Voltage Automatically Increasing?

[redsquirrel0249]

Tried overclocking my Ryzen 5 1600 to 3.9 GHz at 1.29 and 1.3 V, but the system kept overvolting to 1.35 and 1.36 V. This isn't a PSU problem, it's got super tight voltage control, but it could be a processor, mobo, or OS problem. Cooling is also a non-issue, as AIDA64 for 20 mins gets this clock to 59C. Below is a screenshot of CPUZ with the overvolted stats.

 

 

Let me know how I could try volting this down. I had it at 1.26 V, and Windows wouldn't start, so I know it responded to being undervolted. It started responding and then overvolting at 1.29 V.

How are you overclocking? I find software overclocking to be more open to these effects. Fix voltage in bios to prevent.

That's what I'm doing. I'm using the voltage offset on a Gigabyte AB350 Gaming 3.  think what I did is misinterpret core voltage. I think I thought it was 1.2 V but it's actually 1.25 V, so I underestimated what my offset would move it to.

Voltage offset is not what you use to fix voltage. Offset is as its name suggests, it allows you to shift the voltage up or down from what the system thinks it wants. If you increase clock, it will also increase voltage. A fixed voltage is one that doesn't change regardless. The drawback of fixed voltage is that it also doesn't drop when the CPU goes into lower power state, so the system will use a bit more power then. So advantages/disadvantages for either.

If your voltage increases when you increase clock speed, what's the point of changing voltage offset at all?

What do you mean by this? I can show in CPUZ that I can use it to control my core voltage...

What mobo do you have?

 

I'm making up numbers for example, but say the CPU when left on auto voltage does 1.20v at 3.3 GHz, and 1.30v at 3.7 GHz. If you use offset, it affects both those voltages, so +0.05v offset would give 1.25v and 1.35v respectively. If you use fixed voltage of say 1.30v, then both speeds will be at 1.30v.

Yes, but both of those would be beneath set clock and set offset voltage, right? Underclocks are irrelevant. I know it scales to the percentage of normal clock.

 

i'm asking about voltage moving according to a new set clock (which you say happens, I think it doesn't). The other claim you made was that voltage offset doesn't set fix voltage, but you just explained that it instead sets it at accompanying core clock and scales for underclocks, which is what I meant in the first place. I wasn't referring to scaling. That's odd that fixed voltage doesn't scale, though, that seems like a problem.

I guess we have a misunderstanding somewhere... want to start again? Might still help to know what mobo you have.

start again?

You'd need to reread the posts to clarify your confusion... at any rate, I could care less since I realized I had the wrong stock voltage: that was the main concern.
