Max safe CPU NB/SoC voltage for Ryzen

atomburst · February 5, 2019

I'm currently working on overclocking my memory on Ryzen, just like everyone. My kit is only rated for 3000mhz, but I got it up to 3600.. however I have yet to do stability testing. However I got it to boot and do a run of cinebench (I know not a memory test but still works good to make sure its even a little stable) however I maged to get this with some high voltage. I have dram voltage set to 1.4v and SoC voltage set to 1.2875v. After some researching, most people say the highest you should go is 1.2v so I pushed it down but it was very unstable. I'm aware SoC affects memory controllers rather than the cores themselves, but my temps are in check even with that high a voltage, so is there really any harm? Usually if I go to an unsafe level my motherboard lets me know by making the value red, and 1.2875v is still white. Thanks.

You can do significant damage to the memory controller at higher voltages even at good temps, so 1.2875v is still too high (this is debatable, AMD doesnt have official statement, some brands claim 1.3v, some said 1.2v). Some users do find better stability between the 1.05v to 1.15v range so try that.
