Crucial 8GB Single DDR3 1866 MT/s (PC3-14900) SODIMM 204-Pin Memory - CT102464BF186D

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!

Very good quality, working fine no problems so far

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 :)

Gotta say I didn't think I would have the best luck because all YT reviews showed same manufacture Ram purchased for second slot. This was cheaper alternative and man oh man this card (8gb) snapped right into place. I ended up switching the old 2gb Ram card from first slot into the secondary slot instead.All together I went from 2gb to 10gb (really 9.66gb) Ram and noticed the change instantly. Before I couldn't run YT with other tabs open like Playbooks (no video) without the freezing and asking me to close session after 10min. But when I put in the new card I instantly opened 20 tabs and ran YT with no problem. Even tried Netflix and two tabs with YT(YouTube) in the background paused while watching in another tab and it ran flawless.. In order to see the changes I downloaded the Cog extension from the website because there isn't no way to see Ram in settings on the device. All in all get this card if you have a First gen Chromebox and make sure it is the CT10246BF186D for correct model number for installation. Some will say you don't need this much RAM but who are we kidding with Chrome using so much CPu and Ram to run programs. I am thinking of getting another 8gb to increase to 16gb but we will see

Not a 1866 speed I can run. Slower than other 1600 sets I have. But it is so easy to return. So no harm to try.

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.

Delivery on time, kits laptop perfectly, easy to install.

I used this to upgrade the ram for my Synology ds218+It seems to be working ok.I first added the ram, turned on the synology, and its blue light blinked constantly. I waited for like 15 mins and nothing happened. I tried disconnecting the ram, carefully connected it again, made sure it was well connected, and rebooted the nas. It booted up in about 3 minutes and it's been working well so far.
