Yup, XFR is enabled with my P-state OC without adding any additional offset to vcore.  I'm pretty happy with it because the CPU will pump up close to 4ghz with XFR.  ]]> Fri, 15 Jun 2018 00:58:06 +0000 https://forum.asrock.com/forum_posts.asp?TID=8932&PID=52609&title=x370-taichi-pstate-vs-asrock-oc#52609 <![CDATA[x370 Taichi P-state vs ASRock OC : Overclock mode in BIOS sets a...]]> https://forum.asrock.com/forum_posts.asp?TID=8932&PID=52606&title=x370-taichi-pstate-vs-asrock-oc#52606 Author: VUMeter

Overclock mode in BIOS sets a frequency and voltage - this is fixed.  You are disabling the automatic behaviour of the system, which is to drop frequency (go into higher P-state numbers) and thus also drop voltage when not doing anything.

It'll use 1.35v all the time if that's what it is set to, but current will decrease massively when the CPU is a lower loading on the CPU.

P-State overclocking is taking setting the voltage and frequency for particular states the CPU can be in, and therefor allows for a lower voltage when in a lesser P-state (higher number).  P-0 is flat out all cores under full load.

You seem to indicate that you've kept XFR enabled?  This might very well boost the CPU and pull in more current for other sensors/controls on the CPU.  It's a really complicated bit of kit that little chip, and there are things on there that get disabled when you put it into overclock mode, but stay enabled when not.  It could be these that are drawing extra power/creating extra heat.

So I've been trying to find the most effective overclock possible.  I typically run my 1800x at 3.9ghz because it doesn't require over voltage to get there from the default 1.35v that it defaults to. When I use P-states to achieve my 3.9ghz OC, temps while under Prime95 load tend to produce a few degrees C increase at the top end.  Of course, I have it set to also turbo up to 4ghz too, but that doesn't seem to happen when running Prime95. 

If I use the ASRock settings feature instead of P-states, I set the voltage to 1.35v at 3.9ghz.  This means rather than adjusting when there is no load, it will stay at 3.9ghz, no turbo either. 

I'm wondering if anyone else has noticed this, why would the P-state OC cause it to produce a tad bit more heat if they're both set to 1.35v with the same frequency?

Also, I have the EK supremacy EVO cpu water block with a 280mm & 360mm rad for cooling.

BIOS version 4.4.
