In the 2 years that I have owned these RAMs, they have never given me the slightest problem as RAM. The speeds are exactly as stated, no issues with XMP/Expo running at 3600 CL16. I have 4x8gb modules, plugged into a PC with ROG STRIX B550-A, Ryzen 5700X, and 3070.

So why the 3 stars?
If you are looking for these RAMs, like I was, you are interested in having RGB. Unfortunately, in this case, not only with these but also with all Kingston RAMs, the software for controlling the RGB as well as their drivers are so terrible that every time one RAM desynchronizes, the PC needs to be restarted just to see if it works, and it happens constantly. I have been so disappointed that I simply wished I had spent 10 or 20 euros less to get the same ones without RGB, and every time it "breaks," I want to throw them out the window and literally get anything else.

TLDR;
Excellent RAMs, just don’t buy them with RGB.
