Review on Unlocked AMD Ryzen 7 3700X: 8-Core,16-Thread Processor with Wraith Prism LED Cooler - Perfect for Your Desktop Needs! by Jiang Anson (Jiang J ᠌

I tried a lot of these processors, but once I ran into this situation. I have an Asus ROG crosshair VII hero (WI-FI) board, somehow I sold the 3700x, removed the board, installed the asus formula and 9900x on Intel and completely forgot about it. And then at work there were 2 boxed 3700x. Without hesitation, I bought them, brought them home, inserted them (the BIOS settings were saved on the board), in theory, insert the percent, press f1, load the profile and use the 3700x ryzen at 4400 MHz again. But no, the board completely refuses to start. (memory and other hardware is the previous one, which worked stably with the previous processor) green samsung 2x16GB memory at 2400 MHz, it is on b die chips with the previous processor on the same board, it worked fine at 3600 MHz. see screenshot At first I thought maybe when removing the installation I damaged it, I ran it in the memtest tests, everything is ok. I reset the bios settings, Windows boots up, the tests pass, but it only takes a little more read the voltage and frequency of the processor so everything will either boot up, but as soon as you type the password, the blue screen will immediately appear or it will not boot up at all. Put another one - the same picture. I took it out of the box, which had been lying since January 3800s, and voila everything went, all the same profile settings of 4400 MHz percent and 3600 MHz memory pass the tests perfectly. Here I was puzzled, how can 2 absolutely new 3700x processors work only in stock?
