Ryzen 5 1600x voltage confusion.

rapturedheart · Feb 10, 2018

I've been having some performance issues. I initially started a post yesterday about my graphics card (GTX 1060 6GB) and someone brought up that it might instead be my CPU. My Original Post about my GPU

Well, I've watched my CPU and noticed something. Its' voltage does not look right. My BIOS (I updated it today, thinking that it might solve my issue. It didn't.) shows my 'Core' Voltage being 1.4 or more, and as high as 1.5 (almost 1.6). I've read that it shouldn't be that high at all, even if it's being overclocked, but instead should be 1.4 and lower. I haven't seen it go down in the BIOs, but monitoring it through HWMonitor, I do see it go lower when I'm not doing very much at all.

I changed my original power settings from minimum cpu usage of 100% to something lower, so it's not being stressed when I'm not actively using the computer.

HWMonitor with a game (Riders of Icarus) idle in the background:

What I'm seeing in BIOs:

Still, I don't understand if that is normal or okay at all. It's making me nervous, in-fact, because I'm having in-game stuttering issues that I haven't been able to resolve. My computer should be more than capable of having high fps in games, and fluid ones at that. While I do get high frames, my games will stutter (losing 3+ frames at any given time) and make intense games (shooters, mobas, etc) almost unplayable because my computer is hindering my own reaction time.

Any help would be appreciated, thanks.

First thing to do if not already done so is to update your Bios.
Get the Bios file from ASUS support and download to an empty USB drive that's formatted to FAT32
Rename the file to RSB350FG.CAP Insert the USB into a USB port.
Go into Bios and use your EZ Flash3 utility to update Bios and once done remove the USB and reboot.

For tuning your Bios and for voltage control go into Advanced mode>AI Tweaker menu>AI Overclock Tuner and set to Manual.
Next select your Memory frequency for 2400MHz.

Your CPU VCore is too high at 1.49V and should be around 1.25V for stock frequency.
Find your VCore settings and manually change to 1.25V to try. (maybe in the DIGI+ menu)
Reboot and Stress test the system.

If all OK and stable then your ready to Overclock if you wish for better performance.

I've updated BIOS (did that today, as I stated in my post)
I've also selected my memory frequency correctly.
Do you know where the DIGI+ menu would be for my ASUS motherboard bios? I've looked through my bios many times and don't remember ever seeing that.

There is a picture description off the varios menus on page 3.3 of your MB manual.

So... I kind of wish you had told me what to do when I really got there. It took trial and error of numbers, and constant resets to see what settings got me where. I did get to 1.250v, which is what I guess you were talking about. That was under VDDCR CPU Voltage offset, btw.
Still, though, my voltages are not doing what they're set to do at all!

I've never been so confused in my entire life. To think, I'm going into Information Technology. :fou:

DIGI+ menu looked like this for me:

Information that was shown to me when I could manually set the voltage. It says 1.72000V max... what?!

Additionally, I haven't stress tested it yet. I'm deathly worried my computer will just cease to exist if I do with how unstable the voltages are. As I speak, HWMonitor has shown them bouncing.

What program should I use to stress test my CPU anyhow?

EDIT/UPDATE: Within 15 minutes (or less) it crashed. No warning. Everything froze. I had to turn it off by the power button and I just reset the setting to AUTO like it has been for the time being. I'm going to be honest, I have no idea what I'm doing. :\

OK don't panic rapturedheart

It will become second nature after a while. You just need some explanations of what Bios settings do. Just don't make arbitrary changes without this understanding, especially with Voltages as you can do damage.

CPU Core Voltage (SVI2 TFN in HWInfo64) value is the voltage measured by the Voltage Regulator, which is supplied to the CPU (as VRM output). This voltage is then reported to the CPU and evaluated using telemetry functions.
VCore or VDDCR CPU is a measurement of the same voltage rail, but by the mainboard logic (ITE chip).

There are 2 packages you should get to stress test your system and to accurately measure system temps and voltages. HWInfo64 and AIDA64 which is free for a month. Put both on your desktop and run AIDA64 stress test for 10mins and take screenshots at the 10min mark for analisis here.

Bring your Bios back to default and clear CMOS so I can see what's going on at stock frequency.

Here is a good youtube vid and It is correct for your system at stock.

And ofc JJ is always good to watch. https://www.youtube.com/watch?v=pBmVf0S4UDAnd another that may help: https://www.youtube.com/watch?v=ZhaBrf5Ns10 I do not however advocate Overclocking using Windows software. All OCing should be done in Bios.

I appreciate your help a lot, don't get me wrong. I don't want to come off as angry or mean, or even rude. I've had a really bad time with this computer since I've had it. Little to no enjoyment has been had with it.

But I'd like to know what we would be achieving with me clearing CMOS. I've had this voltage issue since the beginning (which means, all default settings by the manufacturer, at that time.). I've spent so much time with the BIOS, and if I'm honest, I feel like that would just be more time spent on doing something that will not resolve anything but instead cause me to waste time and potentially cause more harm than good.

I'm not the only one having this issue, or the only one that's had this issue. I even have a friend who has a Ryzen 5 1300, and she's been having similar problems with her CPU.

I started this thread because I haven't seen anyone that's found a fix for it.

I just want my CPU to work like it's supposed to, and my computer to work like it's supposed to. Currently, it's not. Previously mentioned, the stuttering is terrible, making the primary usage of this computer (for gaming and college work).

BTW that "JJ" video you linked does not work for me?

Core voltage on Ryzen 1700x

MeanMachine41 :

I replied to you before, last night, but I've changed some settings that I saw others mention in regards to unstable voltage spikes. In addition, I manually set my RAM Timing, and Frequency.

Changes I made:

Manually set RAM Frequency and Timing (rather than using D.O.C.P as before)
Turned AI Overclock Tuner back to Auto from having Manually set RAM (mentioned above)
In AMD CBS, I disabled Core Performance Boost (as someone else stated that this fixed their issues)
Disabled SVM Mode (which was Auto/Enabled by default)

My Core Voltage dropped from the 1.3 -> 1.5+ to now 1.188+ typically and going no higher than 1.231.

My computer has been on for well over an hour now, and has not crashed at all. I even ran a CPU stress test to see how it would do, now that it wasn't at the absurd voltages that went everywhere.

Despite how stable the voltages are now, my original complaint about my build seems to remain (seemingly worsened). My games stutter bad, especially games that are more reliant on the CPU than the GPU.
