      Crucial - DDR4 - 16GB - SO-DIMM 260-pin - 2666 6/26/2020 6:19:37 AM

      Pros: Plugged it in -- works fine

      Overall Review: Speeds up your laptop .. best if you have 2 (memory should always be used as a single stick or paired with an identical stick. Mixed sticks of memory don't always work together.

      Great Memory 6/14/2020 1:34:53 PM

      Pros: Works out of the package.
      Been using it for a couple of days now with no problems.
      Crucial memory has always been good for me.

      Cons: none

      Overall Review: I would defiantly recommend this to anybody that is looking to upgrade to more memory.
      Have 32gb's in my main laptop now. Really notice the difference that it makes.
      All of my auto-cad programs work alot faster thanks to this upgrade.

      Perfectly fine laptop memeory 6/5/2020 5:37:09 PM

      Pros: -Single DIMM allows for upgrading in the future. Not like that's a high priority though.
      -Cheap
      - 16GB is enough memory to game and multiple memory hogging apps like Chrome

      Cons: - 1x16GB means laptops that rely on integrated graphics will have a bottle neck

      Overall Review: Bought this to upgrade a lower end gaming laptop that only came with 8GB memory. Laptops with integrated graphics might want to buy 2x8GB.

      Memory Failed today 6/4/2020 11:03:23 AM

      Pros: Worked for a few days

      Cons: The memory died. I put my old memory back in and the computer booted right up.

      Overall Review: I would not buy from the seller again (Ram-Store). The delivery took over 1 month and the memory only lasted a few days. Super disappointed.
