Timetec 4GB DDR3L / DDR3 1600MHz PC3L-12800 / PC3-12800 Non-ECC Unbuffered 1.35V / 1.5V CL11 2Rx8 Dual Rank 204 Pin SODIMM Laptop Notebook PC Computer Memory RAM Module Upgrade (4GB)

I installed this in an old ThinkPad T440s. I'm now running at the max 12GB using this 8GB stick. Laptop booted up fine and immediately utilized the additional RAM. Verified that it runs at 1600MHz and in Dual Channel along with the soldered 4GB that came with the machine originally. Highly recommended!

I ordered 16 GB ram came quickly for a good price I do recommend anyone buying ram makes sure their laptop is compatible with a higher ram amount otherwise it could show on the laptop that it is lower then it actually is

Si tienes una laptop de primera a cuarta generación o una mabook del año 2011, esta es la ram que necesitas

Worked right out of the package. I took an old Lenovo all-in-one computer and got rid of Windows 10 and installed Chrome OS Flex. I upgraded from the old-style hard drive to an SSD and the RAM from 6GB to 16GB. It's like a brand-new machine, and it's 13 years old. For the little money spent, I'm super pleased.If you didn't know this was "cheap" RAM, you wouldn't know. It's as high in quality of construction as any I've bought, and I've bought a lot over the years.Would definitely buy it again.

It makes my computer faster. I can use my computer for a few more years.

They are fine and work correctly, for the price I think it is a good purchase

My old laptop was struggling because I didn't have enough RAM, resulting in too much HD caching. This replacement ram was easy to install, and solved that issue for me.

Fast shipping, and great customer service. Running like a Swiss watch.Thanks!
