Ryzen static all core OC - Do cores still park?

[lafrente]

I all core oc'ed the cpu at 4ghz at 1.150v

 

But I occasionally see some cores requesting 0.2V lowest. Are they still parking? And is there a problem if CPU is parking and still getting 1.150 static voltage?

Set power plan to Ryzen Performance. No core should go below 100% if power and temp saving is a problem.

I have no problem with parking unless giving a static OC of 1.150v to a core that is requesting 0.2v because its parked is a problem?

I cant imagine why it would be. Ryzen goes stock to 1,4v+ so clearly it's not too high voltage. If you're worried its to low then it depends on whether or not you have stability issues.

 

Also you shouldn't trust software voltage monitoring. I've seen 100 million volt in computers but none of them caught fire. 

If anything, use Ryzen Master it is the most accurate for Ryzen.

What I mean is, isn't giving 1.150 voltage to a sleeping core like dropping a 100kg barbel on a sleeping person? I am worried its too high, when the core is sleeping and it's only requesting 0.2v.

 

I changed the power plan to Ryzen Performance, cores still request 0.2v when PC idles a bit.

No it's not. A core simply wants to save power. Even if it does its transistors is not physically changed. What is bad is to put it under full load and then blast a lot of power to it. It will overheat. 1,1v is not much by Ryzen standards. Don't worry.

 

Use Ryzen Master. Other monitoring apps will trick the CPU into thinking there is load to a higher degree causing it to ramp up. Probably less of an issue now though but. Still RM most accurate.

Under a manual OC Ryzen cores will still park via C-states, but will not dynamically adjust frequency. The power gets gated off on a parked core, which reduces the power consumption considerable on idle.

So I can simply disable C state to prevent this from happening. If not, it'll still run at same volt, but will just pull less power. Gotcha.
