My wife has an old laptop that is slow, it had two memory slots, and only one had 4GB in it. After studying the existing one and some Googling, this one matched the best. So I got one of these on sale, installed it, and it works perfectly. Nice upgrade and speed improvement for the laptop. With Windows 10, you need more than 4 GB total. So I would recommend this, good price.

Works great with my new NAS which came with 4GB of cheap A-DATA memory so these seem to be compatible with them (so far, only had them for a day). Works.

No complaints, not looking for anything high performance.

I've always liked Kingston, not the most cutting edge, but always reliable - saves me from running memory tests and troubleshooting - just works.

N/A

It appears to not be compatible with Intel's NUC PC (NUC6CAYH) I get a density error on boot even with the latest firmware installed. I have reached out to Corsair for more info.

Recognized immediately

None

Used in my QNAP TS-251+ NAS. Bought two sticks from MemX to up my RAM to 8GB from the factory 2GB. Works great. The NAS recognized the RAM immediately with no issues.
