I'm having trouble reaching 4.1 GHz with Ryzen.
I'm having trouble reaching 4.1 GHz with Ryzen.
Hi.
I noticed an unusual occurrence while overclocking the Ryzen 5 2600.
It remains stable at:
-4,0 GHz and 1,3125v (72-77°C in OCCT)
-4,05 GHz and 1,3625v (around 80°C in OCCT)
However, even at 1,40V it doesn't stay stable at 4,1 GHz.
Could this be a faulty Ryzen processor or is there something wrong with my setup?
My details:
CPU: Ryzen 5 2600
Motherboard: Asus b450-f gaming
PSU: Corsair VS650
Appreciate your help 😊
I wouldn't choose to use a Ryzen 2K running at 1.4V. The difference between 4.1 and 4.0 GHz is just 2.5%, which isn't noticeable.
Clearly, the cooling needs improvement. At 75°C it’s already losing stability, requiring even higher voltage and causing it to spin. It must stay around mid-60s and below 70°C for optimal performance.
Besides heat, running Ryzen at 1.4v is fine, even if AMD suggests 1,425v carefully. It won't cause damage from voltage issues. The CPU stays safe from overvoltage and overheating, providing clear signals if you push too hard in either direction.
Finding a balance between voltage and temperature is key for optimal performance.
For Ryzen 14nm perhaps. For Ryzen 12nm there is some (admittedly anecdotal) evidence that you can notice wear in a few months by running a manual voltage of 1.4+V. View: https://www.reddit.com/r/overclocking/co...es_tested/ I haven't found any official max voltage from AMD, but according to a Tom's review AMD suggested a limit of 1.35V for Ryzen 14nm to ensure longevity. "AMD predicts that most users should experience speeds around 3.9 to 4.1 GHz across all cores, and advises keeping the ceiling at 1.35V if you wish your processor to last longer. Core voltages above 1.45V are thought to be manageable but will impact lifespan more noticeably."
I don't remember any case where AMD or Intel recognized or mentioned issues from higher voltages. Those concerns seem to stem from early transistor designs using various materials. There might be some heat-related damage, but no voltage limits are specified—only maximum temperatures. For example, 95°C is allowed for 2600 and 85°C for 2700x.
Changing the clock speed or voltage can harm or shorten the lifespan of the processor and other parts, and might affect system stability and performance.
