💻 A-Tech 8GB DDR3 1600MHz SODIMM RAM Upgrade Kit for Laptop, Notebook & AIO Computers - 2x4GB PC3-12800 (PC3-12800S), CL11 Non-ECC SO-DIMM 204 Pin Review

A-Tech memory modules did not come new and with damaged contacts. When I properly installed them on my laptop, the system refused to boot and beeped. My laptop is a mobile workstation and supports up to 32GB of 1600MHz DDR3 SODIMM memory in quad channel mode. After removing the A-Tech memory modules and using standard RAM; my computer will publish. I'm pretty sure those A-Tech memory modules damaged my computer's RAM slots and caused a short circuit. I am completely outraged; will send them…

I installed a Lenovo Ideapad G575 with 4GB RAM. With Windows 10 I needed a more responsive computer so I ordered and added an 8GB kit. I have a lot of experience upgrading computers and memory, but this was the first computer where the computer would not boot after replacing the original two memory modules with new ones. Individually they worked well. I ended up having to remove the battery and power cord and press the power button for about 1 minute. Then, after reseating the battery and power

This happened ahead of schedule! It is clearly marked, I received exactly what was stated. Installation was difficult. As I work on computers, some prior knowledge was required to upgrade, but for those inexperienced, use the link on your computer: click the Apple logo in the top left corner. Click About This Mac. Select the Storage tab. In the lower-right corner of the window, click Memory Upgrade Instructions. Follow the instructions and you shouldn't have any problems. One caveat: When…

Works great in my early 2011 Mac Book Pro. I can see a difference when I have multiple programs or 20 tabs open in my web browser. I'm glad I upgraded from what was on my Macbook. It was very easy to install. I followed Apple's "About This Mac" instructions under the "Storage" tab - the bottom button labeled "Upgrade Storage Instructions".

Didn't work with my system. I'm a techie and I've tried everything. If you're trying to call support, you'll need an order number. Then leave a message and never call back. If your system reads it, great. My Sony Vaio laptop with Win 7 did not work. Cannot change BIOS or Windows settings to fix the problem. It would be nice to return it but I can't contact the company. I took another brand, there were no problems.

In my experience the part number CT2KIT51264BF160B in this product description is incorrect. (4GBx2) DDR3L 1600 MT/s (PC3L-12800) 204-pin SODIMM memory - direct CT2KIT51264BF160B that worked great (about $20 more than the first, so my first try). If you search Crucial's reviews for the HM55, you'll see confirmed compatibility reports for the rather specific 256Mx8bit "modular package" that this chipset requires.

I have a MacBook Pro 13" Mid 2012 that came with 4GB of RAM and it became so slow it became unusable. It seemed like every time I tried to use it I got a spinning wheel and had to wait an unreasonably long time to be able to do anything. Or I would have to reboot first to even have a chance to do anything. I started pricing new computers and decided to upgrade the memory. I bought them, found a video showing how to install them, put them in within 5 minutes and it was like I got my Macbook…

Delivered on time, beautifully packaged securely, works as installed. The only thing it really improved was my Windows performance rating "computations per second" to about 7.1 (about right, but I can't remember if it was right or 7.0) and that's it pretty much the maximum value it can have. The other stats haven't gone up much though, other than I think the graph has gone up to 5 instead of 1 before (this is very important as the graph calls for the ball). The memory tester showed that the…
