16GB DDR4 2666MHz PC4-21300 Unbuffered Non-ECC 1.2V CL19 2Rx8 Dual Rank 260 Pin SODIMM Laptop Notebook Computer Memory RAM Module Upgrade (16GB)

This memory module was well packaged and has performed well in use and it did not cost the earth.

What I purchased (Because Amazon doesn't always make this obvious when it comes to reviews): 32GB KIT (2x16GB) DDR4 2666MHz PC4-21300 Unbuffered Non-ECC 1.2V CL19 2Rx8 Dual Rank 260 Pin SODIMMI spent far too long looking specifically for a Dual Rank kit, after seeing how performance can be severely impacted by using Single Rank sticks. The majority of manufacturers now seem to be cheaping out by not actually saying which rank their sticks are, but not Timetec who listed it as a feature.I used this kit in my Dell Latitude 5401 (Intel Core i7-9850H) and it works absolutely fine. No major increase in overall system performance considering I originally had a single 16GB 2666Mhz Dual Rank Samsung stick, but I didn't buy more RAM to increase performance! I do a variety of memory-intensive tasks like video editing in Da Vinci Resolve, Full-Stack development and fairly high density Cubase projects, so I'll take as much RAM as I can get.I have attached CPU-Z screenshots, hopefully you will find them useful if you know what you're looking for :)

The first set of 32g ram was defective as it was only showing 16g Ram in Windows System. After doing process of elimination it was one of the 16g Ram that was defective so returned for a refund which was given very quick. Ordered another set 32g (2 x 16g Ram) & all 32g ram is now showing in Windows. Excellent ram & it's dual rank. Would recommend.

Works fine. Easy to install.

I use qnap NAS with a lot of containers and the 4GB RAM it came with was used up immediately, device claims it can only support 4GB but uses 32GB no problem

For the avoidance of doubt, this SODIMM RAM works perfectly in my NAS - giving me 18GB total, and zero warnings. Too early to tell about longevity, but RAM has never failed in any of my systems.System details:Synology 423+ DSM 7.2.1-69057 Update 4Timetec Hynix IC DDR4 2666MHz PC4-21300 Unbuffered Non-ECC 1.2V CL19 2Rx8 Dual Rank 260 Pin SODIMM Laptop Notebook Computer Memory RAM Module Upgrade (16GB)Amazon part: B07N1WZNP7

As I write this, the product is described, in part, as "2Rx8 Dual Rank". Now, for most people, dual vs single rank RAM is just a matter of speed, and generally not that important in practice. For me, it was vitally important, as this RAM was to go in a device that requires dual-rank RAM; it's specifically why I bought this. So I put it in, and the device wouldn't boot, and I took a close look at the RAM, and... "1Rx8". Single rank. For my purposes... well, it's not even heavy enough to use as a paperwight.In fact, most of the details of the RAM don't match the one advertised; it also had a higher CL and higher speed. They just threw a completely different 8GB DD4 SODIMM in a box and set it my way. Completely useless to me.

Easy to install, good product

Perfectly working

The media could not be loaded.  Not the first time I purchased Timetec Ram and I can tell you it's a great brand. It has significantly improved my system's performance. Installation was straightforward and the RAM fit perfectly. My laptop now runs faster and handles multitasking with ease. Overall, this RAM is a great value and highly recommended for anyone looking to enhance their laptop's capabilities.

Love it.

Good price point. Have been using it in my laptop for several months without any issues. Overall moving from 16G to 32G of RAM increased the speed of Windows. Personally I would have gone to 64G but this older machine could only accept 32.

Extremely happy with it. The price is great, and it was plug-and-play for my Synology 2-Bay DiskStation DS224+.I have been using it for three weeks now and have no issues at all. Brought my memory utilization significantly.
