Hello. I recently found out the my CPU (Ryzen 1500X) has been running at either 3504 or 3503MHz, always different when i turn on my pc. This started happening when my cousin went on my pc and overclocked it to 3800Mhz, perfectly knowing I have the stock cooler and with little thermal paste on it. I just want to know if it's normal, as ever since then my pc has been running sluggish, even after upgrading to a 1070ti. Someone please tell me whether this is normal. Thank you.
