I recently added more RAM to my system. Originally it had 16GB, and I planned to upgrade to 32GB. The RAM I purchased was identical to the ones I bought in January 2020—both 16GB (two 8GB modules) with a 3200MHz rating. After installing them, I activated XMP in the BIOS and saved the settings. The PC restarted normally. However, it didn’t restart again after booting. When I power on the machine, the fans spin quickly at first but then slow down. But once the RAM was installed, the fans kept running at full speed. After leaving it for ten minutes, nothing happened except a black screen. A friend suggested trying a CMOS reset by removing the battery from the motherboard. After restarting, the BIOS showed the RAM as 2133MHz by default. I experimented with 2400MHz and it worked fine. At 2666MHz it also stayed black until a CMOS reset occurred. My goal is to run all sticks at 3200MHz for optimal performance. Any advice or feedback would be greatly appreciated.
