15-F018ca upgrade/ram slots

I want to upgrade the ram. I've tried to replace the only user accessible ram module under the laptop by a same spec 8gb module (but from Crucial) and it refuse to boot. Tried with a few other DDR3 and DDR3L (4gb and 2gb) but the only one that work and boot the laptop is the original one (samsung 4gb-pc3-12800).
Two questions: In the user manual and on vendor website they all list as two user accessible ram slot. In the bios/boot/utility tool it mentionned that slot/2 is empty. So where is it ? (have to disassemble the laptop to access it?)
And what memory is known to be a good compatibility for this serie of laptop ? (if a second slot is available 4gb+4gb configuration will suffice but if not what 8gb module is compatible?)
This question was solved.

Hi,
The manula clearly says on page #1:
Two SODIMM non-customer-accessible/upgradable memory module slots (Core i3 processors)
DDR3L-1600-MHz dual channel support (DDR3L-1600 dual channel support)
One SODIMM non-customer-accessible/upgradable memory module slot (Pentium, Celeron processors)
DDR3L-1333-MHz dual channel support (DDR3L-1600 downgraded to DDR3L-1333)
DDR3L-1066-MHz dual channel support (DDR3L-1600 downgraded to DDR3L-1066)
Supports up to 4 GB max system memory (DDR3L-1600MHz module)
Supports the following system RAM configurations:
● 4096 MB (4096 MB×1 or 2048 MB×2)
● 2048 MB (2048 MB×1)
Your machine uses "2.16GHz Intel Celeron N2840 Processor with Turbo Boost Technology up to 2.58GHz" that means only one slot and already max 4Gb that whay it says non-customer-accessible/upgradable memory

Are all 4 RAM slots USER-UPGRADABLE in 27", 2.8MHz, i7 iMac?

I haven't dug into my iMac yet but am wondering if all 4 RAM slots are user-upgradable... before I fork out the money for more RAM.
Currently I have 8GB (4x2GB). I thought the 8GB would be enough for the graphic designing I do (was managing with my previous 1GB on my other iMac), but quickly found out that I need a lot more. The max is 16GB (4x4GB).
Anyone know if ALL four RAM slots are USER-UPGRADABLE?
Thanks!

Yes, look in your manual and it will show you how that all four slots are user upgradeable. If you want to upgrade to 16 GB you will need 4 x 4 GB chips. OWC's memory is highly regarded on this forum because they specialize in Macs and provide quality products and service. Memory there can be found at:

Upgrade Early 2008 from 10.5.8, to ? PLUS a broken RAM slot

I have a Early 2008 white MacBook, 2.4 GHz Core 2 Duo.
As I understand it, if I want to upgrade to 10.7, I need to first purchase a 10.6 DVD, correct?
Is a multi license DVD available? I have 2 machines running 10.5.8, the MacBook and an iMac.
Also, the MacBook has been dropped, and now only 1 of the 2 RAM slots works. (I think the Logic Board is damaged)
It looks like it could normally support 6GB (4+2), but since I can only use 1 slot, can I use a single 4GB, or just a 2? (It currently only has 1GB)
I realize I should probably just buy a newer machine, but honestly this one does all I need. The only reason I am even updating the OS is because Firefox will no longer work, and some other similar things that are software related.
Thanks!

With the Snow Leopard OS X 10.6 retail DVD, the license is usually for one computer at a time to be using the installed system. However as soon as each computer is upgraded to 10.6.8 and running adequately, any computers fated to access the App Store or Mac App Store for OS X upgrade to 10.7.5, would no longer be running Snow Leopard 10.6; so the license would be open for another upgrade at least to 10.6.8.
The ailing Mac with only one RAM slot should probably not be upgraded to a higher OS X than 10.6.8, in fact you'd likely need all the supported RAM an undamaged computer would normally have in a full upgrade, for a later OS X to work adequately. Given the damaged machine is running on borrowed time, and needs a hardware repair (such as a specialist authorized Apple repair service can do, in or out of warranty) the least effort involved would be better.
The older iLife and other applications that ran OK in Leopard 10.5.8 & earlier won't do so well after Snow Leopard 10.6.8 because a feature is not available after 10.6.8 by the name Rosetta to run older powerPC based applications that were common. Those will not run in later 10.7+ or without Rosetta installed from the Install disc in 10.6.8. This may add a layer of difficulty if you have application installers from another era.
There are a few fairly good highly capable portable Mac repairer service companies that could fix the issue in the partially failed MacBook for reasonable cost, and inspect the rest of the computer, before offering a warranty on their own work. Some of these also offer repaired models as part of their overall business. One that I have brief familiarity with some 8 or 9 years ago, was wegenermedia.com & sent an iBook to them in the mail. And recently discussed with them a repair to my first-edition MacBook 1.83GHz coreduo.
With only one RAM slot working you could try either chip, to see if one works better than another; however the way core 2 duo processors use RAM it is better if each slot has similar RAM, since it may affect processing as well as data flow. Later models really prefer matching spec sets.
Have you looked into the iFixit manuals to see the effort involved (if they show it) behind getting to the logic board? Some aspects of repair can lead to more damages than the cure was meant to fix.
Hopefully it will work OK.
Good luck & happy computing!

Trying to find if can upgrade RAM on early 2009 iMac 2.66. Has 4GB. Says has 2 slots each accepts 1067 MHz DDR3 module

I have an early 2009 24-inch iMac (2.66 intel core 2 duo) with 4GB memory and am trying to establish if I can upgrade the memory, hopefully to improve performance and prevent regular/occasional slowdown/sticking. Spec tells me I have 2 memory slots, each of which accepts a 1067MHz DDR3 memory module. It says all are currently in use and shows 2GB in each. So, question is can I upgrade or is this the max it can take? I'd like to upgrade, say, to 8GB, 4GB in each slot, if they have the capacity for that, which isn't clear.
Also wondering if this will improve performance - i.e. prevent occasional but sometimes regular sticking/slowing of performance, spinning wheel, etc. Activity monitor often shows just single or three-figure MB 'free' - mostly as a result of having multiple web pages open (have 8 saved tabs regularly open). That said, all my problems started some time ago when I 'upgraded' to Lion. But general view seems to be that memory is best bet for such problems.
If I can upgrade, am I right to understand that Mac memory is way overpriced and that it's OK/safe to use third-party memory and that a total non-expert can install that?
Any help appreciated.

Each slot can accommodate up to a 4GB module; upgrading both slots will max out your RAM at 8GB.
How much performance boost you see depends on many variables, one of which being your version of the Mac OS, which we don't know at this time. My experience is that, for the average user (word processing, web browsing, e-mail), 4GB RAM is fine up to Mac OSX 10.8 Mountain Lion. Please tell us what OS you have and how you use the computer (task-wise) and we can better suggest if an upgrade will help.
Install RAM in an iMac is an easy, 10-minute and at-home job. Video instructions here:
http://eshop.macsales.com/installvideos/imac_mid_2007_mem/
RAM is expensive if you get it from Apple. Fortunately for you, they only sell extra RAM for the latest models. For over a decade I have bought RAM from one vendor online and never had an issue. I find their Mac RAM roughly equal in price to RAM for the "Dark Side" computers. I am supporting about 25 Macs between family and friends, so have some credibility as an advanced user.
If you give us a rough idea of where you are located, we can suggest reliable vendors of Mac- compatible RAM.

Power Mac G5 Dual 1.8 PCI (4 RAM Slots) - want to upgrade to 8GB?

My computer is a Power Mac G5 Dual 1.8 PCI (4 RAM Slots)
Is there any way I can break out of the 4GB RAM limit into the world of 8GB RAM without having to buy a newer computer. I need to open a large 4.5GB TGA file in After Effects (48000 pixels x 36000 pixels).
Failing that, is there an application like RAM doubler I could use temporarily to get me though this job?
Power Mac G5 Dual 1.8 PCI (4 RAM Slots) Mac OS X (10.4.10) Currently have 4GB RAM installed

If there is not enough RAM, OSX will use space on the disk drive, so the amount of RAM should not limit the file size an application can handle, but speed will be reduced. 32-bit addressing can restrict the use of huge files, but there are ways that applications can get around it (at the expense of lower speed).
If After Effects has a file size limit, extra RAM will not help A later version (maybe using 64-bit mode) may handle larger files. 64-bit applications can be written to run in Tiger on G5s, but will be easier to write when Leopard is released.
You may be able to use some other application, such as Photo Shop, or Graphics Converter, to extract part of the TGA file, or reduce its size by changing its resolution, so you can use the result in After Effects.

B50-30 Memory upgrade/faulty slot?

Hi Lenovo I have an issue in trying to upgrade the B50-30 from the installed 4Gb to 16b except it seems as the 2nd slot is not reading the 2nd module placed in it. The site, and customer support for that site, I purchased the ram from state that the laptop will take 16Gb - according to Lenovo... but Lenovo show 8Gb max usable capacity in the Lenovo Solution Center app? Not sure if it refers to 8Gb max in the one slot - - - so a total of 16Gb? I therefore have a few questions to ask: 1/ What is the correct total RAM the B50-30 will take? 8 or 16? Having placed both 8Gb modules in the slots and booting up I get a 'blue' screen with Lenovo logo and the 'busy' circle going round and it continues until the battery is removed; 2/ Does this indicate that it does not take 16Gb or a fault with slot 2? Placing 1 8Gb module in slot one works - - - BUT the machine is still VERY slow! I have tried placing the original 4Gb module in to slot 2 leaving slot 1 empty but get a black screen at boot up. 3/ Does this indicate that the slot 2 is faulty or that slot 1 must be occupied? 4/ How can I check if the 2nd slot is okay and working? I have placed 2 x 4Gb modules from a Toshiba X500 P33 machine (supposed max ram 8Gb but now running 16Gb) and neither ram works either together (as 8Gb) or as 4Gb in slot 1. I have assumed that these are not compatible yet they are the 'same' 204-pin SODIMM DDR3 PC3-12800 1600MHz modules as those sent for the 2x 8Gb upgrade! I purchased the machine for my wife in January this year and it has ALWAYS been VERY slow. I had hoped to speed it up with the upgrade but I am disappointed it is still slow with 1x 8Gb and seemingly can't use slot two! It is so slow that my wife does not like to use it - wont use it - and I'm feeling it was a waste of money to buy it. If it is faulty then that would possibly explain why it is so slow but I need to get this sorted... please help! Oh! If I enter the serial number for the machine (on the Lenovo site support page) I get an error message and told to enter the 'correct' number??? Lenovo Solution Center program for the machine shows: Product: 80ES, Serial SDK0F82993WIN, BIOS: 9CCN27WW(V2.05)

Hi FrankJ,
Thanks for Posting!
The Lenovo B50-30 Supports 8GB Max (2x 4gb)
http://www.lenovo.com/shop/emea/content/pdf/Essential/BSeries/B50DSEN.pdf
To Check if the RAM slot 2 is working, Try all the RAM module that worked on slot 1 into slot 2.
Note: You can use slot 2 even if the slot 1 is blank and the otherway around (No hierarchy).
The Ram module from your other computer may not work, because the Lenovo B50-30 supports DDR3L type of RAM which is a low powered module.
Hope this helps
Cheers!

MacBook Pro mid 2012 15" - one RAM slot gone bad

Hi,
Has anyone ever had the issue with not working RAM slot? My MacBook Pro mid 2012 (non-retina) suddenly froze and after restart was beeping three times every few seconds. I found out that the beeping signals bad RAM. Bought new chips, and the problem still exists. My mac can now run on one slot with 4GB RAM.
I did check the placement of the chips in the slots, i also checked one slot at a time, and one of them has gone broken.
Any ideas on how to make it run again? or if it is possible to replace the slots?
Brgds

The Apple-accepted cure for a dead RAM slot is a new logic board. Unless you ahve AppleCare, that will be an expensive fix.
An Apple service option is the "depot repair." Instead of working on your computer in the Apple Store, they send it to a centralized refurbishment facility where they fix anything they find wrong (except for cosmetic damage and damage from abuse like dropping) for a flat fee of a little over US$300. That is between 30 and 40 percent of the parts and labor charges if Apple installs a new board in an Apple Store. Sometimes they will install an new battery at the depot without increasing the flat fee.
The downside is that it takes about a week; for that level of cost savings, I could do without my computer for a week.
So take it to Apple and ask about a depot repair.
A low-tech and low-cost option is to expand on what you are doing now--using one slot. Although the official RAM limit on your model is 8GB RAM (two 4GB models), your model can actually handle a total of 16GB (two 8GB modules. You can ignore the dead slot and put an 8GB module in the good slot. My 2012 MBP has 8GB RAM and is completely happy running Mavericks.
Be sure to ONLY get the RAM from an Mac-savvy vendor. For over a decade I've bought all our Mac RAM from one supplier. This is their page for an 8GB module for your MBP model:
http://eshop.macsales.com/item/OWC/1600DDR3S8GB/
I would also trust Crucial on this one. For a change they recognize that your model can use more RAM than stated in Apple's outdated specs:

How to fix a malfunctioning RAM slot?

I tried to upgrade my Mac Mini (late 2012) from 2 x 2GB to 2 x 8GB after ordering the correct Crucial RAM from Amazon, based on user reviews. After my first installtion attempt, I found that the Mac mini would only recognize only one of the 8 GB sticks. The Blank 1 slot was listed as empty when in the system information retrieved via apple menu. So I repeated the installation 3 times but after the third attempt the Mac mini would start and beep and the monitor screen was black. So I reinstalled the old RAM and the Mac mini would beep again after turning it on. Upon closer inspection, I noticed that the top RAM slot wasn't holding the RAM tightly and the left clip plastic piece was little more flexible than the bottom piece. So I removed the RAM and inserted it at 45 degree angle and pressed hard so that it popped in place. Yet the Mac Mini beeps upon start. Even if the top slot is damaged, it doesn't want to run on the bottom RAM slot which seems to work fine. I purchase the Mac Mini in Feb 2013 and just spent over $100 to upgrade the RAM. It's a shame I will have to shell out more to fix it. Any suggestions?

The Mac Mini started with the original RAM after I had sealed the hardline crack with some lactate. The release and hold mechanism for the top slot became stiffer after that. The Crucial RAMs didn't work but I am happy that the mini can start with the original RAMs. There were over 2000 5-star reviews for the Crucial RAM on amazon but the latest reviews are negative suggesting drop inequality or compatibility issues. I am going to return the Crucial RAM and be content with the 4 GB RAM for now.

Macbook pro does not boot after upgrading ram

I have a macbook pro late 2011 which runs with mavericks operating system . I have tried to upgrade my macbook to 8Gb. Macbook does not boot when the two ram slots are filled with 4GB ram but runs well when the slots are filled with 2GB ram. When i try them individually with one slot of 2GB ram and another slot with 4GB they run perfectly which shows status ok in the RAM info. What could be the problem .

Around here, most of us recommend only Crucial and OWC for RAM because it's guaranteed to work with Macs and it's what most of us have. If I were you, I would return the RAM and look at purchasing RAM from either Crucial or OWC. If you can't get their RAM to work then you'll know that there's some trouble with your actual slots.
Good luck,

Is it possible to upgrade RAM in MacbookAir 4,1?

Is it possible to upgrade RAM in MacbookAir 4,1 Late 2011, 2G to 4G?

MacBook Airs are designed with a purpose that differentiates them from the rest of the Macbook line. That is to place weight and size reduction at one of the highest of priorities. In doing so, compromises have to be made. Upgradeable memory takes up addional space, in that it requires acessability and a slot interface, bot of which would add both weight and dimensional size to accomodate it. By making the memory an integral part of the logicboard, the computer can be made thinner.
So, when you buy somthing of the MBA's form factor, you have to pay special attention to buying the computer with all the options available at time of purchase that you & the computer will ever need, where those components are not upgradeable for space and weight consideration.
The MacBook Air, despite the desire, is not just a shrunken MacBook Pro. Space and weight savings is of a higher priority than is upgradeability in the MBA.

Cost of upgrading ram memory?

Hello
Does anyone know how much the Apple store will charge for upgrading RAM memory from 16gb to 32 gb on a newer 27" iMac (mid 2013)?
Many thanks
Kaylee

Much more than you would pay if you were to upgrade it yourself. On new iMacs, Apple charges $200 to upgrade it from 8 GB to 16, and $600 to upgrade from 8 GB to 32.
If you already own your iMac, the answer depends on its present memory configuration. If all your DIMM slots are occupied, you need to purchase four 8 GB DIMMs for a total cost of about $400. If you already have two 8 GB DIMMS, you only need to obtain two more for about half that much. Determine what you have by going to the  (Apple menu) and selecting About This Mac then click More Info... then Memory.
Purchase memory from OWC / MacSales or Crucial. Memory upgrades for your iMac are considered user-performed maintenance and installation is simple.
