Patriot Memory Signature Line DDR4 8GB 2133MHz SODIMM Memory Module - PSD48G213381S

Fast shipping and does its job! My laptop was struggling and when I doubled the RAM with this DDR4 it made it run so much smoother. Make sure you know exactly what RAM you have prior to buying. I am so happy with my laptops performance once installed!! I highly recommend this to use in your laptop if it is compatible with what you are already running.

Purchased for a client and worked fine. Purchased a second (At greater cost.) a week or two later and that one was defective and would not allow system to boot. Due to another cost increase I went with another manufacturer after I returned bad unit. Defects happen so no big deal. Would buy again as long as price is right.

Works perfectly on my Asus G15 (ryzen 4800hs and nvidia GTX 2060). Total 40GB (8GB onboard + 32GB from this stick). Works like a charm, system recognized as 3200mhz

The first stick was faulty. Amazon replaced it quickly and the new one has no hick ups. Works flawless. Happy with the purchase and price paid.

Works as expected. No errors that I have seen on my firewall.

I have a Galago Pro 5 Linux laptop which is designed to be upgraded. The installation of RAM was easy.

Not compatible with HP EliteBook G4, throws errors and shows as 4GB.

This memory was at a good price point and installed easily and works great.

Added extra memory to laptop. Easy plug & go.

I cannot get the series number info for this product via tools like CPU-Z or AIDA 64 extreme, nor the manufacturing date (xx week/xx year). Well, cheaper stuff is cheap for a reason. Other than that, the spec is good as told, it could use as a dual channel with my another existing RAM (kingston) in my laptop, no problem after running AIDA 64 stress test and gaming for a while. Besides, the package is shipped by USPS so it arrived earlier than Amazon expected due to that the tracking is not updated in time. All in all, nothing to complain and it deserves five stars.
