Crucial 4GB Single DDR3/DDR3L 1600 MT/S (PC3-12800) Unbuffered SODIMM 204-Pin Memory - CT51264BF160B

I bought this Crucial 8GB DDR3 RAM to upgrade an older laptop that was running slow. Installation was simple, and the system recognized it right away with no issues. After upgrading, the laptop runs noticeably smoother. Programs open faster, multitasking is better, and it doesn’t freeze up like it used to. It made a bigger difference than I expected for such a simple upgrade. The RAM arrived well packaged and works exactly as described. If you have a compatible laptop and want an easy performance boost without replacing the whole machine, this is a solid choice.

Exactly as described, works perfectly. No issues at all. I got this as part of an upgrade project for an old HP Pavilion that is on the verge of retirement. It's been my favorite device for creative writing and all around word processing for years (original manufacture date is 2016-ish) and I hate to let it go without a fight. There was some confusion and conflicting information as to whether this particular model could or could not be upgraded from 4gb to 8gb; so I took a chance... I'm glad I did. Works great. Very easy to pop-in as these old laptops had the access panel on back. There's a noticeable difference in performance. Great product. Very happy with it.

My order arrived two days before its promised delivery. The RAM slid easily into my then-4G Asus R510C laptop which came up as a 12G laptop. No fuss, no muss, no bother. Enjoy!

This Crucial 4GB DDR3/DDR3L RAM stick was an easy and affordable way to give my older computer a boost. Installation took just a couple minutes — popped it in, powered up, and it was recognized right away. The speed bump made a noticeable difference for everyday use like web browsing and light photo editing. It runs cool and stable with no issues or crashes. If you’ve got an older system that needs a little extra life, this memory upgrade does the trick without breaking the bank.

Delivered fast and product worked great, thanks so much and well packaged.

Works just fine with the second stick after the first stick was damaged in shipping. As the shipping concerns that resulted in the first stick arriving damaged (flexible padded Manila envelope instead of cardboard) were not addressed in shipping for the second stick, no 5* review. Probably should be a 2-3* just due to the shipping concerns, but the prompt Customer Service response was very nice.

This memory works great in my Alienware M17x-R2 laptop (Intel Core i7 Q740 1.73GHz, *8MB DDR3-1600, NVidia GeForce GTX 285M-1GB, 2 x Samsung 640GB SATA 7200RPM HDD-RAID1 configured, and WD Elements 1TB eSATA HDD). I usually try to give informative unbiased reviews unless the product is trivial, like cables and novelty items. Sometimes my reviews can be a little wordy, but I do it mainly to help novice to intermediate users. This particular review, became more of an Alienware review than it is about the memory. I any case, if you are an Alienware owner, you should know this memory will work for you. The improvements I've noticed by upgrading from 4GB (DDR3-1333) are small at this point, but significant since I'm no longer having crashes from insufficient RAM particularly when I switch between log-ins. I'm running a lot of peripherals and multiple Operating Systems; Windows 7 Pro SP1 64bit, Red Hat Fedora 20, and with MS Virtual PC 2007, I'm using XP Media Center Edition 2005 SP3 32bit, Vista for Business SP3 32bit, and 7 Home Premium SP1 64bit. I know this system is compatible, but I haven't installed Windows Pro 8.1 64bit yet and I'm still not sure if I want to. I use this system for both gaming and as reference with desktop support calls, which is why I use two versions of Windows 7 and probably should add 8.1. The boot time has improved moderately for each of my operating systems, in some cases only by a few seconds which I attribute to my multi-boot configuration. Load times for some software under Windows has also improved, as with Adobe Photoshop CS5, and The Sims 3. Virus and malware scanning time has been cut down by nearly half the time. Since this system memory bus can only support 10666MHz, I am not seeing any changes in benchmarks due to the 12800MHz capable RAM upgrade, nor did I expect to. The memory is perfectly stable at the slower rate. Windows Index Rating also remains the same, and because Linux has low overhead system requirements - it's still just plain fast. I would have bought the 16GB kit, but I was getting conflicting, false, or misleading information about the maximum limits from my owner's manual and Dell technical support. The manual says 8GB and I have 3 different answers from Dell's staff who stated a) ...your system was delivered with the components it was designed to support... it took several tries for me to understand the accent before I realized he was implying it cannot be upgraded at all, b) The system will support up to 16GB, providing you have updated the BIOS to version A12, however, that was erroneous because the last firmware release is A10, and c) Windows only supports up to 4GB of RAM... which is argumentatively true under a 32bit environment and XP, but I'm mainly running W7 64bit so the response was irrelevant. Other sources claim it WILL support 8GB and may or may not support up to 16GB. I was not willing to risk the expense and hassle of finding out first hand and went with 8GB based on my manual and the fact that it was the largest kit offered on the Dell website for the M17x-R2. I've used Crucial Memory in several computers over the past years and have always had excellent results. The reliability has been unsurpassed by other makers. Its stability has given me and my clients months of run-time without failure in servers, desktops, laptops, and even printing devices. I hope this helps.

Works great. No issues so far.
