Timetec 16GB KIT(2x8GB) DDR3 / DDR3L 1333MHz PC3-10600 Non-ECC Unbuffered 1.5V / 1.35V CL9 2Rx8 Dual Rank 204 Pin SODIMM Laptop Notebook PC Computer Memory RAM Module Upgrade(16GB KIT(2x8GB))

I have a Dell XPS17, from 2011. It's got an i7 CPU and is still a very good PC, except that it had only 8GB RAM (two 4GB SODIMMS). Firefox in particular used up a lot of that memory, causing swapping and slowness. I wanted to double the RAM from 8GB to 16GB by replacing the existing two RAM modules with two 8GB modules.I contacted the seller to be sure that I was buying the right product. Mark from Timetec replied quickly. He asked for additional information to be sure he knew exactly which model laptop I had, and determined that this was the right one. I felt very confident buying from Timetec.The install was simple. After removing one screw, I had access to the RAM (and also the two HDDs). The memory modules were easily removed and replaced with the new ones. When I started the laptop, it started as normal - no errors nor any indication that the amount of memory had changed. But when I checked, the memory was indeed doubled. I've had it for a couple weeks now and have had zero issues. The laptop is noticeably faster now. For $20 this was a very wise investment.

Fit the 204 pin slots and worked as expected. Upgraded from two 2rx8 PC3 10600S 4gig ram chips to two 8 gigs.

Why did you pick this product vs others?:Sped up my old laptop with new life!

Working perfectly! Exactly as described.

I have a dell latitude e6420 with 4 gb of memory and bios of A04 running windows home 64 bit version.From reading other reviews I found I needed to upgrade my bios to A25 and although a little hunting is necessary, I was able to get it done on the Dell support website. I also realized that I needed the 64 bit version which I had been using but it was the home version not Pro which is what was in the review. Once that was all ready, I ordered the memory and it was easy popping out the old memory and adding the new 16 gb and up and running quickly. Although the machine is still a little slow in booting, once up it is running great. Before upgade the machine took forever just opening excel or word files. Now it snaps.Memory came in a sealed package right away and seemed of good quality and worked right out the get go. Very satisfied with the results. I only use the laptop once in a while and it was so slow and sticky that I was thinking of replacing it. But now it works reliably and reasonably well and don't need to spend the extra $700 or $800 for the replacement.

Used one of these to double the RAM in an old laptop along with an SSD. The laptop felt like new again and ran so much faster than before. Make sure it is the right type for your laptop and that you've got room for it, unless it's going to be a replacement stick.

Shipped on time (although system said it may be late). Easy installation immediate result in performance but got it for 1 day so can't really say if it lasts. The only thing that surprise me is that 8 gig of DDR3 1333 Mhz costs just about as 8 gig of DDR4 2400 Mhz...

Client has a Dell E6320 with only 4 gigs of ram. I ordered this 2 x 8 (16 gig total) set up and it works great. The system saw the 16 gigs immediately. Great pricing as well.
