I am getting tired of fanboyism to the game giving bad information about overclocking. You should not be asking just if someone is overclocking. You be asking how they verified it is a good overclock. You verify a good overclock with a stress test dedicated to that specific item.
Just for information
Every CPU, GPU and memory chip are binned at the factory. They run an algorithm into each chip with increasing speed to determine the fail point of the chip. So all AMD chips are from the same wafer manufacturing process. As are all intel, and Nvidia chips to their respective wafer process. Memory chips come from a few suppliers as there is more than one supplier who can make them. When a supplier bins a chip, they do it with a very short algorithm in comparison to the stress tests I mention here. They only ever run it for a few minutes, before they increase the speed to the next level. they do not have the time to do lengthy stress checks on anything but a few samples for batch checks. If you overclock and verify with a good stress test, then it will exceed any test the manufacturer will throw at it. It will also exceed any normal running condition.
For memory I use Karhu. Karhu was developed as a project to be better than HCImemtest. HCImemtest was the main programme used by the overclocking community at https://www.overclock.net. Which in turn was vindicated by people like “the stilt” (world champion overclocking guru) and Elmor (Asus community relations manager for AMD boards at the time of his advice posts).
A 30 minute run of prime 95 followed by a 30 minute run of Cinebench is more stress than your CPU would ever face in the lifetime of the CPU. I don’t bother overclocking CPUs anymore. It is pointless imho on today generation of Ryzen. I still run this stress test every time I update a bios revision. I do this because even running at stock does not guarantee stability.
Any overclock should also be over checked with a good sensor read out. HWinfo is usually the default now, but there are many others. With this you can check thermals and vindicate stress runs. There is no point to an overclock that is going to run exceedingly hot. It is even better if you can over check sensor reading with probelt verification and thermal readings.
So please stop this bull where anyone who overclocks is running a bad system. It simply is not true. Start asking for verification of system stability if you believe there is an issue.
