Safe CPU voltage?

[Guest]

I just got an aftermarket cooler for my CPU (Ryzen 3 2200G), and am now trying to overclock it. What is a safe CPU Core Voltage? My motherboard (Asrock B450 Pro4) has a limit at 1.45V, but is it safe to do something like 1.44V or 1.425V to get higher clock speeds? The default is 1.4V and I'm not touching the SOC voltage, and I have quite a bit of headroom for overclocking temperature wise.

Nobody is going to say yes when it's written all over the place in the warranty papers. lol

 

So no, nothing past stock default is safe and everything is at your own risk. But for reference......

 

Lower binned silicon generally takes more voltage to reach a higher clock speed.

1.410v is what I use to achieve 4.1ghz 2700X.

 

Low end silicon 220ge for example, needed 1.57v to reach a cpu-z max frequency of only 4391mhz SMT disabled.

When that chip stops overclocking, that's about where your wall is. I'd back it off 100mhz. 

(those are examples, do NOT try that voltage. You will damage the processor.) sry hv 2 say it.

 

So 1.400v is about right at the ledge of diminishing returns. 50 - 100mhz, you'll hardly see much improvements. But you'll have to make that call. 

4ghz over 3.9ghz worth 1.45v.ish If you can keep load at 70c or less, I'd say go for it.

Thanks for the reply. I was able to get 3900MHz stable at 1.425V, but wanted to see if I could get 4GHz since I have plenty of temperature headroom ~64C avg full load at 1.425V. But nothing less than 1.45V wasn't stable, and 1.45V turned the font red and gave warnings.
