AMD Ryzen – no cold bug? Speaking of Ryzen, we also have a very interesting piece of information from HardwareBattle. The following photographs allegedly show Ryzen CPU being tested with liquid nitrogen on X370 Racing GT7 motherboard. If you look closely at the photograph below, you will notice a yellow multimeter, which shows temperature reading of -29C. Since the monitor is displaying Windows logo, we can assume that the system is working, and therefore, the cold bug is not present on this platform.
