Reddit reviews Corsair CMSA8GX3M2A1066C7 Apple 8 GB Dual Channel Kit DDR3 1066 (PC3 8500) 204-Pin DDR3 Laptop SO-DIMM Memory 1.5V, Beige

I have a MPB 2009 13 inch, and just upgraded the RAM…it definitely opens apps & folders/UI's faster.

THIS is what i bought; popped the back off, pulled the old RAM out, popped the new ones in, voila.

Check your specs first & make sure it's compatible, and watch a Youtube video or two on it before you do.

10.6 is obsolete, no longer supported, and insecure because security updates are no longer being provided.

Please update your Mac. You will even get longer battery life out of it. The cost is $0.

You will also solve a bunch of other problems, much like this one.

If you feel that the machine isn't running as quickly as you would like, upgrade the RAM. This will replace the RAM you currently have in your machine and will take it to its limit, and will very greatly increase performance of your machine.

You have a lot of life left in your Mac with these two steps (keeping it up-to-date and maxing out the RAM).

To use the newest Chrome on Mac, you'll need OS X Mavericks 10.9 or later.

You can upgrade to 10.11 (El Capitan). Sadly, this will most probably slow down your computer in its current state. Like /u/Nera2626 said, you can upgrade the hardware as well, which will help with the speed on the newer OS versions. The maximum memory your laptop accepts is 8GB of PC3-8500 DDR3 1066 MHz (SO-DIMM) RAM. An SSD wil further increase speed.

Edit: Not really sure where you're from, but here's a list on Amazon:

https://www.amazon.com/SanDisk-240GB-SDSSDA-240G-G26-Newest-Version/dp/B01F9G43WU/ref=sr_1_4?s=pc&ie=UTF8&qid=1498659178&sr=1-4&keywords=ssd

So you could be back on track for less than $150 if you know someone that can help you install it.

Well, there are two upgrades you can add to the iMac: You can add more RAM to it and upgrade the internal HDD to an SSD.

As for the RAM:

The iMac late-2009 with 3.06 GHz Core 2 Duo supports up to 16 GB RAM (4 x 4 GB RAM modules). It has four RAM slots, meaning four RAM modules in total will fit in. A higher total amount than 16 GB RAM won't work due to a limitation in the logic board.

The iMac late-2009 needs RAM that matches the following specification:

PC3-8500 DDR3 1066 MHz, 204-pin

Here are some examples of RAM modules that work flawlessly in the iMac late-2009:

• https://www.amazon.com/DUOMEIQI-PC3-8500-PC3-8500S-Unbuffered-Compatible/dp/B071WFG1BC/
  
• https://www.amazon.com/Timetec-PC3-8500-1066MHz-Upgrade-MacBook/dp/B01N35UIYR/
  
• https://www.amazon.com/Corsair-CMSA8GX3M2A1066C7-Channel-204-Pin-SO-DIMM/dp/B00505EZYW/
  
• https://www.amazon.com/TECMIYO-PC3-8500-PC3-8500S-Unbuffered-Notebook/dp/B07KQ2B9D8/
  
  You may find information online which states that your iMac late-2009 only supports up to 8 GB RAM (2 x 4 GB RAM modules), but this is outdated information! As 8 GB RAM modules were not commonly available back in 2009, Apple could only test with 2 x 4 GB RAM = 8 GB RAM. When 8 GB RAM modules became available, users found out that the actual maximum RAM capacity this machine supports is 16 GB RAM, this is also being confirmed by the Amazon reviews of the modules I suggested. Apple never went back to update their info, so the wrong 8 GB RAM figure still swirls around.
  
  The RAM upgrade is very easy to do, you can take a look at the procedure here:

  As for the SSD:
  
  Your iMac late-2009 supports any SSD that matches the following requirements:
  
  
• 2.5" form factor
  
• SATA3-compatible
  
  Here are some examples of such SSDs:
  
  
• https://www.amazon.com/Samsung-860-EVO-500GB-SSD/dp/B07937HDJM/
  
• https://www.amazon.com/SanDisk-Ultra-Solid-State-SDSSDH3-2TOO-G25/dp/B071KGRXRH/
  
• https://www.amazon.com/Crucial-MX500-500GB-NAND-Internal/dp/B0784SLQM6/
  
• https://www.amazon.com/Blue-NAND-500GB-SSD-WDS500G2B0A/dp/B073SBZ8YH/
  
  Choose a capacity that meets your needs. Furthermore, the iMac late-2009 will need an adapter, as it currently has a 3.5" HDD inside. SSDs are 2.5" in size, however, which is why such an adapter is needed:
  
  
• https://www.amazon.com/Sabrent-Desktop-Converter-Mounting-BK-PCBS/dp/B00UN550AC/
  
  You will also need a new thermal sensor. The thermal sensor that is currently in your device is inseparably connected to the current HDD. The thermal sensor measures the temperature, and if you insert the SSD without also inserting a new thermal sensor, the fans of the iMac will be running constantly and at full speed, since the machine is no longer able to read out the temperature. This OWC kit contains such a thermal sensor:

  Please take note of the fact that the HDD -> SSD upgrade, contrary to the RAM upgrade, is very hard to do. it requires a partial disassembly of the device. If you don't think that you can pull it off yourself, then consider letting a Mac repair shop or similar do it for you. You can take a look at the procedure of the SSD upgrade here:
  
  
• https://www.youtube.com/watch?v=Y6hRZwgU5sU
  
  If you want to keep any of the data that is currently stored on your HDD, I suggest you create a Time Machine backup to some external drive. Once the SSD is in, macOS can be restored via Internet Recovery:
  
  
• http://osxdaily.com/2018/10/10/how-reinstall-macos-mojave/
  
  Once macOS is reinstalled, you will be asked whether or not you want to restore from a Time Machine backup during the setup procedure.

  DOES THE UPGRADE MAKE SENSE FOR YOU?
  
  Well, macOS 10.13 High Sierra from 2017 is the highest macOS version your iMac supports. High Sierra is going to lose security support from Apple in autumn 2020. So, for security reasons, unless you want to turn the iMac into a Windows or Linux device, it wouldn't be worth it. Also, there is a vast CPU performance difference between your current iMac and even the base model iMac 21.5" 4K 2019. Take a look at those Geekbench scores measuring CPU performance:
  
  iMac 21.5" late-2009, 3.06 GHz Intel Core 2 Duo E7600 Dual Core:
  
  1869 Points (Single-Core Score)
  
  3109 Points (Multi-Core Score)
  
  source: https://browser.geekbench.com/macs/229
  
  iMac 21.5" 4K 2019, 3.6 GHz Intel Core i3-8100 Quad Core:
  
  4720 Points (Single-Core Score)
  
  14111 Points (Multi-Core Score)
  
  source: https://browser.geekbench.com/macs/442
  
  As you can see, even the current base model iMac 21.5" 4K 2019 totally blows your current iMac out of the water. Even with RAM and SSD upgrade, you won't be able to match the speed of any current iMac. That being said, if you opt for a newer model, consider adding an SSD to it at the time of purchase. The HDD can still be upgraded to an SSD even in the current iMacs 21.5" 4K 2019, but the procedure is still a mess. Do yourself a favor and at least add a small SSD to it when configuring it at the Apple website.

Looks like your laptop series (not the exact model, since you didn't mention it, but most of them are same in this series so there shouldn't be a problem) can support 2 * 1066MHz DDR3 RAM up to 8GB in total so I would recommend you to buy this as RAM. (Don't worry, it says it's compatible with Macbook etc. but it's just because that kind of RAM is more commonly used in these models). As SSD, I would suggest this which I currently use on my PC aswell (HDDs have a common size so it should fit. Not sure if your laptop supports 2 HDD slots tho so if there is no more HDD slot, then you prob. need to swap SSD with that so I would suggest buying a higher storage model like this one.)

I don't think that is the RAM you want for the 2010 MBP. That's 1600hz, and your computer uses 1066.

The following link isn't intended to get you to purchase the RAM from this vendor - rather, just use it to help track down matching and appropriate RAM on Amazon.

So using the above as a guide, you may try something like this if you want to get it from Amazon.

Thank you for your response. Here's what I got from searching for "shutdown" without the quotes in Console.app

I couldn't find any ".Panic" results under System Diagnostic Reports however.

The ram I used was a Corsair 2 x 204-pin SODIMM DDR3 1066 MHz CL7. They are two 4GB sticks that are linked below. I guess these are the wrong ones?

http://www.amazon.com/Corsair-Channel-204-Pin-SO-DIMM-CMSA8GX3M2A1066C7/dp/B00505EZYW/ref=sr_1_1?s=electronics&ie=UTF8&qid=1420367056&sr=1-1&keywords=Corsair+2+204-pin+SODIMM+DDR3+1066Mhz+cl7

I went to Crucial.com and ran their scanner, should I return the ram I installed and get the ones they recommend instead?

So get Amazon to send the right one maybe?

If the replacement is shit too, then try this: http://www.amazon.com/Corsair-Channel-204-Pin-SO-DIMM-CMSA8GX3M2A1066C7/dp/B00505EZYW/ref=sr_1_2?s=pc&ie=UTF8&qid=1412614730&sr=1-2&keywords=1066mhz+ddr3+sodimm+pc3+8500

OWC is usually more expensive for no reason.

I think I found the closest thing to a guide I have for the RAM switch I made: http://www.zenbookforum.com/threads/diy-how-to-upgrade-from-hdd-to-ssd-on-zenbook-ux302-and-other-models-most-likely.2827/

Also, I found the RAM I believe I used: https://www.amazon.com/Corsair-CMSA8GX3M2A1066C7-Channel-204-Pin-SO-DIMM/dp/B00505EZYW

As far as I remember, the motherboard has 2GB installed that can't be removed and it comes with 1 slot filled with another 2GB. I therefore uninstalled the 2 in the slot and substituted two 4GB.

Lastly, would a downgrade of OS help out with some of these problems, or is it not worth it?

let's break it down:

• $65 240GB ssd for Kingston v300 or go bigger or get a better brand
  
• $40 8GB 1066mhz ram
  
• $40 6000mAh battery
  my original battery holds about 3 hours of a charge after 6 years
  
  or get a chromebook, toshiba chromebook 2, 12 hours of battery life, i3 proc, 4gb ram, perfect for browsing / email / google docs / remote into desktop at home and do the heavy lifting there
