If I ran Prime95 with all cores and threads, my Auto voltage went to vCore of 1.20v. However, it's when running on single or two cores (or threads) only with Prime95 is when the vCore really shot up. We cant continue discussion on a thread I created a while ago f you like, rather than continue on this, although it does seem relevant. http://forum.asrock.com/forum_posts.asp?TID=6185 The main point for me is that temps were not bad under auto or under fixed voltage mode. This is interesting: https://forums.anandtech.com/threads/ryzen-strictly-technical.2500572/ "Understanding the voltages specified for the standard PStates can be confusing as well. That's because in the normal operating mode (i.e. "non-OC") the SMU controls the voltages automatically through the voltage controllers. For example, the P0 PState might specify 1.37500V voltage, while the actual effective voltage during the residency in this state is 1.26250V or slightly higher. This is not a glitch, but the normal operation of the CPU. Basically, the voltage specified in the MSR is just the upper limit and the SMU will automatically add a dynamic negative offset to this value, reducing the actual effective voltage. The amount of the negative offset varies depending on load and the temperature. For the tested sample the offsets were -120mV & -144mV for the two highest base PStates (3.6 & 3.2GHz). Looks like the on chip power controller does some interesting this with voltage offsets that make it hard to measure. If you are havinga hard time with temperatures though, that's a cause for concern. I am basing my assumption on low temps = a good time.

If this will stir your pot, then here comes the crazies part - with everything left @ auto I get the high Vcore when IDLING! When loaded moderately to heavily, CPU Vcore was dropping to normal operating ranges, i.e. 1.18-1.22V For whatever the reason(s) voltage regulating circuity was overshooting severely. Go figure! As for the resets - I've done many. I've tried various combinations of even seemingly unrelated settings, only to see the same thing over and over again. |

Ah, well this is interesting. Certainly not what I had. Auto setting BIOS/UEFI shows that when idle the VID and vCore(s) are all sub half a volt. It's only really when two cores/threads or less are used that the vCore goes to the 1.4+v range. Temperatures were never high at idle- The fact you say you have a high idle temp makes me wonder what on earth is going on. Note settings and reset? Well, yeah things in the manual aren't quite right, and I didn't care for the mirror inverted diagram of the SATA port labelling (despite my father seeing it as just fine), but these are nit picky little things. Sure shouldn't happen, but there are typos, vagueness and misinformation in the ASUS motherboard manual I have from the C2D system.

I don't really care about the current voltage. My issue is that with high Vcore I get high idle temp as well.
My 3.10 Sapphire Boost is also broken, so maybe it's just a mess on my side? All this is a huge driver for my rant in my other post about to love for the Taichi. I was hoping for a fast, working and stable UEFI to go with a fresh install of Win 10 FCU and 'Adrenalin'... Wishful thinking. PERSONAL THOUGHTS: I've always used ASUS mobos and I've never had any issues with them. Reading all the recent praise about ASRock and their mobos I decided to give them a try. Honestly, the X370 Taichi looks very sturdy, but the entire FW/SW support from ASRock looks like it comes from some garage shop in Taiwan. I mean, look at the friggin' English in their software and manuals. I'm not a native English speaker but at least I proof read. |

well its strange as with p state overclocking
i got 1.325 max certainly never over 1,33 and at idle it auto drops to less than .500 thats with a two button click/entry in pstate last time i played i didnt even bother with pstates and just set 39 multi and 1.325 on oc tweaker and it still down volts to sub .500 im on exact same bios v3.1 as you my EARLIER pstates used to hold at exact pstaes setting 1.306 all the time but as vumeter pointed out i wasnt worried then as there was no current either bios 3.0 or 3.1 changed something that allowed my system to now downvolt but as its not made any difference to my stability its a bonus |

(apologies for continuing a possible thread hijack) Well, the very fact that temps have dropped a little more makes me think it's not really a bad thing running at 1.30v constantly.
Interesting reading here: http://www.overclock.net/t/1628508/official-ryzen-5-1600x-1600-1500x-1400-owners-club/520 |

Sorry for the hijack! I'll try and be brief. That's the most annoying thing for me. With manual settings you are either left with unnecessary large idle Vcore, or you have to fine-tune P-states A LOT to mimic normal auto Vcore scaling with load. |

I have been finding similar things.
I am kinda of learning as I go here, so don't take what I say as coming from a well experienced and very knowledgeable fellow - am I not! :) In HWMonitor matches with HWInfo for CPU Tdie Temperature, and the vCore shown is the same as in OpenHardwareMonitor, read from the motherboard sensor. On auto on an X370 TaiChi and with a 1700X I had spikes of vCore over 1.45v when two threads were being used. When 3 or more threads were being pushed the vCore would drop down some. When all were used it'd drop to 1.2v ish. I have manually set the Core Voltage to 1.30v in the BIOS/UEFI and set load line calibration to level 2. Everything is stable and the monitored vCore flutuates between 1.280-1.312v depending on what use is occurring. I will have to get the kWh meter out to measure if there is a reduction in idle consumption, because whilst the Tdie is actually lower at idle than before (and lower under both 2T / 16T loads), it just feels strange not seeing the vCore drop down when not needed - the AMD Cool 'n' Quiet thing or C-states. However, as daytonyb has pointed out before in a longer message, the current does change. I hope you get to the bottom of the understand like I am trying to. Good luck.

Hi!
I'm afraid it's not a normal voltage for auto. I've been experiencing the same on my X370 Taichi. See here: http://forum.asrock.com/forum_posts.asp%3FTID=5973 or http://forum.asrock.com/forum_posts.asp%3FTID=6919 Unfortunately, the only 'remedy' thus far is manual Vcore or P-states... Keep the pressure! Maybe one day they will fix what's due. |

at stock and auto volts they do indeed go over 1.5 volts
try manually setting all cores to 3.8 ghz and cpu volts to 1.4 this should be nigh on certainly stable for any 1600x you can then try slowly and gradually to reduce the volts down to 1.35 or maybe a little lower |
