AMD says overclocking blows a hidden fuse on Ryzen Threadripper 7000 to show if you’ve overclocked the chip, but it doesn’t automatically void your CPU’s warranty::AMD explains the hidden fuses behind Ryzen Threadripper 7000 processors and how it will handle warranty claims.
Yes, and when there’s little demand for good bins and strong for bad bins then the good bin is sold at the price point of the bad bin. Which happens quite rarely nowadays as manufacturers know their yields and the market and set price points accordingly.
Really unless you have a bottle of liquid nitrogen at hand you should just stay away from the overclock settings alltogether in currentyear, especially with AMD: If you want to get more out of your CPU get a good cooler and a board with good VRM which will allow it to boost higher for longer. PBO invalidates the warranty, it doesn’t void it, meaning that if the CPU misbehaves, crashes etc with PBO on AMD couldn’t care less but if it doesn’t work properly when you return it to stock settings then you have a warranty case. With those overclocking settings OTOH you can enter parameters that might right-out kill the CPU, parameters that PBO will stay away from.
