Crucial 4GB Single DDR3/DDR3L 1866 MT/s (PC3-14900) Unbuffered SODIMM 204-Pin Memory - CT51264BF186DJ

NOTE: I already upgraded my CPU from the stock i3 to an i5 processor*, so my computer is now about as upgraded as it can be. Upgrading a CPU is possible with this model laptop as the CPU isn't soldered to the Mother Board. The reason I upped the ram is I was running out of ram regularly with heavy video editing projects (originally had 8GB of ram).I use Ubuntu Linux (16.04 64bit) and do not know how this ram would function on this computer if it were running Windows as I do not use Windows (and very happy that I don't)... although, I would guess that this ram would work fine.This is a very easy upgrade for most laptops... just check your specific model on the Crucial website to be sure you are ordering the correct ram modules for your specific model computer to avoid the hassle of getting incompatible ram modules ;)So far I have had no problems with these ram units, and everything worked perfectly when I booted up after installing them! I am using them in a Toshiba Satellite c855-s5355 Laptop running Ubuntu 16.04 and my System Monitor shows 15.6 GB of usable RAM out of the 16 GB installed (8GBx2)... I am a happy camper!*fyi... I installed the Intel Core i5-2410M CPU @ 2.30GHz (2 cores/4 threads) which worked perfectly in my computer. However, I do not know if Windows 8 or 10 would have hiccuped with this upgrade... again, I use Linux, so it just worked in my case :)

Very good quality, working fine no problems so far

I received this item 48 hours later than expected but I still love this item. I bought these ram sticks to upgrade my Lenovo e531 which only had 4gb of ram and was definitely holding me back. My computer worked fine but operated really slow when I had multiple internet tabs open or when I was trying to use multiple applications.I received this item, unplugged everything from my laptop, disconnected the battery, removed bottom panel (2 screws), removed old ram and replaced with new ram, and reassembled the computer.My computer is significantly faster now. I was constantly pushing upwards of 100% usage of my memory but now it ranges from 25-50%. I'm writing this review, listening to a podcast on youtube, watching multiple graphs on tradingview.com in multiple tabs, and I have a couple other amazon tabs open without any issues. I can switch between these tabs without any lag like I used to get. I also saw improvement while playing league of legends. I installed this memory yesterday 7/23/18 so I can't speak about longevity but I would 100% recommend this product. It is simple to install, just be sure you don't have any built up static electricity because you can cause latent damage without even knowing it.

Today I upgraded my 2015 HP Pavilion model 13-a012cl "X360" laptop computer using the Crucial 8GB Single DDR3/DDR3L 1866 MT/s (PC3-14900) Unbuffered SODIMM 204-Pin memory chip. 8GB is the max my laptop can support. The upgrade was flawless. The difference between DDR3 and DDR4 is the number of pins on the chip that connect it to the socket. DDR3 has 240, and DDR4 has 288. Besides the pin number, DDR3 and DDR4 look physically different in length and width. Google your computer's model number or contact the manufacturer to determine which your specific model requires.My laptop is about 5 years old, and usually I have it tethered to an external 22" LG LCD monitor, so the unit functions more like a desktop box would. I thought about getting a new laptop, but opted to purchase the Cruicial RAM chip -$44, a Cruicial MX 500 1 TB 2.5" solid state drive (SSD) (CT 1000MX500SSSD1) - $120, and a new fan- $17. I also bought a Unitek USB to SATA USB-3 adapter to clone drives - $19. So for around $200, I have essentially a new computer.Numerous publications over the years have cited adding additional RAM memory as the single best - easiest - improvement one can make in improving computer perfomance. Add to that SSD and a new cooling fan, and I ought to be golden for another five years. I don't do payroll for the State of California, nor do I track license plate numbers for Bejing, so to me, this was a cost-efficient upgrade.Thanks Cruicial and Adorama for the sales and support!

I replaced the original 8GB, divided in the two slots of my Lenovo Y510P (from about 2 years ago). I use it for online school. Between word processing, and the occasional Netflix or HBO GO use I use it for Adobe Creative Cloud applications for my school classes/projects. Some stuff gets saved to the cloud (in some form) and others need to stay on my hard drive but I needed more than 8GB alone could give me, so I upgraded to 16 GB. My kid also uses my laptop for Lego Mindstorm programming (Lego robotics).It was easy enough to unscrew the back(bottom) section of my laptop and switch them out, despite finding and extra screw rolling about inside (hmm...bad quality control on Lenovo's part) that hiccup aside I put the new ones in, closed it all up and everything booted up just fine.I cannot stress enough how much, just in case, you should BACK UP YOUR COMPUTER, BEOFRE switching anything out. That way if it does not work out you have not just doomed yourself. But bottom line so you understand why I needed the upgrade and on what type of machine, yes this was and easy install (for me) and works as it is supposed to for the type of product it is. Cheers!

I ordered this 8 GB card as an upgrade to my Asus F555LA-AB31 15.6-Inch Laptop which I just bought from Amazon at a great price. The laptop had 4 GB of RAM memory but reviews for the laptop suggested an upgrade to at least 8 GB. I found a YouTube Video giving instructions of just how easy it is to install a memory card into the Asus F555LA-AB31 15.6-Inch Laptop, and believe me it IS easy! Also the video suggested that for just a few dollars more you might want to purchase an 8 GB chip instead of the 4 GB (with the 4 you would have a total of 8 GB of RAM memory). I think the 8 GB card for a few dollars more was a good decision. Now I have a total of 12 GB of RAM and in just the few days I have used it I can see a huge increase in my laptop speed!
