Crucial RAM 8GB DDR3 1600 MHz CL11 Laptop Memory CT102464BF160B

This memory was very easy to install. Microsoft operating system recognized the memory and updated the software automatically. Made my slow cheap Laptop run faster at a minimal cost.

It fits and works right every time and you never have to wonder or worry about fakes, as long as you're buying from Crucial. They have a RAM/Storage tool on their website that will show you exactly the type RAM that is required for your model. It's my go-to... I've been 100% satisfied for over 20 years.

Its ram i have had 0 issues since I installed it

Worked as expected and shipped nicely.

The product was exactly what I needed to complete the memory upgrade and there was no problem with the installation

Did not work in 2009 Macbook (white).Opposed to some online sources, the 2009 Macbook (white) will not support this. I guess it needs: 8gb of 204 pin 1066mhz PC3-8500 RAM...When I installed these both in my macbook it would not boot up, it just beeped at me.To test if it was maybe just bad RAM:1. I put just one of these 4GB in and one of the original 1GB sticks (5GB total of RAM... but keep in mind you should always balance your RAM), it will boot, but there is little to no improvement, it may even be worse. It did show that it had 5GB of RAM, proving it was recognizing the new stick.2. I did the same thing with the other 4GB stick (thinking the first stick might be bad). I got the same results with the other stick.- Although this test did not prove this was RAM was not defective, I concluded that it would still boot and recognize the 5GB of RAM that was in it.This led me to do some deeper research and I found that in fact, the white macbook does not support this ram. The specs I posted above may be the correct ones. I am not sure.Side note: I am currently running 8GB of RAM in my 2010 Macbook Pro 15" i7, and it works perfectly. Upgrading the RAM breathed new life into it and will allow me to get at least 7 years if not more out of it. A clean install of the OS (wipe the harddrive, install most recent OS onto erased harddrive, you can find instructions online) is also a necessity every once in a while. Things will run much better for you.

Purchased this memory for my Desktop computer. Arrived in great condition, and worked without issues.

My wife's Macbook Pro is getting pretty old now, and she's been complaining that it's "slow". So went through the startup processes and installed apps and removed everything she isn't using, then bought this memory upgrade.Generally speaking, Ram is either good or not. In my I.T. career I have heard of "bad ram" that causes reboots, corruption, etc, but this rarely the case where someone would notice it (more often a system just becomes "unstable" and needs to be rebooted more often or locks up/reboots once in a while). If someone is really paranoid they can use ram with Error Correction for a server (used for critical applications where errors are catastrophic), and/or test the ram to make sure it doesn't have any diagnostic errors. But in general, ram is ram and if it works it works. There's no moving parts so if you encounter issues it's far more likely to be the wrong product or poor installation than a bad piece of hardware unless you are buying from a vendor that does not test their product before shipment or knowingly is selling you bad product. That said...Installation is dead simple for my wife's old Macbook. Remove screws. Push in tabs to pop out old ram. Install new ram by pushing pins into slot firmly and pushing down to swing arm into place and lock ram. Turn on to make sure no ram error on boot and all ram recognized. Turn off and screw back panel back on. Done!All ram recognized, no errors (so far) and large applications load faster. I think my wife will really (not) notice the difference with large applications and files. In other words if she's running several apps at once and/or working with images she WON'T notice chugging and slowdown.So yes, if you have an old machine that doesn't come with 8gb of ram already, this is a good upgrade. I don't recommend upgrading to more ram than that for most people since they won't notice the difference once there's enough for all OS files to load into ram and apps to load into ram without disk swapping (paging). Beyond that you will generally know if you need more ram because you'll be a professional working with ram images, 3D editing, video editing, or something else that requires more ram to function.Interestingly most games will never require a high amount of ram unless you are running at very high resolutions (4K, etc) so leave the bigger ram upgrades to the professionals and install this upgrade to 8gb for everyday use. 4gb is too low to run a modern operation system smoothly without slowdown.
