Anyone can buy any chips from any manufacturer and make up a module with them. These are typically called 'third party' or 'non-original' memory. WIth those the quality runs the full spectrum with much wider quality control than from original manufacturers.
There are good third party memory! Don't get me wrong. You just want to make sure the retailer that sells it to you has enough reputation to care whether they are selling good stuff or not.

Avoid overclock after ram upgrade on MBP late 2009

Hi guys, I'm from italy so please accept my poor english.
The problem is the following:
I installed a couple of 4gb ram 1066 (together with a 256 SSD) and all works fine but after the upgrade the computer heats very easly.
It reaches temperatures of 70-80° (celsius) if cpu usage goes over 50-60%.
I managed it with smc-fan-control, even if it is not namely correct.
Today I was editing a video in iMovie and I recognised that in activity monitor the cpu usage wass telling 170% with respect to iMoive process.
Is it possible???
iStat pro always tells me max 100%, but probably it's wrong because if really an overclock occured it explains my problems of temperatures after the upgrade.
Moreover, I never see a RAM usage more than a couple of Gb, so it seems that the ram is recognised, but not used properly!!
Running iBench the ram seemed to be used a lot, well above 6Gb.
Please help me

No overclocking going on. You have a dual core cpu which can have 200% cpu activity, 100% for each core. 100 + 100 % equals 200%.
Yes doing video editing put a stain on the system and it will heat up. Since your mac is a few years old it might have some dust build up in the fans or heatsink cooling fins. Use some compressed air to blow them out.

Yosemite performance on MBP 13" Late 2011 4GB RAM ?

Hello everyone,
I have a Mac Book Pro 13" Late 2011 with Mavericks and 4gb of RAM. I was wondering if anyone had the same system specs and had upgraded to Yosemite in order to know how it was running on their system ? Is it smooth ? The official requirements state 2gb of RAM but I'm really skeptical towards this.
Thanks for your input. Cheers !

I have the early 2011 MBP, 8 GB RAM, and I put a SSD in it (Samsung). I do some processor and memory intensive things, like audio recording and video editing, and I was not pleased with the performance in Mavericks until I put the SSD in.
I think it will depend on what you are doing with your Mac. 4 GB of RAM is probably enough to check your email with, but not if you are doing more creative work. Unless you like to see the pretty spinning beachball.
Regarding Adi's somewhat ranty note above, the usual cause for poorly performing Macs with OS X is crapware, like CleanMyMac, MacKeeper, or third-party anti-virus software, and having 57 startup processes active along with Parallels or VMWare, and expecting it all to run with 4 gigs of RAM.
Back to smashr: you can test drive Yosemite. If you make a Time Machine backup of your Mavericks installation, then you can easily go back to it if you don't like Yosemite. Alternatively, you can make a test partition on your HD and put Yosemite there.

After upgrade my MBP from snow leopard to mountain lion all my smb connections stop to work.
Now iám using mac os 10.8.2
I can see the server, I can choose the drive, but when try to open a folder the message on Finder is: You don't have permissions to see the content.
I already delete the key and try to connect again, but the problem persist. Already try change the ip from file server. Already try differents users. (admin, guest, etc...)
I have a windows server 2008 and a NAS working with SMB protocol. Both with the same problem.
That problem occurs only on Finder, if I try see the folder by Terminal, is possible to see my files.
Any Solution ?
Any Tip ?
Any Question ?

Not knowing how much RAM is installed in your iMac, your iMac can take a total of 8 GBs of RAM.
Before upgrading to Mountain Lion, I would strongly suggest installing the maximum 8 GBs of RAM.
Correct and reliable Mac RAM can be purchased from online Mac RAM sources Crucial memory or OWC (macsales.com).
Here is OWC's link to your model iMac and the RAM modules you will need.macsales
http://eshop.macsales.com/item/Other%20World%20Computing/8566DDR3S8GP/
You can purchase and download OS X 10.8 Mountain Lion from the Mac App Store in the OS X dock.
Before installing, it would be prudent to make a backup copy of all of your important data or your entire current system. Either using, optical discs, USB flash drives or external hard drives.
This is too insure protection of your data in case something goes wrong with the install of OS X Mountain Lion.
Good Luck!

Can I get a MBP with 32 GB of RAM?

Can I get a MBP with 32 GB of RAM?: I know someone is going to give me a 1-word reply: "NO".
But what I want to encourage is a bit of a discussion here. Why not 32 gb RAM? Isn't it about time? It can't be the price or?? Can't the software handle it?
I keep things a long time--- 10yr+ PBG4; 5 year MBP-13" --- and that's great when I could (and have) upgraded with more RAM, SSD's etc. But today's Macs are basically sealed boxes like an iPad I believe (talking MacBOOK / MBP's here, not iMacs)(although they are fairly tightly sealed nowadays, too!). So I really have to purchase thinking "What will I need in 2020 or 2022?" -or- "How do I win the lottery?"
Any comments appreciated -- I was planning to upgrade my mid-2010 MBP from 8 gb to 16 gb RAM (yes, you can… just this one model of that age) --- but perhaps save the $150 and put it towards a new one--- then again, $150 is only about 5 hours of an Watch so might just do that anyway…
Thanks,
Steve

I believe this IS a problem -- it is an issue I have about not being able to run things without enough RAM.
And I think "No you can't" is not a very helpful answer at all! In fact I prefaced my inquiry / problem with my first sentence thinking someone like you would give just such a reply---- was trying to avoid that!
There might be companies out there like OWC or Crucial or I don't know who -- that could / might / might some day provide increased RAM for existing MBP's just like for my MBP 2010 that is spec'd at 8 gb max RAM but there is a 16 gb solution out there.
So if anyone else would like to try to solve this problem for me --
Best regards,

Adding a gig of ram

A convert from the mini last march, I am recently new to the iBook. I am proud to own a 1.42 gighertz g4 60 gig HD CD/DVD burner 14 inch display 9550 chipset modern marvel.
So I gather that the 512 megs default is built in and I have a free dimm slot that I can put a gig in? Is that right? If so, even if it's easy, I am having it done at the store. Guess I coulda just called!
There is something else I am curious about and that is replacing the 4,200 rpm HD with one of those expensive, fancy, new, cool running 7,200 rpm laptop drives.
I am assuming that perhaps an actuall Apple store would not install such a thing. But can a non Apple owned Apple shop do such a thing, a licensed tech or some such thing where I do not have applecare and am taking responsabilty for something that might go wrong? I would not do this for a long time anyhow.
Enlightenment please.
And by the way, I am actually very happy with the performance of my iBook as is. If I can upgrade the ram, that's just inevitable. I sure am curious what a 7,200 rpm HD plus 1.5 gigs of ram would do for the already excellent performance though.
I am pretty fanatical about my iBook and plan on using it for a very long time before needing something new, except for maybe the next gen mini for my TV.
Thank you,
William
ibook g4 1.42 gigahertz Mac OS X (10.4.5)

Hi William,
Yes, you can put 1Gb in the empty slot. I suggest getting your RAM at Crucial.com. Crucial has a RAM guide, so you get the exact RAM that you need (at a pretty decent price). Apple has a RAM guide that will help you install the RAM into your iBook.
I suggest getting a external hard drive over getting an internal installed because you risk complications. No matter who opens your iBook, you risk having future problems. The other reason is that its great for backing up your internal hard drive. One should always backup their hard drive just incase anything happens to your computer. One can't predict the day when a friend trips over their own feet; knocking your iBook on the floor with a huge crash. The most annoying thing to carry around when traveling is the Mac OS X install discs. I hate bringing them with me because I am in constant fear that I will loose them. The reason I bring them with me is because if something happens while I am away, I can troubleshoot my problem. I can startup from the install disc and then run Disk Utility, Archive and Install, Erase, and partition my hard drive. Once someone has a problem on the road; they will never leave their house without the discs. Instead of carrying around those discs, I partitioned one of my external hard drives into three sections, one for backup (140Gb), one for Mac OS X Tiger (10Gb), and the last one is for Panther (10Gb. I gave my girlfriend an iBook and she has Panther on it). This means I am equipped to startup my computer without using my internal drive.
Have you ever lost your iTunes library or your TurboTax data? Well, by backing up your hard drive (internal to external), you can save all your vital data incase something happens. You will find it a life saver if anything ever happens.
If you are looking into external hard drives, I suggest anything from LaCie, SmartDisk, or Western Digital
I recommend the LaCie D2 Hard Drive Extreme w/ Triple Interface, SmartDisk CrossFire, or the WD Dual Option.
I use a SmartDisk CrossFire for both my iTunes library as well as my iPhoto library. If you need help moving your iTunes library you might want to look at Knowledge Base Document #301748 explains How to Move Your iTunes Library.
If you truly want an internal hard drive put into your iBook, you can get it done by an outside company like PowerBookResQ. It will cost you $350 instead of $160 for the external. With the external like the CrossFire, you get 160Gb, 2 FireWire Ports (so when your hard drive is plugged in you can still use FireWire), USB 2.0, and more at a lower price.
I hope that helps,
Jon
