What's a good voltage to shoot for when OCing Ryzen? I had a first gen 1600 and that needed 1.37v for 3.7Ghz.
Now I have a 3600 and would like it to sit around 4Ghz if possible.
Voltages I see online vary from 1.1 to 1.4
To be honest, Ryzen 3rd gen actually can go for as high as 1.5V, which is normal. What many people don't realize (and this was also confirmed on an Reddit post I believe) is that the way Ryzen 3000 series work are completely different from other CPUs in terms of voltages.
And that is they do run at high voltages and are supposed to.
Here's a quote from AMD regarding the voltages on Ryzen 3rd gen:
Please note that it is totally normal for your Ryzen to use voltages in a range of 0.200V - 1.500V -- this is the factory operating range of the CPU.
And here you can read the entire post if you'd like:
to be safe you cannot exceed 1.25V !!
that could be applied to other amd cpu.Only 6% of Ryzen 9 3900X's tested by CPU retail site Silicon Lottery are able to reach 4.2GHz manual overclockwww.pcgamesn.com
So what x111 says regarding that you cannot exceed 1.25V isn't proven and the user didn't say either at what frequenzy that 1.25V would run at either?
It also doesn't exactly say anything about this, in their provided link above, that you CAN'T - Only that it can hurt the CPU in the long term by going with voltages above that.
The reason their provided article states that only 6% could achieve that manual overclock is that AMD has already more or less cranked their CPUs to the max with their Ryzen 3000 series. In other words, there's not a whole lot more juice that you can cram out of them than what you get out of the box.
But that is with literally any CPU in history. that the higher voltage you go, the warmer it will run and hence decreases it lifespan. It's one of the long term risks you take with/when overclocking.
Keep in mind though as well, that every CPU is different. You may have a so called "Golden chip", ie you might be able to have a higher frequenzy to a lower voltage than mine. It's just how the silicon works really.
For example, Glob3Tech on Youtube, he managed to get his 3700X stable at 4GHz at 1.075V. Mine couldn't, I needed 1.125V at minimum to run at 4GHz without crashing. So now I'm at 1.130V just to be on the safe side.
