I have a 1700x and I can achieve a 3.9Ghz overclock with 1.4v. I just found this guide from my motherboard store page (GA-AB350M-Gaming 3)

https://view.joomag.com/gigabyte-am4-overclocking-guide/0517370001491902144?short

The guide recommends "most processors can hit around 4GHz on standard air coolers using a 1.45 -1.5 Vcore" It also recommends "a Vcore below 1.55v if possible"

As this is from the official Gigabyte site I was inclined to believe these voltage would be safe. They seem a little high though. I thought I would see what people thought of this guide.

Thanks,

Daniel

Up to 1.55v can be used if you have exotic water cooling and can keep temperatures low. Otherwise up to 1.45v is a reasonable value with decent AIO cooling.

There really is no such thing as a safe max voltage though. Stock voltages are the only voltages anyone can deem max safe.

Playing with voltages beyond that locks the CPU into a constant fixed voltage that raises the average V being dumped into the chip over time. Like any other ASIC, you're just gambling at that point.

Hi Matt. In the 'overclocking with AMD' video I've seen on YouTube with Robert Hallock he goes on to say that over 1.4125v risks the chip suffering from degradation in the long term. Advocates between 1.35 - 1.4v for 24/7 overclocking.

If what you say is true it gives me some leeway as I found my chip was not capable of holding 3.9Ghz even at 1.4v so I dropped it to 3.8Ghz even tho temps where in the 70-71c region.

It's a guideline not a guarantee, but if you need a little bump over 1.4v to get 3.9ghz stable...

Hey, I watched the video...He says to stay under 1.425v but in the bios he is already at 1.464v before he changed it to 1.400v?

I think there's already overclocking going on with these chips from AMD's side, if you lower clockspeed to 3.5ghz or so you can use much lower volts. If stock is 1.4-1.45V then just run it at that if it dies then it's AMD's responsiblity to replace it under warranty.
 
No such thing as a max safe voltage for a chip, you have to go system by system really. I usually try to find the best balance of temp, voltage and performance by playing with the CPU and memory.

I used an offset voltage and the voltage goes up and down when idle and under load..
