4GB+4GB or 8GB+2GB Ram?

Hi,
I'd like to add more RAM to my mid-2012 Macbook Pro (without Retina) and I'm just thinking about these two options.
a) leaving one of my current 2GBs and adding 8GB (it will give me a chance to upgrade it to 16 in the future if needed)
b) changing both 2GBs to 2x 4GB
which solution is better? why? I heard that it's better to have 2 slots with rams from the same producer but I just want to make sure with it. Thank you!

You do not need two of the exact same ram. 2GB and 8GB would be perfectly fine.
2 x 4 GB would be a good choice too but you would only have 8GB RAM. 10GB Ram sounds a lot better.
Or you could spend a lot more and go with 2 x 8 GB totaling you 16GB ram but that would be too expensive and you might not get a big use out of it.
Bottom line, go with 10GB RAM and look at activity monitor to see how much memory you're using, then upgrade to 16GB if your computer requires it.

2GB, 4GB or 8GB of RAM enough for CC professional use?

Hello,
I have an urgent question I hope you can help me with:
I want to buy a iMac for my friend who is a professional media designer. She will be using InDesing, Illustrator (and Photoshop) mostly. I checked System Requirements and I found this:
2GB of RAM (8GB recommended)
What does that mean for using the Program, i.e.:
Will 2GB be enough to run it at a reasonble speed, or will working with, for example Illustrator, be slow and frustrating?
Do i need to get a 8GB RAM version (of iMac) to run the programs fast and without frustrating delays and problems, or might 4GB of RAM (for which I found the best iMac offers) will be totally enough?
Thanks for your help and experience in advance!!!
PS.: I am not a professional at all, so excuse any mix-ups of tech specs ; )

Given that InDesing, Illustrator (and Photoshop) are now 64-bit apps I wouldn't put in anything less that 16GB. RAM is cheep and the performance increase will be well worth it.

I have an 21.5 Mid 2011 iMac and i want to upgrade my RAM. Currently I have two 2GB and two free slots. Do I have to put in two 2GB in the free slots or can I use two 4GB or 8GB?

You can leave the existing RAM in their current slots and add compatible modules in the empty slots. For best performance, add two of teh same size. Our 2010 iMac 21" shipped with 4GB RAM---two 2GB modules in two of the four slots. I added two 2GB modules to the empty slots and now have 8 GB RAM.
Be sure to order RAM from a trusted Mac-savvy RAM vendor. Some vendors thing a Mac is a hamburger. For over a decade I've bought all our Mac RAM (and we have 18 Macs in teh family!) from one vendor:

The link is to the proper RAM for your Mac.
Crucial.com is also a trusted vendor.

IMac and Video: 4GB vs 8GB RAM

Hi all, long-time Mac user, first-time poster here. It's time to upgrade the old 2003 G4 MDD with a new platform. A Mac Pro is really expensive right now, so am looking at a 2.93GHz Intel Core 2 Duo, with 4GB of RAM and the ATI Radeon HD 4850 card. I intend to occasionally make videos -- let's say YouTube quality with the occasional family-release DVD. Is 4GB of RAM and say, Final Cut Express/iMovie, good enough, based on your experiences? I've more interest in Illustrator and PS and assume those are fine with 4GB.
It's $1k to double the RAM to 8GB -- that's a big chunk of Adobe CS's price. And do you think that Snow Leopard will treat 8GB better than 4GB for video?
I'm asking because I recognize that the iMac is not as upgradeable as the Mac Pro is. Thanks in advance for any thoughts -- a grand (or more) is riding on this!

You should be fine with 4GB; even 2GB may be sufficient for what you describe although that is irrelevant, since you cannot get that config with only 2GB of RAM.
If you really find a need for 8GB of RAM, you can upgrade it later using third-party RAM. The prices should come down. Even today, you can get a matched pair of 4GB modules from OWC for about $700
http://eshop.macsales.com/item/Other%20World%20Computing/8566DDR3S8GP/
and you get to keep the stock 2x2GB modules as backup. When you sell your iMac, you can put the original RAM back and have the 2x4GB modules to sell separately. That makes much more sense than spending $1000 up front, and not having the extra set of RAM.

Mac mini (mid 2010) RAM upgrade 4GB or 8GB

I have a mid 2010 Mac mini with 2GB of RAM. My question is - Should I upgrade the RAM to 4GB or 8GB?
Thank you, DZetko

It's is better to go for the full 8GB upgrade now,
that way you will not have to upgrade again when OS X and your personal usage demand more.

4gb to 8gb ram: Big help for LR?

I am running LR 4.1 RC2 on my Win7 64-bit 17.3" laptop. Here are the basic specs:
i3-330M 2.26ghz, 4gb, 500gb hd, 17.3" 1600x900 screen, Intel graphics (with latest driver)
Fortunately, I have not had the terrible performance problems that some people report, but it is still somewhat sluggish. Occasionally, even when I am not doing anything the ram usage will go from 450-550mb up to about 2gb for no apparent reason. Also, the cpu usage will go up. It only does this from time to time, but something is going on in the background. Maybe some of the times it is building previews in the background, but that is just a guess. Also, I discovered that any use of luminance NR really slows things down,. Now I wait until the last step before exporting an image to do that so that it doesn't interfere while working on that image in the develop module.
My laptop works well and except for LR is fast enough. I am wondering if going to 8gb would be the biggest bang for the buck change I could make for LR? Often that is the case, but looking at the task manager I usually have quite a bit of memory available, although when LR is really busy like exporting an image to a resized jpeg file the memory of the PC can be up to 95% usage. That drops down though when LR is done. The raw files I am working with are from 16mp and 18mp cameras and I don't do batch processing, just one photo at a time.
This laptop is 2 years old, but still running fine so I would only get a newer one with a faster cpu and more ram if I really thought it would help quite a bit -- or this one develops problems. Changing from 4gb to 8gb though is relatively inexpensive. What are your thoughts? Thank you.

I agree with your statement that 20 GB is probably ample for caching up to 40,000 raw files in LR4 and LR3.6 (see why below). Even using large 21Mp raw files that will hold up to 33,333 images before over-flow (20,000/0.6).
I know this is going off topic, but I'm sure it's of interest. I also thought that LR4.1 PV2012 stores different ACR cache information than LR3.6 PV2010. What is interesting is that the "file size" of LR3.6 PV2010 created ACR cache files are identical in size to LR4.1 P2012 created files. Below is a screen shot showing a purged cache snapshot for three (3) Canon 5D2 MKII 21Mp CR2 raw files processed first in LR3.6, and then in LR4.1 in the same order.
Cache0000000001.dat = Picture 1 in LR3.6 (530KB)
Cache0000000002.dat = Picture 2 in LR3.6 (608KB
Cache0000000003.dat = Picture 3 in LR3.6 (590KB)
Cache0000000004.dat = Picture 1 in LR4.1 (530KB)
Cache0000000005.dat = Picture 2 in LR4.1 (608KB)
Cache0000000006.dat = Picture 3 in LR4.1 (590KB)
What is more interesting is that the ACR cache .dat files are not being updated after making multiple changes to the images in LR3.6 and/or LR4.1 Develop module, only the 1 KB 'Index.dat' file is updated. I had always thought that changes made in the Develop module were updated in the ACR cache, but apparently that's not the case. I went back and hit 'Auto Tone' on each of the pictures, with no change even after zooming in to 100% on each picture. I also tried switching to the Library module and back to the Develop module, hitting 'Reset' on image, and repeating the same 100% viewing. You can see below that the 'Date Created' for the .dat image files is same as the 'Date Modified' (i.e. NOT modified), only the tiny 1KB 'Index.dat' is updated.

Adding ram to mid-2009 Macbook Pro - 4gb vs 8gb?

I want to add ram to my mid-2009 Macbook Pro. It currently has 2gb ram. Any thoughts of whether I should upgrade 4gb or 8gb ram? It has a 2.26ghz intel core 2 processor. I only use the computer for internet and the occasional document editing.

If your needs are that modest, then 4 GB is fine. However, Mavericks is designed to use as much RAM as is available, and so more RAM is always better.
If I were you, I would put 4GB of RAM in, and then buy an SSD to replace the hard drive. You will be surprised how much faster it will be! It's the best way to extend the useful life of a older Mac.

I would opt for one 8 GB stick so you would have 10 GB. total. This says really no practical advantage in dual channel memory

8GB of RAM Installed, only 4GB detected/used by BIOS/Windows 7 (with P67A-GD55)

Let me start off by saying that I'm not very good with computers. At all. I know a little bit about them, but I am by no means an expert. That said, I have 8GB of RAM installed on my motherboard, spread out across 4 sticks. However, upon looking at my BIOS and my Windows Resource Monitor, it declares that I only have 4GB of RAM installed and usable. This is what I know so far:
- This issue has been prevalent as long as I've had my computer, and by extension my motherboard and my RAM sticks, so this issue isn't recent.
- I do have a 64bit version of Windows 7. I've checked and double-checked, and I'm 99.5% positive that it is.
- Speccy, a 3rd party program designed for checking system specs, declares that I do, in fact, have 8GB installed.
- I don't think that the RAM is bad because the BIOS still does pick up on different statistics of the RAM that are in the slots; it just fails to register the actual fact that they're there.
System Specs:
OS: Windows 7 64bit SP1
CPU: Intel Core i5 2500K @ 3.30GHz
RAM: Patriot PSD32G133K 4x2GB DDR3 @ 498MHz
Motherboard: MSI P67A-GD55 P67 LGA 1155
HDD: 977GB SAMSUNG SAMSUNG HD103SJ ATA Device (SATA)
Optical Drive: LG DVDRAM GH24NS50 ATA Device
GPU: AMD Radeon HD 6870 1GB VRAM
PSU: Cooler Master 750 Watt
BIOS Version: E7681IMS V1.5
Now this is where it gets interesting: My motherboard has 4 DIMM slots for the RAM, and the motherboard (I assume by default) works in dual-channel mode. This means that DIMM 1 and 3 work together and so do DIMM 2 and 4, which most of you probably understand. However, filling up all 4 slots only gives me half the RAM. So I remove the RAM from slots 2 and 4, and it results in all 4GB of RAM being detected. Then, I add in each other RAM stick one at a time, and it fails to register both. So I remove the RAM from slots 1 and 3, and keep the RAM from slots 2 and 4, and it ends up in all 4GB being registered.
I feel like the answer should be directly in front of me, but from endless Google searches and posts on other forums, I have ended up at a dead end. I'm completely clueless, so I could really use some help.
Any and all help would be appreciated.
Also, if this is the wrong forum for this, feel free to move it wherever.

What is your current UEFI/BIOS Version?
The usual cause of such problems is (apart from bad memory slots or a defect of the processor's memory controller) a contact problem between the boards CPU Socket contact pins and the CPU's contact pads. Broke or bent pins are one explanation, in other instances a heatsink that is fastened to tight can also cause such issues.
I'll have the BIOS version up in a moment, but I'll see about diagnosing if one of those problems might just be what is my problem. Any tips on doing that?
Also, BIOS version is up in the OP now.

Can I upgrade my RAM from 4GB to 8GB for my MacBook Pro 13(early 2011 2.7GHz)? And how much would it be?

Can I upgrade my RAM from 4GB to 8GB for my MacBook Pro 13(early 2011 2.7GHz)? And how much would it be?

you can upgrade to 16GB if you wish to do so...
average price for 8GB 1333MHz DDR3 is around $50 - $75 depending on the brand.
why not spend $100 and go with 16GB 1333MHz from Crucial or Corsair.
you can get them from Amazon.com or newegg.com
see image below with 16GB Patriot Mac Series 1333MHz for $100.

Why won't my macbook pro accept both 4gb Ram, It will only use a 4gb and a 2gb?

I have a mid 2009 2.6 Ghz 15" macbook pro, and recently purchased two samsund ddr3 4gb 1600hz 204 pin RAM. I removed my two 2gb standard Ram from my macbook pro, and inserted the two 4gb Ram. When I turned the computer one it began using its 3 beep sequence as if the Ram fail, so I removed one 4gb Ram and reinserted a 2gb Ram and the computer started. It said I had total 6 gb ram. I am wonderind why It won't accept both of the 4gb Ram.

Exactly what Kappy and Stedman1 states.
The RAM you purchased is way out of specs for what you need.
Go and return or exchange them for either a set of Crucial, Corsair, Mushkin or Kingston (non value) RAM.

I want to upgrade my ram from 4GBs to 8GBs, can you help me?

Dear Apple company,

This is a customer forum, and not Apple folks. If you wish official or formal Apple assistance, please call Apple directly or visit your local Apple store, or check directly with an Apple reseller.
I don't immediately see a MacBook5,4 around, but I do see a Apple MacBook Pro Core 2 Duo 2.53 GHz 15" model MC118LL/A Mid-2009, and that configuration does reportedly support up to 8 GB of memory per the Apple Specs.
Apple might not stock or offer memory upgrades that far back (but do ask them), though I'd expect various third-party memory providers will likely still have some 4 GB 1066 MHz SO-DIMM DDR3 memory sticks around.
But if yours is really a MacBook5,4 model here — the closest I can find is a MacBook5,2 — then ignore this.

Can I upgrade the ram memory of my Macbook air from 4gb to 8gb?

Anybody knows if I can upgrade the ram memory of a Macbook Air from 4gb to 8gb?

Welcome to Apple Support Communities
The memory in the MacBook Air is soldered onto the logic board, so you can't upgrade RAM after buying your computer. It's important to buy your MacBook Air with the amount of memory you will use because you won't be able to install more RAM

Can I update the ram in a 4gb MacBook Air to 8gb of ram?

Hi I'm looking at buying a MacBook Air and I want to know if I could update a 4gb ram to 8 gb of ram MacBook Air

You can select 8GB of RAM in the MacBook Air if you configure the MBA with the additional memory at the time you order your MBA from Apple. You cannot upgrade the memory after purchase.
Regards.

G62 6GB (4GB x 1+2GB x 1) RAM instalation issue

Hello Sir
I have HP G62 with 3GB (2GB x 1, 1GB x 1) RAM factory istalled. Now i wanted to upgrade it to 6GB (2GB orignil and 4GB new DDR3 purchased RAM), installed it. But laptop is not starting just on power on fan sound heared and gone and its gone again and again.
what should i do please suggest me
Thanks

Hello Suhaib,
Here are few things you can do.
Interchange the RAM slots could resolve the issue.
else check the RAM by doing this: Insert the 2GB RAM and check if the computer turns ON fine. Then insert the 4GB RAM and check if it turns ON fine. Do this on both slots to check if the slots are working too..
Another way is by running the Memory test from computer's UEFI.
Cheers..
Wish you luck,
