difficult to set at 4000 MHz
The product arrived intact and within the announced timeframe.Product corresponds to the advertisement, but on an Asus TUF B550 motherboard with a Ryzen 5 3600, it cannot be pushed to 4000 MHz (2133 by default in eco mode). The system freezes and the computer runs without displaying anything on the screen or being shut down normally. I had to reboot the CMOS with a screwdriver (by shunting the two corresponding pins) and limit myself to 3800 MHz. A pity, but not catastrophic. The quality/price ratio at the time of purchase (139€) remains more than correct.
